PROBLEM TO BE SOLVED: To provide a pasting method of a soft packing film for a soft packaging bag container capable of being easily formed into a bag without using complicated bag making equipment, having high tensile strength and housing and packaging a liquid, a solid, a powder, a granular material, etc. , and the soft packaging bag container formed by the pasting method. SOLUTION: In a state that an adhesive film having a welding layer is inserted in the gap between two films having welding layers applied to one sides thereof in opposed relationship so that the welding layer of the adhesive film comes into contact with the welding layers of the films, preferably in a state that the adhesive film to be used having the welding layer on one side thereof is folded back so that the welding layer appears outside to be inserted in the gap between the opposed films, the films opposed to each other in the same way as butt seam are welded from the outside by a heater. By this method, a bag making method becomes simple, welding is performed at two places, the same pasting as envelop pasting is performed and the container high in tensile strength can be provided.
