An opening 3 is formed in the upper part of the bag body 1, and a sealing piece 4 is formed by extending one piece 1a of the bag body 1 from the opening 3 to the other piece 1b.

Further, on the other piece 1b side of the bag body 1,
An adhesive 5 is provided slightly below the opening 3.

On one side 1a of the bag body 1 corresponding to the position of the other piece 1b on which the adhesive 5 is provided, an adhesion inhibitor 6 made of a medium ink is provided.

As shown in FIG. 4, a large number of the packaging bags 7 having such a configuration are stacked, and a bag stack 8
Are formed.

More specifically, a large number of wrappings are provided so that the adhesion inhibitor 6 on one side 1a of the packaging bag 7 and the adhesive 5 on the other side 1b of the packaging bag 7 adjacent thereto come into contact with each other. Bag 7, ...
Are overlapped to form the bag stack 8.

Next, the bag stack 8 having the above-described structure is formed.
In the following, a description will be given of a case in which an object to be packaged is packed in each of the packaging bags 7. First, the bag assembly 8 is placed on a table or the like, and in this state, as shown in FIG. The article to be packaged 9 is stored in the packaging bag 7.

Next, as shown in FIG. 6, the uppermost packaging bag 7 containing the articles 9 to be packaged is peeled off from the bag assembly 8.

In this case, the adhesive 1 provided on the other side 1b of the bag body 1 of the adjacent (lower side) packaging bag 7 is provided on one side 1a of the bag body 1 of the uppermost packaging bag 7. Since the adhesion inhibitor 6 is provided at the position corresponding to the position 5, the adhesive 6 of the adjacent packaging bag 7 adheres to the portion of the uppermost packaging bag 7 where the adhesion inhibitor 6 is provided. And that
Therefore, the uppermost packaging bag 7 can be easily peeled off from the adjacent packaging bag 7.

Thereafter, the sealed piece 4 is sealed and adhered to the other piece 1b side of the bag body 1 via the adhesive 5, whereby the article to be packaged is packaged.

Next, the article to be packaged 9 is stored in the packaging bag 7 below the peeled packaging bag 7, peeled off from the bag assembly 8, and the sealing piece 4 is sealed. The packaged object is packaged in the packaging bag 7.

By sequentially repeating this, the articles 9 to be packaged are sequentially placed in a large number of packaging bags 7 constituting the bag stack 8.
Will be packaged.

In the above embodiment, the other piece 1b of the bag body 1 is used.
And an adhesive 5 is provided slightly below the opening 3 and an adhesion inhibitor 6 is provided on one side 1a of the bag body 1 corresponding to the position of the other piece 1b on which the adhesive 5 is provided. However, the position where the adhesive 5 and the adhesion inhibitor 6 are provided is not limited to this, and for example, as shown in FIG.
An adhesive 5 may be provided on one side of the sealing piece 4 and an adhesion inhibitor 6 may be provided on the other side.

As shown in FIG. 9, the film at the end of the bag body 1 opposite to the opening 3 is extended, and a reinforcing piece 10 made of synthetic paper or the like is sealed in the extended film. It is also possible to form the header 11.

Further, in the above-described embodiment, the adhesion inhibitor 6 made of a medium ink is used as the adhesion inhibitor for inhibiting the adhesion of the adhesive, but the type of the adhesion inhibitor 6 is not limited to this. For example, it is also possible to use an adhesion inhibitor 6 made of a silicone resin.

Furthermore, the adhesion preventing means is not limited to the means using such an adhesion inhibitor 6, and a corona discharge treatment is performed on the film side on which the adhesive is provided and a corona discharge treatment is performed on the film side on which the adhesive is not provided. An untreated surface which is not subjected to the treatment and is not subjected to the corona discharge treatment may be used as the adhesion preventing means.

That is, as shown in FIG. 10, the other piece 1b of the bag body 1 is subjected to a corona discharge treatment to form a treated surface, and the other piece 1b, which is the treated surface, is provided with an adhesive 5 to form a bag. The piece 1a of the main body 1 is not subjected to the corona discharge treatment and is made to be an untreated surface, so that the adhesive 5 of the packaging bag 7 of the bag assembly 8 is formed.
Is a piece of the bag body 1 on the untreated side of the adjacent packaging bag 7
Since it adheres to 1a, it can be easily peeled off.

In this case, the purpose of the corona discharge treatment applied to the other piece 1b side of the bag body 1 can be achieved by applying it to only a part where the adhesive 5 is provided. Need not be subjected to corona discharge treatment.

Further, as shown in FIG. 11, a double-sided tape 13 having two types of adhesives having different adhesive strengths is provided on the other piece 1b side of the bag body 1 and slightly below the opening 3. May be configured to prevent adhesion.

That is, if the surface of the double-sided tape main body 14 provided with the adhesive 15 having the stronger adhesive strength is attached to a position slightly below the opening 3 on the other piece 1b side of the bag main body 1, When a large number of such packaging bags 7 are stacked to form a bag assembly 8, one side 1 a of the bag body 1 is bonded to the adhesive 16 of the adjacent packaging bag 7 with the weaker adhesive force of the double-sided tape 13. To glue
Even if the packaging bags 7, 7 adjacent to each other are forcibly peeled off,
Due to the difference in the adhesive strength between the adhesive 15 and the adhesive 16, the double-sided tape 13 does not move to the adjacent packaging bag 7 side.

Therefore, in this case, the other side 1b of the bag body 1 provided with the double-sided tape 13 is an adhesive surface,
The piece 1a side of the bag body 1 in which nothing is provided consequently becomes the adhesion preventing surface.

Further, as shown in FIG. 12, a reinforcing piece 17 can be provided on the inner surface side of the sealing piece 4.

Further, in the present invention, the main body of the bag 1 is a packaging bag made of synthetic resin, but the material is not limited to this.

The use of the packaging bag of the present invention is not limited.

[0036]

As described above, in the present invention, an opening is formed at one end of the bag body, and one piece of the bag body is extended from the opening to form a sealing piece. In a packaging bag in which the sealing piece is bonded to the other side of the bag body via an adhesive, a surface opposite to the surface on which the adhesive of the sealing piece is provided, or an adhesive of the other piece of the bag body is provided. One side corresponding to the closed position is configured so that it can be peeled off even if it is bonded to the sealing piece of the adjacent packaging bag or the other piece of the bag body via an adhesive, so that such a packaging bag The surface opposite to the surface on which the adhesive of the sealing piece is provided, or one side corresponding to the position where the adhesive of the other piece of the bag body is provided, the sealing piece or the bag body of the adjacent packaging bag. By stacking a large number of packaging bags by peelably adhering to other pieces via an adhesive to form a bag assembly , Accommodating the article to be packaged in packaging bag,
After being peeled off from the adjacent packaging bag, the sealing piece is sealed, and this is repeated for each packaging bag, whereby it is possible to continuously pack the items to be packaged in a large number of packaging bags.

In particular, the back side of the sealing piece or one side of the bag body corresponding to the position where the adhesive is provided on the sealing piece or the other piece of the bag body can be peeled off even after bonding. Therefore, when one packaging bag is peeled off from the bag assembly, it can be easily peeled off. As a result, the conventional release material is not required, and thus the operation of peeling the release material is not required. In addition, there is an effect that the packaging operation of the objects to be packaged by a large number of packaging bags becomes much easier than before, and the operation time of the packaging operation can be shortened as compared with the conventional case.

Further, since the release material is not required, there is an effect that the problem of industrial waste due to disposal of the release material does not occur unlike the related art.

Further, by forming the above-mentioned bag assembly, there is an advantage that each packaging bag does not vary.
