Claim:
A blown film comprising at least two skin layers and at least one core layer there between, wherein: (a) the skin layers comprise at least one linear ethylene-α-olefin copolymer having an I 21 /I 2 of greater than 20; a density within the range from 0.910 to 0.945 g/cm 3 ; an Mw/Mn within the range from 2.0 to 5.0; and at least a 5 wt % portion that is soluble at 60° C. or less in xylene, where the soluble portion has: i) an Mw (GPC) of 150,000 g/mol or more; ii) at least 5 mol % C 3 to C 20 comonomer as determined by 13 C NMR; iii) a r 1 r 2 value of 1.0 or less; and iv) a “butyls” per 1000 carbons value of 15 or more; and (b) the core layer comprises at least one polyethylene having an overall density of at least 0.910 g/cm 3 ; wherein the film has a dart impact (ASTM D1709) of greater than 10 g/μm and a Haze (ASTM D1003 method B) of less than 10%.
