TH12692A - Foil and method of foil making - Google Patents

Abstract

Foils for use in connection with food wrapping Cosmetics and other products which have a plastic base layer, one side of which is coated with a film of organic materials. For example, aluminum provides the exposed surface of the metallic film with a thin protective layer. They are made up of waxes, lubricants and / or other organic materials and will protect the metallic layer from abrasion, corrosion as well as from direct exposure to air and / or moisture. Will vaporize the organic material of the film on one side of the base layer And it will vaporize the organic material of the protective layer on the exposed surface of the film in one or more steps as soon as the organic material vaporization on the incremental part of the base layer has been completed.

Claims (4)
