Heat sealable blend of polypropylene terpolymers and linear low density polyethylene

摘要

A polymer blend which is useful for forming heat sealable plastic film which comprises from about 60% to about 40% by weight of a polypropylene terpolymer comprising about 0.1 to about 10.0 mole percent ethylene, about 0.1 to 10.0 mole percent 1-butene, and the balance propylene, and 40% to 60% of a copolymer of ethylene and alpha olefins containing four or more carbon atoms wherein the ethylene content has from about 90.0 to about 99.9 mole percent.
