[ENG] From Weight to Shelf Life: The New Frontier of Fresh Produce Packaging

In the fresh produce sector, a significant part of the value generated in the field can be lost during the stages that follow harvesting.

A fruit may be perfectly developed, harvested at the right time and have excellent quality characteristics, yet reach the market with lower quality because of handling, impacts, unsuitable packaging or inadequate cold-chain management.

For this reason, talking about packaging today no longer simply means discussing how to place a product inside a container.

It means talking about how to protect the value of the product throughout the supply chain.

This distinction is particularly important for delicate, high-value produce such as berries, cherries, apricots, peaches, pears and other fruits that can quickly be affected by mechanical stress.

In this context, automation and precision can become practical tools for reducing losses and improving efficiency.

The real cost of a few extra grams

When discussing packaging precision, the first element that naturally comes to mind is weight.

But behind a few extra grams per package lies a potentially significant economic phenomenon: giveaway.

If a package is supposed to contain 125 grams of fruit, but the system consistently adds a few extra grams to avoid the risk of being underweight, that apparently insignificant quantity is multiplied across hundreds or thousands of packages.

At the end of the season, the result can represent a considerable amount of product given away without being properly valued.

Accurate weighing therefore makes it possible to work closer to the nominal weight, reducing this unnecessary loss.

This is particularly relevant for berries, where the value of the product per unit of weight can be high.

Precision does not simply mean speed

Automation in the fresh produce sector has long been associated primarily with increasing productivity.

Today, the perspective is broader.

An automated line needs to combine at least four elements:

precision, speed, gentleness and process consistency.

Increasing the number of packages produced per minute is not enough if, at the same time, the risk of damaging the product increases.

This becomes particularly evident when handling fruit harvested at an advanced stage of ripeness.

In these situations, the quality of handling can directly influence product shelf life.

Gentle handling is part of quality

Delicate fruit cannot be handled like an industrial product.

Impacts, drops, compression and poorly designed transfer points can cause micro-damage that is not always immediately visible.

The problem is that mechanical damage can become apparent later, during storage or transportation, reducing shelf life and increasing the risk of waste.

Zetapack has built an important part of its design philosophy around gentle product handling.

Its solutions have been developed to work with particularly sensitive products while maintaining a handling approach designed to protect the fruit as much as possible.

From packaging to shelf life

Shelf life is not determined when the product reaches the retail shelf.

It is the result of everything that has happened during the previous stages.

Harvesting, pre-cooling, sorting, handling, packaging, storage and transportation are all interconnected.

An efficient packaging technology must therefore be integrated into a coherent post-harvest chain.

This is particularly important for berries.

Blueberries, strawberries and raspberries can have excellent characteristics at harvest, but they require extremely careful handling to reach consumers while maintaining firmness, appearance and commercial quality.

Automation cannot solve every post-harvest challenge on its own.

However, it can help reduce one of the main sources of variability: product handling during processing and packaging.

Standardization means protecting quality

Another important advantage of automation is repeatability.

A manual process can depend on operator experience, working speed, fatigue and operating conditions.

Automation, on the other hand, makes it possible to define repeatable parameters and procedures.

This does not mean eliminating human work.

On the contrary, people and technology can be placed in a position to perform the activities where each is most effective.

Zetapack has also developed this approach in its grading systems, where automated technology can handle sorting according to defined parameters while operators retain an important role in product management.

Less product waste means greater sustainability

When sustainability in packaging is discussed, attention is often focused exclusively on the materials used for packaging.

This is certainly an important aspect.

But supply-chain sustainability must also consider how much of the product is actually delivered to consumers and valued.

If producing one kilogram of fruit requires water, energy, fertilizers, labor, agricultural land and logistics resources, losing part of that production also means losing all the resources invested in producing it.

Reducing post-harvest waste therefore means improving the overall efficiency of the system.

This is one of the reasons why weighing accuracy, gentle handling and process optimization can be considered sustainability tools as well as efficiency tools.

Packaging is changing too

Alongside the search for greater efficiency, the sector is also undergoing a transformation in packaging materials.

Companies increasingly need to handle different formats and, in many cases, alternatives to traditional plastic packaging.

This requires flexible machinery.

A modern packaging line cannot be designed exclusively around today's packaging format. It must be capable of adapting to future market developments.

Zetapack has developed its solutions with a focus on flexibility, allowing different packaging formats to be handled.

The MP4, for example, can handle different types of punnets with indicative weights ranging from 125 to 1,000 grams.

This adaptability is becoming increasingly important in a market where packaging formats, materials and retail requirements can change rapidly.

Automation must be adapted to the company

Another important aspect is technology accessibility.

Automation does not necessarily mean installing a huge, fully automated line.

For many farms and small and medium-sized operators in the supply chain, the transition toward automation can be gradual.

This is one of the aspects considered in the development of Zetapack's MP4: a compact solution designed also for companies that want to begin automating weighing and packaging without requiring large warehouse spaces.

The machine measures approximately 3,900 × 2,600 mm and can reach around 40 packages per minute while maintaining high weighing accuracy.

The possibility of introducing automation progressively can therefore represent an important factor in the competitiveness of smaller operations.

The future is an increasingly measurable process

One of the most interesting developments in automation does not concern machines alone.

It concerns data.

A modern packaging line can generate information about quantities processed, weights, productivity and process performance.

This data can become a management tool.

Companies can identify where the greatest inefficiencies occur, which packaging formats require more time, how much product is used on average for each package and where there is room for improvement.

Technology therefore evolves from being simply an operational tool into a process-control tool.

From harvest to consumer: one supply chain

The quality of a fresh produce package does not depend only on what happens in the packing house.

It depends on a supply chain in which every stage must be consistent with the next.

Harvesting too early, inadequate temperature management or aggressive handling can compromise the final result even when excellent packaging is used.

For this reason, the future of post-harvest management will increasingly rely on the integration of:

• harvesting management;

• cooling;

• sorting;

• weighing;

• packaging;

• quality control;

• logistics;

• shelf-life monitoring.

Within this system, the machine is not an isolated element.

It is part of a process.

Zetapack: When Precision and Gentle Handling Become Value

The experience of Zetapack in machinery for fresh produce processing and packaging demonstrates how automation and respect for the product can work together.

From grading systems to weighing machines and solutions dedicated to berries, the objective is to find the right balance between productivity, precision and gentle handling.

The challenge is not simply to package faster.

It is to package better, reducing product waste, minimizing giveaway, standardizing the process and helping preserve fruit quality all the way to the consumer.

In a sector where every gram and every additional day of shelf life can have significant economic value, packaging precision therefore becomes an integral part of the production strategy.

And when technology is designed around the characteristics of the product, it can evolve from a simple investment into a practical tool for improving the efficiency and sustainability of the entire supply chain.
