GAS BARRIER LAMINATE HAVING RESISTANCE TO PINHOLE

摘要

PROBLEM TO BE SOLVED: To provide a gas barrier laminate which is free from an environmental problem relating to waste and excellent in adhesion and production efficiency, not necessitating an anchor coat processing on the occasion of laminating, and further prevents occurrence of a bending pinhole in transportation or the like in a process of distribution. SOLUTION: The gas barrier laminate is constituted by laminating a transparent gas barrier vapor deposition film having at least a vapor deposition thin film layer of an inorganic oxide formed on a corona-treated surface of a biaxially oriented polyamide film at least one side of which is subjected to the corona treatment, and a sealant film. The biaxially oriented polyamide film and the transparent gas barrier vapor deposition film are laminated by the medium of an adhesive resin being adhesive to the two base materials, having a density of 0.920 g/cm3or below and being melted and extruded.
