Today’s food packaging lines are increasingly fast, automated, and high-performing. Individual machines can reach speeds and accuracy levels that were unthinkable just a few years ago.

And yet, in many plants, higher performance does not translate into a real improvement in overall line efficiency.

The reason is simple: a packaging line is not the sum of its machines, but a dynamic system where each station directly affects the others.

It is precisely within this delicate balance that the most common issues arise: unplanned downtime, micro-stoppages, and cascading slowdowns.

In this context, accumulation systems are no longer just an accessory—they are a key element that can truly make the difference in packaging line performance.

The accumulation system: the “lung” of the line

A useful way to understand the role of accumulation is to think of it as the “lung” of the packaging line—this is exactly how we at M.H. Material Handling define it.

An accumulation system is designed to “give breathing space” to the line, absorbing speed variations and temporary stoppages while maintaining a continuous product flow.

When a downstream machine slows down or stops (for example, during a reel change or adjustment), the accumulation system buffers the excess product, preventing upstream machines from stopping.

When the line restarts, the accumulated product is released in a controlled way, allowing partial recovery of production without stressing the system.

A simple principle, yet with a significant impact on overall line productivity.

The problems accumulation systems solve

In many packaging lines, certain inefficiencies are often accepted as unavoidable. In reality, they are frequently the result of missing or improperly sized accumulation.

1. Reel changes and line stoppages

Every film or packaging material change requires a machine stop. Without an accumulation system, this stop propagates across the entire line, halting even the sections that could otherwise keep running.

2. Different machine speeds

It is rare for all stations in a line to operate at the same speed.

Performance differences generate continuous micro-stoppages that negatively impact the entire process. Even small variations create instability, increasing component wear and reducing process predictability.

This is exactly where accumulation systems come into play.

Why accumulation is even more strategic today

While accumulation used to be considered optional, it has now become a strategic design choice. This is due to several factors:

• higher line speeds
• greater product variability (formats and packaging types)
• limited available space (especially in existing plants and especially in Italy)
• increasing pressure on overall system efficiency.

In this scenario, accumulation becomes a balancing tool, enabling smoother and more predictable product flow.

How to choose the right accumulation solution

One of the most common mistakes is to consider accumulation as a module to be added at the end of the line. In reality, its effectiveness depends on how it is designed and integrated into the system

Key factors to consider include:

• product type and its resistance to pressure
• line speed and differences between machines
• available footprint and vertical space
• required operating logic (FIFO or LIFO)
• working environment (e.g. maintenance and cleaning requirements)

Only by starting from these elements is it possible to define the most suitable accumulation solution, avoiding compromises that become costly over time.

Ultimately, designing accumulation means designing production continuity and line reliability. It cannot be treated as a standalone element: it must be developed based on line configuration, product flow, production targets, space constraints, and real operating conditions.

With M.H. Material Handling, this evaluation is carried out through a structured approach. Thanks to the M.H. Solution Scan, we analyze your packaging line in detail to identify critical areas and determine if, where, and how an accumulation system can improve operational continuity, reduce downtime impact, and increase real process efficiency.

When it comes to “Hygienic Design”, many people immediately think of stainless-steel equipment, free of gaps and easy to wash down.
This is a correct image — but only a partial one.

The reality is that Hygienic Design does not start — and does not end — with the equipment.
It is a structured approach that takes shape much earlier, beginning with how the facility is conceived, built, and organized.

Only by considering the entire production ecosystem — from building structures and material flows to raw material handling and personnel procedures — can safety, efficiency, and sustainability be truly ensured.
Machines come later: their role is to protect and preserve what has been designed upstream, not to compensate for shortcomings at earlier stages.

The facility as the first link in the chain

Every Hygienic Design project therefore starts with the building layout.

Its location in relation to the external environment, the distance from potential sources of contamination, floor slopes designed to promote proper drainage, and thermal insulation all directly affect the ability to maintain hygienic conditions.

Selections of materials is equally critical: walls and surfaces must be easy to clean and durable over time

If a facility is not designed with these principles in mind from the outset, the cost will be significant: more washdowns, higher water and chemical consumption, and increased operating costs.

This is not a problem that can be solved with a high-quality machine alone, but with couscous design decisions made from the very beginning.

People, raw materials, and products: the flows that make the difference

The second level focuses on internal movements.

Ingredients, semi-finished products, and personnel must not share high-risk pathways. Any overlap increases the likelihood of cross-contamination.

For this reason, more advanced manufacturers implement a hygienic segregation of production areas, physically separating high-risk zones from low-risk ones and enforcing strict procedures: garment changes, controlled access points, and physical barriers. This approach, commonly referred to as hygienic zoning, is one of the most effective tools for reducing contamination risks within food processing facilities.

Machines are the protagonists, but procedures are the script

Only at this stage does the focus shift to machinery. Their role is not to “create hygiene,” but to preserve the hygienic conditions established upstream.

Features such as cleanable surfaces, open-frame designs, tool-free removable components, and food-grade certified materials are not optional details — they are essential requirements. A single poorly designed critical point is enough to turn a machine into a source of risk.

The cost of a mistake can be substantial: Commercial Food Sanitation estimates that a product recall caused by contamination costs, on average, €1.67 million in operational losses and reputational damage.

This is why Hygienic Design is not a technical detail, but a strategic investment.

We don’t sell machines — we design safety

At MH Material Handling, we believe that Hygienic Design is not something to be applied downstream, but a philosophy that must guide every decision throughout the entire process. This is why, although we specialize in the design of conveyor systems such as Saniflex, we do not limit ourselves to supplying a machine.

Our consulting approach always starts with a comprehensive analysis of the plant: we assess layout, material and personnel flows, sanitation practices, and production requirements in order to integrate the conveying solution into a context that is truly coherent, safe, and efficient.

Saniflex is not an off-the-shelf product, but a modular and customizable system, engineered to simplify cleaning, withstand aggressive detergents, and ensure operational continuity.

What truly makes it effective, however, is its ability to fit into a broader approach in which every design choice contributes to reducing risks, costs, and operational complexity.

Would you like to understand whether your line truly complies with Hygienic Design principles — and how Saniflex can enhance it to the fullest?

It already works well as it is… do we really need to change?

This is the question many plant managers ask themselves when they look at their packaging line.

If the machines are running, orders are being fulfilled, and production continues, why intervene in something that appears to be working?

The truth is that “working” does not always mean “working at its best.”

A small bottleneck, an unexpected buildup, one manual step too many: details that often go unnoticed, yet over time erode productivity, margins, and delivery reliability.

Today, the efficiency of a line is not determined by the power of individual machines, but by the ability to integrate and harmonize every component into a balanced, seamless flow.

Conveyors: the circulatory system of the line

Just as blood carries oxygen through the body, conveyors represent the circulatory system of a packaging line.

They are responsible for synchronizing machinery, absorbing fluctuations, and preventing bottlenecks.

If the flow is not continuous and well balanced, even the most advanced machine loses its effectiveness and the risk of downtime increases.

Yet these systems are often underestimated already at the design stage, resulting in inefficiencies that are difficult to correct later on.

Different solutions for different needs

At M.H. Material Handling, we know that no two lines are the same. That is why our solutions are designed to adapt to very different products, spaces, and processes.

Heliflex LIFO Spiral System

Ideal for large product accumulation with heights not exceeding 90 mm. This double-spiral system finds its optimal sizing with between 200 and 500 meters of available space.

BAT-Buffer Modular System

Modular and compact, it is perfect for handling different product types and plant layouts. It is versatile, easy to integrate into existing lines, and has relatively limited footprint requirements. Its ideal size ranges between 100 and 150 meters of available space.

5L FIFO Multilayer Belt

Developed specifically for the confectionery sector, it enables gentle multilane transport upstream of the packaging stations, reducing the risk of product damage.

These solutions are complemented by mergers, dividers, elevators, and intelligent handling units, all designed to ensure increasingly smooth and fully integrated material flows.

Efficiency is much more than speed

Being efficient today does not simply mean “running faster.”

It means designing ergonomic lines that are easy to clean, hygienic, and capable of making the most of the available space.

It means having systems that reduce downtime, optimize energy consumption, and ensure a long-term return on investment.

Our solutions, entirely made in Italy, reflect these values: they are reliable, customized, and built to last.

With nearly forty years of experience in the food and pharma sectors, at M.H. Material Handling we do more than supply individual components.

We always start with layout consulting, analyze material flows, and develop integrated conveying and buffering solutions that transform plants into efficient and competitive ecosystems.

Our goal is simple: to help companies increase productivity and stability while reducing complexity and hidden costs.

If your line “already works well,” ask yourself: is it really expressing its full potential?

A custom-designed conveying system can make the difference between a line that merely runs and one that grows.

In the packaging industry, where every interruption can result in productivity loss, accumulation systems become strategic components to maintain performance and output. One ideal solution is the BAT Buffer by M.H. Material Handling, which we explore below.

The Heart That Keeps Your Line Alive

The BAT Buffer operates using a LIFO (Last In, First Out) logic and is designed to manage micro-stoppages typical in packaging lines. In the event of a downstream stop, the system automatically diverts incoming products to the accumulation buffer, keeping upstream machines running.

The BAT Buffer features a spiral structure that alternates straight and curved sections. This design maximizes available space, offering up to 150 meters of accumulation capacity with a single motor. The straight sections range from 2.5 to 6 meters, while the curves have an average radius of 200 mm, allowing adaptation to complex layouts.

Precision Control, Down to the Millimeter

During loading, products are guided into the buffer with a consistent pitch, regulated via inverter, preventing overlaps or damage—crucial for delicate or pressure-sensitive packaged goods.

Once normal operations resume, the BAT Buffer reverses direction and gradually releases the products back into the production flow. This can be done via an orthogonal transfer unit (to maintain product orientation) or a dynamic combiner for high-speed lines.

The average emptying time, from a full configuration, ranges from 15 to 25 minutes depending on installed capacity and downstream speed.

Recover What You Thought Was Lost

One of the BAT Buffer’s standout features is its ability to recover production lost to micro-stoppages. If downstream machines have an extra 10-20% capacity, the system can completely eliminate these losses by the end of a shift.

Its mechanical structure also enables quick switching between loading and unloading phases without needing full accumulation, helping to regularize the production flow. This operational flexibility makes it ideal for lines subject to frequent format changes or sudden production peaks.

Engineered to Fit, Wherever Needed

The BAT Buffer is ideal in sectors where output sequencing is not critical:

• Bakery and confectionery products
• Coffee and vacuum-packed goods
• Other long shelf-life items

The structure is available in anodized aluminum for standard applications or AISI 304 stainless steel for environments requiring higher hygiene standards, such as cleanrooms. It supports occasional washing without compromising performance.

Its pressure-free design and modular components make it suitable for integration into existing plants, facilitating revamping operations.
