  Hereinafter, the present invention will be described in detail. The description of the constituent elements described below may be made based on representative embodiments and specific examples, but the present invention is not limited to such embodiments. In order to express the contents of the present invention, embodiments of the present invention may be described with reference to the drawings. However, the present invention is not limited to the embodiments of the drawings, and the present specification. The present invention includes modifications and improvements obvious to those skilled in the art based on the matters described in (1).

(Packaging bag)
The present invention relates to a packaging bag for accommodating an object to be packed. The packaging bag of the present invention includes a bag-shaped main body film that accommodates an object to be packed, and a band-shaped handle film that straddles the upper surface of the main body film and has both end portions joined to both side surfaces of the main body film, respectively. It is. Here, when the grip film of the packaging bag is joined to the main body film and pulled upward using a Tensilon tensile tester, the Tensilon tensile breaking strength satisfies the following formula.
y> 0.1x + 30
In the above formula, x is the total weight (g) of the packaging object, the main body film, and the handle film, and x is 1200 or more. Y represents Tensilon tensile strength at break (N).

  Since the packaging bag of this invention has the said structure, it has the outstanding vibration durability. For this reason, in this invention, even if it is a case where it grips the grip film of the package which has a weight of 1200 g or more and walks for a long time, the main body film is broken or the grip film is detached from the main body film. Will not occur. As described above, the packaging bag of the present invention is particularly suitable for an application for packaging a heavy packing object.

  In addition, in this specification, the whole packaging bag which accommodated the packing target object is called a package. That is, the packaging body is composed of a packaging object and a packaging bag. FIG. 1 illustrates a package, and illustrates a packaging bag 100 in a state in which a plurality of toilet rolls (packaging objects 5) are accommodated. As shown in FIG. 1, the packaging bag 100 includes a main body film 10 and a handle film 20, and both end portions of the handle film 20 are respectively joined to both side surfaces of the main body film 10. The handle film 20 preferably has an adhesive portion 30, and the main body film 10 and the handle film 20 are joined by bonding the adhesive portion 30 to the main body film 10. In addition, the both ends of the handle film 20 and the main body film 10 may be joined by heat sealing. In this case, the handle film 20 may not have the adhesive part 30, and the heat seal part becomes the adhesive part 30.

  The upper surface of the main body film refers to a surface located on the upper surface (top surface) when the packaging object 5 is accommodated in the packaging bag 100, and a surface facing the upper surface is referred to as a lower surface (bottom surface). The upper surface is a surface indicated by 10a in FIG. 1, and the lower surface is a surface indicated by 10b. Further, the side surface of the main body film is a surface connecting the upper surface and the lower surface.

  Both end portions of the handle film 20 are respectively joined to both side surfaces of the main body film 10. Both end portions of the handle film 20 are respectively joined to opposite side surfaces of the main body film 10 across the upper surface of the main body film 10. In addition, when the planar shape of an upper surface is a shape which has a major axis direction and a minor-axis direction, it is preferable that the handle film 20 is arrange | positioned along a major-axis direction.

  The packaging bag 100 can accommodate not only toilet rolls, but also rolls of kitchen paper (kitchen rolls), sanitary paper stored in boxes, disposable diapers, and the like. In the present specification, an article that can be accommodated in the packaging bag 100 is referred to as a “packaging object”.

  About a toilet roll, it may be calculated | required to lengthen winding length and to increase the effective usage per piece. Long roll toilet rolls with a roll length of 2 or 3 times that of normal toilet rolls have been commercialized. In such a case, the weight per toilet roll is increased, and the weight of the entire packing object is also significantly increased compared to the conventional product. For example, the weight per toilet roll may be 150 g or more, or 200 g or more. In the packaging bag 100 of the present invention, when the handle film is pulled upward, Tensilon tensile breaking strength satisfies a predetermined condition. Can be carried around. For this reason, the packaging bag of this invention can also be called the packaging bag for a long roll toilet roll accommodation.

When the handle film of the packaging bag is joined to the main body film and pulled upward using a Tensilon tensile tester, the Tensilon tensile breaking strength satisfies the following formula.
y> 0.1x + 30
In the above formula, x is the total weight (g) of the packaging object, the main body film, and the handle film, and x is 1200 or more. Y represents Tensilon tensile strength at break (N).
y may be a value larger than 0.1x + 30, but is preferably a value larger than 0.1x + 35, and more preferably a value larger than 0.1x + 40. By controlling the value of y within a range that satisfies the above conditions, the vibration durability of the packaging bag can be increased. For this reason, even if it grips the handle film of the packaging bag which packed the packing object which has a weight of 1200 g or more, and walks for a long time, the main body film is broken or the handle film is detached from the main body film, etc. The problem does not occur. Note that the above conditional expression indicates a condition under which effects such as vibration durability can be obtained particularly when x is 1200 or more. The upper limit value of x is not particularly limited, but can be set to 6000, for example.

  FIG. 2 is a graph showing the relationship between the total weight (g) of the object to be packed, the main body film and the handle film (packaging body) and the Tensilon tensile breaking strength (N) when the handle film is pulled upward. The present invention has found a preferable condition of Tensilon tensile breaking strength (N) when a handle film is pulled upward when a packaging object having a large weight is accommodated.

  Tensilon tensile breaking strength when the handle film is pulled upward is measured by the following method. First, an L-shaped jig (L-shaped long side length 9 cm, width 7 cm, as shown in FIG. 3) is attached to the top chuck of the Tensilon tensile tester (manufactured by A & D). Install L-shaped short side length 3cm). At this time, the long side member of the L-shaped jig is attached to the upper chuck so that the distance from the top of the L-shaped jig long side to the lower end of the upper chuck is 40 mm. Next, an L-shaped jig is hooked on the central portion in the longitudinal direction of the grip film of the packaging bag. Then, press the start button of the Tensilon tensile tester while holding both sides of the package (under the adhesive part of the handle film) by hand, and pull it upward at a speed of 500 mm / min until the handle film breaks. . The tensile strength when the handle film is broken is defined as Tensilon tensile strength.

  In the packaging bag of the present invention, the main body film preferably accommodates toilet rolls so that there are two rows in the horizontal direction and two or more steps in the vertical direction, two rows in the horizontal direction and three steps in the vertical direction. It is more preferable that the container is accommodated as described above. That is, the packaging bag of the present invention accommodates at least 4 toilet rolls, and preferably accommodates 6 toilet rolls. In addition, the packaging bag of this invention may accommodate eight toilet rolls.

  The packaging bag of the present invention preferably packs toilet rolls arranged in two rows in the horizontal direction. FIG. 4 is a top view of a packaging bag packed with toilet rolls arranged in two rows in the horizontal direction. FIG. 4 shows a top view of the main body film, and is a top view in a state where the handle film is removed. As shown in FIG. 4, when the packaging bag is for packing toilet rolls arranged in two rows in the horizontal direction, a major axis P and a minor axis Q exist on the upper surface. In the present invention, the handle film 20 is preferably provided along the major axis direction of the upper surface of the main body film. That is, it is preferable to join the handle film 20 to the main body film 10 so that the long axis P and the center line in the longitudinal direction of the handle film 20 overlap. Thereby, the ease of carrying a package can be improved and the vibration durability of a packaging bag can be improved.

  Both end portions of the handle film 20 are respectively joined to both side surfaces of the main body film 10. It is preferable that the adhesion part 30 is provided in the both ends of the handle film 20, and the main body film 10 and the handle film 20 are joined by adhering such an adhesion part 30 to the main body film 10.

  FIG. 5 is a diagram illustrating the configuration of the handle film. As shown in FIG. 5, the handle film 20 is a belt-like film and is preferably composed of an adhesive tape 22 and a resin film 24. FIG. 5A is a cross-sectional view in the thickness direction of the handle film 20. As shown in FIG. 5A, in the handle film 20, the length of the adhesive tape 22 is longer than that of the resin film 24. And the resin film 24 is stuck to the center area | region except the both ends of the adhesive tape 22. FIG. FIG. 5B is a plan view of the handle film 20 as viewed from the resin film 24 side. As can be seen from FIG. 5B, since the resin film 24 is attached to the central region excluding both ends of the adhesive tape 22, the adhesive surface of the adhesive tape 22 is exposed at both ends. The adhesive surface exposed in this way becomes the adhesive portion 30, and the main body film 10 and the handle film 20 are joined by the adhesive portions 30 being bonded to the main body film 10.

  In FIG.5 (b), the length of the adhesion part 30 is represented by a, and the width | variety of the adhesion part 30 is represented by b. a is preferably 46 mm or more, and more preferably 50 mm or more. a is preferably 120 mm or less, more preferably 100 mm or less, and still more preferably 80 mm or less.

The width of the bonding portion 30 and the width of the handle portion 35 may be the same or different. For example, a mode in which the width of the bonding portion 30 is larger than the width of the handle portion 35 is also a preferable mode. In this case, the main body film 10 and the handle film 20 can be firmly bonded at the bonding portion 30, while the handle portion 35 has a shape that can be easily gripped with fingers. Thereby, both vibration durability and ease of carrying can be achieved.

  The length of the handle film 20 is preferably 15 cm or more, and more preferably 20 cm or more. The length of the handle portion 35 of the handle film 20 is preferably equal to the length of the major axis on the upper surface of the packaging bag, even if the length of the major axis on the upper surface of the packaging bag is 5% or more. The length of the long axis on the upper surface of the packaging bag may be + 10% or more. By setting the length of the handle portion 35 to the above condition, it becomes easy to hook a finger when carrying it, and the ease of carrying can be further enhanced. In addition, the said conditions are conditions when the upper end of the adhesion part 30 and the upper end of the side surface of the main body film 10 are the same height. When the upper end of the bonding part 30 is lower than the upper end of the side surface of the main body film 10, the length of the handle film 20 may be the length of the long axis of the upper surface of the packaging bag + 20% or more. .

At this time, the long side member of the L-shaped jig was attached to the upper chuck so that the distance from the top of the long side of the L-shaped jig to the lower end of the upper chuck was 40 mm. An L-shaped jig was hooked on the center in the longitudinal direction of the grip film of the packaging bag obtained in the examples and comparative examples. Then, press the start button of the Tensilon Tensile Tester while holding both sides of the package (under the adhesive part of the handle film) with your hand, and move upward at a speed of 500 mm / min until the handle film breaks from the main body film. Pulled up. The tensile strength when the handle film broke from the main body film was recorded as Tensilon tensile breaking strength.

<Number of vibrations and vibration durability>
From the state where the arm was extended and the handle film was firmly grasped, the package was lifted 20 cm ± 5 cm vertically upward, and the operation of quickly extending the arm was repeated. When the arm was quickly extended, the package naturally dropped, and when the arm extended, the grip film was used to receive the impact of the drop. The operation of lifting and lowering vertically upward was counted as one vibration frequency, and such an operation was performed at a speed of 15 ± 1/10 seconds. The above operation was repeated continuously until the handle film was broken, and the number of times when the handle film was broken was recorded in the item of vibration frequency in Table 1. The vibration durability was evaluated according to the following criteria.
(Double-circle): Even if it is a case where the frequency | count of vibration is 100 times, a handle film does not fracture | rupture from a main body film (it is a level which does not have a problem at all even for long walk conveyance and running conveyance).
○: The grip film breaks from the main body film when the number of vibrations is 50 times or more and less than 100 times (a level at which there is no problem in normal walking conveyance).
X: The handle film breaks from the main body film when the number of vibrations is 1 or more and less than 50 (a level at which there is a problem in normal walking conveyance).

  As can be seen from Table 1, in the examples, sufficient vibration durability was exhibited even when the weight of the package was 1200 g or more.
