Abstract

The invention provides cross-linked polymeric films, laminates, membranes or other polymeric articles, which show rubber like heat resistance (hot set) and dimensional stability above the polymer melting point, while maintaining heat sealing properties. For example, the invention provides a film comprising at least one layer formed from a composition comprising the following components: A) at least one polymer selected from the group consisting of the following: i) an ethylene-based polymer, ii) an ethylene/α-olefin/diene interpolymer, and ii) a C4-C10 olefin-based polymer; B) at least one polymer selected from the group consisting of a propylene/ethylene interpolymer and a propylene/&alpha,- -olefin interpolymer; and wherein the film is crosslinked using radiation and/or chemicals.
