Abstract
A multi-layer film includes a base layer comprising a polyolefin and at least one additional layer comprising a metallocene-catalyzed syndiotactic polypropylene, wherein the base layer and the at least one additional layer comprising a metallocene-catalyzed syndiotactic polypropylene are not suitable for use as a heat sealable film. The multi-layer films of the present invention have improved metallizable surfaces and the metallized films exhibit excellent gas (e.g., oxygen and water vapor) barrier properties, as well as good pick off, optical properties (optical density, haze, and gloss), and coefficient of friction (COF).
