PROBLEM TO BE SOLVED: To provide a barrier laminated material which is useful as a packaging material capable of decreasing amounts of solid wastes of a container and packaging by making a film of an extruded resin layer becoming an adhesive layer for the laminated material thin to improve the barrier property, and to provide a packaging bag using the same. SOLUTION: A vapor deposition film of an inorganic oxide is provided on one side surface of a substrate film, and at least a primer agent layer, an extrusion resin layer and a heat sealing resin layer are successively laminated on the vapor deposition film of the inorganic oxide to provide the laminated film. Then, the packaging bag using the same is provided. COPYRIGHT: (C)2004,JPO
