Abstract
A polymeric composition including a first copolymer of ethylene and a higher .alpha.-olefin having 3 to 12 carbon atoms, said first copolymer having a density of between 0.880 g/cc. and about 0.949 g/cc. and a melt index of between about 0.01 and about 100, present in the polymeric composition in a concentration of between about 60% and about 95% by weight; and a second copolymer of ethylene-vinyl acetate having a vinyl acetate content of at least about 28% by weight, based on the total weight of the ethylene-vinyl acetate copolymer, said second copolymer present in a concentration of between about 5% and about 40% by weight, said percentages by weight based on the total weight of the polymeric composition. This polymeric composition is particularly useful when fabricated into a film, which has excellent impact strength.
