Abstract
A thermoplastic film having a substantially continuous, adherent coating on at least one surface, wherein the coating includes a polymeric binder and nano-scale particles. When the coating is formed on the surface of the film, the nano-scale particles form a barrier that substantially reduces the diffusion of moisture and oxygen. In preferred embodiments, the coating includes a polymeric binder and silicate particles formed on a base substrate layer that includes a polyolefin selected from the group consisting of homopolymers, copolymers, and terpolymers of propylene, ethylene, butylene, and blends thereof.
