SOLUTION: The cartridge-type bag 100 comprises a plastic pour-out port 20 which can be opened/closed heat-bonded with a part of an upper portion of the bag made of a laminate film. In addition, a plurality (four in the figure) of strip-formed reinforcing sheets 15 with a predetermined width (a) are laterally stuck on both external surfaces of the bag respectively with an interval b of a predetermined length and at overlapping positions on the front and the back of the bag. |
