A polymeric film comprises a core layer of ethylene-vinyl alcohol copolymer, and two outer layers of ethylene propylene terpolymer. The outer layers are preferably blended with polypropylene. A preferred embodiment of the multilayer film, if coextruded, also includes intermediate polymeric adhesive layers. This film exhibits excellent optical properties and shrink properties while providing high oxygen barrier and is especially useful in food packaging applications. |
