Hereinafter, the present invention will be described in detail with reference to the drawings and the like. Figure 1-Figure 5 is a diagram showing an embodiment of a form according to the present invention, FIG. 1 is a perspective view, and FIG. 2 is a book view. 3 is a sectional view showing the adhesive sheet, and FIG. 4 is a sectional view showing the adhesive sheet. Figure 5 is a perspective view explaining the adhesion method, and Figure 6 is an enlarged view of part A in Figure 5. It is a diagram.

0012 Form 1 in this example was used for a mail form for postcards, and is shown in Figure 1. As shown in , it is a combination of a main body sheet 2 and an adhesive sheet 3.

[0013] As shown in FIG. This is a knowledge information printing surface 22. This main body sheet 2 can be folded in half approximately in the center. A vertical perforation p is formed, and a horizontal perforation q is formed at the top and bottom to separate the unit form. It is formed. Additionally, marginal portions r are provided on both sides of the main body sheet 2. The marginal punch hole s allows for continuous feeding during printing, and After printing, the marginal portion r can be separated by the vertical perforations t.

[0014] The main body sheet 2 may be any sheet-like material that has good printability, and is normally used for NIP paper is used depending on the printer used, but there are other materials as well. For example, PE, PP, PET, vinyl chloride, nonwoven fabric, etc. can be used. Main body The size, thickness, shape, etc. of the sheet 2 are not particularly limited, and can be selected as appropriate depending on the usage pattern. can. When used as an email form for postcards, as in this example, According to the current postal law, it is preferable to use a weight and shape that allows it to be treated as a postcard.

[0015] Unlike conventional mail forms, etc., the main body sheet 2 does not contain pressure-sensitive adhesive or pressure-sensitive adhesive. Since there is no adhesive applied, roll Piling, which generates adhesive residue due to rubbing with etc., and resistance when using a heat fixing roll. There are no problems such as heat resistance or blocking when stacking.

[0016] Adhesive sheet 3 is about half of the main sheet 2 separated into unit forms (Figure 1). As shown in FIG. It is formed. As the base material 31, substantially the same material as the main body sheet 21 can be used. sticky The adhesive layer 32 is coated with a pressure-sensitive adhesive that removably adheres to the main sheet 2. It is something that was given. This pressure-sensitive adhesive is made of natural rubber (NR), styrene, butane, etc. Polymethyl methacrylate with diene rubber (SBR) etc. as the main component for adhesion. rate (PMMA), vinyl acetate, micro silica, polymer resin, dispurge Emulsions containing ammonia, ammonia, wax, etc. can be used.

[0017] This adhesive sheet 3 has an adhesive layer 32 applied to almost the entire surface of a base material 31, and is currently used. It is necessary to apply it in a pattern like the tri-fold mail form for envelopes. Since there is no Coating methods such as the glue method can be used. This significantly increases manufacturing speed and costs In addition to reducing costs and shortening delivery times, documents that may otherwise be discarded due to printing errors, etc. There is no need to apply extra pressure-sensitive adhesive to the surface, making it extremely rational.

[0018] On the front and back surfaces of the right end of the adhesive sheet 3, as shown in FIGS. A release layer 33 is formed. The release layer 33 is the adhesive of the adhesive layer 32 of the adhesive sheet 3. This is a layer to weaken the force, and the part of the release layer 33 serves as a trigger for peeling. Becomes a department. The release layer 33 is coated with silicone, carnauba wax, etc., for example. It can be formed by This mold release layer 33 may be provided on the upper side or the lower side, or It may be provided only on one of the front and back surfaces.

[0019] It is preferable to store the adhesive sheet 3 in a rolled state. The reason for this is that the dryer Even if some trace remains, it can withstand use and can be easily rubbed with a roll, etc. This is because it can be used even if the piling is slightly weak because it will not be damaged.

[0020] Next, a specific manufacturing example of this form 1 will be given and explained in more detail. first, As the main body sheet 2, high-quality paper for NIP (FPLB-S, manufactured by Sanyo Kokusaku Pulp Co., Ltd., 70kg base), UV offset printing is applied to both the front and back sides, and the mirror is placed in the designated position. Thin holes p, q, and t and marginal punch holes s were formed. This main body sheet 2 , about 2000 sheets were folded in a zigzag pattern for each unit form.

[0021] In addition, as the adhesive sheet 3, a base material 31 of paper similar to the main body sheet 2 is coated with a UV After printing the necessary information using set printing, the horizontal perforation U is formed at the same time. Then, a pressure-sensitive adhesive is applied to the front and back surfaces of the base material 31 using a gravure method to form an adhesive layer 3. 2 and apply silicon to both sides of the right end to form a release layer 33. Then, a length of 300 m was prepared as a rolled-up state. The pressure sensitive adhesive has the following proportions: I used a mixture of. NR 15-20 copies SBR 10-15 copies Microsilica 5-10 parts Polymer resin 5-15 parts PMMA trace amount Vinyl acetate trace amount Ammonia trace amount Water 65-45 parts

[0022] Next, how to use the form 1 of this embodiment will be explained. First, address on body sheet 2 Use a printer such as NIP to write the necessary information on the printing surface 21 and the notification information printing surface 22. Print.

It may also be used as a holding portion that triggers separation.

[0028] The present invention is not limited to the embodiments described above, and various modifications and changes can be made. Within range. The explanation was given using the example of folding the main body sheet in two, but if you fold it in three and It is also possible to use a pressure-sensitive adhesive sheet for adhesion. Also, bi-fold, tri-fold However, the number of printed pages and the printed information are not particularly limited. difference Furthermore, even if the adhesive sheet and the main body sheet of the same size are overlapped alternately, good.

[0029] Also, the format for printing information may be continuous paper, cut paper, or printed paper. Printers are not limited to NIP, but also use thermal transfer methods, dot impact printers, etc. Good too.

[0030] Furthermore, instead of forming a pressure-sensitive adhesive layer on the main sheet, a strong adhesive layer is added to the adhesive sheet side. A pressure-sensitive adhesive (such as NR base) may be applied in a line to form a booklet. No way To prevent the package from being accidentally opened, mark all or part of the periphery so that it does not cover the area where the printing is planned. The strong pressure-sensitive adhesive layer may be provided in any manner.

[0031] Furthermore, if you print confidential information on the inside of the main body sheet or on the adhesive sheet, you can print confidential information on the inside of the main body sheet or on the adhesive sheet. It can also be used as a written email form. You can also print on adhesive sheets. If so, it may be printed over the adhesive layer.
