The product packaging bag 10 includes a front film 20 made of, for example, a transparent and relatively soft synthetic resin film.
And a backside film 30. The front side film 20 and the back side film 30 have a rectangular shape with the same width in a front view, and their side edges 20a, 30a are connected to each other, and the bottom edges 20b, 30b are connected to each other, and a bag portion having an open upper portion. 15 is formed. The welding of both side edges 20a, 30a of the front film 20 and the back film 30 is performed by cutting and welding the film material at the same time by applying a predetermined hot plate in a state where the front film material and the back film material are overlapped. It can be achieved by doing. In this embodiment, the front side film 20 and the back side film 30 are connected to the bottom edges by folding a series of films, but the bottom edges of the separately prepared front side film and the back side film are connected to each other. May be connected by welding.

As best shown in FIGS. 1 and 2,
The front film 20 has an extending portion 21 that extends a predetermined length further above the upper edge of the back film 30.
On the back surface of the extending portion 21, a synthetic resin plate-made core material 40, which is formed thicker than the front and back films and is provided with rigidity, is integrally welded over the entire surface, whereby the base portion of the extending portion 21 is formed. A lid portion 50 that can be folded back is formed by the folding line 22 corresponding to. Such integral welding of the film and the core material can be achieved by applying heat in a state where the core material 40 and the extension portion 21 are laminated.

On the back surface of the lid portion 50 formed as described above, the adhesive 61 is provided along the tip edge of the lid portion 50.
Is applied in a strip shape, and release paper 62 is attached so as to cover the adhesive 61.

The lid portion 50 also has a hanging portion 70 which can be easily cut and raised. That is, as shown clearly in FIG. 1, the lid portion 50 has a substantially U-shaped cut-and-raised line 51 having a start point 51a and an end-point 51b on the turn-back line 22. The tongue-shaped hanging portion 70 can be cut and raised along the line 51. The cut-and-raised line 51 can be formed by, for example, a perforation line 51 'in which narrow through holes are arranged in a broken line. Hanging part 70
In addition, a round hole-shaped hanging hole 71 is also formed in.
The perforation line 51 'and the hanging hole 71 can be easily formed by punching.

The product packaging bag 10 having the above structure is, for example,
It can be manufactured as follows.

First, as shown in FIG. 7, a synthetic resin film material 10 'having a predetermined width is folded in two while being conveyed in the longitudinal direction. The film materials 20 'and 30' that are folded and overlapped in this manner are the front side film 2 described above.
0 and the backside film 30. Therefore, the backside film is folded such that the width of the frontside film is longer than that of the backside film by an amount corresponding to the extension for forming the lid 50. At this time, for convenience of the step of welding the core material to the lid portion and the step of applying the adhesive material to the lid portion and pasting the release paper, the back side film material 30 'is on the top side and the front side film material 20' is on. Is being transported so that it is below.

Next, as shown in FIG. 8, a core made of a relatively thick synthetic resin plate having a width corresponding to the width of the extending portion 21 'on the extending portion 21' of the front film material 20 '. Material 4
0'is entirely welded. This step can be easily performed by attaching the core material 40 'to the extending portion 21' and sandwiching them by a heat roller or the like.

Next, as shown in FIG. 9, perforation lines 51 'and hanging holes 71 are punched out at predetermined pitch intervals in the polymer welded portion 50' between the extending portion 21 'and the core material 40'. Formed by.

Further, as shown in FIG. 10, an adhesive 61 is applied in a strip shape along the end edge 50a 'of the above-mentioned welded portion 50' of the extending portion 21 'and the core material 40'. Is
At the same time, the strip-shaped release paper 62 is stuck on the adhesive 61 thus coated.

Finally, as shown in FIG. 11, an intermediate product that has undergone the above-mentioned steps is transported, and a predetermined hot plate is used to heat-fuse each of the predetermined widths in the predetermined transport direction to cut individual product packaging bags. 10
Is obtained. By this heat cutting process,
The front side film 20 and the back side film 30 of the individual product packaging bags 10 are simultaneously welded at both side edges 20a, 30a.

The product packaging bag 10 can be selected to be displayed on a flat display stand or to be hung and displayed on a hanging bar as follows.

That is, in the case of displaying on a flat display stand, after the goods are stored in the bag portion 15, the bag shown in FIGS.
As shown in, the release paper 62 on the back surface of the lid portion 50 is removed to expose the adhesive 61, and the lid portion 50 is attached onto the backside film 30 and the bag portion 15 is sealed.
To display. In this case, since the portion that does not contribute to the storage of the product does not extend from the bag portion 15, it is possible to efficiently use the display space and perform the planar display. Also, it is efficient in packaging and transporting a large number.

On the other hand, in the case of hanging display, as shown in FIG.
And, as shown in FIG. 6, the suspending portion 70 attached to the lid portion 50 is cut and raised along the perforation line 51 ′,
The hanging hole 71 of the hanging portion 70 is passed through a hanging bar to perform a hanging display. In this embodiment, the lid portion 50 is provided with rigidity by welding the core material 40 to the back surface side of the extending portion 21 of the front film 20, and the hanging portion 70 also extends. Since the core material 40 is welded to the back surface side of the to have rigidity,
Even when a comparatively heavy product is stored in the bag portion 15, the rigidity of the lid portion 50 provides shape retention to the entire bag portion, and the shape of the bag portion 15 is deformed due to the weight of the product, so that the product is displayed. The appearance does not deteriorate, and the problem of losing the weight and tearing the hanging hole 71 of the hanging portion 70 can be avoided.

12 and 13 show a second embodiment of the product packaging bag according to the present invention. In the second embodiment, the configuration of the hanging portion 70 is modified as compared with the first embodiment. That is, in the second embodiment, the hanging hook 70 is formed by making an L-shaped cut in the hanging portion 70, and by doing so, the hanging portion is provided on the hanging rod side. You can make a hanging display by hooking it from one side. Since other configurations are similar to those of the first embodiment described above,
The description is omitted. Even in this case, after sealing with the lid part 50, the hanging part 70 is not cut and raised, and the exhibition is performed on a flat display stand, and the hanging part 70 is cut and raised and hung on a hanging rod. It is possible to expect the same operational effect as described above, in which it is possible to select whether to display the display in a lower position.

14 and 15 show a third embodiment of the product packaging bag according to the present invention. In this embodiment, as compared with the second embodiment, the vertical dimension of the core material 40 that is entirely welded to the lid portion 50 is made smaller. That is, the dimension of the core material 40 from the folded line 22 is determined by the hanging portion 7
0 is formed in a size sufficient for forming 0, and the tip end of the extended portion 21 of the front film 20 is left in a state in which the core material is not attached, and the strip-shaped adhesive 61 is applied to this portion, and
The release paper 62 is attached. By doing so, since the portion to which the adhesive 61 is applied retains its flexibility, even if the product housed in the bag portion 15 has irregularities, the tip of the lid portion 50 is placed on the back side depending on the irregularities. Along with the film 30, reliable sealing can be achieved. It will be easily understood that the same effects as those described above can be expected in this embodiment as well.

Of course, the scope of the present invention is not limited to the above embodiment. The size of the packaging bag 10,
The shape of the hanging portion can be variously changed. The cut-and-raised line for easily cutting and raising the hanging portion may be formed by a thin-walled portion in addition to the perforation line.

Further, in the above embodiment, the lid 50
Although the adhesive 61 for sealing is applied to the back surface of the above, even if the adhesive is applied to a predetermined portion of the back film 30, the bag 15 can be sealed when the lid is folded back. Of course, in this case, the release paper is attached on the adhesive.
