  • Packing material for corrosible metallic objects
    Patent number: 8461063
    Abstract: The invention relates to a packaging material for corrosible metallic objects, comprised of a plastic film forming a package outer surface, an inner layer, and an adhesive layer bonding the plastic film to the inner layer, wherein the adhesive layer comprises a volatile corrosion inhibitor and the inner layer has a high permeability for the corrosion inhibitor on the package outer surface as compared to the plastic film. According to the invention the adhesive layer is formed by a chemically binding reaction adhesive.

  • Method for producing a laminate material web having elastic and non-elastic regions
    Patent number: 7704901
    Abstract: A method for producing an elastic laminate material web that has elastic and non-elastic regions and has non-woven fabric on both surfaces of the web. In between the two surfaces, there are film strips of an elastic film. One surface of the web consists of a planar non-woven fabric layer and is connected with non-woven fabric that is disposed on the opposite surface of the web in areas between the film strips. Each film strip is connected with a non-woven fabric layer to form a laminate strip. The laminate strips are glued to the planar non-woven fabric layer on their film side, and the non-woven fabric that is connected with the planar non-woven fabric layer between the laminate strips is in the form of non-woven fabric strips that run parallel to the laminate strips. The non-woven fabric strips overlap the non-woven fabric layer of the laminate strips in edge regions of the laminate strips.
