COLD SEAL RELEASE FILM WITH IMPROVED SCUFF RESISTANCE

摘要

A cold seal release film in the form of a monolayer film or an outer layer of a multilayer film. The cold seal release film includes a nucleating agent and 10%-100% by weight of the polymer composition of a polymer selected from the group consisting of poly-1-butene homopolymers, poly-1-butene/ethylene random copolymers having over 50% by weight poly-1-butene therein and a blend of the poly-1-butene homopolymers and poly-1-butene/ethylene random copolymers, and 90%-0% by weight of the polymer composition of a polymer selected from the group consisting of ethylene random copolymers of polypropylene, butene random copolymers of polypropylene and ethylene-butene random terpolymers of polypropylene.
