CA 2052321

A foil for use in connection with the wrapping of foodstuffs, cosmetics and other products has a plastic substrate one side of which is coated with a film of metallic material, such as aluminum. The exposed surface of the metallic film is provided with a thin protective layer which contains a wax, a resin, a lubricant and/or another organic material and shields the metallic film from scuffing, corrosion as well as from direct exposure to air and/or moisture. The metallic material of the film is vaporized onto the one side of the substrate, and the organic material of the protective layer is vaporized onto the exposed surface of the film in one or more stages as soon as the vaporization of metallic material upon an increment of the substrate is completed.
