Claims

[Claims for Utility Model Registration] 1. After closing the bottom end of a multilayer cylindrical body whose mouth end is cut in a straight line and filling it with contents, the innermost layer is removed along both side edges of the mouth end. , at least the first layer in the outermost layer
forming a closure flap by making a cut that reaches the fold line, leaving one wall of the outer layer forming the flap and folding the entire other part along the first fold line; In a multilayer bag for double-fold sealing, the multilayer bag is sealed by folding the upper part along the second fold line that overlaps with the edge of the folded part and sticking it to the bag body, at least at the opening end of the multilayer bag. A multilayer bag comprising a notch reaching the first opening fold line in at least the outermost layer, excluding the innermost layer, along the side edge on the introduction side to the sealing machine. 2. The lower end is a distance from the mouth edge of the multilayer bag that is at least four times the depth of the cut at the mouth end, and is closer to the center of the bag, and has a width wider than the depth of the cut. The multilayer bag according to claim 1, wherein a hot melt adhesive is applied in a band shape over the entire width of the wall surface where the flap is not formed.
