Abstract
High density polyethylene film of improved clarity and stiffness is disclosed. The improved high density polyethylene film may be manufactured from a blend of polymers comprising an ethylene polymer of density in the range about 0.950-0.965 and of melt index less than about 10, and not more than about 30% of an ethylene polymer of melt inex in the range of about 0.1 to about 10 and of density in the range about 0.910-0.945.
