Film Extrusion Materials for High-Performance Packaging

Choosing materials for multilayer food packaging requires balancing several performance factors. Mechanical properties, barrier behaviour, processability, and forming capability all influence the overall functionality of the packaging structure.

PE, PA6/6.6, and EVOH offer different combinations of tensile strength, elongation at break, stiffness, puncture resistance, oxygen barrier, water vapour barrier, thermoformability, and processing behaviour.

The different performance profiles of these materials support the development of multilayer packaging structures tailored to specific processing and product protection requirements.

Together, these polymers fulfil complementary functions within multilayer films, helping engineers select suitable material combinations according to specific application requirements.
