ABSTRACT:
A heat sealable blend of a butene-1-ethylene copolymer, about 2 to 9% by weight of polypropylene and from about 0.02 to 1.5% by weight of high density polyethylene can be processed at high line speed in the blown-bubble extrusion process to form films or sheets exhibiting improved heat sealing characteristics, processability, tear strength and other properties.
