PROBLEM TO BE SOLVED: To provide a laminated material which is biodegradable, has excellent oxygen barrier properties and water vapor barrier properties, has a stable vapor deposition layer, and can be used as a food packaging material. SOLUTION: A paper base layer (A), a base layer (B) composed of a biodegradable polymer laminated on the paper base layer (A), and a paper base layer (B) of the base layer (B) The oxygen transmission rate is 200 mL / m 2 / day or less and the water vapor transmission rate is 200 when the thickness of the dried film is 10 μm, which is formed on a surface different from the lamination surface of A). g / m 2 / day or less, and an anchor coat layer (C) having a moisture absorption of less than 1%, and a vapor deposition layer (D) formed on the anchor coat layer (C), -A laminated material having gas barrier properties and environmental compatibility. |
