Patent number: 9605122Abstract: Provided is a gas-barrier multilayer film which decreases little in gas-barrier properties even through retortion and which suffers no delamination. The gas-barrier multilayer film is characterized by comprising a plastic film and, superposed directly or through other layer on at least one surface thereof in the following order, an inorganic thin film layer and a gas-barrier resin composition layer. The gas-barrier film is further characterized in that the gas-barrier resin composition layer has been formed from a gas-barrier resin composition comprising a gas-barrier resin constituted of an ethylene/vinyl alcohol copolymer, an inorganic lamellar compound, and an additive, that the content of the inorganic lamellar compound in the gas-barrier resin composition is 0.1-9.0 mass %, that the additive is a coupling agent and/or a crosslinking agent, and that the gas-barrier resin composition layer has a thickness of 0.05-0.5 ?m.Type: GrantFiled: July 27, 2010Date of Patent: March 28, 2017Assignee: Toyo Boseki Kabushiki KaishaInventors: Youji Takatsu, Yumi Tsumagari, Takeshi Ookawa, Yoshiharu Morihara, Syuusei Matsuda

Patent number: 5856017Abstract: The present invention provides a gas barrier film including a plastic film and a thin film which is made of a composition containing an oxide as a main component and is formed on at least one surface of the plastic film. A specific gravity of the thin film is 55% or more and 100% or less of a specific gravity of the oxide in the form of a crystal generally present at room temperature and under atmospheric pressure. Thus, the invention provides a gas barrier film having an excellent gas barrier and retort properties and bending resistance; a gas barrier film suitably used in a wrapping material for dried food, liquid food or food containing liquids, frozen food and retort food; a gas barrier film that can be used in an electronic oven, can be sterilized by micro waves and can contain a free-oxygen absorber; a gas barrier film suitably used in a paper carton, a tube, a lid and the like; and a gas barrier film suitably used for cutting off gas for industrial use.Type: GrantFiled: July 18, 1997Date of Patent: January 5, 1999Assignee: Toyo Boseki Kabushiki KaishaInventors: Shusei Matsuda, Kiyoshi Iseki, Yoshiharu Morihara, Toru Kotani, Toshiyuki Oya, Toshio Uno, Teizo Harima, Hideomi Kobe, Yozo Yamada
