(57) [Summary] [PROBLEMS] To provide excellent strength, rigidity, etc., and to provide impact resistance, heat resistance, pressure resistance, water resistance, heat sealability, pinhole resistance, piercing resistance, and fragrance retention. Excellent physical properties and other physical properties, Furthermore, it is excellent in barrier properties to prevent the permeation of oxygen gas, water vapor, etc., and also aims to reduce the production cost by reducing the production process while reducing the amount of containers and packaging waste. It is useful for filling and packaging various goods such as pharmaceuticals, reagents, chemicals, cosmetics, sundries, etc., and has excellent filling and packaging suitability for its contents, storage suitability, etc. In particular, it is to provide a self-supporting bag useful as a container for refilling shampoos, rinses, detergents and the like. SOLUTION: At least a base film, a barrier base material provided with an inorganic oxide deposition film and a gas barrier coating film on one surface of a resin film, and a heat-sealing resin layer are sequentially formed. The present invention relates to a self-supporting bag characterized in that the bag is made from a laminated material laminated on the bag. |
