Description

[Detailed description of the invention] (Industrial application field) This invention relates to a printed / printed material bonding structure that can be used for direct mail, advertisement leaflets, and the like.

(Prior art) Conventionally, for various communications such as direct mail or bank transfer notices, papers etc. are releasably adhered to each other so that notices etc. can be sent confidentially.
Printed materials are often used.

Conventionally, in this type of bonding structure, the paper is bonded with a peelable adhesive seal interposed therebetween, and the paper in which a heat sealant has been previously inserted is heated and peelably bonded. , An opaque sticker that can be peeled off on half of the paper,
There is a paper in which the periphery or three sides of the paper are adhered with a pressure adhesive, a heat sealant or another adhesive, and the adhesive surface is cut off and opened.

(Problem to be Solved by the Invention) However, in the above-mentioned conventional bonding structure, since an adhesive seal or an adhesive seal is used, not only the printed / printed material becomes expensive, but also the seal There is a problem that printing / printing is impossible.

In addition, in the above-described conventional bonding structure, since a sheet into which a heat sealant is inserted is used, when, for example, solid printing of any number of colors is performed on the paper surface and the ink layer film becomes thick, the temperature becomes about 180 ° C. If heat sealing is not performed at a high temperature, the sealant of the paper will not act sufficiently and may not be adhered.On the other hand, if the heat sealing is performed at such a high temperature, the printing surface will deteriorate, and the toner of the printer will melt at 90 ° C or higher. There was a problem of doing it.

Further, in the above-described conventional bonding structure, since the adhesive surface is cut off and opened, it is necessary to previously perforate the paper.

On the other hand, the present inventor, before or after printing / printing,
A peelable low-temperature adhesive heat-sealant is applied to the overlapping surface of the paper, and the paper is releasably adhered by heat sealing, so that there is no restriction on printing and printing, and it can be created easily and reliably. A completely new printing / printed material bonding structure that does not require perforations has been developed (Japanese Utility Model Application No. 1-96604 (Japanese Utility Model Application Laid-Open No. 1-36887)),
No. 66333, Japanese Patent Application No. 2-30446, etc.).

It is an object of the present invention to provide a printed / printed matter bonding structure that can further enhance the commerciality of the printed / printed matter in such a situation.

(Means for Solving the Problems) As a result of intensive studies to solve the above-mentioned problems, the present inventor has found that in the above-mentioned printed / printed material bonding structure, heat sealing is required to ensure uniform and reliable adhesion. Although the agent is applied uniformly on the paper surface, if the paper surface is bonded in a zipper shape by giving a strong and weak change in adhesive strength, the heat sealing temperature can be lowered and the strong bonding area is small, The present invention was completed by paying attention to the fact that there is almost no inter-sheet peeling or tearing due to the thin peeling of the paper surface, and furthermore, a discontinuous sound of "burr" can be generated at the time of peeling to attract the interest of peeling.

Therefore, the bonding structure of the printed / printed material according to the present invention is a heat-sealable agent layer for low-temperature bonding having a predetermined repetitive pattern on at least one of the superposed paper surfaces of the print / print paper, and a predetermined repetitive pattern on the other. The gist is that a low-temperature bonding heat-sealing agent layer or a planar low-temperature bonding heat-sealing agent layer is formed, the printing / printing papers are overlapped and heat-sealed, and they are releasably attached to each other. I do.

Here, the present invention can be applied to any printing / printed material to be bonded, and can be used for direct mail, advertising leaflets, and the like.

The patterned heat sealant layer may be formed on at least one of the superposed paper surfaces, for example, a patterned heat sealant layer on one paper surface and a planar heat sealant layer or a patterned heat seal layer on the other paper surface. What is necessary is just to form a sealant layer. When the patterned heat-sealing agent layer is formed on both sides of the paper, a part of the patterned heat-sealing agent layer is strongly adhered releasably to each other, and the remaining portion is weakly adhered releasably to the facing paper, and is adhered. It is preferable in terms of adhesiveness and peelability.

In addition, as the heat sealant for low-temperature bonding, a commercially available product, for example, an EVA-based hot-melt type adhesive can be used. It is preferable to use the material while adjusting the peel strength. The adhesive strength is, for example, the adhesive strength between heat sealants is 100 to 200 g / 15 mm ^2.
It is desirable that the adhesive strength between the heat sealant and the paper surface be lower than that.

Further, the patterned heat sealant layer may be formed by applying the heat sealant in a predetermined pattern, or by applying the heat sealant uniformly and applying a varnish while leaving the predetermined pattern thereon. To expose the heat sealant. Further, the pattern of the heat sealant layer may be formed with a predetermined width around the entire outer edge of the overlapped surface, or may be formed on substantially the entire surface of the overlapped surface, and may be selected according to the type of print / printed matter. . The pattern may be any pattern as long as it is a predetermined repeating pattern,
For example, a pattern in which a V-shape, a W-shape or a ring shape is continuously repeated, a saw-tooth-shaped pattern, or a pattern in which these are appropriately combined can be used.

(Operation) In the present invention, since the paper surface is stuck in a pattern by the patterned heat sealing agent layer, the heat efficiently acts on the heat sealing agent and the paper surface during heat sealing, resulting in a very high temperature. The paper surface is stuck without heating, and the paper surface is securely stuck by the patterned heat sealant, so that the paper is not easily peeled off.

In addition, when the paper is peeled, the paper surface is stuck in a pattern by the patterned heat sealant layer, so when the paper is peeled, a discontinuous sound called “burr” is emitted, making the peeling operation very interesting. In addition, since the bonding area is small, a part of the paper is not peeled off or peeled at the time of peeling, and the paper surface is peeled off with good appearance.

(Example) Hereinafter, the present invention will be described in detail based on a specific example shown in the drawings.

FIGS. 1 to 3 show printing and printing according to an embodiment of the present invention.
2 shows a structure for bonding printed matter. In the drawing, reference numeral 1 denotes a postcard (printing / printing paper) having a size twice as large as a normal postcard, and the postcard paper 1 is folded in half with a folding line 2 extending in the center in the width direction and extending in the longitudinal direction. Thereby, the first and second front surfaces 10, 11 and the rear surfaces 12, 13 are formed,
The first surface 10 is a destination surface, and the second surface 11 and the first and second back surfaces 12 and 13 are printing / printing surfaces.

A low-temperature bonding heat sealant 3 that adheres at a predetermined peel strength to the entire outer periphery of the first and second back surfaces 12 and 13 is formed in a pattern in which a substantially V-shape is continuously repeated in a predetermined direction a plurality of times. And the first and second front surfaces 10, 11 and the back surface
Printing and / or printer printing is performed on 12 and 13, and the postcard paper 1 is heat-sealed in a folded state and bonded to the structure of this embodiment.

 Next, the operation and effect will be described.

When creating a postcard having this bonding structure, a substantially V-shaped pattern is repeatedly applied to the outer peripheral edges of the back surfaces 12 and 13 of the postcard paper 1 in a predetermined direction, and the second front surface 11 and the first and second surfaces 11 and 13 are applied.
After performing necessary printing and / or printer printing on the back surfaces 12 and 13, the postcard paper 1 is sent to a folding machine (not shown) or the like, and folded into two by a folding mold 2, and in that state, a heat sealing machine ( (Not shown) depending on relatively low temperature, for example 60-80 ° C
After applying heat, the first back surface 12 and the second back surface 13 are attached by heat sealing, and then an address is printed on the first surface 10 or a sticker on which the address is printed is attached to obtain a desired postcard. Can be

In this sticking process, since the heat sealant 3 is applied in a pattern, the heat efficiently acts on the paper surfaces 12 and 13 and the heat sealant 3, and even if the paper surface 12 and 13 are not heated to a very high temperature, 13 can be applied efficiently, the heating temperature can be reduced as compared with the case where the heat sealing agent 3 is applied to the entire surface of the paper 12, 13, and the influence of heat on printing ink, printer toner, and the like can be reduced.

In this state, as shown in FIG. 3, the V of the heat sealant 3 on the first back surface 12 and the second back surface 12 is increased.
The letter-shaped shapes are superposed in a state where they are arranged in the opposite directions to each other, and a part 30 of the pattern-shaped heat sealants 3 is strongly adhered to each other so as to be peelable from each other, and the remaining portion 31 faces the first or second back surface 1.
The heat sealants 3 are strongly adhered to each other in a chain form, and the paper 1 is firmly adhered to the heat sealants 3 and 13, and the heat sealant 3 and the paper 1 are weakly adhered to each other. As a result of the entire portion of the paper 1 to be adhered being adhered, the paper 1 is not easily peeled off, and the print / print items are kept secret.

On the other hand, when viewing the contents of the first and second back surfaces 12 and 13 that have been bonded together, slightly peel off one of the first or second back surfaces 12 and 13 with a nail or the like, and pinch the portion with a finger to completely remove the entire surface. What is necessary is just to peel off.

At that time, the adhesive strength between the heat sealants 30 is large,
The adhesive strength between the heat sealant 31 and the paper surfaces 12 and 13 is low, and the adhesive strength between the two is different. As a result, a discontinuous sound called “burr” is generated with the peeling of the paper surfaces 12 and 13, making the peeling operation very interesting. The postcard can be made more productive.

In addition, since a part of the pattern-shaped heat sealant 3 is strongly adhered and the strongly adhered area is small, a part of the postcard paper 1 is peeled off thinly at the time of peeling, so-called inter-sheet peeling does not occur.
Also, there is no tearing caused by paper separation
2, 13 can be peeled off with good appearance.

FIGS. 4 to 6 each show a modification of the above embodiment. In the modification shown in FIG. 4, the heat sealant 3 is formed into a pattern in which a plurality of ring-shaped portions are continuous, in the modification shown in FIG. 5, the heat sealant 3 is formed into a saw-tooth pattern, and in the modification shown in FIG. The W-shape is applied to a plurality of continuous patterns in a horizontal direction. Thus, even when a repetitive continuous pattern having a shape other than the V-shape is applied, the heat sealing agent 3
Can be bonded in a chain shape (see FIG. 4 (b), FIG. 5 (b) and FIG. 6 (b)).

FIG. 7 shows still another modification of the above embodiment. In this modified example, one of the paper surfaces 12 and 13 is formed into a strip shape in which the heat sealing agent 3 is continuous (see FIG. 1A), and the other paper surfaces 13 and 12 are spaced apart by a predetermined distance. Even if it is applied in this manner, when the paper surface is adhered, a part 32 of the heat sealant 3 is used as a sealant and the remaining part 33 is used as a sealant and the paper surface. Can be attached (see (c) of the same section). As shown in FIG. 2B, the heat sealing agent 3 may be applied in a band shape at a predetermined interval on both the paper surfaces 12 and 13, and a part of the heat sealing agent 3 at the time of application may be overlapped.

(Effects of the Invention) As described above, according to the printed / printed matter bonding structure according to the present invention, a heat-sealable agent layer for low-temperature bonding having a predetermined repetitive pattern is provided on at least one of the superposed paper surfaces of the printed / printed paper. Is formed, and the paper surface is heat-sealed so that it can be stuck in a pattern. By heating at a relatively low temperature, the printing / printing surface can be stuck securely. This has the effect of improving the merchantability of the printed / printed material and of being able to be peeled without causing inter-sheet peeling or tearing.
