ABSTRACT:
A polyethylene composition comprising: (a) about 1 to about 30 weight percent of a branched polyethylene resin, wherein said resin is produced by the high pressure, free radical, polymerization process, and wherein said resin has a density from about 0.91 to about 0.93 grams per cubic centimeter, and wherein said resin has a melt index less than 6 grams per 10 minutes; and (b) about 99 to about 70 weight percent of a linear polyethylene resin, wherein said resin is produced by the low pressure, transition metal, polymerization process, and wherein said resin has a density from about 0.91 to about 0.94 grams per cubic centimeter, and wherein said resin has a melt index less than about 1 gram per 10 minutes, and wherein said resin has a shear ratio greater than about 50, and wherein said resin has a heterogeneity index greater than 6; wherein said weight percents are based on the weight of said polyethylene composition.
