Abstract: Polyolefin films having high oxygen transmission values are composed of blends of 75 to 92% isotactic polypropylene, 5 to 15% by weight low density polyethylene and 3 to 10% by weight of an olefin heteropolymer containing propylene and at least one other olefin 2 to 4 carbon atoms having a melting point less than that of polypropylene and a density ofr at least about 0.95 g/cc.
