Polyethylene blends

A composition of matter comprising:

• (a) 30 to 70 weight percent of a low molecular weight ethylene homopolymer resin, where said resin is made by polymerizing ethylene with a chromium oxide based catalyst system, and where said resin has a density greater than 0.96 grams per cubic centimeter, a melt index greater than 30 grams per 10 minutes, a heterogeneity index from 2 to 35, and a high load melt index/melt index ratio less than 40,
• (b) 30 to 70 weight percent of a high molecular weight ethylene copolymer resin, where said resin is made by copolymerizing ethylene and an alpha-olefin with a titanium chloride based catalyst system, and where said resin has a density less than 0.955 grams per cubic centimeter, a high load melt index from 0.1 to 50 grams per 10 minutes, and a heterogeneity index from 2 to 10,
• where said weight percents are based on the total weight of said resins (a) and (b);
• and
• wherein said composition of matter has a melt index greater than 0.05 grams per 10 minutes and is essentially free of other ethylene polymers.
