    • PROBLEM TO BE SOLVED: To easily produce a multi-chamber packaging bag in which on a surface film side and a back film side, housings partitioned by a division film held between both are formed respectively, and opening widths of the housing on the surface film side and the housing on the back film side are different from each other by the slight improvement of existing equipment and a small number of times of sealing. SOLUTION: The surface film 1, the division film 2, and the back film 3 are laid to overlap each other by making low melting point sealant layers 4a and 4a and high melting point sealant layers 4b and 4b oppose each other, respectively. After or before low-temperature lateral sealing, the high melting point sealant layers 4b and 4b and the low melting point sealant layers 4a and 4a are heated to the sealing temperature region of the high melting point sealant layers 4b and 4b to form both side edge fusion parts 5 and 5, and by the low-temperature lateral sealing, auxiliary side edge fusion parts 5' and 5' which protrude inside the side edge fusion parts 5 and 5 and heat-fused only the surface film 1 and the division film 2 are formed.

    • PROBLEM TO BE SOLVED: To provide a bag-like container which eliminates a useless part at the exterior of the container to improve the appearance of the container, can efficiently use a limited space upon transporting or displaying the container, and is superior in impact resistance.
      SOLUTION: The bag-like container is formed by sealing peripheries of two overlapping soft packaging materials in a strip form, and a content is enclosed hermetically in the container. Sealed parts are located in the container where the content is enclosed. After sealing the peripheries of the soft packaging materials in the strip form, the interior and the exterior of the soft materials are reversed so as to locate the sealed parts 4, 7 in the container where the content is enclosed.

    • PROBLEM TO BE SOLVED: To provide a method for sealing a resin sheet, which eliminates much labor required for sticking mesh to a seal bar, prevents seal wrinkles from forming at the sealing part, and is excellent in appearance and a sealing strength.
      SOLUTION: The sealing method for the resin sheet comprises overlapping a molding resin sheet formed three-dimentionally with another sheet, vertically holding the overlapped section between two sealing bars 5, heating the overlapped section, and sealing the section two-dimentionally. In this sealing method, the contacting surface of the sealing bars 5 to be in contact with at least the molding resin sheet of the two sealing bars 5 is embossed. In this case, the emboss 6 is preferably executed by means of the sand blast machining using the abrasive of #20 to 60. The bag body is produced by sealing the resin sheets by the sealing method.
