Biaxially stretched, heat shrinkable polymeric film comprising three copolymers, blends and process for foods

摘要

A flexible biaxially stretched heat shrinkable polymeric film having at least one layer comprising a blend of at least three copolymers comprising: a) 20-85 weight percent polymer with a melt point of 80-98oC with one copolymer of ethylene and hexene-1; a) 5-35 weight percent of a second polymer with a melt point of 115-128oC with at least one copolymer of ethylene and one á-olefin; b) 10-50 weight percent of a third polymer with a melt point of 60-110oCwith at least one copolymer of ethylene and a vinyl ester, an alkyl acrylate, acrylic acid or metharcylic acid; wherein the first and second polymers have combined weight percentage of 50.
