Food preservation packaging: technologies and applications

Maintaining the freshness of food, preserving its organoleptic characteristics and ensuring high safety standards are fundamental objectives for every company in the food sector. Packaging plays a key role in this process, becoming a strategic element for the conservation and distribution of food products.

Thanks to the evolution of packaging materials and technologies, it’s now possible to extend food shelf life, reduce waste, and improve consumer-perceived quality. For this reason, choosing the right food preservation packaging represents a significant investment for producers, delicatessens, laboratories, and large-scale retail companies.

The importance of packaging in food preservation

Every food is subject to natural processes of deterioration caused by factors such as oxygen, humidity, light and microbiological contamination. Proper packaging allows you to create a protective barrier that limits these phenomena and helps keep the product in the best possible condition.

A correct packaging solution allows you to:

• preserve freshness and flavor;
• maintain consistency and visual quality;
• reduce the risk of contamination;
• facilitate transport and storage;
• increase the commercial life of the product.

The choice of the most suitable technology depends on the type of food and the required conservation objectives.

Thermosealing: safety and versatility

Among the most common technologies in the food sector is thermosealing, a system that involves sealing a tray using a protective film applied with heat and pressure.

This solution offers numerous advantages:

• airtight and safe closure;
• protection from external contamination;
• excellent product presentation;
• compatibility with different materials and formats.

Heat-sealable trays are used for fresh pasta, delicatessen, ready-to-eat meals, over-the-counter products, and large-scale distribution.

Modified atmosphere for a longer shelf life

When storage needs to be extended further, the modified atmosphere (ATM or MAP) is used. This technology replaces the air in the package with a controlled mixture of food gases.

Using the modified atmosphere allows you to:

• slow down bacterial activity;
• limit oxidation processes;
• maintain color and freshness;
• reduce food waste.

It’s a particularly popular solution for meat, fish, cheeses, fresh pasta and gastronomic products.

Vacuum packaging: maximum protection

Vacuum packaging almost completely removes air from the package before closing. This technique reduces the presence of oxygen and helps slow the deterioration of the food.

The main advantages are:

• longer product life;
• high hygienic protection;
• logistics optimization;
• reduction of waste.

Vacuum packaging is the ideal for cured meats, cheeses, meats and gastronomic preparations that require long storage times.

Innovative materials for high performance

Preservation technologies are only effective when combined with performative materials. Today the market offers advanced solutions such as:

• PP and PET trays;
• recyclable and recycled materials;
• multilayer structures with EVOH barrier;
• certified compostable packaging;
• high barrier films against oxygen and humidity.

These materials provide protection, food safety and compliance with european regulations.
