  • Rolling of metallic foil and plastics resin film laminates
    Patent number: 4735669
    Abstract: A method is disclosed for forming laminates of plastics resin films and metallic foils. The plastics resin film is adhesively bonded to the metallic foil. The bonded laminate is then rolled under pressure to thin both the plastics resin film and metallic foil layers. In addition to reducing the thickness of the laminate, the rolling operation increases the length of the laminate and orients the plastics resin film in the machine direction.
