Abstract

PROBLEM TO BE SOLVED: To provide a packaging bag of the hutt seam type wherein a back-lining seal has effects in terms of design and a back-lining part is enlarged and widened, and angles at a back-lining position are changed to enable a three- dimensional design. SOLUTION: In the packaging bag of the hutt seam type, wherein the opposite end edges of one film are back-pasted to each other to paste and seal the upper and lower ends of the film, the width (a) of a back-lining seal (11) is set to a length equal to or longer than the length (b) from a back-lining (10) seal folding back line (14) to one of folding lines (15).

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging bag having a display effect and made of a soft packaging material such as plastic film and paper.

[0002]

2. Description of the Related Art Conventionally, a gasket-type packaging bag, which is made of a soft packaging material such as plastic film or paper, is formed by pasting both sides of one film on the back and adhesively sealing the upper and lower ends. Have been.

[0003] The back sticker of the packaging bag of the double-sided sticking type is provided with a function of easy opening as disclosed in Japanese Utility Model Application Laid-Open No. 4-74639, for example, or Japanese Unexamined Patent Publication No. It has a function of a steam passage as disclosed in Japanese Patent Publication No. 121249,
There was no packaging bag in which the function of design was added to the backside sticker of the packaging bag of the joint palm type.

[0004]

SUMMARY OF THE INVENTION The present invention provides a three-dimensional seal by providing a design function to a back sticker of a packaging bag of a double-sided sticking type, making the back stick part wider and wider, and changing the position of the back stick. It is an object of the present invention to provide a packaging bag that can be designed and put on a palm.

[0005]

According to a first aspect of the present invention, there is provided a packaging bag of a single-armed type comprising a film, wherein both side edges of the film are attached to the back, and upper and lower ends are adhesively sealed. The width of the back pasting seal is set to be equal to or longer than the length from the back pasting seal folding line to one of the folding lines of the packaging bag.

As described above, the width of the backing seal is set to be equal to or longer than the length from the folding line of the backing seal to one of the folding lines of the packaging bag. When the back sticker is set up, the back sticker can show a planar design in a three-dimensional manner.

According to a second aspect of the present invention, in the first aspect of the present invention, the length from the back-sealing folded line to one of the folding lines of the packaging bag is from the back-sealing folded line to the other side of the packaging bag. A packaging bag having a display effect, wherein the packaging bag is set to be shorter than the length up to the bending line.

As described above, the length from the back-sealing seal folding line to one folding line of the packaging bag is set shorter than the length from the back-sealing sealing folding line to the other folding line of the packaging bag. So, if you start the back sticker, the back sticker will not be buried in the packaging bag,
It can show more three-dimensional, and the display effect is further improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a packaging bag having a display effect according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective explanatory view schematically showing a packaging bag having a display effect according to the present invention, and FIG.
FIG. 4 is a cross-sectional explanatory view taken along line A ′. The packaging bag having a display effect according to the present invention is formed by bonding both sides of one film with a back sticker (11) and bonding the upper and lower ends by an upper seal (12) and a lower seal (13). It is a packaging bag (10) of a pasting type.

Upper seal (12) and lower seal (13)
Is positioned perpendicular to the back sticker (11), and the back sticker (11) is made wider than the conventional back sticker.

That is, the width (a) of the backing seal (11) is equal to the length (b) from the backing seal folding line (14) to one folding line (15) of the packaging bag.
Or it is set long.

Further, the length (b) from the back adhesive seal folding line (14) to one folding line (15) of the packaging bag.
Is set shorter than the length (c) from the back-sealing seal folding line (14) to the other folding line (16) of the packaging bag.

In other words, if more specific numerical values are used, the width (a) of the back sticker is generally 10 m.
m is expanded to about 50 mm, and the back sticker is provided not at the center but at a position closer to one of the bending lines. By designing the backside sticker surface and starting up the backside sticker, it is possible to make the design look three-dimensional.

The film to be used needs to have a heat-sealing inner surface, and a laminated film can be preferably used. For example, biaxially oriented polypropylene (OPP) film (20 μm) / adhesive / printing layer / unoriented polypropylene (CPP) film (20 μm),
Polyethylene terephthalate (PET) film (12
μm) / adhesive / printing layer / CPP film (20 μm)
And the like.

[0016]

As described above, the packaging bag of the present invention has a surface with the backing seal on the front side, and the width of the sealing is widened by shifting the backing seal from the center to one side.
In design development, it is possible to make the design wider and wider by the width of the seal. Also, by raising the back sticker, it is possible to have a view from the side of a design that was normally seen only on a flat surface, and it is possible to make the design look three-dimensional. Further, since the work can be performed with a vertical or horizontal pillow type automatic packaging and filling machine, workability equivalent to that of a conventional packaging bag can be obtained.
