Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pseudo-adhesive sheet used for manufacturing an information communication body usable for post cards, reciprocating post cards, sealed letters, etc., including DM (direct mail), and information communication using the same. About the body. In detail, although the appearance is a normal DM, postcard, reciprocating postcard, or postcard, a multi-layered or folded sheet is releasably bonded between its opposing surfaces (hereinafter, pseudo adhesion). Therefore, the present invention relates to a pseudo-adhesive sheet used for manufacturing an information communication body capable of mailing while concealing a large amount of information, and an information communication body using the same.

[0002]

2. Description of the Related Art In recent years, an information communication body has been frequently used for postal items such as postcards, in which a plurality of leaf pieces on which information is described are pasted or folded to enable mailing while concealing a large amount of information. As such an information communication body, for example, as described in Japanese Utility Model Laid-Open No. 2-126877, there is a plastic film in which a polymerized surface is pseudo-adhered so as to be peelable. The information communication body of the related art utilizes a property of a heat-fusible transparent plastic film having a rough surface. However, if the heat-fusible plastic films are pressed against each other with heating,
It is well known that the opposing surfaces are completely fused and it is difficult to remove again, and the specification of the above-mentioned prior art also points out that fact. In order to solve the problem, in the above-mentioned conventional technology, a heat-fusible transparent plastic film having a thickness of about 15 to 30 μm is used as a processing condition for pseudo-adhering releasably, and the extrusion speed is set at 1.5.
~ 2.0m / min, pressing force by upper and lower roller is 8k
g / cm ² , and the heating temperature of the roller is set to an extremely narrow range of 150 to 160 ° C., so that the surface of the opposing plastic layer has a point joint due to its fine rough surface and a point other than the point joint. An unbonded portion is formed and the required pseudo-bonding is obtained. However, in the above-mentioned conventional technology, if even one of the processing conditions deviates from the set range, a defective bonding state or conversely, a complete bonding state in which re-peeling is impossible due to blocking due to thermal fusion occurs. A problem arises that the object cannot be achieved.

Therefore, as a means for producing a stable product without causing the above-mentioned problems such as adhesion failure and blocking, and expanding the range of processing conditions, a method of forming a resin layer on the surface of a transparent plastic film is considered. Can be That is, this is a method in which the transparent plastic films are pseudo-bonded to each other via another resin layer (hereinafter, referred to as a pseudo-adhesion resin layer). In this way, the transparent plastic film protects the information recording surface of the postcard paper even if the pseudo-adhesive resin layers are excessively heated and pressed so as to cause blocking between the pseudo-adhesive resin layers. What is necessary is just to break the interlayer and peel it off, and there is no trouble.

However, simply forming a pseudo-adhesive resin layer not only makes the peeling force not uniformly stable, but also causes patchy fogging on the peeling surface of the transparent plastic film when peeling and developing. The mottled cloudiness significantly impairs the aesthetics of art prints such as DMs, thereby resulting in inferior finishes of human models and product photographs, failing to bring out the value of the original product, and deterring user interest and purchase motivation. Significantly reduce. In the worst case, this leads to a decline in sales, resulting in claims for damages for the manufacturer of the information and telecommunications body, and a significant decrease in sales for the orderer.
A great deal of damage will occur on both sides. That is,
Such poor aesthetics can be the most fatal injury as a DM.

[0005]

Under heating and pressurization during the production of an information communication body, a required pseudo-adhesion can be obtained without causing poor adhesion or blocking even if processing conditions are not strictly set in a narrow range. Another object of the present invention is to provide a pseudo-adhesive sheet in which the peeling force of the pseudo-adhesion is uniformly stabilized and the occurrence of patchy fogging on the peeling surface after peeling and development is suppressed, and an information communication body using the same.

[0006]

Means for Solving the Problems In order to solve the above-mentioned problems, the present inventors have made intensive studies and, as a result, have found that a supporting resin layer having a thickness of 10 μm or more and a pseudo resin having a thickness of 4 μm or less are laminated and formed by a co-extrusion method. Use of a pseudo-adhesive sheet comprising a combination of at least two layers including an adhesive resin layer, wherein the pseudo-adhesive resin layers are opposed to each other and can be peelably pseudo-adhered by pressing under pressure or under heating. And found that it can be solved. The pseudo-adhesive sheet according to the present invention also includes the concept of a film.

The support resin layer used in the present invention has a relatively strong stiffness including, for example, at least one resin selected from the group consisting of polyethylene terephthalate, polypropylene, polyethylene, acetate, polycarbonate and polyamide resin. What consists of resin which does not stretch easily is used suitably. In addition, if necessary, known antiblocking agents, coupling agents, tackifiers, various waxes, plasticizers, fillers, release agents, lubricants, antioxidants, and the like are added to the resin. You may.

The pseudo-adhesive resin layer used in the present invention includes, for example, polyethylene, ethylene-vinyl acetate copolymer (EVA), ethylene-ethyl acrylate copolymer (EEA), and ethylene-acrylic acid copolymer. Polymer (EA
A) A resin composed of a resin having a relatively low softening temperature, including at least one resin selected from the group consisting of polyamide, ionomer, acryl, polyvinyl chloride and polyvinylidene chloride-based resin, is preferably used. The resin may contain a known antiblocking agent, coupling agent, tackifier, various waxes, plasticizer, filler, release agent, lubricant, antioxidant, and the like.

Each resin of the supporting resin layer and the pseudo-adhesive resin layer is formed as one (two-layer) sheet by co-extrusion. The co-extrusion of the present invention comprises a multilayer T-die method and a multilayer inflation method. And any of unstretched multilayers and stretched multilayers may be used.

[0010] As a method of laminating a pseudo-adhesive sheet on a leaf piece surface when manufacturing an information communication body,
A method according to the layer configuration of the pseudo-adhesive sheet can be appropriately adopted. That is, when the pseudo-adhesive sheet is composed of a supporting resin layer and a pseudo-adhesive resin layer, and the adhesive layer is not previously formed on the surface of the supporting resin layer opposite to the surface on which the pseudo-adhesive resin layer is formed, for example, Alternatively, a dry laminating method may be employed in which the supporting resin layer of the pseudo-adhesive sheet to be bonded to one another and one or both bonding surfaces of leaf pieces such as printing paper are laminated while applying an adhesive. Also,
By previously forming an adhesive layer made of a heat-sensitive adhesive or a pressure-sensitive adhesive on the surface of the supporting resin layer of the pseudo-adhesive sheet opposite to the surface on which the pseudo-adhesive resin layer is formed, the heat-sensitive adhesive layer In this case, a thermal laminating method can be employed, and in the case of a pressure-sensitive adhesive layer, a cold laminating method can be employed. The heat-sensitive adhesive layer includes, for example, polyethylene, ethylene-vinyl acetate copolymer (EVA), ethylene-ethyl acrylate copolymer (EEA),
A resin made of a resin containing at least one resin selected from the group consisting of an acrylic acid copolymer (EAA), a polyamide, an ionomer, and an acrylic resin is preferably used. The adhesive layer may be formed simultaneously with the support resin layer and the pseudo-adhesive resin layer by a co-extrusion method, together with those layers, if necessary, including other layers, or may be formed already. It is also possible to form on the pseudo-adhesive sheet by various coating methods and laminating methods.

In the present invention, information is obtained by using a pseudo-adhesive sheet manufactured by the above-described method, and by pseudo-adhering any of opposing surfaces of a plurality of superposed leaf pieces in a releasable manner via the pseudo-adhesive sheet. A communication body can be manufactured, in which case, the pseudo-adhesive sheet is coated on each of the pseudo-adhesion surfaces of the facing surface by the laminating method, and the exposed pseudo-adhesive resin layers are opposed to each other and pressed or pressed. What is necessary is just to pseudo-adhesively detachably by pressing under heating and to integrate. At the time of manufacture, if the information communication body is finished so as to conform to the standards set forth in the Postal Law, it is possible to mail more information at a normal postcard fee or envelope letter fee.

Various types of paper, including known printing paper, can be used for the information communication body according to the present invention. In addition to the printing paper, the paper may be, for example, synthetic paper or a plastic sheet or cloth obtained by mixing paper and resin, and a continuous long sheet used for business form printing or rotary printing. It may be a plain-sheet-like one used for offset printing, gravure printing, or the like.

[0013] The information communication body according to the present invention is such that an arbitrary opposing surface formed by cutting or folding or folding a plurality of leaf pieces is quasi-adhered with the quasi-adhesive sheet. Therefore, it is not necessary to pseudo-adhere all the opposing surfaces, and there may be an opposing surface that is not completely opened after being completely bonded, or an opposing surface that remains free and does not undergo pseudo adhesion or complete adhesion. Further, the plurality of leaf pieces may be folded in a bellows-like shape, a roll-like shape, a double-folded shape, or a state in which the plurality of folds are mixed, in addition to the two-fold or Z-fold. May be mixed. The state of adhesion and the state of superposition of these opposing surfaces may be designed at any time so as to maximize the effect according to the purpose and use of the information communication body to be manufactured.

When the information communication body according to the present invention is used as a postcard, for example, in the case of a two-leaf piece, there are a form in which a postcard double-size sheet is folded in two, and a form in which two postcard-size sheets are stacked. In the case of a three-leaf piece, the two opposing surfaces generated by Z-folding or C-shaped winding are all quasi-adhered, and the three-leaf piece can be developed in a plane, or one opposing surface can be peeled off. And the remaining one facing surface may be completely bonded so that it cannot be peeled off. Further, the one facing surface may be pseudo-bonded so as to be peelable and the remaining one facing surface remains free. It is also possible to make a two-way spread postcard without doing anything. Of course, after peeling and developing, all the leaf pieces may be separated separately, and a form in which a separate leaf piece is attached to the two-folded two leaf pieces may be used.

[0015]

In the quasi-adhesive sheet according to the present invention, the supporting resin layer and the quasi-adhesive resin layer are each formed to have a constant thickness by a co-extrusion method. When simulated bonding is performed by applying a lower pressure, the peeling force is uniform and stable. Further, the pseudo-adhesive sheet according to the present invention employs a configuration in which the thickness of the pseudo-adhesive resin layer is 4 μm or less, preferably 2 μm or less, as an important factor for eliminating patchy fogging on the release surface. . According to a plurality of experimental results, when the thickness of the pseudo-adhesive resin layer exceeds 4 μm, mottled fogging is remarkably exhibited and the aesthetic appearance is remarkably impaired, and the peeling force is also increased, which causes curling during peeling. . On the other hand, in the present invention, an important condition is that the thickness of the supporting resin layer is 10 μm or more. According to a plurality of experimental results, when the thickness of the supporting resin layer is less than 10 μm, the transparency of the pseudo-adhesive sheet has no depth and the degree of gloss decreases, and consequently the spotty clouding on the peeling surface is emphasized. It will be.

According to experiments by the present inventors, biaxially oriented polypropylene (OPP) -based resin was used as the resin of the support resin layer.
Ethylene-vinyl acetate copolymer (EVA) resin is selected as the resin for the pseudo-adhesive resin layer, and the coextrusion method is used so that the thickness of the support resin layer is about 19 μm and the thickness of the pseudo-adhesive resin layer is about 2 μm. A pseudo-adhesive sheet was produced. The quasi-adhesive sheet is placed on a high-quality paper (12
8 g / m ² ) Laminated on the surface by a dry lamination method, and the obtained laminated paper stock was cut into a postcard double size to obtain a two-fold postcard paper. The two-fold postcard paper is folded in two such that the pseudo-adhesive resin layer faces each other,
It was passed through a heat roller (pressing pressure 10 kg / m ² , heating temperature 90 ° C.) to apply pressure under heating to pseudo-bond the opposing pseudo-adhesive resin layers to each other. The mold peel strength was about 30 g / 50 mm, uniform and good pseudo-adhesion without curl at peeling was obtained, and no mottled clouding occurred on the peeled surface after peeling and development.

On the other hand, 9 μm under the same conditions as in the above test.
When a supporting resin layer made of an OPP-based resin having a thickness of m or 7 μm was used, in each case, mottled cloudiness was noticeable in a solid printing portion of a dark color system. In addition, under the same conditions as in the above test, 5
When the pseudo adhesive layers made of EVA resin having a thickness of 7 μm and 7 μm were used, the peeling force was too strong, the curl at the time of peeling was tight, and the entire peeling surface was mottled.

The pseudo adhesive sheet G shown in FIG.
A support resin layer 2 having a thickness of 0 μm or more and a pseudo-adhesive resin layer 1 having a thickness of 4 μm or less are laminated and formed as one sheet by a co-extrusion method. This configuration is compatible with a dry lamination method in which an adhesive is applied to one or both adhesive surfaces of leaf pieces of printing paper 2 described later and printing paper. The pseudo-adhesive sheet G shown in FIG. 2 is the same as the pseudo-adhesive resin layer 1 in the support resin layer 2 of the pseudo-adhesive sheet shown in FIG.
An adhesive layer 3 made of a heat-sensitive adhesive or a pressure-sensitive adhesive is provided in advance on the surface on the opposite side, and has a configuration corresponding to a thermal lamination method or a cold lamination method.
Any pseudo-adhesive sheet requires an adhesive to be laminated on printing paper or the like, and both can be used properly in accordance with the laminating method.

As shown in FIG. 3A, printing paper S has
Four bi-fold postcard sheets t in which the first leaf piece 11 and the second leaf piece 12 are connected in the horizontal direction via the folding line 13 are printed. On the surface of the first leaf 11, general information 15 such as the advertisement of the sender is printed and printed, and on the surface of the second leaf 12, the address and name 14 of the recipient are printed and printed in addition to the postage stamp column and the postal code column. ing. Note that the address name 14 may be printed by a printer connected to the computer during the process of manufacturing a two-fold postcard or after completion of all operations.
Then, as shown in FIG. 3B, on the back surface of the printing paper S,
When the two-fold postcard is completed, personal information, general information, and the like of the recipient are printed as so-called concealed information 16 that cannot be visually recognized from the outside.

In this state, the pseudo-adhesive sheet G is laminated on the back surface of the printing paper S on the support resin layer 2 side (the display side of the concealment information 16 shown in FIG. 3) by a dry lamination method, and then dried. And is individually cut into the state of a single folded two-fold postcard sheet t. The two-fold postcard sheet t obtained in this manner is in a state where the entire back surface is laminated with the pseudo adhesive sheet G as shown in FIG. When folded, the pseudo-adhesive resin layer 1 is in a state of facing as shown in FIG.

If the folding line 13 is slightly displaced from the center, the unsealing edge is displaced when folded, and a step is formed along the unsealing edge. Such a step is a starting point of opening, and it is convenient because the two-fold postcard can be easily peeled and developed. In addition to the above, a step may be formed by providing a notch in a corner portion, or a slit or a perforation may be formed on the opening edge side, and then broken and opened. You may do so. Alternatively, the pseudo-adhesive sheet G may be slightly stuck to the inside along the opening edge, and the non-adhesive portion generated at the edge may be used as a clue for opening.

The two-fold postcard with the pseudo-adhesive resin layer 1 facing as described above is pressed under heat by a known method using a heat roller, a heater panel, and a press roller (not shown). Similarly, the pseudo bonding is completed by applying pressure by a known method such as a press stacker (not shown), thereby being integrated in a releasable manner and with a two-fold postcard as an information communication body as shown in FIG. Become.

The recipient of the two-fold postcard starts with a step D formed along the opening edge as shown in FIG.
The first leaf piece 11 and the second leaf piece 12 can be peeled and developed with a finger. Then, the two-fold postcard is peeled and developed in a state as shown in FIG. 4B before folding, whereby the exposed concealment information 16 is visually recognized through a transparent pseudo-adhesive sheet G without mottled cloudiness. It becomes possible.

Next, a case where a three-leaf postcard is manufactured by folding three-leaf pieces in a Z-fold (Z-shaped cross section) will be described. As in the case of the above-described two-leaf piece, the pseudo-adhesive sheet G is laminated in a spot manner on each pseudo-adhesive surface of printing paper (not shown) on which a plurality of tri-fold postcard papers u made of three-leaf pieces are printed. 6 (A) to 6 (C) are individually cut into the state of single tri-fold postcard paper u.

6 (A) to 6 (C), the tri-fold postcard u has a first leaf piece 21, a second leaf piece 22 and a third leaf piece 23 connected in a horizontal direction via folding lines 24 and 25. In other words, the concealment information 27 is described on each surface of the first leaf piece 21 and the second leaf piece 22, and the address and name 26 of the recipient are described on the surface of the third leaf piece 23 together with the postage stamp column and the postal code column. . In addition, concealment information 28 is described on the back surface of each of the third leaf piece 23 and the second leaf piece 22, and general information 29 such as an advertisement is described on the back face of the first leaf piece 21.

As shown in FIG. 3C, the pseudo-adhesive sheet G is composed of the first leaf piece 21 on which the concealment information 27 is described and the second leaf piece 21.
It is laminated on each surface of the leaf piece 22 and on each back surface of the third leaf piece 23 and the second leaf piece 22 on which the concealment information 28 is described. Note that the back surface of the first leaf piece 21 is not a pseudo-adhesive surface and therefore does not need to be laminated.
If the back surface of 1 is laminated together with the back surfaces of the third leaf piece 23 and the second leaf piece 22 at once, the work efficiency is good, and in that respect, the back face may be laminated.

The laminated tri-fold postcard paper u obtained as described above is folded in a Z-shaped cross section by a folding machine (not shown), and the two-folded As in the case of the postcard, the pseudo-adhesion is completed at the same time as the postcard is pressed or heated, whereby the postcard is integrated in a releasable manner and becomes a tri-fold postcard as an information communication body as shown in FIG.

As shown in FIG. 7, the recipient of the tri-fold postcard begins with steps E and F formed on the left and right along the opening edge, and the first leaf piece 21, the second leaf piece 22, and the second leaf piece 2
The second and third leaf pieces 23 can be peeled off. Then, the tri-fold postcard is developed in a plane while all the three-leaf pieces are peeled off, so that a large amount of concealment information 27, 28 described inside can be converted into a mottled transparent pseudo-adhesive sheet G. You can see it through.

The present invention is not limited to the above embodiment. For example, as shown in FIG.
