Laminating Film and Laminate
Published March 30, 2004
A patent has been issued for a laminate film made up of an adhesive layer composed of an adhesive agent. The first resin layer is composed of a polypropylene resin and the first resin layer is formed above the adhesive layer. A second resin layer is formed between the first resin layer and the adhesive layer. The second resin layer contains a propylene-a-olefin copolymer as a main component, and the second resin layer is at least 0.5 times thicker than the first resin layer. The second resin layer has a Vicat softening point lower than that of the first resin layer, and the second resin layer has a melting point lower than that of the first resin layer by 2°C or more. Zinc oxide fine particles are in at least one of the adhesive layers, the first resin layer, and the second resin layer.
