ABSTRACT:
A film includes first and second outer layers, a core layer, and first and second substrate layers, each layer including a polymer; at least one of the substrate layers includes an amidic wax, and at least one of the outer layers includes an amidic wax present in an amount of 1% to 50% of the amount of wax in the first and second substrate layers respectively. The wax can be blended with a transition metal salt of stearic acid, or ester of stearic acid. Alternatively, a film includes first and second outer layers, and a substrate layer, each layer including a polymer; at least one of the first outer layer, second outer layer, and substrate layer including a blend of an amidic wax, and a transition metal salt of stearic acid, or ester of stearic acid.
