Puncture resistant, high shrinkfilms, blends, and process

摘要

A polymer blend and mono-and multilayer films made therefrom having an improved combination of properties such as high shrinkage values and high puncture resistance wherein the blend has a first copolymer of ethylene and octene-1 having a copolymer melting point of from 55 to 95 DEG C, preferably of from 80 to 92 DEG C; a second copolymer of ethylene and at least one alpha -olefin having a copolymer melting point of from 115 to 128 DEG C: and a third copolymer of ethylene and a vinyl ester or alkyl acrylate and having a melting point of from 60 to 110 DEG C, and a process for making such films, which preferably have at least 45% shrinkage at 90 DEG C in at least one direction.
