Abstract

A polymer composition that can be used to form a melt-extruded film is provided. The polymer composition may contain an olefinic polymer and a transition metal salt. By selectively controlling specific aspects of the polymer and the transition metal salt, as well as the relative concentration of each component, the present inventors have discovered that the resulting composition can exhibit a relatively fast oxidation rate, which has been found to improve the adhesion of the composition to a wide variety of substrates.
