PROBLEM TO BE SOLVED: To provide a cartridge-type bag for seal-packaging a viscous liquid such as ink to be mounted whole on a printer or the like for use wherein an empty bag is not bulky, air does not enter the bag during use, little residual of the ink or the like remains after use, and the bag is excellent in economy and disposability as well as usability. SOLUTION: The cartridge-type bag 100 is formed of a laminate film bag having a plastic pour-out port 20 which can be opened/closed joined with a part of an upper portion and a cover film 15 to be mounted to cover an outer periphery of a barrel of the bag. In addition, the cover film 15 is stuck to a wall face film on both front and rear of the bag in such a form that adhesive regions 16 of a predetermined length and non-adhesive regions 17 of a predetermined length are alternately arranged in at least a longitudinal direction of the bag. |
