Abstract
A multilayer film having enhanced toughness and optical properties is provided. The multilayer film includes a base layer, an outer layer, and a tie layer between the base layer and the outer layer. The multilayer film can also include additional layers. Methods for making such multilayer films are also provided. Multilayer films according to the present invention are particularly useful packaging applications where rupture resistance and high clarity are desirable.
