有する粒状物納入袋。 In a plastic film bag with a three-sided seal structure, the film alignment part on the back is made sure that the front and back sides of the film overlap, and the inside part is covered with air-permeable net-like sackcloth tape or other tape having an air-permeable structure. The end of the inner film is heat-sealed, and the outer film of the other overlapping layer is overlapped by heat-sealing, leaving an unsealed area of several mm or more between it and the inner film to create an air vent structure. The outer edge of the cover hides the air vent.
