Patent ID: 8722804

Claim:
A polymer blend, comprising: a first polyethylene having a density of less than about 0.940 g/cm 3 , a melt index (I 2 ) greater than 0.75 g/10 min, a melt index ratio (I 21 /I 2 ) of less than 30, and a molecular weight distribution (Mw/Mn) of from about 3.5 to about 5.5; and a second polyethylene having a density of less than about 0.940 g/cm, a melt index (I 2 ) of less than 1 g/10 min, a melt index ratio (I 21 /I 2 ) greater than 30, and a molecular weight distribution (Mw/Mn) of less than 4.5, M w and Mn being determined using gel permeation chromatography, density being determined in accordance with ASTM D-792, I 2 being determined using ASTM D-1238E (at 190° C., using a 2.16 kg weight) and I 21 being determined using ASTM D-1238F (at 190° C., using a 21.6 kg weight).
