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 (21.6/2.16kg, 190°C) of greater than 20; a density (ASTM D-1505 and ASTM D-4703-07) within the range from 0.910 to 0.945 g/cm 3; an Mw/Mn (determined by Gel Permeation Chromotography) within the range from 2.0 to 5.0, and a Composition Distribution Breadth Index (CDBI) of less than 40% as determined using Temperature Rising Elution Fraction (TREF); 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 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 calculated by the formula: r 1 r 2 = 4 * EE*HH EH 2 wherein EE, HH and EH are the diad concentrations of ethylene-ethylene, hexene-hexene and ethylene-hexene; iv) a "butyls" per 1000 carbons value of 15 or more, calculated by dividing the 1-hexene-centered triads by the sum of twice the ethylene-centered triads plus six times the 1-hexene-centered triads and the resultant quotient multiplying by 1000: Butyls per 1000 Carbons = HHH + HHE + EHE 6 * HHH + HHE + EHE + 2 HEH + EEH + EEE * 1000; and (b) the core layer comprises at least one polyethylene having an overall density (ASTM D1505 and ASTM D-4703-07) of at least 0.910 g/cm 3; wherein the film has a dart impact (ASTM D1709) of greater than 15 g/μm and a Haze (ASTM D1003 method B) of less than 10%. (a) the skin layers comprise at least one linear ethylene-α-olefin copolymer having an I 21 /I 2 (21.6/2.16kg, 190°C) of greater than 20; a density (ASTM D-1505 and ASTM D-4703-07) within the range from 0.910 to 0.945 g/cm 3; an Mw/Mn (determined by Gel Permeation Chromotography) within the range from 2.0 to 5.0, and a Composition Distribution Breadth Index (CDBI) of less than 40% as determined using Temperature Rising Elution Fraction (TREF); 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 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 calculated by the formula: r 1 r 2 = 4 * EE*HH EH 2 wherein EE, HH and EH are the diad concentrations of ethylene-ethylene, hexene-hexene and ethylene-hexene; iv) a "butyls" per 1000 carbons value of 15 or more, calculated by dividing the 1-hexene-centered triads by the sum of twice the ethylene-centered triads plus six times the 1-hexene-centered triads and the resultant quotient multiplying by 1000: Butyls per 1000 Carbons = HHH + HHE + EHE 6 * HHH + HHE + EHE + 2 HEH + EEH + EEE * 1000; and i) an Mw 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 calculated by the formula: r 1 r 2 = 4 * EE*HH EH 2 wherein EE, HH and EH are the diad concentrations of ethylene-ethylene, hexene-hexene and ethylene-hexene; iv) a "butyls" per 1000 carbons value of 15 or more, calculated by dividing the 1-hexene-centered triads by the sum of twice the ethylene-centered triads plus six times the 1-hexene-centered triads and the resultant quotient multiplying by 1000: Butyls per 1000 Carbons = HHH + HHE + EHE 6 * HHH + HHE + EHE + 2 HEH + EEH + EEE * 1000; and (b) the core layer comprises at least one polyethylene having an overall density (ASTM D1505 and ASTM D-4703-07) of at least 0.910 g/cm 3;
