Abstract

A composition comprises a polyethylene of specific gravity greater than 0.935 and melt index above 0.1, with more than 30 and less than 60% of the composition of a polyethylene of specific gravity not greater than 0.922 and a melt index not greater than 2. A preferred specific gravity is between 0.935 and 0.96 and preferred melt indices are between 1 and 0.1 and between 2 and 0,07 respectively. The composition may be intimately blended together by a mastication process. Specification 790,115 is referred to.
