METHOD FOR PRODUCING GAS BARRIER LAMINATE

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a gas barrier laminate by which the formation of a printing layer necessary as a packaging material and formation of a gas barrier coat layer can continuously be produced using a gravure printing method with excellent production efficiency. SOLUTION: This method for producing the gas barrier laminate is characterized by coating and forming a gas barrier coat layer prepared by coating at least one surface of a plastic substrate with an aqueous solution or a water/ alcohol mixed solution containing a water-soluble polymer and at least one of (a) one or more kinds of metal alkoxides and hydrolyzates thereof or (b) tin chloride by the gravure printing method.
