<Packaging bag>
Hereinafter, embodiments of the packaging bag of the present invention will be described with reference to the drawings, but the packaging bag of the present invention is not limited to the following embodiments. FIG. 1 is a front view schematically showing one embodiment of the packaging bag of the present invention. FIG. 2 is a cross-sectional view taken along the line AA ′ of FIG. As shown in FIGS. 1 and 2, the packaging bag 10 according to the present embodiment includes a packaging bag main body 12 made of a resin film 9 having a bag-shaped storage portion 7 in which the article 5 is stored.

  The packaging bag of this invention may be further equipped with the to-be-stored object 5 accommodated in the accommodating part 7, as shown to FIG. The kind of the article 5 to be stored in the storage unit 7 is not particularly limited. Specific examples of the items to be stored include catalogs, brochures, advertisement flyers, magazines, books, documents, packaged cosmetics, packaged foods, novelty goods, and the like. As a resin film which comprises a packaging bag main body, the film which consists of synthetic resins, such as a polypropylene and polyethylene, can be used, for example. Furthermore, a film made of a biodegradable resin such as polylactic acid can also be used.

  The packaging bag main body 12 has an open end portion 14 that communicates with the storage portion 7 and serves as a loading / unloading port for the storage object 5. In the opening end portion 14, it is preferable that at least a part of the opposing surfaces of the resin film 9 is sealed with a plurality of dot-shaped sealing portions 18 or the like so as to be able to be opened. In the packaging bag 10 of the present embodiment, one end of the resin film 9 is folded back, and the outer surface and the inner surface of the opposing resin film are sealed by the sealing portion 18, thereby forming the bag-shaped storage portion 7. Has been. In addition, the opening end part of the packaging bag of this invention does not need to be sealed as shown in FIG. As a means for sealing at least a part of the opposing surfaces of the resin film so that they can be opened, in addition to means using an adhesive material such as hot melt or (removable) adhesive, a state through a predetermined ink And means for heat sealing (thermal fusion).

  The unsealed end portion 14 communicates with the storage portion 7. For this reason, when the unsealed end portion is sealed, the stored object 5 stored in the storage portion 7 can be easily taken out from the unsealed end portion 14 by releasing the seal. On the other hand, when the opening end portion is not sealed, the object to be stored stored in the storage portion can be taken out from the opening end portion as it is. In addition, the taken-out storage object 5 can be stored again in the storage unit 7 through the unsealed end portion 14.

  Formed portions such as perforations 16 are formed on the resin film 9 constituting the unsealed end portion 14. A handle penetrating in the thickness direction of the superimposed resin film 9 can be formed by opening the shape processing portion such as the perforation 16 with a finger or the like. In addition, a general-purpose packaging machine can be used to form a shape processing part to be a handle by simply processing the resin film itself without attaching a dedicated part (section) to be a handle. Packaging bags can be manufactured in large quantities.

  The shape processing portion is preferably a perforation or a slit because it can be easily formed simply by processing the resin film constituting the packaging bag body. Further, the perforation processing for forming the perforations and the slit processing for forming the slits are different from the punching processing and the like, and the end material such as the punched workpiece is not generated. For this reason, it is preferable because the generated end material is less likely to cause malfunctions due to being mixed into a machine such as a shape processing machine or a packaging machine.

  Specific examples of the shape processed portion include patterns shown in FIGS. 12A to 12E. That is, a pattern (a) in which one perforation is formed, a pattern (b) in which a plurality of perforations are formed in parallel to each other, a pattern (c) in which linear slits are formed, and a U-shaped slit And a pattern (e) in which slits that are partially connected (not cut) are formed. Among these, a pattern (b) in which a plurality of perforations are formed in parallel to each other is preferable. When the plurality of perforations are formed in parallel to each other, the overlapping position of the resin film is shifted, so that the perforations formed for each resin film do not exactly coincide with each other, even if they are slightly shifted, A handle can be formed by easily opening it with a finger or the like.

  FIG. 13 is a schematic diagram for explaining the usage state of the packaging bag. As shown in FIG. 13, the handle 2 can be formed by cutting a shape processing portion such as a perforation in the opening end portion 14 of the packaging bag 10 with a finger or the like. Then, by passing a finger or hand through the formed handle 2, it is possible to easily carry the packaging bag 10 in a state in which the articles to be stored 5 are stored again in the storage portion 7 through the outlet 110. That is, by using the packaging bag of the present invention, it is possible to easily take out stored items such as catalogs, pamphlets, magazines, etc. obtained at various exhibitions, concert venues, etc. It can be stored and easily taken home.

  FIG. 3 is a front view schematically showing another embodiment of the packaging bag of the present invention. In the opening end portion 24 of the packaging bag 20 of the embodiment shown in FIG. 3, at least a part of the opposed surfaces of the resin film 9 is sealed by a linear sealing portion 28 so as to be opened. Thus, the shape of the sealing portion may be a dot shape as shown in FIG. 1 or a linear shape as shown in FIG.

  FIG. 4 is a front view schematically showing still another embodiment of the packaging bag of the present invention. FIG. 5 is a B-B ′ cross-sectional view of FIG. 4. In the opening end 34 of the packaging bag 30 of the embodiment shown in FIGS. 4 and 5, one end of the resin film 9 is not folded back, and the inner surfaces of the opposing resin films are sealed by the sealing portion 18. .

<Method for manufacturing packaging bag>
Next, the manufacturing method of the packaging bag of this invention is demonstrated. The manufacturing method of the packaging bag of this invention is a method of manufacturing the above-mentioned packaging bag of this invention, and has the process (1)-(3) shown below. Hereinafter, the details of the method for manufacturing a packaging bag of the present invention will be described with reference to the drawings.
Process (1): The process of forming a shape processing part in the predetermined location of the long original fabric of a resin film Process (2): The process of folding back a long original fabric so that the formed shape processing part may overlap in the corresponding position Process (3): The process of forming the accommodating part which seals and cut | disconnects a long original fabric, and accommodates a to-be-contained object separately.

(Process (1))
In the step (1), as shown in FIG. 6, a shape processed portion such as a perforation 16 or a cut is formed in a predetermined portion of the long original fabric 100 of the resin film. The portions where the shape processing portions such as the perforations 16 in the long original fabric 100 are formed are formed at the locations where the corresponding shape processing portions overlap when the long original fabric 100 is folded back in the subsequent process. In order to form a shape processing portion such as a perforation in a predetermined portion of a long original fabric, for example, a film cutting device disclosed in Japanese Patent No. 4468934 (device name “almighty special cut (AS cut), General-purpose equipment such as “Rainbow Mechanic Co., Ltd.” etc. can be used. By using such a cutting machine, the shape processing part such as perforations can be made while moving the long raw material of the resin film at high speed. Can be continuously formed at desired positions.

  The long original fabric may be preliminarily printed with colors, patterns, designs, characters, and the like. That is, it is preferable that the manufacturing method of the packaging bag of this invention further has the process of printing on a elongate original fabric. It is also preferable to further include a step of cutting the long original fabric into an appropriate width and length in advance.

  In order to store the objects to be stored in the storage part of the finally obtained packaging bag, as shown in FIG. 7, the objects to be stored 5 are formed on a long original fabric 100 on which a shape processing part such as a perforation 16 is formed. Can be placed. What is necessary is just to make the position which mounts the to-be-contained object 5 into the position enclosed by the elongate original fabric 100 turned back at the subsequent process. In addition, a general-purpose packaging machine can be used in the process after mounting a to-be-contained object on a long original fabric. As a general-purpose packaging machine, for example, Buhrs-Zaandam B.M. V. (The Netherlands "BurrsWrap" series); CMC (Italy) film packaging machines (trade names "CMC2800", "CMC2500", etc.); SITMA (Italy) packaging machines ( Trade names “1005 B-WRAP”, “1050 VARIA WRAP”);

(Process (2))
In step (2), as shown in FIGS. 7 to 9, the long original fabric 100 is folded back so that the formed processed portions such as the perforations 16 overlap at corresponding positions to form folded portions 55 and 65. To do. In addition, in said process (1), when the to-be-contained object 5 is mounted on the long original fabric 100, the long original fabric 100 should just be folded so that the mounted to-be-contained object 5 may be wrapped. Furthermore, as shown in FIG. 9, when the long original fabric 100 is folded, it is preferable that an adhesive material such as a hot melt 75 for sealing is disposed at a predetermined position of the long original fabric 100. By folding the long original fabric 100 in this state, as shown in FIG. 10, at least a part of the opposing surfaces of the long original fabric 100 can be sealed by the sealing portion 18 so that it can be opened. Even if an adhesive material such as hot melt is not used, for example, at least a part of the opposing surfaces of the long original fabric is obtained by heat sealing (thermal fusion) with a predetermined ink interposed therebetween. It can also be sealed so that it can be opened.

(Process (3))
In the step (3), as shown in FIGS. 10 and 11, the long original fabric 100 is sealed and cut at the X and Y positions to form the storage portions 7 for individually storing the objects to be stored 5. More specifically, at the position of X and Y, (i) the long original fabric 100 is thermally welded and then cut, or (ii) the long original fabric 100 is thermally welded at almost the same time. By cutting (tearing) the anti-100, the welded portion 19 is formed. Thereby, the packaging bag 10 provided with the packaging bag main body 12 which consists of a resin film which has the bag-shaped accommodating part 7 in which the to-be-contained object 5 is accommodated can be obtained.

  The packaging bag of the present invention can easily take out the stored item, and can store the taken-out stored item again and take it home from the destination. For this reason, the packaging bag of the present invention is useful as a simple packaging bag that can easily bring back catalogs, pamphlets, magazines, etc. distributed at various exhibitions and concert venues.
