【Example】

(1) Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing the steps of a method for producing a packaging sheet. Packaging sheet 1 produced by this production method
2 is one in which an adhesive 3 having recursiveness in adhesive peeling is applied to two adjacent sides on the back surface of the quadrilateral sheet 2 as shown in FIG. That is, the adhesive 3 is L
It is applied in a letter shape.

The adhesive 3 is styrene / butadiene,
It comprises 20 to 80 parts by weight of at least one elastomeric block copolymer selected from styrene / isobrene and styrene / ethylene-butylene block copolymers and 80 to 20 parts by weight of a tackifying substance.

An arbitrary pattern is printed on the surface of the sheet 2. A product 4 is placed on the packaging sheet 1.

Next, a method for producing a packaging sheet will be described with reference to the process chart shown in FIG.

After the pattern is printed on the surface of the sheet 2 by the rotary printing machine, the sheet 2 is dried in the drying step.

Next, the sheet 2 enters the vertical fold 5 by the triangular plate (former) shown in FIG.

The vertical folding 5 using the triangular plate is a process of folding the sheet 2 at the center of the paper width using the triangular plate.

In the vertical folding 5 using the triangular plate, the inside of the sheet 2 is folded, that is, the back side of the sheet 2,
The nozzles 6a to 6d for the adhesive are arranged. These nozzles 6a to 6d emit the adhesive 3 which has a recursive property for peeling the adhesive.

Of the nozzles 6a to 6d, each nozzle 6
a and 6b are respectively arranged at the edge portions of the sheet 2 and the other nozzles 6c and 6d are movably provided in the width direction of the sheet 2 for a time period corresponding to the feeding speed of the sheet 2. The adhesive 3 is emitted back and forth once in the width direction of the sheet 2 at intervals.

The nozzles 6a to 6d are arranged so that the nozzles 6a and 6b are moved in the width direction of the sheet 2 so as to dispose the nozzles 6c and 6d at the edge portions of the sheet 2 contrary to the above. You may

Therefore, when the sheet 2 enters the vertical fold 4 by the triangular plate, it is bent at the center of the paper width here.

At this time, each of the nozzles 6a and 6b ejects the adhesive 3 to both edge portions of the back surface of the sheet 2 and applies the adhesive 3.

At the same time, the nozzles 6c and 6d reciprocate once in the width direction of the sheet 2 at every time interval according to the feeding speed of the sheet 2, and at this time, the adhesive 3 is ejected to separate the sheet. Apply in the width direction of the sheet 2.

In this way, the sheet 2 is bent and the adhesive 3 is applied. FIG. 4 shows the folded sheet 2 having the back surfaces coated with the adhesive 3 facing each other.

Next, the folded sheet 2 passes through the pulling roller 7 and enters the horizontal cutting (slit) 8. The horizontal trimming 8 is composed of a saw blade cylinder 8a and a cutting cylinder 8b, and is made of the adhesive 3 applied to the sheet 2 at regular intervals, that is, in the lateral direction of the sheet 2 shown in FIG. Cut each edge part.

After that, the folded portion of each sheet 2 is cut by the trimmer 9. Thus, the manufacturing of the packaging sheet 1 shown in FIG. 2 is completed.

Next, a packaging procedure using the packaging sheet 1 will be described.

As shown in FIG. 5 (a), for example, the product 4 is placed on the back surface of the packaging sheet 1, and as shown in FIG. 5 (b), the product 4 is wrapped from the sheet portion to which the adhesive 3 is not applied.

Then, the packaging sheet 1 is sequentially wrapped while being temporarily adhered to the product 4 by the adhesive 3 as shown in FIG. 2 (c), and finally the L-shaped corner portion to which the adhesive 3 is applied is applied. Remains, and this corner portion is the place where the product 4 is finally wrapped.

In this way, when the product 8 is packaged by the packaging sheet 1, since the adhesive 3 is applied in advance, the packaging work can be performed with both hands. Since the adhesive 3 has a recursive property in peeling the adhesive, the aesthetic appearance of the packaging is not good, and even if there is a portion where the once-bonded portion is peeled off and the packaging is performed again, the adhesive strength is not impaired. Moreover, the adhesive 3 is not left on the bonded portion.

However, as a result of being wrapped with the wrapping sheet 1, aesthetically pleasing packaging can be obtained as shown in FIG.

As described above, according to the first embodiment, the adhesive 3 having a recursive adhesive peeling property is formed on the back surface of the sheet 2 to form an L-shape when the sheet 2 is folded.
Since it is applied to the side, and the sheet 2 having the adhesive 3 applied thereto is placed inside, the sheet 2 is bent and cut.
It is possible to create the packaging sheet 1 which can be easily aesthetically wrapped by using both hands and can reduce the burden.

Further, according to such a manufacturing method, since the surfaces coated with the adhesive 3 are aligned and folded, the packaging sheets 1 are not adhered unnecessarily.

Further, since the adhesive 3 is applied to the back surface of the packaging sheet 1, when the packaging sheets 1 themselves are superposed and stored, the packaging sheets 1 are adhered to each other so that they do not come apart.

Further, since the side to which the adhesive 3 is not applied is left, the distortion due to the expansion of the packaging sheet is concentrated on the side to which the adhesive 3 is not applied even if the moisture in the air is absorbed. The distortion can be reduced as a whole. In particular, when the adhesive 3 is applied to all four sides of the sheet 2, the sheet 2
Although there is a possibility that the strain will be concentrated in the central part of the wrinkles and wrinkles will occur, such wrinkles can be prevented because the side where the adhesive 3 is not applied remains.

(2) Next, a second embodiment of the present invention will be described.

FIG. 6 (a) is a diagram showing the packaging sheet and the packaging procedure. The packaging sheet 20 is formed by applying an adhesive 22 having a recursive adhesive peeling property similar to the above to the U-shaped three sides on the back surface of a quadrilateral sheet 21. An arbitrary pattern is printed on the surface of the sheet 21.

Next, a method of manufacturing the packaging sheet will be described with reference to FIG. The manufacturing process is almost the same as that of the first embodiment, and only different points will be described.

Of the nozzles 6a to 6d, the nozzles 6a,
6b are respectively arranged at the edge portions of the single sheet 21, and the nozzles 6c and 6d are movably provided in the width direction of the single sheet 21 at a time interval corresponding to the feeding speed of the single sheet 21. The adhesive 22 is emitted back and forth once in the width direction of the sheet 21.

In this case, the nozzles 6c and 6d have the width for applying the adhesive 22 approximately twice the width for applying the adhesive 22 in the above embodiment.

In the nozzles 6a to 6d, the nozzles 6a and 6b are moved in the width direction of the sheet 21 in the same manner as described above, and the nozzles 6c and 6d are arranged at the edge portions of the sheet 21. May be.

Further, the horizontal cut 8 is cut at the central portion of the adhesive 22 applied in the width direction of the sheet 21.

In this manufacturing process, when the printed and dried sheet 21 enters the vertical folding 5 by the triangular plate, it is bent at the center of the sheet width.

At this time, the nozzles 6a and 6b eject and apply the adhesive 22 to both edge portions of the sheet 21, and the nozzles 6c and 6d also feed the sheet 21 at the same time. The sheet 22 is reciprocated once in the width direction of the sheet 21 at every time interval according to, and at this time, the adhesive 22 is ejected and applied in the width direction of the sheet 21.

After this, the folded sheet 21
In the horizontal cutting 8, the sheet 2 is cut at regular intervals, that is, the central portion of the adhesive 22 applied in the lateral direction of the sheet 21 shown in FIG.

After that, the folded portion of each sheet 21 is cut by the trimmer 9. Thus, FIG.
The manufacturing of the packaging sheet 20 shown in (a) is completed.

Next, a packaging procedure using the packaging sheet 20 will be described.

The product 4 is placed on the back surface of the packaging sheet 20 as shown in FIG. 4 (a), and the product 4 is packaged as shown in FIG. 4 (b). In this case, the packaging is performed so as to wrap the caramel.

By this packaging, the U-shaped portion to which the adhesive 22 is applied remains, and this portion is the portion where the product 4 is finally wrapped.

In this way, when the product 4 is packaged by the packaging sheet 20, since the adhesive 22 is applied in advance as in the first embodiment, the packaging work can be performed with both hands. Since the adhesive 22 has a recursive property for peeling the adhesive, even if the aesthetic appearance of the packaging is poor and there is a portion where the once-bonded portion is peeled off and the packaging is redone, the adhesive force is not impaired. Moreover, the adhesive 22 is not left on the bonded portion.

However, as a result of being wrapped with the wrapping sheet 20, a aesthetically pleasing wrap can be obtained as shown in FIG.

As described above, according to the second embodiment, the adhesive 22 having the recursive adhesive peeling property is formed on the back surface of the sheet 21 when the sheet 21 is bent. Sheet-side sheet 2 that is applied to the sides and the surface side is the inside
Since 1 is bent and cut, the work load of the packaging can be reduced by an easy work using both hands, and the packaging can be done with a good appearance, and so-called caramel packaging can be performed.

Since the side to which the adhesive 22 is not applied is left, it is possible to prevent wrinkles when absorbing moisture in the air.

(3) Next, a third embodiment of the present invention will be described.

FIG. 7 is a diagram showing a packaging sheet. The packaging sheet 30 is formed by applying an adhesive 32 having recursive adhesive peeling similar to the above to each corner portion on the back surface of a quadrilateral sheet 31. An arbitrary pattern is printed on the surface of the sheet 31.

Next, a method of manufacturing the packaging sheet will be described with reference to FIG. The manufacturing process is almost the same as that of the first embodiment, and only different points will be described.

Of the nozzles 6a to 6d, the nozzles 6a,
6b are arranged at the edge portions of the sheet 31 and emit the adhesive 32 at a predetermined interval. The nozzles 6c and 6d are arranged at the bent portion of the sheet 31 and are arranged at the nozzles 6a, 6b. Adhesive 3 at the same timing as 6b
2 is emitted.

Therefore, in the horizontal cutting 8, each adhesive 32
The packaging sheet 30 is manufactured by cutting the coated portion at the central portion.

With such a packaging sheet 30, for example, when a product is packaged, the product is sequentially wrapped while being temporarily adhered by the corner portion to which the adhesive 32 is applied. The applied corners are adhered to complete the packaging.

Therefore, the packaging work can be performed with both hands, and even if the aesthetic appearance of the packaging is unsatisfactory and there is a portion where the once-bonded portion is peeled off and the packaging is performed again, the adhesive strength is not impaired.
In addition, the adhesive 32 is not left on the adhered portion, and packaging can be performed with a good appearance.

Further, since the side to which the adhesive 32 is not applied is left, it is possible to prevent wrinkles when absorbing moisture in the air.

(4) Next, a fourth embodiment of the present invention will be described.

FIG. 8 is a diagram showing a packaging sheet. This wrapping sheet 40 is obtained by applying an adhesive 42 having a recursive adhesive peeling property to the other corner portion of each of the corner portions on the back surface of the quadrilateral sheet 41, which leaves one corner portion. is there. An arbitrary pattern is printed on the surface of the sheet 41.

Even with such a wrapping sheet 40, the wrapping work can be performed with both hands as in the case of the third embodiment. Even if the aesthetic appearance of the wrapping is unsatisfactory, there is a portion where the part which is once adhered is peeled off and the wrapping is redone. Even if the adhesive strength is not impaired and the adhesive 3 is not left on the adhered portion, the packaging can be performed with a good appearance.

Further, since the corner portion to which the adhesive agent 42 is not applied is left, when the packaging sheet 40 is unwound, it becomes easy to peel it from the corner portion to which the adhesive agent 42 is not applied.

(5) The present invention is not limited to the above-mentioned embodiments, but may be modified within the scope of the invention.

For example, in each of the above-mentioned embodiments, the sheet is bent by the vertical folding 5 by the triangular plate, and the adhesives having recursive adhesive peeling property are applied by the nozzles 6a to 6d. Although 2 is cut, it is also possible to use a saw blade cylinder 8a as a horizontal cut and a cutting cylinder 8b also serving as a folding cylinder, and cut the single sheet in this horizontal cut and bend the single sheet. Good.

Further, the flow route of the sheet is such that the sheet is cut and bent by the horizontal cutting using the saw blade cylinder 8a and the cutting cylinder 8b also serving as the folding cylinder, and then the sheet is cut at right angles. The flow direction may be changed to, and thereafter, the folded portion of the sheet may be cut by a trimmer.

Further, by applying an adhesive having a recursive adhesive peeling property to each required portion on the front and back sides of the sheet, the work of packaging the product or the like can be further simplified, and the adhesiveness when the packaging is completed is improved.
