ABSTRACT:
A blend comprising a mixture of two ethylene/alpha-olefin copolymers, said blend having a flow index in the range of about 5 to about 50 grams per 10 minutes; a melt flow ratio in the range of about 10 to about 50; a density in the range of 0.900 to 0.940 gram per cubic centimeter; a molecular weight in the range of about 98,000 to about 190,000; and an Mw/Mn ratio in the range of about 2 to about 8, said blend having been prepared by mixing first and second copolymers having about equal molecular weights, each copolymer being a copolymer of ethylene and an alpha-olefin having 3 to 8 carbon atoms, the first copolymer having a flow index in the range of about 5 to about 75 grams per 10 minutes; a melt flow ratio in the range of about 10 to about 50; a density in the range of 0.860 to 0.930 gram per cubic centimeter; a molecular weight in the range of about 87,000 to about 190,000; and an Mw/Mn ratio in the range of about 2 to about 4 and the second copolymer having a flow index in the range of about 5 to about 75 grams per 10 minutes; a melt flow ration in the range of about 10 to about 50; a density in the range of 0.935 to 0.970 gram per cubic centimeter; a molecular weight in the range of about 87,000 to about 190,000; and an Mw/Mn ratio in the range of about 2 to about 4, the weight ratio of the first copolymer to the second copolymer being in the range of about 70:30 to about 30:70.
