Abstract

A retortable multilayer packaging film has a crosslinked first outer layer which serves as a heat seal layer/ product-contact layer. The first outer layer comprises a blend of (i) a homogeneous propylene-based polymer and (ii) a homogeneous ethylene/C4-20 alpha-olefin copolymer having a density of from about 0.86 g/cc to about 0.91 g/cc. The film also has a crosslinked second outer layer that serves as a heat seal/skin layer, and which comprises a blend of a homogeneous propylene-based polymer and a homogeneous ethylene/C4-20 alpha-olefin copolymer. The invention also pertains to packaging articles made from the film, packaged products utilizing the film in the package, and a packaging process utilizing the film
