RETORTABLE AND RECYCLABLE POUCH

Technology description

The Recyclable Retortable Pouch is an advanced flexible packaging solution designed to withstand the retort sterilization process, a widely used thermal preservation method that helps extend the shelf life of packaged foods.

Unlike conventional retortable laminates, this structure has been developed to support recyclability while maintaining high barrier performance, allowing brands to move toward more sustainable packaging formats.

Its multilayer construction protects the packaged product against oxygen, moisture, and light, helping preserve quality and product characteristics throughout the supply chain.

This innovation represents an important step in combining food safety, extended shelf life, and circular packaging design.

Structure and materials

The pouch is manufactured using polyethylene-based multilayer structures designed to provide mechanical strength and barrier protection.

Typical components include:

Recyclable polyethylene structural layers 
EVOH oxygen barrier layer 
Food-grade lamination adhesives
 High-definition printing through flexographic or rotogravure technologies

Key performance benefits

Designed for retort sterilization
conditions 
High resistance to oxygen
transmission 
Protection against moisture and light exposure
Mechanical stiffness comparable to PET laminates 
Structure designed for recyclability within PE recycling streams

Typical applications

Ready-to-eat meals
Sauces and dressings
Shelf-stable foods
Retort-processed packaged foods
