Verwendung eines atmungsfähigen und verschleissbeständigen Films zur Verpackung von Käse

摘要

A polymeric film is proviced which comprises a core layer of polyamide and two outer layers of ethylene propylene copolymer, polypropylene, or blends thereof. Coextruded embodiments include intermediate adhesive layers. A preferred embodiment of the multilayer film exhibits a combination of good abuse resistance and oxygen barrier properties, as well as excellent optical properties and shrink properties. The differential in CO2 transmission and O2 transmission rates makes these films especially useful in cheese packaging applications.
