摘要

PROBLEM TO BE SOLVED: To provide a gas-barrier film which is transparent, flexible, superior in gas-barrier properties not affected by temperature and humidity, better in recyclable properties after the film is discarded, and friendly to the environment without generation of harmful substances when the film is incinerated. SOLUTION: In a laminated material wherein an anchor coat layer 2, a deposited thin film layer 3 composed of an inorganic oxide and a gas-barrier coating layer 4 are laminated in turn at least on one face of a base material film 1 composed of a polyamide resin, a surface roughness Rz (ten points average roughness) of a laminated face side of the base material 1 is 0.25μm or less.
