Abstract:

Multi-layer polymeric films having at least one skin layer comprising at least one polyhydroxyether component or a combination of at least one polyhydroxyether component and at least polyester component are provided. The multi-layer films exhibit advantages such as high surface energy contributing to improved printability, barrier properties, and metallization. Additionally, the films exhibit improved adhesion between the skin layer and other layers of multi-layer film structures. In certain embodiments, the at least one skin layer incorporates from about 70 wt. % to about 100 wt. % of the at least one polyhydroxyether component or the combination of the at least one polyhydroxyether component and the at least one polyester component. The combination of the at least one polyhydroxyether component and the at least one polyester component incorporates from about 1 wt. % to about 99. 0 wt.
