〔Example〕

Hereinafter, the present invention will be described in more detail with reference to the embodiments of the present invention shown in the drawings.

FIG. 1 shows a packaging material 11 according to an embodiment of the invention described in claim 1.
FIG. 2 is a schematic plan view of FIG. Packaging material
11 has a rectangular flat bag 12, and this bag 12 is
One exterior film 13 forming one surface and two interior films 14, 14 forming the opposite surface are overlapped,
It is formed by bonding the peripheral edge. Code 15
Indicates a peripheral adhesive portion, that is, a seal portion. At the center of the exterior film 13 forming one surface of the bag 12, a tear tape 16 is provided to form an opening portion that can be easily opened. Instead of the tear tape 16, perforations or the like may be formed and used as the unsealed portion. The interior films 14, 14 forming the opposite surface of the bag 12 are arranged so that the slits 17 are formed at the positions overlapping the tailor tape 16.

A peeling film 18 is attached to the outer surfaces of the inner films 14, 14. This peeling film 18 has a perforation 19 for tearing in the center, and the perforation 19
Both sides of the inner film 14 are adhered to the edges of the interior films 14, 14 located on both sides of the slit 17, respectively. Reference numeral 20 indicates this adhesive portion or seal portion.

In the present embodiment, a plate glue 21 is placed in the bag 12 as a contained item.

Next, a method of using the packaging material 11 having the above configuration will be described. Third
As shown in FIG. 4 and FIG. 4, the packaging material 11 is attached so that the peeling film 18 side is inside and sandwiches the rice ball 22 which is the object to be packaged. As shown in FIG. Wrap the rice ball by folding it forward.

Here, the bag 12 has a slit 17 on one surface,
Since the peeling film 18 covers it, the packaging material 11
It is extremely hygienic because no foreign matter enters inside the rice ball after it is made and before the rice ball is wrapped with the packaging material 11. Also, the moisture of the rice ball will not get inside even after the rice ball is wrapped. Note that the peeling film 18 has perforations 19, but since the opening is extremely small, there is no problem.

Next, when opening the packaging material 11, the packaging material 11 is shown in FIG.
Return to the state shown in FIG.
The center of the exterior film 13 is cut off. As a result, the sixth
It becomes the state of the figure. Next, while holding one side of the packaging material 11 pressed against a rice ball, the end portion 11a on the opposite side of the bag 12 is held and pulled in the direction of the arrow. As a result, the peeling film 18 is torn at the perforations 19. Then, as shown in FIG. 7, the peeling film that was in contact with the rice ball 22.
18 is removed from the center and removed. By this,
The plate paste 21 is exposed and wrapped around the rice ball 22. Then, by pulling the packaging material 11 on the opposite side, the packaging material 11 is also removed. Thus, the whole plate paste 21 is a rice ball
Can be wrapped around 22. The opening operation may be performed with the packaging material 11 in the packaging state shown in FIG.

Exterior film 13 and interior film 1 used for the packaging material 11
4. The material of the peeling film 18 and the like is not particularly limited, but a resin single layer film or a laminated film is usually used. Since the peelable film 18 is peeled from the rice ball 22 and slides with respect to the interior film 14 when opened, it is preferable to use a film having good peelability and slipperiness. Also, the inner film 14 and the outer film 13
Since it is necessary to slide on the inner plate glue 21 at the time of opening, it is preferable to use a film having good sliding property. Exterior film 13, interior film 14, peeling film 18
Embossing may be applied to the parts to improve the slip. Since the exterior film 13 is the surface that becomes the outer surface when the rice balls are wrapped, it may be printed, and it is preferable to use a film with good printability. The seal portions 15 and 20 may be formed by heat sealing, a sheet made of an adhesive, or the like.
The use of heat sealing is preferable because it is easy to manufacture. Considering these, as an example of a suitable combination of each film, the peeling film 18 is HDPE or OPP having a sealing property, and the interior film 14 is an OPP (or C having a sealing property).
PP), OPP (or CP) whose exterior film 13 has sealing properties
P), or the peeling film 18 and the interior film 14 are HDPE, and the exterior film 13 is the inner surface (interior film 1).
Examples include a combination of a PET and PE laminated film having a PE layer on the side 4). The peeling film 18
As described above, since it tears when opened, it is preferable that it can be easily torn, and it is preferable to use a uniaxially stretched film. If a uniaxially stretched film is used, the number of perforations in the perforations 19 can be reduced.

The packaging material 11 having the above structure can be easily manufactured from a continuous long film. That is, while running a continuous interior film, a slit is formed by cutting at the center, a continuous peeling film is overlaid on it to seal at a predetermined position, and a perforation process is performed at the center of the peeling film. A continuous exterior film with a tear tape attached is overlaid on the interior film, and board glue is supplied between the exterior film and the interior film.
Seal the side edges of the laminated exterior film and interior film,
Moreover, the packaging material 11 shown in FIG. 1 is formed by laterally sealing with a constant feeling and cutting the center of the sealing portion.
Can be manufactured. At this time, when the exterior film and the interior film are laterally sealed, for example, when heat sealing is used, a peeling film 18 is formed on the interior film 14 as can be seen from FIGS. 1 and 2. Therefore, the portions 18a at both ends of the peeling film 18 are the inner film 1
It may adhere to 4. Since the end portion 18a of the peeling film 18 hardly contacts the rice ball 21, there is no problem even if the end portion 18a is adhered to the interior film 14.
If there is a problem, a slit may be formed along the end 18a. In addition, the manufacturing method is changed so that a peeling film having a short length is attached to the interior film, and when the interior film and the exterior film are heat-sealed in the lateral direction, both ends of the peeling film are prevented from coming into contact with the heat-sealing position. May be.

In the above embodiment, the bag 12 is composed of the exterior film 13 and the two interior films 14, 14, but the bag 12 may be composed of one film instead. FIG. 8 is a sectional view similar to FIG. 2 showing an embodiment in that case. In the packaging material 11A of this embodiment, one film 24 is folded so that both ends are close to each other to form a bag 12A, and a slit 17 is formed between the both ends close to each other. Then, a peeling film 18 having a perforation 19 in the center is provided on the outer side of the seal portions 20, 2
It is attached by bonding with 0. In addition, it is preferable that seal portions 25 are formed at both ends of the bag 12A so that the plate glue 21 contained therein does not move. Other configurations are shown in FIG.
This is similar to the embodiment shown in FIG. This packaging material 11A is also the first
It is used in the same manner as the packaging material 11 shown in FIGS.

FIG. 9 shows a packaging material 11 according to an embodiment of the invention as set forth in claim 2.

A peeling film 18 is attached to the outside of the interior films 14, 14. However, this release film 18
Is not directly sealed to the outer surfaces of the interior films 14, 14, but is adhered to the interior films 14, 14 by an adhesive film 27 arranged inside the slits 17 of the interior films 14, 14. That is, the adhesive film 27 is adhered to the peeling film 18 at the seal portion 28, and is adhered to the interior films 14 and 14 at the seal portions 29 and 29, respectively. The seal portions 28 and 29 may also be heat seal, seal by an adhesive, or the like. Furthermore, the peeling film 18 and the adhesive film 27
At the center of the seal portion 28, tearing perforations 19, 30 are formed. Other configurations are the same as those of the packaging material of FIGS. 1 and 2.

This packaging material 11B is also used in the same manner as the packaging material 11 shown in FIGS. At the time of opening, after the center of the exterior film 13 is cut off by the tear tape 16 and the end of the packaging material 11B is pulled, the peeling film 18 and the adhesive film 27 are both torn by the perforations 19, 30. Since the interior films 14 are connected to the peeling film 18 by the adhesive films 27 on both sides of the cut position, the peeling film 18 can be peeled from the rice ball.

The embodiment shown in FIG. 9 is an inner film 14 outer surface and a peeling film.
It is suitable when it is difficult to seal 18 and. For example, when a laminated film having heat sealability only on the exterior film 13 side is used as the interior film 14, even if the peeling film 18 has heat sealability, the interior film 14
It is difficult to heat seal the outer surface of the film directly to the peeling film 18. In that case, however, if the heat-sealable adhesive film 27 is pressed against the inner surface of the film, the adhesive film 27 can be heat-sealed to both the interior film 14 and the peeling film 18. It is possible to connect the peeling film 18. It is preferable to use a uniaxially stretched film also for the adhesive film 27 used here so that it can be easily torn.

Also in the packaging material 11B shown in FIG. 9, the bag 12B can be modified so as to be composed of one film as in the embodiment shown in FIG.
