PROBLEM TO BE SOLVED: To provide a self-supporting bag excellent in strength and rigidity, further excellent in various physical properties such as resistances to impact, heat, pressure, water, pinhole formation and piercing, heat-sealing characteristics, aroma-retaining characteristic and other properties, furthermore excellent in barrier properties of preventing permeation of oxygen gas, stem and the like, moreover capable of reducing the quantity of container and packaging refuse to be generated and reducing a manufacturing cost of the bag by shortening its manufacturing steps, useful for filling and packaging various articles, such as, for example, food and drink, drugs, reagents, chemical products, cosmetics, sundries and other goods, excellent in fillable properties and packageability for contents, shelf stability thereof and the like, and particularly useful as a refilling container for a shampoo, a rinse, a detergent and the like. SOLUTION: The self-supporting bag is manufactured from a laminated material wherein at least a base film, a barrier base material provided with a vapor-deposited film of an inorganic oxide and a gas barrier coated film on one of faces of a resin film, and a heat-sealing resin layer are laminated sequentially.
