PURPOSE:To enable automatic filling of a bal provided with an opening means by a method wherein an opening and closing device is bent into a U-shape to have a male groove and a female groove engaged, and t the same time constitution is made so that one of the lower ends of this opening and closing device is sealed onto one of the upper ends of the bag. CONSTITUTION:On an opening and closing device, a male groove 5 and a female groove 6 are molded in parallel by extrusion on the same plane of the tape 4, and this tape 4 is two-folded at the middle of the tape to have the male groove 5 and the female groove 6 engaged with each other. A part of the lower end 7 of an opening and closing device 3 is inserted into a part to be an opening of a bag 1, and one of the lower ends 8 is heat-sealed onto one of the upper ends 8 of the bag 1. A hopper 11 is inserted into this mouth 2 to fill contents 12 in the bag. After this filling, both sides of the mouth 2 of the gag 1 is pressed between a cooling bar 10 and a heating bar 9. The unsealed side of the bag 1 is heat-sealed with this pressing. A film to be used is not specially limited as far as the melting point of the inner of the bag 1 and the outer of the tape 4 is lower than that of the outer of the bag 1 and the inner of the tape 3, respectively.
