摘要： A method for manufacturing a rectangular-bottomed packaging bag includes an unfolding step of unfolding a flat bag by separating a pair of opening/closing plates (13) inserted into the flat bag from each other in a thickness direction of the flat bag, and a gusset forming step, after the unfolding step, of forming a side gusset and a bottom gusset by thrusting folding plates (11 and 12) between the pair of opening/closing plates (13) from the outside of the bag toward the inside of the bag.

摘要： The present invention is a self-standing spout-equipped packaging bag (1), including a bag body (10) that stores contents, and a spout (12) that is attached to an upper portion of the bag body (10). The bag body (10) includes a tubular barrel portion (20), and a bottom portion (22) which is attached to block an opening end of a lower part of the barrel portion (20). The spout (12) includes a tubular nozzle portion (14), and a flange portion (16) which projects from an outer surface of the nozzle portion (14). An upper end part (21) of the tubular barrel portion (20) over an entire circumference is liquid-tightly adhered to an upper surface (16e) of the flange portion (16) in a state of following a shape of the flange portion (16) in plan view to be in the same shape.

摘要： A gusset bag includes: a pair of flat surface portions facing each other; and a pair of side surface portions facing each other and folded inward of the gusset bag. A containing portion used to contain an object is formed using the flat surface portions and the side surface portions. The gusset bag has a side edge-sealing portion in which a side edge portion of a flat surface portion of the flat surface portions and a side edge portion of a side surface portion of the side surface portions are heat-sealed together, and a folded-back portion in which the entire side edge-sealing portion is folded back and affixed to the flat surface portion or the side surface portion that forms the containing portion. The peel strength of the folded-back portion is lower than the peel strength of the side edge-sealing portion.
