Materials Selection for Flexible Packaging

Multilayer flexible packaging is defined as a structure where there is a combination of two or more layers, polymerics or not, disposed in parallel one to another. This commonly presents a structure compounded by thin foils brought together that enables functional, protective and/or decorative properties. In most cases, a single polymer cannot meet all the requirements to achieve a given packaging performance. As a result, monolayer films have been replaced by multilayer films for production of flexible packaging structures.
