ABSTRACT:
It is disclosed a polyolefin blend having an exhibiting improved processability and mechanical properties comprising of a major amount of a high molecular weight or low melt flow polyolefin, and minor amounts of a high melt flow polyolefin and an ordinary melt flow polyolefin copolymer. The improvement in processability, optical, and mechanical properties is synergistic, and is particularly evident by the improvement in output rate and dart drop impact strength.
