Document Type and Number:
Japanese Patent JP7052205
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a gas barrier laminated film which exhibits excellent gas barrier property under a severe environment.SOLUTION: A gas barrier laminated film 10 is formed by laminating resin base materials 11 and 15, vapor-deposited layers 12 and 16 laminated on at least one surface of the resin base material and two or more gas barrier films 18 and 19 having an overcoat layer 13 laminated on the vapor-deposited layer through adhesive layers 14 and 17, where the vapor-deposited layer is a vapor-deposited film containing at least one selected from metallic silicon, silicon oxide, metallic aluminum and aluminum oxide, the overcoat layer contains a water-soluble polymer having a hydroxyl group, alkoxysilane or its hydrolysate, and oxygen permeability on measurement conditions of 30°C and 70RH after a tensile test of an elongation of 3% at 100 μm/sec is 5 times or less oxygen permeability on measurement conditions of 30°C and 70RH before a tensile test.SELECTED DRAWING: Figure 1
