More Information
Summary:A window envelope that includes a window patch formed from a low gloss polymer film based upon a rubber-modified vinyl aromatic polymer or a blend of a rubber- modified vinyl aromatic polymer and a vinyl aromatic polymer. The film may be a monolayer film or an external layer of a multilayer film. The film optionally includes an inorganic coating applied to either surface of the film where the film is a monolayer film or to an outermost surface of the film where the film is an external layer of a multilayer film. When an inorganic coating is applied to a film surface, the film need not include a rubber- modified vinyl aromatic polymer and may be based solely upon a vinyl aromatic polymer.
