Abstract

A multilayer heat-shrinkable film is provided which includes at least one heat sealing layer which is a blend of a propylene copolymer and a homogeneous ethylene alpha-olefin copolymer having a density below about 0.90 g/cc. Prefera-bly, the outermost layer is compatible with the. heat sealing layer for ready formation of a lap seal for end use applica-tions such as backseamed casings. An internal polyamide-con-taining layer provides excellent elastic recovery:
