<p>PROBLEM TO BE SOLVED: To realize a transparent gas barrier laminate film capable of securing sufficient durability and gas barrier properties and having an excellent water vapor barrier property and durability.SOLUTION: In a gas barrier laminate film, an anchor layer, a gas barrier layer and an overcoat layer are sequentially formed on one surface of a substrate layer composed of a plastic film. The linear expansion coefficientαof the anchor layer at 0°C-90°C is 20 ppm/°C≤α≤200 ppm/°C. The linear expansion coefficientαof the overcoat layer at 0°C-90°C is 20 ppm/°C≤α≤200 ppm/°C.</p> |
