。[Claims for Utility Model Registration] 1. A multilayer cylindrical body with at least one end cut into a straight line among both ends of the mouth floor, excluding at least the innermost layer of the straight cut end, and at least the outermost layer. A cut is made along the fold line to a first fold line parallel to the linear cutting line to form a closure flap, and the other portion is folded inward along the first fold line, leaving the flap. , further folding the closing flap portion and the folded portion along a second folding line between the tip of the folding portion and the first folding line, and folding the closing flap portion into a bag. A double-fold sealed multi-layer bag that is pasted and sealed on the main body. 2 The linearly cut end of the multilayer cylindrical body, in which at least one end of both ends of the mouth floor is cut linearly, is aligned with the first bending line parallel to the linearly cut line. Then, fold along the second fold line between the tip of the folded portion and the first fold line, and attach and seal the tip of the folded portion to the bag body using reinforcing tape. Double-fold sealed multi-layer bag. 3 At least one end of the multi-layered cylindrical body is cut in steps out of both ends of the mouth floor, except for at least the innermost layer of the cut end, along the fold line of at least the outermost layer, parallel to the cut part in steps. a closure flap is formed by making a cut that reaches the first fold line; the other portion is folded inwardly along the first fold line, leaving the flap; Fold the closing flap portion and the folded portion inward along a second folding line between the mouth portion of the innermost layer, and attach the closing flap portion to the bag body.
A double-fold sealed multi-layer bag. 4. Fold the step-cut end of the multi-layered cylindrical body in which at least one end of the both ends of the mouth floor is step-cut inward along the first bending line parallel to the step-cut cut section, and then fold the step-cut end into the first fold. Fold it inward along the second fold line between the fold line and the mouth edge of the innermost layer of the folded part, and attach and seal the tip of the folded part to the bag body with reinforcing tape. A double-fold sealed multi-layer bag.
