Abstract

(57) [Abstract] [Problem] The recording surface does not become sticky even if the pseudo adhesive surface is peeled off.
A multi-layered postcard that can be produced in large amounts by a simple production method and can be produced inexpensively and has a large transmission amount. A multi-layered postcard including a postcard mount that is substantially the same as a normal postcard when folded from a folding line, and a resin layer that is adhered and formed on the surface of the postcard mount that is opposed by the folding. The postcard mount is folded and the opposing resin layers are pseudo-bonded. The pseudo-adhesion cannot be re-adhered after peeling.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a multi-layered postcard in which a recording surface of the postcard can be concealed and a recording area of the postcard can be made wider than ever before.

[0002]

[Prior art]

 In recent years, a distribution agency or the like often sends a printed matter for advertisement or advertisement to a customer, and the burden of the postage is great. The postage is cheaper for postcards than for envelopes.From this point, for example, advertising, advertising, or private information is printed on one side of a folded postcard, and the recording surfaces are pseudo-bonded to form a multilayer. A postcard has been proposed which is constructed so that the recording surface is hidden. By the way, as shown in FIG. 5, the currently proposed multi-layered postcards have a multi-layered structure in which a weak adhesive adhesive 53 is applied between the recording surfaces 52 and 53 of the two postcards 50 and 51. There is something to turn into.

Further, as shown in FIG. 6, a transparent polyethylene film 61 is laminated on a transparent polyester film base material 60 with a weak bonding force, and adhesive layers 62 and 63 are formed on both surfaces thereof, A label composed of release papers 64 and 65 attached to the adhesive layers 62 and 63 is prepared, the release paper is peeled off from the recording surface of the postcard, and the adhesive sheets are attached via the adhesive layers. When the recipient pulls both ends of the multi-layered postcard in opposite directions, it peels between the polyester film substrate 60 and the polyethylene film 61, and the folded postcard is opened.

[0004]

[Problems to be solved by the device]

 However, if a weakly sticky adhesive is used to make a postcard multi-layered, the recording surface becomes sticky when the pseudo-adhesive surface is peeled off, which makes the recipient uncomfortable. Moreover, re-adhesion is possible, which is not preferable in terms of private protection of the recording surface.

Further, when a label utilizing pseudo-adhesion between a polyethylene resin layer and a polyester resin layer is used, it is difficult to align the recording surface of the postcard and the label, and thus mechanical bonding is difficult. , It is not suitable for pasting a large number of copies.

Therefore, it is conceivable that a polyethylene resin layer is bonded to one of the recording surfaces of a postcard and a polyester resin layer is bonded to the other recording surface of the postcard directly with an adhesive to make pseudo-adhesion between different resins. Forming a different resin layer on the recording surface not only complicates the manufacturing process but also increases the manufacturing cost, so there is little merit in postcards having multiple layers and mailing advertisements and advertisements.

[0007]

[Action]

 In the multi-layered postcard of the present invention, since the one sheet of resin attached to the postcard mount faces the postcards in a folded manner, the pseudo-adhesion is made between the same type of resin.

[0008] Further, the pseudo-bonding is formed by heat fusion between the opposed resins, not through a tacky adhesive.

As a pseudo-bonding method that does not require a pressure-sensitive adhesive between the resins, there is, for example, point bonding due to unevenness on the surface of the resin layer. That is, the pseudo-adhesion is formed by point bonding due to the rough surface irregularities on the opposite surface side of the resin layer. As a means for making the surface of the resin layer rough, for example, there is a method of using a polyvinyl chloride resin as the resin layer and reflecting the unevenness of the paper surface of the postcard mount on the opposite side. In that case, the thickness of the resin layer affects the adhesive strength of the pseudo adhesive.

[0010]

[Embodiment of device]

 An embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of a multi-layered postcard of the present invention in which postcard mounts 10 and 11 are multi-layered with a pseudo adhesive surface 12. Although the example describes a two-fold postcard, a postcard having a recording area of three folds or more is also possible. FIG. 2 is a sectional view taken along the line I-I ′ in FIG. 1. Reference numerals 21 and 22 are recording surfaces of pictures and characters printed on a postcard mount, and information such as ordinary advertisements, advertisements, and finances are printed on them. Reference numerals 23 and 24 denote polyvinyl chloride resins formed on the recording surface, which are pseudo-bonded between the layers 23 and 24.

[0011]

【Example】

 Next, a method for manufacturing a multi-layered postcard according to the present invention will be described with reference to FIGS. 3 (A) to 3 (C). Reference numeral 30 in FIG. 3 (A) is a postcard base paper on which multiple postcard mounts are attached. In FIG. 3 (B), a postcard-sized design, characters, and the like are printed on the postcard base paper 30 in a multifaceted manner.

Next, a transparent polyvinyl chloride resin film having a thickness of 15 to 30 μm is laminated on the printing surface via an adhesive. The postcard mount formed on the postcard base paper in FIG. 3 (A) is a postcard that is folded in two, and is folded in a valley at the folding portions 33 and 34 of the postcard mount in FIG. I get a postcard base paper that is superposed like. Then, both sides of the superposed postcard base paper are heated and pressed by the heating and pressing roller device shown in FIG.

Reference numeral 40 denotes a silicon heater roll, which pushes out the postcard base paper 30 by upper and lower rollers. The extrusion speed is 1.5 to 2.0 m / min, the roller pressure is 8 Kg / cm ² , and the heating temperature is about 150 to 160 degrees. The postcard base paper thus obtained was cut into a postcard size to obtain a multi-layered postcard.

According to the present invention, a polyvinyl chloride resin is used for forming a multi-layered postcard, but normally the polyvinyl chloride resin layers are heat-sealed by heating and pressurization and it is difficult to remove them again. It is not suitable for the required multi-layered postcards.

Adhesion between polyvinyl chloride resin layers obtained under the conditions of resin thickness, roller pressure, roller speed, and heating temperature as described above is as shown in FIG. It is impossible to regenerate a pseudo-bonding which is a pseudo-bonding and has the same peeling property once peeled.

[0016] The postcard that is pseudo-adhesive and multi-layered has a bonding strength that does not peel off in normal handling, and when peeling off the postcard received by the recipient, the postcard is usually removed from the corner 13 of Fig. 1. Peel both sides of the postcard back in the opposite direction. For this reason, tensile stress partially concentrates and acts on the adhesive surface, so that the adhesive surface can be easily peeled off.

Further, a heat-sensitive adhesive is applied to the corners shown in FIG. 1 and adhered so as not to peel again, and when peeling off the adhesive surface, the broken line of the corner 13 is cut with scissors or the like, and the polyvinyl chloride resin interlayer is cut. If the device is devised so as to be peeled off, it is possible to further prevent accidental peeling during handling.

[0018]

[Effect of device]

 As described above, in the present invention, since the adhesive is not used for the pseudo adhesion, the recording surface is not sticky even if the pseudo adhesive surface of the recording surface is peeled off, and the re-adhesion is impossible. Further, since the pseudo-bonding of the present invention is formed between resin layers of the same type, the manufacturing process is simpler than that of pseudo-bonding between different resin layers, and the manufacturing cost can be kept low.
