Lane mergers in packaging lines: when they are needed and which one to choose

Converging multiple product lanes into a smaller number of lanes may seem like a simple operation. In reality, the way products are collected, timed and delivered to the downstream machine can have a significant impact on the consistency of the entire process.

This is why designing a lane merger is not simply a matter of considering line speed. First of all, it is necessary to understand how the product behaves: its shape, stability, fragility, ability to run in contact with other products, and the pitch required by the downstream machine are all factors that help define the right solution.

Based on these parameters, M.H. Material Handling designs the merging configuration best suited to the characteristics of the line and the product.

The first criterion is the product: can it withstand accumulation?

Even before speed is considered, the assessment starts with the product and its ability to withstand accumulation.

A product that can tolerate accumulation can withstand the pressure generated by products touching and pushing against one another. Boxes, trays and products stacked in tightly packed formats fall into this category.

A fragile product, or one prone to overlapping, cannot withstand this type of stress, and a pressure-based system could compromise its integrity.

This is why resistance to accumulation is the first factor to be assessed, as it determines whether a pneumatic or dynamic lane merger is required even before line throughput is considered.

There is, however, one useful exception to bear in mind.

Even with a product that can withstand accumulation, the presence of many formats with significantly different widths often makes a dynamic solution preferable. This avoids format changeovers using adjustable or automatically controlled guides and, because the products do not come into contact with one another, eliminates the risk of misalignment.

Pneumatic, DU Series or HP Series: the right technology for each product

A pneumatic lane merger is the simplest and most cost-effective solution, but it is suitable only for products that can tolerate accumulation.

It operates using gates on the infeed lanes, which release the product rows in sequence, and requires two conditions: the products must be able to withstand pressure during accumulation, and the downstream machine must be capable of receiving products in a continuous train without being adversely affected.

The second requirement has a specific technical reason. At the outlet, the products are close together or touching. When this train reaches the downstream machine, the instantaneous speed seen by the machine is therefore twice the average speed. Either the downstream equipment must be able to handle this, or the flow must be normalised using a deceleration conveyor followed by an acceleration conveyor, at the cost of a larger footprint, two additional motors and more complex control logic.

The pneumatic solution is also well suited to a particular application: where the carton itself is the primary package, as is common in the pasta industry, in the section between secondary packaging and the case packer, where the product can be accumulated.

When, on the other hand, the product is delicate or must be handled without contact, dynamic lane mergers are used. M.H. offers two series.

The DU Series merges products by reducing the number of lanes through anti-overlap timing belts operating at controlled differential speeds, one for each infeed lane. Products are handled individually and without contact, making the system suitable for fragile products or products prone to overlapping, at speeds of up to approximately 240 pieces per minute.

The HP Series is the evolution of the DU Series, developed specifically for high-speed flow-wrapping lines and for connections between primary and secondary packaging. In this case, pressure is completely eliminated because the products must never come into contact. Each item is individually timed by means of a multi-belt system with independent brushless drives for every infeed lane, combined with blower-generated vacuum for higher acceleration rates, reaching up to 600 pieces per minute at the outlet. In flow-wrapping applications, precise product timing is essentially mandatory, as it is the only way to prevent products from overlapping.

Outlet pitch: a detail that should not be underestimated

As speed increases, it becomes essential to achieve the most consistent possible product pitch at the outlet of the lane merger, because this determines how the downstream machine receives each item.

A product flow delivered in trains can push the downstream machine beyond its production limits because of the instantaneous speed peaks described above. Individual product timing, on the other hand, controls the distance between packs and transfers them without contact, reducing the risk of jams and overlaps.

The choice always starts with the product

In every case, the starting point is always the product. The first step is to determine whether it can withstand accumulation, then assess its fragility and shape, the required production rate and the number of lanes to be merged, and finally the type of downstream machine, particularly whether it is a flow wrapper positioned between primary and secondary packaging.

The right technology emerges from these answers: a pneumatic lane merger for products that can withstand pressure, the DU Series for products requiring contact-free handling, and the HP Series for high-speed flow-wrapping applications.

At M.H. Material Handling, we manufacture material-handling systems and efficiency solutions for packaging lines in the food industry and related sectors. Over more than forty years of field experience, from food & beverage to pharmaceuticals and packaging, we have developed the expertise required to identify where lane merging can make a real difference and where it is unnecessary. On this basis, we design customised pneumatic and dynamic lane mergers from the DU and HP Series, starting with an analysis of the production line.

If you are planning a new line or a revamping project and lane merging is still an open issue, we can assess it together to identify the most suitable configuration.

Hygienic Design vs Wash Down qual è il sistema più adatto alla tua linea

Hygienic Design vs Wash Down: Which system is right for your line

It’s 6:45 a.m. The line is down for end-of-shift cleaning. The operator directs a high-pressure water jet onto the conveyor, moving the lance from left to right, then shuts off the valve.

On the surface: clean.

In reality: the frame beneath the belt has three enclosed corners where water never reaches. Organic residue builds up there, day after day.

This is not a cleaning issue. It’s a machine design issue. And the difference between a line that passes a hygiene audit and one that barely gets through – every single time – comes down to this.

Washdown: effective on paper, limited in practice

Washdown – high-pressure cleaning with water and detergents – is the most common response to contamination risks in food processing lines.

It’s relatively inexpensive to implement and provides an immediate sense of control.

The problem is that it only works if the machine has been designed to be cleaned. If the frame has enclosed cavities, if chain returns are inaccessible, if joints retain moisture, the water jet doesn’t solve the issue. It just relocates it. The result is increasing consumption of water and chemicals, longer downtime, and a real risk of cross-contamination. Meanwhile, the quality manager signs off on sanitation reports that, in practice, cannot be fully guaranteed.

Hygienic Design eliminates the problem at the source

Hygienic Design, when applied to machinery, is a design approach that starts with a specific question: how can this machine be thoroughly cleaned, under real operating conditions, with the available personnel, in the shortest possible time?

A conveyor built with this logic features open-frame construction, sloped surfaces for effective drainage, tool-less disassembly, food-grade certified chains, and materials resistant to aggressive cleaning agents.

It’s not “washable” because someone claims it is – it’s washable because there are no areas where residue can accumulate.

From an operational standpoint, the impact is significant: sanitation downtime is reduced, water and chemical usage decreases, and contamination risk is minimized. Hygiene audits become a natural outcome of the design – not a recurring uncertainty.

Not every line carries the same risks – that’s why choosing the right approach matters

In practice, the choice between a Hygienic Design approach and a Washdown system depends on where the conveyor is positioned within the line and the type of product it handles.

For unpackaged products – fresh food, meat, dairy, bakery – the contamination risk is extremely high. Here, Hygienic Design is the minimum requirement.

Monolithic belts with no internal fabric, such as the SaniBelt line we design at MH, are specifically developed for this purpose. They have no exposed textile surfaces that can retain residue and can be cleaned in just a few minutes.

When handling packaged products, still within a white area, requirements change. A washdown design can be sufficient, provided stainless steel construction is maintained and flat surfaces and enclosed cavities are avoided. In this case, tool-less belt removal for cleaning is no longer essential. Moving into grey areas, hygiene requirements can be relaxed further, with greater emphasis on robustness and throughput. Depending on the environment, you may still opt for stainless steel frames – for example, where floors are regularly washed with water – or choose anodized aluminum structures where this is not required.

3 practical steps to quickly identify critical points in your line

Before deciding whether to upgrade a single conveyor or redesign an entire section, you need a simple method to identify where the real issues lie.

Here are three key aspects to assess your current situation:

The first step is to map the line by hygiene risk level

Open product, packaged product, and transition zones. For each area, define the conveyor type and the current cleaning regime.

The second step is to inspect critical design points

Enclosed frame corners, cavities beneath chain returns, joints between modules, and moisture-prone areas. If you can’t reach a spot with a cloth, water won’t clean it effectively either.

The third step is to measure actual sanitation time

If it exceeds 20 minutes per conveyor in high-risk areas, you have a design problem. And remember: no stricter cleaning procedure can compensate for a design flaw.

A layout is designed once -but it’s lived with every day

The issue is that most companies address hygiene only when the problem is already visible: a difficult audit, a product recall, or uncontrolled sanitation costs. At that point, the room for action is limited.

At MH Material Handling, we have been designing conveying systems based on these principles for over forty years. From the Saniflex belt for high-risk areas to the BAT system with USC chain for high-speed lines, every solution starts from a real analysis of the customer’s operating conditions – not from a standard catalog. If your sanitation times are too long, if hygiene audits are always uncertain, or if you are designing a new line, get in touch. We can analyze your processes together and identify the most effective solutions to protect product safety and reduce operating costs.

Cosa succede quando il nastro trasportatore non è quello giusto

What happens when the conveyor isn’t the right one?

At first glance, it may seem like a small detail, just a component connecting one machine to another, nothing more.

In reality, the conveyor is the heart of the line: efficiency, hygiene, safety, and ultimately the quality of the product reaching the consumer all depend on it.

Yet too often, its selection is underestimated, as if one belt were as good as another. But that’s not the case.

Each application is different, every product has its own characteristics, and each plant has its own criticalities.

Treating the conveyor as a “standard” element means opening the door to unexpected downtimes, contamination, waste, safety issues, and hidden costs that grow over time.

A significant share of line stops doesn’t stem from mechanical failures but from synchronization and accumulation problems, a clear sign that conveyors impact production continuity much more than people think.

When the product is “naked” fresh or dry is not enough

Talking about “naked” products means addressing very different worlds. A dry croissant is not the same as a honey-covered bar, just as a filled cake slice cannot be compared to a cracker.

In the fresh sector, hygiene is paramount. Belts must be washable, cavity-free and easy to sanitize. Belts with internal fabric layers are not suitable: if the fabric emerges, it becomes impossible to clean properly.

That’s why monolithic belts are used, more rigid and less flexible, but capable of ensuring the highest hygienic standards.

In the dry sector, the range is broader: brittle products such as biscuits or crackers fit well on modular chain conveyors, which allow easy removal of crumbs.

But when coatings, creams, or jams come into play, PU belts are required, surfaces that can be scraped clean without damaging the belt.

Each product type therefore requires a targeted evaluation.

Packaged products, but where in the line?

Even a packaged product raises specific questions: is it located in a white zone or a grey zone? Does it require washdown capability or not?

Are high speeds, tight transfers, or low noise levels needed?

In general:

  • The tabletop chain conveyor is ideal for heavy loads, high speeds, and complex layouts.
  • The modular chain conveyor offers greater flexibility and smaller wrap diameters, but it’s less robust, has wider curve radii, and requires more maintenance attention.

If we’re in a washdown area, the structure matters too: at least the legs must be in stainless steel, if not the entire frame.

The choice, therefore, concerns not only the belt, but the whole operational context.

The invisible factors that make the difference

Beyond product features and packaging type, there are less visible but decisive variables:

Belt position

On the floor or overhead?

Overhead systems prioritize robustness, since maintenance interventions are more complex.

On-floor conveyors, instead, prioritize operator safety, requiring reduced-pitch chains to minimize risk.

Maintenance

How often will the belt need to be serviced? High frequency calls for easily removable and sanitizable designs.

Format variety

If the line handles multiple product types, flexible and adaptable systems are essential.

Finally, one basic principle must not be forgotten: machines never work in perfect synchronization. That’s why accumulation systems (buffers) are necessary to guarantee continuity and prevent line stops.

At M.H. Material Handling, we know these complexities well. For nearly forty years, we have been designing tailor-made conveyors for every type of line, product, and requirement – from fresh to packaged good.

Our solutions always start from listening: we don’t begin with a standard catalog, but with a real customer problem.

Whether it’s about handling a delicate product, freeing up floor space for operators, or optimizing flows in limited spaces, every project is co-designed together with the customer.

From the washdown SaniFlex line to the BAT system with USC chain, up to the ModulFlex conveyors with modular chains ,each technological choice follows a clear logic: transforming daily challenges into efficient, safe, and long-lasting solutions.

For us, automation doesn’t mean selling a machine, it means designing together the right answer to a real need.

Hygienic Design da semplice esigenza a requisito strategico per l’industria alimentare

Hygienic Design: From Basic Need to Strategic Asset in the Food Industry

In the food industry, hygiene isn’t just good practice—it’s an essential requirement for ensuring safety, quality, and regulatory compliance.

But is designing machines that are “easy to clean” really enough?

The answer is no.

Preventing contamination and protecting the end consumer requires a much more advanced, structured, and systematic approach.

That’s why today we’re talking about Hygienic Design: a set of construction criteria, design choices, and specific materials developed to eliminate risk areas, simplify sanitation, and guarantee the highest standards in food safety.

Hygienic Design in the Spotlight: Why It’s Transforming Food Production

In recent years, tighter regulations and a growing focus on food safety have brought Hygienic Design to center stage.

Food manufacturers are dealing with increasingly automated processes—and maintaining high hygiene standards throughout the entire line, including the most complex phases like internal transport and handling, is now a top priority.

Key challenges include:

  • Preventing cross-contamination, both microbiological and chemical.
  • Ensuring fast and effective cleaning of every product-contact surface.
  • Reducing water and detergent consumption to meet both sustainability goals and cost control.
  • Complying with EHEDG (European Hygienic Engineering and Design Group) guidelines, now a benchmark across the European industry.

Hygienic Design Is More Than Just Stainless Steel

Many think Hygienic Design simply means using stainless steel—but that’s only part of the story.

A proper approach starts with material selection but extends to surface geometry, accessibility for cleaning, the absence of gaps and stagnation areas, and tool-free disassembly of washable components.

Among the most common materials, AISI 304 stainless steel with bead-blasted or 2B finishes is standard for frames and load-bearing structures.

But plastic materials also play a key role. For instance, M.H.’s Saniflex system uses polypropylene chains with polyketone pins—highly resistant to the chemical agents used during sanitation.

Saniflex: Designing Hygiene with No Compromise

M.H. Material Handling developed the Saniflex system specifically to meet the toughest requirements of the food industry, particularly in dairy production.

In these environments—where processing fresh and packaged cheese demands absolute cleanliness—standard solutions simply aren’t enough.

Saniflex stands out thanks to:

  • Fully open frame design that prevents build-up and supports efficient drainage.
  • Tool-free removable components for fast and easy daily or deep cleaning.
  • Chains resistant to aggressive detergents but fully compliant with food-grade regulations.
  • Reduction in water and detergent use compared to traditional systems.

The result?

A solution that enhances productivity, guarantees hygienic safety, and supports environmental sustainability targets.

Invisible Contamination: The “Forever Chemicals” Risk

Hygienic Design isn’t just about bacteria and mold.

Today, manufacturers must also consider chemical contamination from persistent substances like PFAS (per- and polyfluoroalkyl substances), often called “forever chemicals.” These may come from the environment, industrial coatings, or even the detergents used on production lines.

Designing equipment that’s easy to clean also means reducing surface exposure to these chemicals.

With Saniflex, manufacturers can:

  • Reduce washing cycles.
  • Use gentler, less aggressive detergents.
  • Minimize the risk of transferring harmful substances onto the product.

When Hygienic Design Becomes a Competitive Advantage

Hygienic Design is a strategic investment that brings measurable benefits:

  • shorter downtimes,
  • longer equipment lifespan,
  • lower cleaning costs,
  • stronger food safety,
  • regulatory compliance.

At M.H. Material Handling, these principles are a cornerstone of our engineering.

With solutions like Saniflex, we combine technological innovation, operational efficiency, and full adherence to the strictest international guidelines.

Chocolate Production: How to Optimize It with Counterplate Transport Lines

In the world of chocolate production, efficiency and process quality are essential to meet the expectations of an increasingly demanding market. This need has become even more pressing due to the significant rise in cocoa prices in recent years, pushing companies to optimize every stage of production to remain competitive and profitable.

Among the systems that ensure smooth operations, counterplate transport lines play a crucial role. These systems, designed to support product handling across various production phases, are a prime example of how industrial engineering can enhance performance and reliability in manufacturing processes.

This method is particularly suitable for “hollow products” such as chocolate eggs, bunnies, and other molded figures, as well as pralines—especially irregularly shaped or spherical ones. Given their shape, these products can roll erratically on traditional conveyor belts, making counterplates the ideal solution to ensure proper positioning and stability throughout all production phases.

From Molding to Packaging: How Chocolate Delights Are Made

The chocolate production process is divided into several interconnected stages, all optimized by counterplate transport lines.

1. Molding and Stabilization

The process begins with molding, where raw material is poured into molds to achieve the desired shape. Once solidified, the product is transferred onto counter-molds—mirror structures that ensure product stability and integrity. These counter-molds, known as counterplates, are essential for securing and organizing products during subsequent processing phases, contributing to a smooth and efficient production flow.

2. Feeding the Packaging Machines

At this stage, the counterplates, with products securely nestled in their cavities, are transported to the packaging machines. Here, automated systems like Cartesian or anthropomorphic robots pick up the chocolate pieces for primary packaging. This phase does more than protect the product: the packaging is also designed to enhance the chocolate’s visual appeal, making it ready for distribution and sale. Counterplate transport lines play a vital role in managing flows toward multiple packaging machines, preventing bottlenecks with accumulation systems that reduce waste and ensure operational continuity even during machine downtime.

3. Recycling Counterplates

Once the product transfer is complete, the empty counterplates are reintegrated into the production cycle. Tipping and shaking systems ensure no residues remain, while the return process often takes place on separate levels to optimize space. Before demolding, buffer systems regulate product flow to maximize efficiency.

Advanced Solutions to Optimize Production

In addition to ensuring product transport, counterplate lines incorporate innovative devices that improve efficiency and versatility.

  • Elevators: Lift the plates for precise positioning on the transport line.
  • Buffers: Accumulate products to prevent interruptions in the production flow.
  • Tippers: Flip plates for correct positioning at each phase.
  • Bypass Systems: Temporarily redirect flow to maintain production continuity.
  • Alignment Devices: Ensure every chocolate piece is perfectly oriented for packaging.

Why Are Counterplate Transport Lines Essential?

These systems not only guarantee the final product’s quality but also optimize resource and space management. They help maintain high hygiene standards, minimize waste, and increase overall productivity. Their ability to adapt to various production needs makes them indispensable for chocolate manufacturers.

What to know about product handling devices

Sometimes very little is needed to solve even big problems. Such is the case with product handling devices, which, despite their small size, can make all the difference in a packaging line.

It is often thought that large, bulky and expensive machinery is needed to make a packaging line efficient or faster; product handling devices “dispel” this myth and, indeed, confirm the exact opposite.

I start with a premise: these are machines that in their small footprint encapsulate high technological know-how, the result of a detailed analysis of the company’s needs.

I think it is important to make this clarification since, in the packaging industry, one of the challenges is precisely to create value in small spaces through a high-tech approach.

In fact, I always repeat it and I will never tire of repeating it: available space is one of the worst enemies of product packaging; everywhere, and in Italy especially, there is a lack of square meters to dedicate to product packaging operations. Therefore, solving a problem or making a line more efficient by taking up little space is a great added value.

When to resort to a product handling device?

Product handling is one of the most common applications in packaging lines. In fact, the need to rotate products on all possible axes is common to many companies and can be easily met through these devices.

I reiterate easily because, given the size of the devices, they can usually be fitted inside the plant without too much difficulty.

As I said, these are very common devices, capable of solving multiple problems. Let us look at some typical situations.

1) It often happens that the configuration of the product exiting the upstream machine is different from the one required by the downstream machinery; in this case, a product handling device allows the product to be rotated, avoiding inefficiencies or continuous interruptions.

2) Another typical scenario occurs when labeling or marking is required on a different side of the product than the side by which it exits the packaging machine; therefore, product rotation is required prior to this process.

3) Imagine the advantage of being able to “squeeze” flowpacks the packs coming out of a vertical machine so that the pack height is within a uniform tight tolerance, which will allow the downstream case packing machine to produce a smaller box.
A few millimeters gained in all directions that translates into less packaging material, more cases per pallet, and thus, over time, more products per truck. An overall savings that over time will ensure greater sustainability across the board.

As you may have understood from this quick roundup of situations, there are many possibilities and consequently many features of the device to be inserted.

In fact, when I am confronted with a client about these devices I am wont to make it clear how critical device customization is; it is essential to start with a detailed analysis of:

  • specific needs imposed by the line;
  • weight of the packaged product;
  • dimensions of the package;
  • speed of the packaging line.

Last, but obviously the most important, are the axis and direction of rotation of the product. The best way we have found to avoid confusion is to use terminology inherited from boating, so we speak of ROLL to identify the rotation along the axis of motion, Yaw for those along the vertical axis, and finally BECK for the axis transverse to the motion (in English Rolla, Yaw, Pitch).

Only with all this information in hand can you put in a truly efficient product handling device that can make a difference on your packaging line.

At M.H., we have been designing and manufacturing these types of devices for thirty years, supporting companies that need to optimize and make their packaging lines more efficient by offering innovative and technologically advanced solutions.

Maximize capacity, minimize damage: A guide to buffering systems for cylindrical products

In industrial production, buffering systems play a crucial role in ensuring optimal space management and uninterrupted production.

When handling cylindrical items such as bottles, aerosol cans, and vials, it becomes essential to adopt systems specifically designed to manage disparities in production flow across different processing stages. These systems must balance upstream production with downstream demands and adapt agilely to the varying speeds of packaging machines.

The primary goal of these systems is to ensure that every operational phase integrates seamlessly, even in the presence of fluctuating rhythms. This synchronization is fundamental to maintaining the quality and integrity of items throughout the entire production cycle.

Such consistency and balance in the flow minimize the risk of clogs or unexpected delays, ensuring efficiency and resilience that are essential for the success of any packaging line.

Let’s now take a closer look at the features and advantages of the three buffering systems suitable for cylindrical products: serpentine, recirculating, and reservoir.

  • Serpentine Buffer Systems

Serpentine buffer systems represent the most straightforward and cost-effective solution for managing short stoppages

The adjacent arrangement of conveyor belts, moving in opposite directions, facilitates the transfer of products between different tracks, ensuring sufficient space for accumulation. The speed of the belts is adjusted according to the desired spacing between products, guaranteeing an efficient and safe process.

These systems are particularly useful for “emptying” upstream machines, allowing continuous production without interruptions.

  • Recirculating Tables

For greater accumulation capacity and optimal use of available space, recirculation tables offer an advanced solution.

With a central transit belt flanked by wider belts moving in the opposite direction, these systems efficiently manage product accumulation, effectively handling longer production interruptions.

  • Reservoir Tables

When production needs require product accumulation for extended periods or in the presence of frequent format changes, reservoir tables are the ideal solution.

These systems, with their wide and bidirectional configuration, can accommodate a significant quantity of products, effectively functioning as a buffer.

Solutions for Cylindrical Products with Special Requirements

In addition to standard buffering systems, there are products that, due to their unique shapes, require extra care.

Truncated conical products or those with non-standard circular sections often require ingenious solutions to ensure their integrity during accumulation.

For these special items, we implement proactive measures such as polycarbonate containment covers, which effectively prevent the risk of overlapping or part separation. These precautions are essential for maintaining the excellence and precision of the product up to the final stage of the process.

Successful strategy: Choosing the right buffering system for your production line

Buffering systems for cylindrical products are a key component in optimizing production processes. By implementing specific technologies—such as serpentine systems, recirculatiing tables, and reservoir tables—you can not only maximize production capacity but also preserve the integrity of each individual item.

Attention to the specific needs of various product types ensures tailored solutions that effectively address the challenges of modern industry.

In this scenario, making a well-informed and judicious choice of accumulation systems is crucial not only for solving operational problems but also for optimizing your production line, ensuring a rapid and tangible return on investment.

Refining production requires not only the right tools but also the insights necessary to utilize them effectively. This is where our MH Solution Scan comes into play: an in-depth diagnosis to analyze and optimize your packaging line. This advanced technology examines current processes, identifies areas for improvement, and suggests the most suitable solutions to increase efficiency and reduce costs.

Conveyor: much more than just a connection between two machines

What happens when the connection between the machines in a packaging line is not designed correctly?

The risk is that slowdowns, accumulations, micro-stoppages and disruptions in the flow may occur, affecting the efficiency of the line and, over time, the overall performance of the plant.

This is the idea behind the new video series from ConveyorU, the M.H. Material Handling Academy dedicated to intelligent product handling in packaging lines.

Guiding you through this journey are Convy, the Academy’s mascot, who asks the questions of those who work in production plants every day, and Luca Fontana, CEO of M.H. Material Handling, who answers based on forty years of experience in line design.

In this first episode, they address an apparently simple question: why are conveyors so important?

As the video shows, the value of a conveyor depends on how it is integrated into the line, the required speed, the operating conditions and the specific production requirements.

The required characteristics also vary significantly depending on the industry: a line dedicated to food or pharmaceutical packaging has different priorities compared to an application in logistics, mechanical engineering or the automotive industry.

This is just one of the topics covered by ConveyorU, a journey dedicated to the different aspects of product handling and packaging line efficiency.

Do you want to improve the efficiency of your line?

Every line has different conditions, products and critical issues. To identify areas for improvement, it is therefore necessary to analyse the process as a whole, looking at how the machines interact and how the product is handled.

The M.H. Material Handling team can help you assess your line, identify any critical points and develop a solution based on the actual needs of your plant.

Less Packaging, More Line Problems. The hidden cost of sustainability on your machinery

It happens for different reasons. Sometimes it is a decision made by the purchasing department aimed at reducing costs. Sometimes the end customer requests less plastic. Sometimes it is compliance with new European packaging regulations, such as the PPWR Regulation. Sometimes it is all of these things combined.

Whatever the reason, when the primary film gets thinner, the package becomes lighter and more deformable.

On the conveyor, however, this means less stability.

On the conveyor, just a few microns change everything

A 28-micron film creates a very different pack from a 40-micron one. Lighter and more flexible, it is more affected by any type of contact – whether with product guides or with other packs in accumulation zones. The risk of deformation or overlapping inevitably increases.

Downstream, this results in micro-stops and scrap, and often in complaints from customers receiving damaged products.

The packaging machine continues to run as usual, but the entire section between production and packaging is no longer suitable for the new format. As a result, speeds, chain type, side guides, and contact surfaces all need to be reconsidered, because the entire conveying section must be recalibrated according to the new mechanical properties of the pack.

The buffer that worked yesterday may no longer be suitable today

An accumulation system is designed based on the real parameters of the format, such as weight, rigidity and pack dimensions. When these parameters change – for example, when switching to lighter or more flexible packaging – the behaviour of the product inside the buffer changes accordingly. In a pressure-based system, a less rigid pack therefore risks deformation or damage during accumulation if everything is not correctly set.

The MH Material Handling BAT Buffer operates without pressure on the product and is designed to be flexible and configurable across multiple formats and layouts. This makes it suitable even for lightweight and delicate packs.

However, flexibility does not mean that a single setup works for everything: if the format changes significantly and the buffer is not readjusted, the risk of jams and damage remains.

A useful rule of thumb during the design phase is that a buffer should hold between 2 and 5 minutes of production: the time needed to absorb the typical micro-stops of the line without losing productivity. With lighter formats, however, it is worth recalculating both the effective accumulation capacity and the discharge speed, considering that the downstream machine should be able to run at least 10–20% faster than average to recover the accumulated product.

Downstream of the packaging machine is where the real game is played

When package weight and rigidity change, the requirements of the downstream section of the primary packaging also change. All downstream mechanics – aligners, phases and lane combiners – are suddenly handling a product that is no longer matches the original design assumptions.

The packaging machine keeps running, but the downstream area – the one nobody actively monitors – is where efficiency is lost.

That is why every format change requires a check of the feeding and conveying systems, and it must be done before problems arise.

How to adapt the line without stopping production

The process starts with mapping the characteristics of the new package: weight, dimensions, rigidity and coefficient of friction.

The new format is then tested across every section of the line, not only on the packaging machine, because each section reacts differently and must be checked individually.

The most important step is to involve the conveyor supplier already during the design phase, not once the problem has already become evident.

Working in stages – validating one section at a time before moving on to the next – allows production to remain active while reducing risks.

The format changes. The line cannot stay the same

When a company decides to reduce packaging weight or thickness – whether to cut costs or to meet sustainability requirements – the decision usually starts in the purchasing department. A thinner film is selected, the price is negotiated, and the specification is updated in the system. And then it stops here.

The problem is that no one checks the impact of that change on the packaging line. The process engineer is not involved, at least not immediately. They are called in weeks later, when machine downtime starts to increase, scrap rises, and OEE drops without an obvious cause.

The machine is the same. The product is the same. However, the packaging has changed, and that change affects the entire line: from packaging to accumulation, from conveying to palletizing.

For over 40 years, MH Material Handling has been designing conveying and accumulation systems. We work on layout analysis, buffer configuration, feeding system adaptation, and the integration of new solutions into existing lines, ensuring everything works with today’s format, not yesterday’s.

If you are considering a format change, or if you are already facing issues after a reduction in material thickness, let’s talk before inefficiencies become the norm. A preventive technical discussion costs far less than a stopped line.
