ABSTRACT:
A multilayer film includes a first layer comprising an amorphous polymer that exhibits a glass transition temperature, and a second layer forming an exterior layer of the multilayer film and comprising a sealant material capable of forming a heat-seal, the sealant material comprising a polymer that exhibits a melting point. The glass transition temperature of the amorphous polymer is greater than the melting point of the sealant material by at least about 45 degrees centigrade.
