Abstract
Abstract Reflective surfaces are imparted to molded objects by use of improved foils. A preferred structure comprises a substrate, a metal layer, and a protective film or coating over the metal layer. The substrate layer is preferably a film of material which is identical with or compatible to the substance used to mold the article or ware. The protective film is preferably a heat and scuff resistant material such as a 25 to 150 gauge polyester film. The metal layer, or metal surface is preferably a vacuum metallized surface and may be deposited either upon the substrate film or upon the protective film.
