Description

  The present invention relates to RFID tag manufacturing paper. The present invention also relates to an RFID tag manufacturing method using the RFID tag manufacturing paper.

  Applications of RFID (Radio Frequency IDentification) tags have expanded, such as cards (for example, see Patent Document 1), business cards (for example, Patent Document 2, see), and tags in a narrow sense (see, for example, Patent Document 3). It is widely used in the form of postcards. Hereinafter, in this specification, the term RFID tag is used in a broad concept including those having forms such as cards, business cards, narrow tags, and postcards. The tag shape includes the shape of a card, a business card, a narrow tag, and a postcard. On the other hand, an RFID label and an RFID sticker which are provided with an attachment surface for attachment and are attached to an object to be attached are not included in the RFID tag.

  In general, in order to manufacture an RFID tag, a dedicated manufacturing apparatus is required, so that it is difficult for an individual or a small business to manufacture the RFID tag on a small scale. Specifically, for example, in order to manufacture a card-type RFID tag, a forming process for forming a member into a card shape, an input process for inputting information into the RFID, and a printing process for performing necessary printing on the card surface are required. It becomes. Here, the input process can be performed on a small scale using a low-cost RFID writer. On the other hand, it is difficult to perform the formation process on a small scale. The printing process can be performed by using a dedicated printer corresponding to the card, but such a printer is generally expensive. There are also card writers with a printing function that simultaneously perform input and printing on a card, but they are generally expensive and the size of cards that can be handled is limited.

Can be printed on. Note that the standardized sheet shape is not only JIS standards such as A row such as A0, A1, B row such as B0, B1, etc., Hatron size, 46 format, and chrysanthemum format, but also international format (letter size) This is a concept that includes shapes that are essentially standard, such as postcards and cabinets. This is because general-purpose printers also support these shapes.

  Further, the RFID tag manufacturing paper is formed in such a manner that a cut in the shape of a card in plan view penetrates the peeling layer from the uppermost layer. In addition, the release layer is temporarily attached to the peelable layer and can be easily peeled off. Therefore, the peelable layer can be easily peeled by the user from the planar tag-shaped member formed by the peeling layer from the surface layer. Only by this peeling, the user can easily form the RFID tag.

  In the RFID tag manufacturing paper of the present invention, it is preferable that the release layer includes glassine paper, and a surface of the release layer that contacts the release layer is formed of low-density polyethylene.

  According to the above configuration, since the release layer includes glassine paper, and the surface of the peelable layer that is in contact with the peelable layer is formed of low-density polyethylene, the peelable layer is temporarily attached to the peelable layer and the peelable layer is peeled off.

  According to the above configuration, the surface of the glassine paper that contacts the layer to be peeled is sealed with polyvinyl alcohol, so that the layer to be peeled is temporarily attached to the peeling layer and the layer to be peeled is more easily peeled from the peeling layer. It becomes the structure which can be done. Moreover, since polyvinyl alcohol is also a general-purpose member, it can be easily taken.

  In the RFID tag manufacturing paper of the present invention, it is preferable that the printing layer is formed of a member capable of surface printing.

  According to the above configuration, since the printing layer is formed of a member capable of surface printing, it is easy to print on RFID tag manufacturing paper by surface printing with a page printer, ink jet printer, dot impact printer or the like. it can. Here, the surface printing is printing performed by coloring a member surface from the outside using a colorant such as ink. When the colorant stays on the surface of the member as in the case of using a pigment-based colorant, or when the colorant soaks into the member as in the case of the use of a dye-based colorant. Is also included.

  The RFID tag manufacturing paper of the present invention preferably includes a thermal color former that develops color when the printing layer is heated.

  According to the above configuration, since the thermal color former that develops color when heated is contained in the print layer, the thermal color former is colored by using a thermal printer that prints by heating the printed material. It can be easily printed on tag production paper.

[First Embodiment]
Hereinafter, an embodiment of an RFID tag manufacturing paper and an RFID tag manufacturing method to which the present invention is applied will be described with reference to FIGS. In the following description, the directions and directions described in FIGS. 1 and 2 are used.

[Embodiment of RFID tag manufacturing paper]
As shown in FIG. 1, the RFID tag manufacturing paper has an A4 size sheet shape as a whole. A coated paper layer 20 made of a normal paper material is formed on the uppermost layer side in the thickness direction. Therefore, printing can be easily performed with a normal printing machine, a home inkjet printer, an office page printer, or the like.

  Further, a cut C is formed in this sheet shape, and a plurality of card-type tag shapes in plan view are formed by the cut C.

  As shown in FIG. 2, which is a cross-sectional view taken along line AA of FIG. 1, the RFID tag manufacturing paper has a multilayer structure. A fine paper layer 73 is laminated on the lowermost layer side in the thickness direction. Therefore, the surface roughness on the lower layer side is equivalent to that of normal paper.

  In general, in a home printer or office printer, a printed material is conveyed using a frictional force generated between a roller and the conveyed material. Therefore, if this frictional force is different from the designed value, there is a possibility that the substrate to be printed is not conveyed well. Since the high quality paper layer 73 is laminated on the lowermost layer side of the RFID tag manufacturing paper, it is possible to suppress the occurrence of conveyance failure in a home printer or office printer designed on the assumption of paper.

  On the upper layer side of the fine paper layer 73, a low density polyethylene layer 71 is laminated via an acrylic pressure-sensitive adhesive layer 72. A layer to be peeled 70 is formed by the low density polyethylene layer 71, the acrylic pressure-sensitive adhesive layer 72, and the fine paper layer 73.

  On the upper layer side of the low density polyethylene layer 71, a glassine paper layer 61 whose lower layer side is sealed by a polyvinyl alcohol layer 62 is laminated. That is, the release layer 60 is formed by the glassine paper layer 61 and the polyvinyl alcohol layer 62. The peelable layer 70 is temporarily attached to the peelable layer 60 by applying pressure. Therefore, the peelable layer 70 can be easily peeled from the release layer 60.

  On the upper layer side of the release layer 60, a communication layer 40 having an RFID function is formed via an acrylic pressure-sensitive adhesive layer 50. More specifically, the communication layer 40 has a structure in which a polyethylene terephthalate film layer 43 is laminated with an acrylic pressure-sensitive adhesive layer 42 on an inlay 41 that records and transmits information. Note that the communication layer 40 is not laminated so as to cover the entire upper layer side of the acrylic pressure-sensitive adhesive layer 50, but is laminated only partially as shown in FIG.

  On the upper layer side of the communication layer 40, a coated paper layer 20 that functions as a printing layer is formed via an acrylic pressure-sensitive adhesive layer 30. In this embodiment, the coated paper layer 20 also ensures the strength of the RFID tag manufactured using the RFID tag manufacturing paper.

  The cuts C described above are formed in such a manner as to penetrate the release layer 60 from the coated paper layer 20. Therefore, the user can easily form the RFID tag by peeling the layer to be peeled 70 from the tag forming portion 10 in the upper layer from the peeling layer 60 formed in the tag shape by the notch C.

  2 is a schematic cross-sectional view for explaining the configuration of the RFID tag manufacturing paper, the thickness of each layer and the ratio between the horizontal direction and the thickness direction are not realistic. Moreover, since each layer has flexibility, the interface of each layer is not necessarily linear. For example, the portion where the communication layer 40 is not laminated on the upper layer side of the acrylic pressure-sensitive adhesive layer 50 does not have a gap as shown in FIG. 2, but the coated paper layer 20 is laminated.

  More specifically, the peeled layer 70 has a thickness of 95 μm. The thickness of the RFID tag manufacturing paper as a whole is 645 μm at the thickest part and 285 μm at the thinnest part. As described above, since the RFID tag manufacturing paper has the communication layer 40 laminated on a part thereof, there is a thicker part than other parts. This portion corresponds to the thickest portion. Conversely, the thickness of the portion where the communication layer 40 is not laminated is smaller than that of the portion where the communication layer 40 is laminated. Since the portion where the communication layer 40 is laminated is a small part of the RFID tag manufacturing paper, the average thickness for manufacturing the RFID tag is substantially equal to the thickness of the thinnest portion.

  It should be noted that even if the thickness of the thickest part exceeds the paper thickness allowed by a general printing machine, there is no actual problem. As described above, the thickest portion, that is, the portion where the communication layer 40 is laminated is a part that is extremely limited when viewed from the whole RFID tag manufacturing paper, and therefore, a paper that is particularly problematic when printing by a printing press. This is because there is almost no influence on the stiffness and followability of the roller.

[RFID tag manufacturing method]
Next, an RFID tag manufacturing method using the RFID tag manufacturing paper will be described.

(Input process)
There is no particular limitation on the input process for inputting desired information to the RFID. For example, in order to carry out small-scale production, individual input may be performed using a low-cost RFID writer. In this case, the same information may be input to the entire RFID card manufactured using the RFID tag manufacturing paper, or different information may be input for each RFID card. Further, when manufacturing a large number of RFID cards to which the same information is input, an RFID tag manufacturing sheet including the communication layer 40 in which necessary information is input in advance may be used.

(Printing process)
The printing process for performing necessary printing on the card surface can be easily performed by a printer that is widely used for home use or office use. As described above, since the RFID tag manufacturing paper is an A4 size sheet as a whole, it is not necessary to use a special printer. Also, the printing format is not particularly limited as long as it is a printer format that prints on ordinary paper, such as a page printer, an inkjet printer, a dot impact printer, a thermal transfer printer, or the like. There is no problem whether the ink stays on the surface of the member or the ink soaks into the member. In addition, since the uppermost layer and the lowermost layer of the RFID tag manufacturing paper are both paper materials, there is a possibility that problems such as paper jams will occur due to the fact that normal paper printers cannot be transported by the transport roller. Is small.

(Formation process)
As described above, the forming process for forming the member into the card shape is completed only by peeling the peelable layer 70 from the card-shaped tag forming portion 10 of the RFID tag manufacturing paper. Since a plurality of card-type tag shapes in plan view are formed by the cuts C, each of the plurality of members surrounded by the cuts C becomes an RFID card by peeling the layer 70 to be peeled off.

According to the present embodiment described above, the following effects can be obtained.
(1) In the present embodiment, the RFID tag manufacturing paper has a coated paper layer 20 that can be printed and has an A4 size sheet shape, so that it can be used for home inkjet printers and office page printers. Etc. can be printed easily.

  (2) The RFID tag manufacturing paper is formed in such a manner that the cut C having a card shape in plan view penetrates the release layer 60 from the coated paper layer 20 which is the uppermost layer. The release layer 60 is temporarily attached to the peelable layer 70 and can be easily peeled off. Therefore, the peelable layer 70 can be easily peeled from the planar card-shaped member formed from the coated paper layer 20 by the peeling layer 60. Only by such peeling, the user can easily form a card-shaped RFID tag.

  (3) In the present embodiment, the release layer 60 includes glassine paper as a constituent element, and the surface of the peelable layer 70 that is in contact with the release layer 60 is a low density polyethylene layer 71 formed of low density polyethylene. Accordingly, the general-purpose member has a configuration in which the peelable layer 70 is temporarily attached to the peelable layer 60 and the peelable layer 70 can be easily peeled from the peelable layer 60.

  (4) In this embodiment, the surface of the glassine paper layer 61 that contacts the layer to be peeled 70 is sealed with the polyvinyl alcohol layer 62, so that the layer to be peeled 70 is temporarily attached to the peeling layer 60 and The release layer 70 can be easily peeled from the release layer 60. Moreover, since glassine paper and polyvinyl alcohol are also general-purpose members, such a configuration is easily possible.

  (5) In this embodiment, since the coated paper layer 20 that is a printing layer is formed of art paper that is a member capable of surface printing, surface printing is performed by a page printer, an ink jet printer, a dot impact printer, or the like. By doing so, it is possible to easily print on the RFID tag manufacturing paper.

  (6) In this embodiment, since the lowermost layer is formed of the high-quality paper layer 73 that is a paper member, it is easy to print using a printer designed on the assumption that printing is performed on paper. .

[Second Embodiment]
Hereinafter, an RFID tag manufacturing sheet according to a second embodiment of the present invention will be described with reference to FIGS. In the second embodiment, the print layer and the size in the first embodiment are changed. Therefore, parts having similar functions are denoted by the same reference numerals, and description thereof is omitted.

[Embodiment of RFID tag manufacturing paper]
As shown in FIG. 3, the RFID tag manufacturing sheet has a B4 size sheet shape as a whole. The uppermost layer in the thickness direction is formed by a protective layer 21 formed of a known member that can be easily printed by a normal printing machine, a home inkjet printer, an office page printer, or the like. Yes.

  Further, a cut C is formed in the sheet shape, and a plurality of postcard-like tag shapes in plan view are formed by the cut C.

  As shown in FIG. 4 which is a BB sectional view of FIG. 3, the RFID tag manufacturing paper has a multilayer structure. The layers from the fine paper layer 73 at the lowest layer in the thickness direction to the communication layer 40 toward the upper layer side are laminated in the same manner as in the first embodiment. On the upper layer side of the communication layer 40, a heat sensitive layer 22 formed of a heat sensitive paper containing a heat sensitive colorant that develops color when heated through the acrylic pressure-sensitive adhesive layer 30 is laminated. The thermosensitive color former is not particularly limited, and a general-purpose product may be used. For example, a heat-sensitive color former containing a leuco dye, a developer, a dispersant and a binder can be exemplified.

  A protective layer 21 that protects the heat-sensitive layer 22 from a heating head (not shown) for heating the heat-sensitive layer 22 is laminated on a further upper layer of the heat-sensitive layer. Further, the protective layer 21 is formed of a known member capable of normal surface printing. Therefore, in the second embodiment, the print layer is formed of the heat-sensitive layer 22 and the protective layer 21.

  The above-described cuts C penetrating the release layer 60 from the protective layer 21 are formed. Therefore, the user can easily form the RFID tag by peeling the layer to be peeled 70 from the tag forming portion 10 in the upper layer from the peeling layer 60 formed in the tag shape by the notch C.

[RFID tag manufacturing method]
Next, an RFID tag manufacturing method using the RFID tag manufacturing paper will be described. The “input process” is not particularly different from that of the first embodiment, and thus the description thereof is omitted.

(Printing process)
A printing process for performing necessary printing on the card surface can be easily performed by a general-purpose thermal printer. As described above, since the RFID tag manufacturing paper is a B4 size sheet as a whole, it is not necessary to use a special printer. In addition, since the uppermost layer and the lowermost layer of the RFID tag manufacturing paper are both paper materials, there is a possibility that problems such as paper jams will occur if the thermal printer for normal paper cannot be transported by the transport roller. Is small.

  If necessary, it is possible to perform overprinting with a printer widely used for home use or office use in combination with printing by a thermal printer. Also in this case, since the RFID tag manufacturing paper is a B4 size sheet as a whole, it is not necessary to use a special printer. Further, as described above, since the protective layer 21 is formed of a known member capable of normal surface printing, the printing format is not particularly limited. A printer type that prints on ordinary paper, such as a page printer, an inkjet printer, or a dot impact printer, can be used. There is no problem whether the ink stays on the surface of the member or the ink soaks into the member. In addition, since the uppermost layer and the lowermost layer of RFID tag manufacturing paper are both paper materials, there is a possibility that problems such as paper jams will occur if the printer for normal paper cannot be transported by the transport roller. Is small.

(Formation process)
As described above, the forming process for forming the member into the card shape is completed only by peeling the peelable layer 70 from the card-shaped tag forming portion 10 of the RFID tag manufacturing paper. Since a plurality of postcard-shaped tag shapes in plan view are formed by the cuts C, each of a plurality of members surrounded by the cuts C becomes an RFID postcard by peeling the layer 70 to be peeled off.

  According to the second embodiment described above, in addition to the effects (1) to (6) in the first embodiment, the following effects can be obtained.

  (7) According to the second embodiment, since the heat-sensitive color forming agent that develops color when heated is included in the heat-sensitive layer 22 as the printing layer, printing is performed by causing the printed material to be colored by heating. It is possible to easily print on the RFID tag manufacturing paper by coloring the thermal color former with a printer such as a thermal printer.

[Third Embodiment]
Hereinafter, an RFID tag manufacturing sheet according to a third embodiment of the present invention will be described with reference to FIG. In the third embodiment, since the RFID tag manufacturing paper size and the cut C in the first embodiment are changed, the same reference numerals are given to parts having similar functions, and the description thereof is omitted. Is omitted.

[Embodiment of RFID tag manufacturing paper]
As shown in FIG. 5, the RFID tag manufacturing paper has a postcard-like sheet shape as a whole. A coated paper layer 20 made of a normal paper material is formed on the uppermost layer side in the thickness direction. Therefore, printing can be easily performed with a normal printing machine, a home inkjet printer, an office page printer, or the like.

  Further, a cut C is formed in the sheet shape, and only one card-type tag shape in plan view is formed by the cut C. Although not shown in the figure because it is the same as in the first embodiment, this cut C is formed in a manner that penetrates the release layer from the coated paper layer 20. Therefore, the user can easily form the RFID tag by peeling the layer to be peeled from the tag forming portion in the upper layer from the peeling layer formed in the tag shape by the cut C.

[RFID tag manufacturing method]
Next, an RFID tag manufacturing method using the RFID tag manufacturing paper will be described. Here, since the “input process” and the “printing process” are the same as those in the first embodiment, description thereof is omitted.

(Formation process)
The forming process for forming the member into a card shape is completed only by peeling off the layer to be peeled from the card-shaped tag forming portion of the RFID tag manufacturing paper. Since the card shape tag shape in plan view is formed by the cut C, the member surrounded by the cut C becomes an RFID card by peeling the layer to be peeled.

  By the way, in this embodiment, since the RFID tag manufacturing paper has a postcard shape, it can be mailed as it is after the “input process” and the “printing process”. In this case, the recipient takes charge of the formation process of forming the RFID card by peeling off the layer to be peeled off.

  For example, the RFID tag manufacturing paper can be used as a guide for an exhibition. In the printing process, customer-specific information as a recipient is printed on the part to be the RFID tag, and exhibition guide information and information necessary for mailing are printed on the other part. Moreover, customer specific information etc. are input as an input process. Thereafter, the RFID tag manufacturing paper is mailed directly to the customer. The received customer peels off the peelable paper layer from the RFID tag manufacturing paper as a guide and forms an RFID tag. Since the customer identification information and the like are printed and input on the RFID tag, it can be used as it is as a visitor chapter. As a result, the customer can enter the exhibition only by bringing the chapter of the visitors removed from the guide when entering the venue, thereby simplifying the entrance procedure. In addition, since the organizer of the exhibition can obtain information on the visitors simply by installing an RFID tag reader at the entrance of the exhibition, it is possible to easily grasp the visitors.

  According to the third embodiment described above, in addition to the effects (1) to (6) in the first embodiment and the effect (7) in the second embodiment, the following effects are obtained. Can do.

  (8) According to the third embodiment, since the sheet shape is a postcard shape, it can be mailed as it is after the printing step and the input step. Further, since the shape of the tag in plan view has the form of a card, an RFID tag in the form of a card can be easily formed by peeling off the peelable layer. In other words, the RFID tag manufacturing form that has been printed and entered can be mailed to customers as a guide for exhibitions and used to form RFID tags in the form of cards that serve as visitors' chapters of exhibitions. It is.

  In addition, you may change the said embodiment as follows.

  In the third embodiment, the RFID tag manufacturing paper is used as a guide for an exhibition, but may be used for other purposes. For example, it can be used for any arts or lectures that require admission management. Further, the input information is not limited to the customer specifying information. For example, if it is necessary to pay money for admission, it may be information indicating whether or not the customer has paid in advance, or information for debiting money from a pre-registered account. Also good.

  In the third embodiment, the coated paper layer 20 is laminated as the printing layer in the same manner as in each of the first embodiments. However, as in the second embodiment, from the heat-sensitive layer 22 and the protective layer 21. A printed layer may be formed. In this case, similarly to the second embodiment, it is possible to print on the RFID tag manufacturing paper by coloring the thermal coloring agent with a printer that prints by coloring the printed material by heating.

  In the first embodiment, the coated paper layer 20 is laminated as the print layer, but other configurations may be used. The point is that printing can be performed by a general-purpose printer. Therefore, a layer formed of resin or the like may be used as long as the printer supports normal paper materials.

  In each of the above embodiments, the RFID tag manufacturing method includes an input process, a printing process, and a forming process, but may not include all of them. For example, you may perform an input process and a printing process simultaneously using the card writer with a printing function. If an inlay of a type in which necessary information is input in advance is used as the inlay 41, the input process can be omitted. The same applies to the printing process. In short, the presence or absence of other processes is not particularly limited as long as it is a manufacturing method using RFID tag manufacturing paper.

  In each of the above embodiments, the lowermost layer is the fine paper layer 73, but other configurations may be used. In short, since it is sufficient that printing is performed without any problem by a printer designed on the assumption that printing is performed on paper, other general-purpose paper may be used. Further, if the printer to be used is compatible, a member other than paper, such as a resin film, may be used.

  In each of the above embodiments, the thickness of the RFID tag manufacturing paper as a whole is 645 μm at the thickest part and 285 μm at the thinnest part. In short, since there is no problem in printing with a general printing press, for example, the thickness of the RFID tag manufacturing paper as a whole may be 670 μm or less at the thickest portion and 310 μm or less at the thinnest portion.

  Further, the RFID tag manufacturing paper may be made thinner. However, as an application used as a card, it is preferable to maintain the strength as a card. From this viewpoint, for example, the thickness of the entire RFID tag manufacturing paper is preferably 620 μm or more at the thickest portion and 260 μm or more at the thinnest portion.

  In each of the above embodiments, the peeled layer 70 has a thickness of 95 μm, but it may not be this thickness. In order to keep the thickness of the entire RFID tag manufacturing paper within the above-mentioned thickness, the thickness of the peelable layer 70 is preferably 110 μm or less. In order to maintain the peelability, the thickness of the peelable layer 70 is preferably 80 μm or more.

  In the second embodiment, the printing layer is formed of the protective layer 21 and the heat-sensitive layer 22 formed of a known member capable of normal surface printing. good. For example, if the printing process is only heat coloring by a thermal printer or the like, the protective layer 21 does not need to be formed of a known member capable of normal surface printing. Further, for example, if it is not necessary to protect the thermal layer 22 due to the structure of a thermal printer, the protective layer 21 itself may be omitted. Conversely, a layer for surface printing and a layer for protecting the heat-sensitive layer may be provided separately.

  In each of the above embodiments, the lower layer side of the glassine paper layer 61 is sealed by the polyvinyl alcohol layer 62, but this is not essential. If there is no problem in the peelability from the peeled layer 70, the cost may be reduced by omitting the sealing by the polyvinyl alcohol layer 62.

  In each of the above embodiments, the cuts C are formed so as to penetrate the release layer 60 from the coated paper layer 20 or the protective layer 21 that is the uppermost layer. Since the cuts C only need to penetrate from the uppermost layer to the release layer 60, for example, the cuts C may partially reach the release layer 70. Further, since it is sufficient that the tag shape can be formed by peeling the layer to be peeled off 70, not all portions of the cut C need to reach the peeling layer 60 from the uppermost layer.

  In the first embodiment, the cut C has a plan view card shape. In the second embodiment, the cut C has a plan view postcard shape, but may have other shapes. For example, in any of the embodiments, the tag shape or business card shape in a narrow sense attached to an article may be used. Further, the cut C of the first embodiment may be a postcard shape, or the cut C of the second embodiment may be a card shape. In short, any shape may be used as long as it is a card shape which is a shape of a general credit card or the like, a tag shape in a broad sense including a postcard shape, a business card shape and the like.

  The RFID tag manufacturing paper is A4 size in the first embodiment, B4 size in the second embodiment, and postcard size in the third embodiment, but may be other sizes. For example, other JIS standard sizes such as row A such as A0, A1, A2, etc., row B such as B0, B1, B2, etc., Hatron size, 46 size, and chrysanthemum size may be used. In addition, any form that can be used by a general-purpose printer can be used, so even if it is not JIS standard, it is a form that is a substantial standard such as international size (letter size), postcard, cabinet size, etc. There may be.

  -Moreover, layers other than the layer laminated | stacked in said each embodiment may be further laminated | stacked. For example, a separate protective layer for improving compatibility with the print head of the printer may be laminated as the uppermost layer, or an undercoat layer for improving color development may be provided on the lower layer side of the thermal layer. .

  -Moreover, not all the layers laminated | stacked in said each embodiment are essential. For example, the polyethylene terephthalate film layer 43 and the acrylic pressure-sensitive adhesive layer 42 may be omitted if there is no particular problem in the RFID tag manufacturing paper manufacturing process. Further, if protection of the heat sensitive layer 22 is not particularly required, the protective layer 21 may be omitted and the cost may be reduced.
