Disclosed herein is a casting film comprising a polyethylene composition comprising the reaction product of ethylene and, optionally, one or more alpha-olefin comonomers, wherein said polyethylene composition is characterized by the following properties: a melt index, I2, measured according to ASTM D1238 (2.16 kg, 190°C), from 1 to 20 g/10 min; a density (measured according to ASTM D792) of 0.935 to 0.970 g/cm 3 ; a melt flow ratio, I10/I2, where I10 is measured in accordance with ASTM D1238 (10 kg, 190°C) of 5.5 to 7.0; a molecular weight distribution (Mw/Mn) of 2.2 to 3.5; and a vinyl unsaturation greater than 0.12 vinyl per thousand carbon atoms present in the backbone of the composition. |
