Claim:
1. A blown film comprising an ethylene polymer having a melt index less than or equal to about 0.4 g/10 min and a density in a range from about 0.913 to about 0.93 g/cm 3 , wherein the ethylene polymer comprises a higher molecular weight component and a lower molecular weight component, and wherein: a number of Long Chain Branches (LCB) of the lower molecular weight component is in a range from about 5 to about 50 LCB per million total carbon atoms; a number of Long Chain Branches (LCB) of the higher molecular weight component is less than or equal to about 5 LCB per million total carbon atoms; and the film has a dart impact strength greater than or equal to about 300 g/mil.
