PROBLEM TO BE SOLVED: To provide a laminate which has excellent bending resistance, heat resistance, dimensional stability and light shielding properties, has a good gas barrier property against oxygen, odor and water vapor, and is easy to dispose of. To provide. SOLUTION: A layer A of a vinyl alcohol polymer having an ethylene content of 0 to 15 mol% is laminated on a substrate B of paper or a biaxially stretched film to form a barrier layer 2 composed of the substrate B and the layer A. Then, the coating layer 1, the barrier layer 2, and the paper substrate 3 are laminated. |
