ABSTRACT:
A polymer blend and mono-and multilayer films made therefrom having improved properties such as heat sealing or puncture resistance wherein the blend has a first polymer of ethylene and at least one .alpha.-olefin having a polymer melting point between 55 to 75.degree. C.; a second polymer of ethylene and at least one .alpha.-olefin having a polymer melting point between 85 to 110.degree. C. and a third thermoplastic polymer having a melting point between 115 to 130.degree. C.; and optionally a fourth polymer e.g. EVA, having a melting point between 90 to 100.degree. C.
