Abstract:
1. A packaging material for corrosible metallic objects, comprised of a plastic film forming a package outer surface, an inner textile layer, and a hardened foamed adhesive layer bonding the plastic film to the inner textile layer, wherein the hardened foamed adhesive layer is a chemically set reaction adhesive which comprises a polyurethane, water, a volatile corrosion inhibitor and on a surface of the hardened foamed adhesive layer, a plurality of small gas bubbles consisting of carbon dioxide in the micrometer to nanometer range which are created by a chemical reaction with gas formation during the hardening of the foamed adhesive, and the inner textile layer contains fibers which partially penetrate through a surface of the hardened foam adhesive layer and which has a higher permeability for the corrosion inhibitor on the package outer surface as compared to the permeability for the corrosion inhibitor for the plastic film.
