BLENDS OF LOW DENSITY POLYETHYLENE AND BUTENE/ETHYLENE COPOLYMERS AND HIGH TEAR STRENGTH BLOWN FILM MADE THEREFROM

摘要

By incorporating low density polyethylene (e.g., above 5 to about 15 weight percent) into a butene-1/ethylene copolymer containing from about 0.25 to about 3 mole percent ethylene, a resin blend is provided that is extrudable at substantially high extrusion rates to a blown tubular film of substantially high tear strength.
