Abstract
In a gas barrier laminate film comprising a base material film containing an inorganic compound and at least one set of inorganic layer and organic layer formed on the base material film, the base material film is formed with a resin having a glass transition temperature of 25° C. or higher. A gas barrier laminate film that has superior durability, heat resistance and gas barrier performance, shows a small difference in coefficient of linear expansion relative to a contiguous layer and can maintain superior gas barrier property even if it is bent is provided.
