THERMOFORMABLE MULTI-LAYER COMPOSITE WITH OXYGEN BARRIER AND PROTEIN-CONTAINING FORMULATION FOR PRODUCING THE MULTI-LAYER COMPOSITE

摘要

The present invention relates to a thermoformable multi-layer composite comprising at least one thermoplastic polymer layer on which a closed layer of a protein-containing formulation is deposited. The protein-containing formulation layer contains proteins that are at least partially denatured, at least one denaturing reagent, and one or more plasticizers. The multi-layer composite is permanently thermoformable and has a high oxygen barrier, so that it can be used advantageously for packaging applications in food technology.
