Breathable abuse resistant film for packaging cheese
Abstract
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.
