  • Foil coating process
    Patent number: 3955016
    Abstract: In a double-pass lamination and coating process, aluminum foil is laminated on one side with paper and then rolled for temporary storage before being coated on the other side with polyethylene. Contaminants from the paper impair the ability of aqueous solutions of chromium complex adhesion promoters to bond the polyethylene to the foil. A wash coat of polyvinyl alcohol before rolling eliminates this impairment.
