BARRIER LAMINATED FILM AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a barrier laminated film excellent in gas barrier properties and hot water resistance and holding excellent gas barrier properties even after boiling treatment and retorting treatment. SOLUTION: The barrier laminated film is constituted by providing a composite polymer layer at least on one side of a base material film comprising a thermoplastic resin through an inorganic thin film layer and the composite polymer layer is formed by the polycondensation of a coating composition containing an alkoxysilane or its hydrolysate, polyvinyl alcohol and/or an ethylene/vinyl alcohol copolymer.
