Patent ID: 8829137

Claim:
A film comprising a copolymer of ethylene and 1-hexene wherein the film has a haze of ≦12%, a dart impact of ≧500 g/mil, an MD tear of ≧200 g/mil and wherein the copolymer has a density of from 0.916 g/cc to 0.930 g/cc, a melt index (I 2 ) of from 0.3 to 3 g/10 min, a melt flow ratio (I 21 /I 2 )<20, a molecular weight distribution (M w /M n )≦2.5, and satisfies the condition: CDBI≦(β+25)/a-parameter; where β is the amount in weight % of the copolymer that elutes at 90° C. and above as determined by TREF, CDBI is the comonomer distribution breadth index determined by TREF, and the a-parameter is the Carreau-Yasuda shear exponent as determined by DMA at 190° C.
