Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a packaging bag that is used, for example, for individually packaging baked goods such as cookies and can be easily opened without damaging the shape of the contents.

[0002]

[Prior art]

 Conventionally, as a form of this type of packaging bag, a so-called pillow package in which a palm-sealing seal is provided only on one side in the longitudinal direction and upper and lower seals are provided in the direction perpendicular to the palm-sealing surface is generally used. ing.

In order to be able to tear a line neatly and cleanly, conventionally, a film having easy tearability in a specific direction (-axially stretched film) is used to enhance the tearability of the packaging material. At the same time, it is known that notches or the like are provided on the edge of the bag.

[0004]

[Problems to be solved by the device]

 Conventionally, when packaging fragile items such as baked confectionery using pillow packaging, the contents are caught and difficult to open even if they are torn from the upper and lower notches to wrap relatively tightly, and the shape of the contents when opened. However, when the uniaxially stretched film is used, the cost becomes high.

There is also a method of pulling and opening the pouch seal and the bag on the opposite side by pulling, but when the bag is tightly packed, the bag side cannot be pinched and the bag is forcibly pinched. Then, there is also a problem that the shape of the contents is damaged.

The present invention has been made in view of the above problems, in which the cost is increased and the contents can be extremely easily opened without damaging the contents, and the opened portion can be opened greatly. The purpose is to provide a packaging bag capable of

[0007]

[Means for Solving the Problems]

 The gist of the present invention for achieving the above object is characterized in that a fold-shaped seal portion that can be picked up and pulled is also provided at a position on the opposite side of the packing bag seal on the opposite side. To do.

The wrinkle-shaped seal portion does not have to be the entire surface from the upper end to the lower end, and the length of the seal portion should be the seal width of the upper and lower ends or the width of the chisel seal. 2 to 3 times that of

Further, since the film is continuous in terms of the seal strength of the folds, if the seals at the upper and lower ends are completely performed, even if the seal strength at other portions is weak, it is necessary to pick it up. It should be adhered to the extent that folds can be formed.

[0010]

[Action]

 In the packaging bag with the above structure, since there are two protrusions necessary for opening, the force acts only in the horizontal direction and peels off easily. Also, since the pulling direction is only in the horizontal plane, no force is applied to the contents storage part, so the contents Will not be damaged.

[0011]

【Example】

 Embodiments will be described below with reference to the drawings.

FIG. 1 is a schematic perspective view showing a packaging bag 1 according to an embodiment of the present invention, FIG. 2 is a sectional view taken along the line II, and FIG. 3 is a sectional view taken along the line II-II.

The packaging bag 1 is composed of a laminated body 2 in which a CPP film is dry laminated on the innermost layer, and includes an upper seal 3, a lower seal 6, a central gas seal seal 4, and a fold-shaped seal. It is equipped with a rule part 5.

The upper and lower seals 3 and 6 are positioned vertically to the central gas palm seal 4, and the gas palm seal 4 functions as a back seal and is provided on the opposite side of the gas palm seal 4. A fold-shaped seal 5 for opening and picking is formed.

The laminated body 2 constitutes the packaging bag 1 in a direction parallel to the gas palm seal 4, that is, in the direction of arrow AA. In the figure, 7 is the contents contained in the packaging bag 1.

Examples of the structure of the laminate (2) used include OPP (20 μm) / printing / adhesive / CPP (20 μm) PET (12 μm) / printing / adhesive / CPP (20 μm). .

The above embodiment is an embodiment in which the present invention is applied to a pillow bag, and only the upper and lower ends are provided with fold-like seals. However, as shown in FIG. 5, they may be sealed on the entire surface. Although not shown, it is needless to say that the width may be up to 2 to 3 times the width of the seal. However, depending on the shape of the packaging bag, it is preferable to install it at the upper and lower ends depending on the shape of the packaging bag.The present invention is not limited to this, and it may be installed on any bag having a chisel seal, for example, a gusset bag. Is also applicable.

[0018]

[Effect of device]

 As described above, in the present invention, since the palm-sealing portion is formed on the opposite side of the longitudinal palm-sealing seal, the palm-sealing seals on both sides are pinched so that the ceiling-sealing surface can be positioned horizontally. By pulling and opening, it has an effect that it can be opened very easily without interfering with the contents, and the opening part can be opened greatly.
