SELF UNIFIED, HEAT SEALABLE, MULTILAYER FILM

摘要

A self unified, heat sealable, multildyer film comprising a polyester layer chemically interfacially bonded to a polyolefinic layer containing from about 250 to 750 parts per million of a fatty acid amide, Wherein the interfacial bond between said polyester layer and said polyolefinic layer is so strong that said layers cannot be mechanically separated.
