  • Patent number: 4223074
    Abstract: A process for the production of a laminate which comprises laminating a boehmite- or pseudoboehmite-treated aluminum foil with an oxidation-treated polyolefin film with the treated surface of the foil facing to the treated surface of the film under heat and pressure without the use of binders for lamination. In one embodiment, the laminate so produced may be laminated with the same laminate with the treated surface of the foil of the former facing to the treated surface of the film of the latter, under heat and pressure, or it may be laminated on the aluminum foil side with a resin film, such as a polyester or polyamide film, with the use of a binder between the aluminum foil and the resin film.
