Patent ID: 7135526

Claim:
A polymer blend composition comprising: (a) a metallocene-catalyzed linear very low density polyethylene polymer having: (i) a density of 0.890 to 0.915 g/cm 3 , (ii) a composition distribution breadth index of 50 to 85%, (iii) a molecular weight distribution Mw/Mn of 2.0 to 3.0, (iv) a molecular weight distribution Mz/Mw of less than 2.0, and (v) two peaks in a TREF measurement; and (b) a high density polyethylene polymer having a density greater than 0.940 g/cm 3 , wherein the blend comprises 60% to 95% of the very low density polyethylene polymer and 40% to 5% of the high density polyethylene polymer, based on the total combined weight of the high density polyethylene polymer and the very low density polyethylene polymer.
