Multilayer packaging materials: modalities of choice and applications

In the world of food packaging, there is a family of flexible packaging known as "multilayer packaging". They have been developed to optimize the packaging functions of a food product (product preservation over time, visual marketing, environmental protection, special functionalities, etc.). Food consumers are increasingly demanding. They want, for example, easy-open packaging, resealable packaging, and packaging with a long shelf life.

The "product preservation" issue has also contributed to the development of multilayer packaging. Soft cheese cannot be packaged in the same flexible multilayer packaging as freeze-dried coffee. These products have totally different needs in terms of post-packaging preservation. This determines the choice of packaging materials.
