Abstract: Cast films formed from polyethylene are provided that can have desirable properties. In one aspect, a cast film comprises a layer formed from a composition comprising a first composition, wherein the first composition comprises at least one ethylene-based polymer and wherein the first composition comprises 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).
