  For convenience of explanation, the flexible packaging material according to the embodiment of the present invention will be described following the manufacturing process. This embodiment is a soft packaging material composed of a single flexible film 1.

  That is, as a first step, as shown in FIG. 1, a roll-shaped flexible film 1 is unwound and traveled, and an adhesive is applied in the vicinity of the side end portion to form a linear sealing adhesive layer 2. Form. As will be described later, the linear sealing adhesive layer 2 is used when the contents are stored and then the opening is sealed to fix the contents.

  Next, as a second step, as shown in FIG. 2, one film provided with the linear sealing adhesive layer 2 is folded from a fold line b substantially parallel to the linear sealing adhesive layer 2. The other film is superposed on a part of the film and sealed with a seal line c in a direction perpendicular to the folding line b. At this time, the fold line b is selected so that the end a of the other film 1 is folded at a position where it does not reach the adhesive layer 2.

  And as a 3rd process, as shown in FIG. 3, the flexible packaging material which concerns on this invention can be manufactured by punching this film in a predetermined position.

  Part of the punching position is the four corners of the film. By punching out the four corners, the resulting soft packaging material can be processed into a cross in plan view. That is, in the packaging material, the one film provided with the sealing adhesive layer 2 has a cross-like shape in plan view, that is, the left region 13 and the right region on the left and right of the central region 10. 12, a lower region 11 below the central region 10, and an upper region 14 above the central region 10.

The other film is overlapped with the one film in the central region 10, the left region 13, the right region 12, and the lower region 11, and these one film and the other film are end portions of the left region 13. At the end of the right region 12 and fixed to each other by a seal line c, the central region 10, the left region 13, the right region 12 and the lower region 11 constitute a content storage portion.

  More specifically, the central region 10 is a region where one film and the other film are overlapped, and these two films are not bonded to each other in the central region 10. Also in the left region 13, these one film and the other film are overlapped. And in this left area | region 13, two films are mutually fixed by the seal | sticker line c of the edge part on the opposite side of the center area | region 10, ie, the left side edge part of illustration. Also in the right region 12, two films are overlaid. In the right region 12, the two films are fixed to each other at the end opposite to the central region 10, that is, the seal line c at the right end in the figure.

  In the lower region 11, one film and the other film are overlapped. In the lower region 11, the end on the opposite side of the central region 10, that is, the lower end in the figure is a fold line b. At the end of the lower region 11, these films are fixed to each other by the fold line b.

  Next, the upper region 14 is composed of the one film, and the linear adhesive layer 2 is provided in the vicinity of the end portion.

  When punching the four corners, it may be punched at the same position as the end a of the film 1, but it is desirable to punch at a position that does not reach the end a in consideration of variations in positional accuracy. FIG. 3 shows such a soft packaging material. That is, d shown in the figure is a punching line, and the end a remains even after punching from the punching line d.

  Next, the other part of the punching position is inside the left region 13. By cutting the inside of the region 13, the cut 3 can be formed in the film 1. Since two films are overlapped in the left region 13, both of the two films can be punched out to form a cut 3 at a position corresponding to each other. The cut 3 constitutes a handle when the soft packaging material is used. In addition, when the contents to be stored are provided with a handle, the handle of the content can be pulled out from the cut 3 and used.

  As shown in FIG. 3, it is desirable that the cut 3 has a U-shape. Further, it may be U-shaped. 4 (a) and 4 (b) show examples of such cut shapes.

  Moreover, it can replace with the cut | interruption 3 and can also be set as the through-hole 3 '. FIG. 5 shows an example of a flexible packaging material in which a through-hole 3 ′ is formed by punching out both the one film and the other film that are overlapped with each other.

  As mentioned above, although the manufacturing method of the flexible packaging material comprised from the sheet of flexible film 1 and the manufactured flexible packaging material were demonstrated, it is also possible to manufacture a flexible packaging material using two sheets of flexible films. is there.

In this case, as a first step, an adhesive is applied to the vicinity of the side end of one of the two flexible films to form a linear sealing adhesive layer 2. Next, as the second step, the other film is superimposed on a part of the one film provided with the linear sealing adhesive layer 2 and sealed with a seal wire. The position of this seal line is the end of the lower region in addition to the end of the left region 13 and the end of the right region 12.

  And as a 3rd process, the flexible packaging material which concerns on this invention can be manufactured by punching this film in a predetermined position. The punching position is the same as in the case of manufacturing from a single flexible film.

  Next, the usage method of this flexible packaging material is demonstrated with reference to FIGS.

  That is, as shown in FIG. 6, the contents storage portion A can be opened by opening two films stacked on each other. The storage portion A has a rectangular shape, and its bottom surface is constituted by a lower region 11. In addition, the periphery is surrounded by a central region 10, a left region 13, and a right region 12. As described above, since the central area 10 is an area where the two films 1 are overlapped, in the illustrated example, the two films are positioned on the front side and the rear side of the storage portion. Moreover, the left area | region 13 and the right area | region 12 are located in the right and left of a storage part. In addition, between the lower area | region 11 and the left area | region 13, and between the lower area | region 11 and the right area | region 12, it is a part of the punched four corners, and the clearance gap is opened.

  Next, FIG. 7 shows a state in which the upper region 14 is on the lower side. And in this state, as shown in FIG. 8, the contents B, such as a diaper pack, are inserted and stored in the storage part A from the opening. A plurality of contents B such as diaper packs can be stored in a stacked state. In this example, the diaper pack B includes a handle B1, and when the diaper pack B is stored, the handle B1 is inserted so as to face the cut 3 or the through hole 3 '. In FIG. 8, the arrow x indicates the insertion direction.

  After the contents are stored, the opening can be covered with the upper region 14 and bonded to the central region 10 using the adhesive layer 2 to fix the contents to the storage portion (FIG. 9). As described above, there is a gap in the storage portion, and therefore, the storage portion is not sealed. However, since the entire content is surrounded by each region of the packaging material, it does not fall out. In addition, as a content, if it is a large sized product which does not fall out from a clearance gap, it may be arbitrary things, but a paper diaper pack can be illustrated as the representative example. It is possible to store two or more disposable diaper packs depending on the size of the storage unit. In addition, when the handle B1 is provided in the contents, as shown in FIG. 10, the handle B1 can be used by being exposed to the outside through the cut 3 or the through hole 3 '. When the handle B1 is not provided in the contents, the film between them can be used as the handle portion by passing the finger through the cut 3 or the through hole 3 '. Further, when the cut 3 has a U-shape or U-shape, the film turned from the cut 3 can be wound around the handle part or the content handle B1 for use.

  And the package formed by accommodating the contents can use the cut 3 or the through-hole 3 ′ as a handle by standing the package (see FIG. 10). Even in the standing state, the contents are fixed by the respective regions, so that they do not fall out.

  Next, as the film 1, any film can be used as long as it is flexible and has a strength that can withstand the weight of the contents. For example, synthetic resin films such as polyethylene, polypropylene, polyester, and polyvinyl chloride. Moreover, the laminated body which laminated | stacked these synthetic resin films can also be utilized as the film 1. FIG. For example, a laminated film having a sandwich structure in which a polypropylene film is laminated on both sides of a polyethylene film.

Moreover, as an adhesive which can be used for the adhesive layer 2, a pressure-sensitive adhesive which can be easily peeled and can be re-adhered can be preferably used. For example, an acrylic resin emulsion type re-adhesive pressure sensitive adhesive. As the adhesive layer 2, it is also possible to apply a double-sided adhesive tape to the film 1 and use the exposed adhesive layer.

  It is also possible to use an adhesive that cannot be re-adhered. For example, it is a pressure-sensitive adhesive that cures with time after being bonded to the central region 10. In this case, it is desirable that a cut line is provided in a part of the upper region 14 so that it can be opened from the cut line. As a cut line, the perforation which penetrates the film 1, and a cut tape can be illustrated, for example.
