Can be peeled off from the film sheet 13 without damaging the bag body 2 after peeling. Note that the adhesive sheet 3 attached to the adherend 18 is
What is necessary is just to discard with the adherend 18 as it is.

The bag 2 peeled off from the adhesive sheet 3 can be used as it is for storage or preservation in a state where the storage documents are stored. In the case of the illustrated example, the bag 2 has a sealing piece 10 that can be opened and closed via a pressure-sensitive adhesive tape 12. After the storage document is taken out from the bag 2, the storage document is stored in the bag 2 again. By doing so, it can be provided as a bag for storage or preservation.

[Embodiment of Manufacturing Method of Storage Bag] The storage bag according to the above embodiment is manufactured by the steps shown in FIG.

The continuous strip-shaped adhesive sheet material 3a for forming the above-mentioned adhesive sheet 3 is not shown in the drawing,
It is unwound from the wound roll and transported in the belt longitudinal direction. That is, as described above, the adhesive sheet material 3a has a laminated structure in which the weak welding means 17 is laminated on the front surface of the film sheet 13 and the adhesive layer 14 and the release sheet 15 are laminated on the rear surface. It is configured.

Although not shown, the continuous band-shaped bag material 2a for forming the bag body 2 is unwound from a wound roll and transported in the longitudinal direction of the band. That is, the bag material 2a forms the front and back film portions 5 and 6 by polymerizing the film in half as described above, and the back film portion 6 includes the sealing piece 10 and the adhesive tape 12 with the release tape 11. And is formed in a continuous band shape.

In the process of continuous transfer, FIG.
As shown in (C), the adhesive sheet material 3a and the bag material 2a

9 is transported intermittently in the longitudinal direction of the band. In the illustrated embodiment, an example is described in which the weak welding means 17 is provided on the adhesive sheet material 3a. However, the weak welding means 17 may be provided on the back film portion 6 of the bag material 2a. What is necessary is to provide beforehand between the film part 6 and the film sheet 13 as described above.

Thereafter, when the intermittently transported laminated strip 19 is stopped, the front and back film portions 5 and 6 of the bag material 2a are welded to each other along a dividing line C orthogonal to the longitudinal direction of the laminated strip 19. To form a bag welded portion 7, and a sheet welded portion 16 is formed by welding the back film portion 6 and the film sheet 13 via a weak welding means 17, and furthermore, laminating along the dividing line C. When the strip 19 is divided, the storage bag 1 having a width corresponding to the intermittent transfer pitch is obtained as shown in FIG.

In the case of the embodiment in which the release sheet 15 of the adhesive sheet 3 is formed of a synthetic resin film, the step of forming the bag welding section 7, the step of forming the sheet welding section 16, and the cutting of the laminated band 19 are performed. The step can be performed by one fusing step along the dividing line C. In other words, if the lamination strip 19 is blown along the dividing line C by the fusing blade, the bag welding portion 7 in which the front and back film portions 5 and 6 are fused and welded to each other is formed at the same time. The sheet welding portion 16 is formed by fusing and welding the back film portion 6 via the weak welding means 17, and the laminated band 19 including the release sheet 15 can be simultaneously blown along the dividing line C. At this time, since the release sheet 15 is provided with a release treatment film such as a silicon film, the release sheet 15 and the film sheet 13 are not welded along the fusing line, but are temporarily welded. Even if it is in a weakly welded state, the release sheet 15 can be separated at the time of later use.

Alternatively, instead of one fusing step, two steps of a fusing step and a fusing step along the dividing line C may be performed. That is, first, by pressing a heating means such as a hot plate along the dividing line C, the bag welding portion 7 in which the front and back film portions 5 and 6 are welded to each other, and the film sheet 13 The back film portion 6 and the sheet welding portion 16 in which the back film portion 6 is welded via the weak welding means 17 are simultaneously formed. Therefore, a band-shaped welding line including the bag welding portion 7 and the sheet welding portion 16 is formed in the width direction of the laminated band-shaped body 19 orthogonal to the band longitudinal direction. Thereafter, when the lamination strip 19 is blown off by a fusing blade along the dividing line C on the strip welding line, the storage bag 1 is obtained.

On the other hand, in the case of the embodiment in which the release sheet 15 of the adhesive sheet 3 is formed of a paper sheet, it is difficult to blow the paper sheet, so that the welding step and the cutting step along the dividing line C are performed twice. The steps may be performed. That is, first, by pressing a heating means such as a hot plate along the dividing line C,
On the laminated strip 19, a bag welding portion 7 in which the front and back film portions 5 and 6 are welded to each other, and a sheet welding portion 1 in which the film sheet 13 and the back film portion 6 are welded through the weak welding means 17.
6 are simultaneously formed. Therefore, a band-shaped welding line including the bag welding portion 7 and the sheet welding portion 16 is formed in the width direction of the laminated band-shaped body 19 orthogonal to the band longitudinal direction. Then, the storage bag 1 is obtained by cutting or cutting the laminated band 19 with a cutting blade along a dividing line C that matches the center line of the band-shaped welding line.

[Other Embodiments] FIG. 5 shows an embodiment in which a protective film 20 is superposed on the surface of the front film portion 5 of the bag 2. As shown in FIGS. 5A and 5B, the protective film 20 is made of a similar synthetic resin film that can be welded to the bag 2, covers the entire surface of the front film portion 5, and It is welded to the front film portion 5 at the bag welding portion 7 on both side edges.

The method of manufacturing the storage bag 1 provided with the protective film 20 is substantially the same as that of the above-described embodiment described with reference to FIG. In addition to the transfer of the sheet material 3a and the transfer of the continuous band-shaped bag material 2a for forming the bag body 2, the continuous band-shaped film material 20 for forming the protective film 20
a is unwound from the wound roll and transported in the belt longitudinal direction.

Therefore, in the process of continuous transfer, FIG.
As shown in (C), the bag material 2a was polymerized and laminated on the surface of the adhesive sheet material 3a, and the film material 20a was polymerized and laminated on the surface of the bag material 2a, thereby forming a laminated strip 19a. Thereafter, the laminated band 19 is intermittently transferred in the longitudinal direction of the band. As in the above embodiment, the weak welding means 17 is provided in advance between the back film portion 6 to be polymerized and the film sheet 13.

Thereafter, the intermittently transported laminated strip 19a
At the time of stopping, the bag welding portion 7 is formed along the dividing line C orthogonal to the belt longitudinal direction of the laminated band-shaped body 19a, and the front and back film portions 5, 6 of the bag material 2a are welded to each other. The front film portion 5 and the film material 20a are welded to each other to form a sheet welding portion 16, so that the back film portion 6 and the film sheet 13 are welded via the weak welding means 17, and Along the lamination strip 1
By dividing 9a, storage bag 1 having a width corresponding to the intermittent transfer pitch is obtained.

The welding and cutting along the dividing line C may be performed in a single cutting step along the dividing line C, as in the above-described embodiment, or may be performed in place of the single cutting step. It may be carried out by two steps of a welding step along the disconnection C and a cutting step by fusing or cutting.

According to this embodiment, the storage bag 1 is stuck to an adherend such as a cardboard box or the like via the adhesive layer 15 of the sticking sheet 3, and the front of the bag 1 storing the storage documents is attached. Since the film portion 5 is protected from the outer surface by the protective film 20, damage due to collision of foreign matter or the like is prevented.

When the bag 2 is peeled off from the adhesive sheet 3, since the protective film 20 is integrated with the bag 2, even when the storage documents are stored or stored in the bag 2, In addition, the bag 2 is reinforced by the protective film 20 and satisfies the long-term durability of the bag 2. still,
The title of the storage document, the trademark of the product, and other indications can be printed on the protective film 20 as appropriate.
