[PROBLEMS] To provide a retort that has excellent barrier properties to prevent permeation of oxygen gas, water vapor, etc., has contents filling and packaging suitability, storage suitability, etc., and is extremely excellent in disposal treatment suitability and environmental suitability after use. Providing a pouch for use. An inorganic oxide vapor-deposited film is provided on at least one surface of a base film, and a general formula R 1 n M (OR 2 ) is formed on the surface of the inorganic oxide vapor-deposited film. m (wherein R 1 and R 2 are organic groups having 1 to 8 carbon atoms, M is a metal atom, n is an integer of 0 or more, and m is an integer of 1 or more). A barrier film 4 containing the above alkoxide, a polyvinyl alcohol resin and / or an ethylene / vinyl alcohol copolymer, and provided with a gas barrier coating film 3 obtained by polycondensation by a sol-gel method; The present invention relates to a pouch for retort made of a laminated material in which a barrier resin layer 5 and a heat-sealable resin layer 6 are laminated, and further made by using the laminated material.
