Abstract
A multilayer blown film having an inner layer, a first outer layer, and a second outer layer, wherein the inner layer comprises an ethylene-based polymer having a MWCDI value greater than 0.9, and a melt index ratio (I10/I2) that meets the following equation: I10/I2≥7.0−1.2×log (I2); and the first outer layer and the second outer layer independently comprise a polyethylene composition which comprises the reaction product of ethylene and, optionally, one or more alpha olefin comonomers, wherein the polyethylene composition is characterized by the following properties: (a) a melt index, I, of from 0.1 to 2.0 g/10 min; (b) a density of from 0.910 to 0.930 g/cc; (c) a melt flow ratio, I/I, of from 6.0 to 7.6; and (d) a molecular weight distribution, (Mw/Mn) of from 2.5 to 4.0.
