The Moreover, a bag having a form called a “U-back” in which there is no tongue between the hand-held portions is formed.

In the case of a bag with handbags on both sides of the upper part of the bag body, it is convenient to have a handbag when carrying things in, but when handing over multiple sheets, the handbags will be scattered and handled. May cause inconvenience.
In such a case, it is preferable that the handbags are grouped together by a unit, for example, a binding unit such as a bundle or welding.
In the case of a bag material in which the handbag and the bag body are integrated, the handbag is not separated, which is convenient for handling.
Further, a bag material in which a coupling element is provided on the tongue piece, and a separation element is formed so as to surround the coupling element, and a bag is formed in which the hole is formed when the bag material is separated from the bag material assembly Can be used by passing one tongue piece through the hole of the other tongue piece.

  As the attachment element, for example, a double-sided adhesive tape can be suitably used. Instead of the double-sided adhesive tape, an adhesive may be applied to the bag assembly or the bag material assembly attachment side. When the holding tool is provided with a hooking means, for example, a hook, a hole for hooking the hook may be used. In addition, there is no particular limitation as long as it can be attached to a holder such as a string can be used.

  A container can be suitably used as a holder for holding the bag assembly or the bag material assembly. The container can be used for any purpose such as a garbage container or a parts container. Moreover, the frame may be formed of a tube body or a rod body, and a holder having a structure for holding the bag assembly or the bag material assembly may be used. There is no particular limitation as long as the bag assembly or the bag material assembly can be held.

The sheet on the adhesive tape 17 direction side is left on the bag assembly 1 side without being peeled off.

When the sheet 101 that is the upper side of the bag 10 is peeled off from the bag assembly 1, the sheet 101 is peeled off from the location of the separation element 15, and the separation portion 16 is removed from the sheet 101 that is the upper side of the bag 10. A handle hole 18 is formed in the bottom.
Then, the opening portion 11 is opened while the sheet 102 that is the lower side of the bag 10 is left on the bag assembly 1 side, and the opening edge B3 of the container B is placed over the edge of the opening portion 11.

  When a necessary amount of contents, for example, garbage, is collected in the bag 10, the sheet 102 on the lower side of the bag 10 is peeled off from the separation element 15, and the bag 10 is removed from the bag assembly 1. When peeling off, the separation portion 16 is removed from the lower sheet 102, and the handle hole 18 is formed in the sheet 102.

  As a result, the entire bag 10 is separated from the bag assembly 1, and a handle hole 18 having a size that allows fingers to enter the sheets 101 and 102 on both sides of the bag 10 is formed. The size of the handle hole 18 may be set appropriately depending on the weight of the stored item, such as the size of one finger if the weight of the stored item is light, or the size of the handle if it is heavy. .

  Thereafter, the bag 10 is pulled up and removed from the container B (see FIG. 4 (c)), and the bag 10 located in the upper layer is attached to the container B in the same manner as described above, and sequentially in the same manner. All the bags 10 of the bag assembly 1 are used.

  After all the bags 10 are used, the separation part 16 having the coupling holes 14 remains as a lump of sheet separation pieces and remains adhered to the container B side. Therefore, the separation part 16 is removed, and a new bag assembly 1 is removed. Used in the same way as
