Patent ID: 7247680

Claim:
A polyethylene composition comprising a homogenous blend of a low density polyethylene with a metallocene-catalyzed polyethylene having a density of at least 0.906 g/cm 3 and a Dow Rheology Index of at least 5/MI 2 , wherein MI 2 is the melt index measured according to ASTMD-1238 condition 190° C./2.16 kg and the Dow Rheology Index being determined by a dynamic rheological analysis performed at 190°, said metallocene-catalyzed polyethylene being catalyzed with a catalyst system comprising a metallocene component and an activating agent selected from the group consisting of an alumoxane or an aluminum alkyl providing a mole ratio of aluminum to the transition metal of said metallocene component within the range of 50:1-300:1.
