Description

  The present invention relates to a non-mounting label and a method for manufacturing a non-mounting label in which the mount is removed in order to save resources.

  The adhesive paper used for seals and label products is obtained by laminating a label substrate, an adhesive layer and a separator in this order. The pressure-sensitive adhesive paper is coated with a liquid pressure-sensitive adhesive on the release agent layer side of the separator provided with a release agent layer on one side, the moisture or solvent of the adhesive is evaporated, and the label substrate is then applied to the dried pressure-sensitive adhesive layer. Created by pasting together. In addition, there is a case where the pressure-sensitive adhesive is directly applied to the label substrate and dried and then bonded to the separator. The adhesive paper prepared through such a process is slit to a predetermined width, and is processed into a label by a label printer as an adhesive base paper roll. However, since it is necessary to peel off the separator when applying this label, the removed separator becomes dust.

  In recent years, therefore, a label without a mount has been used in order to save resources and reduce garbage. FIG. 5A is a perspective view of the label roll 11 without a mount, and FIG. 5B shows a cross section taken along the line bb. The label 12 without a mount is a long strip-shaped label in which a release agent layer 14 is provided on one surface of the label base material 13 and an adhesive layer 15 is provided on the other surface. Since the adhesive layer 15 of the label base material 13 on the outer peripheral side overlaps with the release agent layer 14, the mount (separator) can be made unnecessary. As a result, there is an advantage that the mount which becomes dust after the label is used is not generated. A label without a mount is preliminarily printed between the label base material 13 and the release agent layer 14, and only this printing is used for display. Thermal paper (thermal color paper) is used as the label base material 13, and a thermal printer is used. And the like that enable thermal printing on the surface of the release agent layer 14 using a dedicated thermal transfer ribbon.

  The manufacturing method of the label without a mount will be outlined with reference to FIGS. 2, 6, and 4 in order. 2 is a schematic side view of a label processing machine 20 that performs printing and release agent coating on a label substrate, FIG. 6 is a schematic side view of a coater 100 that applies an adhesive to the label substrate, and FIG. 4 is a label substrate. FIG. 3 is a schematic side view of a slitter winding machine 150 that slits a small length to a specified length.

  The label processing machine 20 shown in FIG. 2 includes an unwinding unit 30, a back surface printing step 40, a front surface printing step 50, a release agent coating step 60, a die cutting step 70, and a winding unit 80 in the order of the paper passing path. . A label base material roll 32 obtained by winding the strip-shaped label base material 13 in a roll shape is mounted on the supply shaft 31 of the unwinding unit 30, and the label base material 13 is unwound from the supply shaft 31. The label base material 13 is guided by the guide roller 22 to reach the front surface printing process 50 from the back surface printing process 40, and then guided to the guide rolls 23, 24, 25 and 26 to reach the release agent coating process 60. In the back surface printing process 40, timing marks (not shown) are printed on the back surface of the label base material 13, and in the front surface printing process 50, characters and designs (not shown) are printed on the label base material side. In the release agent coating process 60, a release agent is applied to the surface of the label substrate 13. When characters and designs are printed, they are covered with a release agent layer 14. The label base material 13 that has been coated with the release agent is guided by the guide roller 28 and proceeds to the die cutting step 70, where processing such as providing perforations 17 at a specified pitch or forming cuts is performed. Next, the label base material 13 reaches the winding unit 80 through the guide roller 29, and is wound around the winding shaft 81 to become a peel-treated roll 82.

The peel-treated roll 82 is subjected to adhesive processing by a coater 100 shown in FIG.
The coater 100 of FIG. 6 includes an unwinding unit 110, an adhesive coating process 130, and a winding unit 140 in the order of the paper passing path.
The label base material 13 is unwound from the peeled roll 82 attached to the supply shaft 111 of the unwinding section 110 and guided to the guide roller 112 to reach the adhesive coating process 130. The pressure-sensitive adhesive coating process 130 includes a coating head 131 that discharges pressure-sensitive adhesive, a chill roll 132, and a pressure-sensitive adhesive supply tank 133. The label base material 13 subjected to the adhesive processing reaches the winding unit 140 through the guide rollers 113 and 114, and is wound around the winding shaft 141, whereby a master roll 142 of a label without a mount is obtained.

  The master roll 142 is slit to a specified width by the slitter small winding machine 150 shown in FIG. 4 and wound around the take-up shaft every specified number or length, thereby completing the label roll 11 without mount. Thus, the label 12 without mount is a resource-saving label that contributes to the protection of the forest resources that have been used as the raw material for the mount, with little waste when used in the production process.

  In many cases, a label called “strong viscosity” or “strong adhesion” is used as the pressure-sensitive adhesive 5 for the label 12 having no mount. Adhesives called strong viscosity are adhesives with high adhesive strength of 8000mN / 25mm (180 degree peeling adhesive strength to JIS Z 0237 test plate) or more, and permanent adhesive use that does not peel off after being applied It is.

  However, labels with low adhesive strength are also required. When there is a possibility of peeling off after being attached to the adherend, an adhesive called “weak viscosity” having low adhesive strength is used. This is because when affixed to an adherend such as corrugated cardboard, the label can be peeled without damaging its surface. Further, in the case of using it to peel from the adherend (for example, a delivery slip label with a receipt), an adhesive called “re-peeling” having a lower adhesive strength is used. When manufacturing these label without a mount, the adhesive of the coater is changed to “weak viscosity” or “re-peeling”. The same applies to the pressure-sensitive adhesive called “micro-adhesion” based on the application to be applied to a smooth surface such as glass and peeled off.

  However, as the adhesive, an adhesive having a low adhesive strength such as “weak viscosity” or “re-peeling” having an adhesive strength of 15 to 5000 mN / 25 mm (180 degree peeling adhesive strength to the JIS Z 0237 test plate) was used. When the label without a mount is attached to the adherend and then peeled off, the adhesive may remain on the adherend, so-called “glue residue” may occur. This is because the adhesive having a weak adhesive strength is not only weakly adhered to the adherend but also has low adhesion to the label substrate.

  The above-mentioned “glue residue” phenomenon is caused by the circumstances peculiar to the non-mounting label. The label without a mount is once wound up into a roll after the release agent is applied, and in the roll state, the surface on which the release agent is applied and the surface on which the adhesive is to be applied contact. During the period of contact, free silicone contained in the release agent and unreacted monomers that have not been fully cured after being irradiated with ultraviolet light have been transferred to the back side of the base material, resulting in the back side of the label base material. It becomes a state where a small amount of release agent is applied. Even if it is a trace amount release agent, when an adhesive is applied on it, the adhesiveness of an adhesive and a label base material will fall. When "strong viscosity" with high adhesive strength is applied as an adhesive, the adhesiveness reduction between the adhesive and the label substrate can be ignored, but adhesion with low adhesive strength such as "weak viscosity" or "re-peeling" In the case of the agent, the adhesion to the label base material is insufficient, and when the label is peeled off from the adherend, it causes a problem called “glue residue” in which the adhesive adheres to the adherend side.

  As a countermeasure, the above problem can be solved by connecting the label processing machine and the coater, and applying the adhesive without winding after applying the release agent, but the optimal application conditions for the release agent and the adhesive It is necessary to match coating conditions (such as coating speed). It is a highly productive method if conditions are met, but labels are often produced in small quantities and a variety of products with different designs and sizes for each user, so the work to change the design printed on the label surface, so-called plate change and blade type Each time the exchange is performed, the entire line needs to be stopped, and there is a concern about a decrease in productivity.

JP 2003-036026 A

  The present invention has been made to solve the above-described problems, and even when the adhesive strength is low such as weak viscosity or re-peeling, when the label is peeled off from the adherend, it can be removed cleanly without leaving an adhesive. It is an object to provide a label without a mount and a method for manufacturing a label without a mount.

The mountless label of the present invention made to solve the above problem is a mountless label in which a release agent layer is formed on the surface of a label substrate and an adhesive layer is formed on the back surface, and the label substrate and the adhesive Between the layers, a resin film layer that covers the adhesion inhibitor adhered to the back surface of the label base material is formed, and the pressure-sensitive adhesive layer is provided so as to overlap the resin film layer.
In addition, the method for producing a label without a mount according to the present invention is to form a label base roll by coating a release agent on the surface of a long strip-shaped label base material and providing a release agent layer, and then winding the label base roll. Unwinding the label base material from the label base material roll, coating the back surface of the label base material with an ultraviolet curable resin and irradiating with ultraviolet light to form a resin film layer, It includes a step of coating an adhesion inhibitor and a step of forming a pressure-sensitive adhesive layer by applying a pressure-sensitive adhesive on the resin film layer in this order.
In the label without a mount and the method for producing a label without a mount of the present invention, it is desirable that the adhesive has an adhesive strength of 15 to 5000 mN / 25 mm (180-degree peeling adhesive strength to a JIS Z 0237 test plate).
In particular, it is effective for an adhesive having an adhesive strength of 100 to 4000 mN / 25 mm (180-degree peeling adhesive strength with respect to a JIS Z 0237 test plate).
A thermal paper having a thermosensitive coloring layer on the surface can be used as the label substrate.

  The label without a mount of the present invention can be peeled cleanly from the adherend after being attached to the adherend. In particular, even when a low-viscosity or re-peeling adhesive having low adhesive strength is used as the adhesive, the label can be peeled off without the adhesive remaining on the adherend. Further, according to the method for processing a label without a mount according to the present invention, a label without a mount capable of peeling the label without leaving an adhesive residue even when a low-viscosity or low-peeling adhesive with low adhesive strength is used. Can be manufactured.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows a mountless label 2 of the present invention. FIG. 1A is a perspective view of a mountless label roll 1 in which a continuous body of mountless label 2 is wound, and FIG. 1B is a line bb of a mountless label 2 unwound from the mountless label roll 1. It is sectional drawing. This mountless label 2 is provided with a release agent layer 4 on one side of a label substrate 3 and a resin film layer 6 and an adhesive layer 5 on the other side in this order. A perforation 7 for separating the non-mounting label 2 for each unit is formed in the continuous body of the non-mounting label 2. In many cases, the label 2 without mount is wound around a branch pipe and provided as a label roll 1 without mount.

  Between the label base material 3 and the resin film layer 6, a timing mark 8 for detecting one unit of label is printed when the continuous body of the label 2 without mount is run by a label printer or an automatic sticking machine. Yes. Further, before the release agent layer 4 is formed between the surface of the label base material 3, that is, the release agent layer 4, an image 9 such as a product name, code, price, date, company name, etc., as necessary. May be printed.

  The type and material of the label substrate 3 are not particularly limited, such as paper or synthetic resin film, and are generally used as adhesive paper. For example, paper materials such as thermal paper (paper-based thermal paper), fine paper, coated paper, art paper, PET (polyethylene terephthalate), PE (polyethylene), PP (polypropylene), PS (polystyrene) A synthetic resin film, a sheet obtained by combining a plurality of the above-mentioned synthetic resins, a thermal paper based on the synthetic resin sheet or film, and a composite sheet obtained by combining a synthetic resin film and paper can also be used.

  As the release agent used for the release agent layer 4, for example, ultraviolet curable silicone, thermosetting silicone, solvent-type silicone, alkyl pendant polymer, fluorine-based release agent, and compositions containing them are used. Is possible.

  The pressure-sensitive adhesive used for the pressure-sensitive adhesive layer 5 is, for example, an emulsion system (in which the pressure-sensitive adhesive is dispersed in water), a solvent system (in which the pressure-sensitive adhesive is dissolved in a solvent), a hot melt system (using thermoplasticity), or the like. It is. Examples of the material include adhesives such as synthetic rubber, natural rubber, acrylic resin, polyvinyl ether resin, urethane resin, and silicone resin. The hot melt adhesive may be rubber or acrylic. It is also possible to use an ultraviolet curable pressure-sensitive adhesive that is cured by irradiation with ultraviolet rays after coating (to achieve chemical stabilization). The pressure-sensitive adhesive properties of the pressure-sensitive adhesive are arbitrary, such as so-called slight adhesion, re-peeling, weak viscosity, standard glue, medium viscosity, strong viscosity, super-strong viscosity, frozen glue, polyolefin, rough surface, and tire. What is necessary is just to select according to the kind of to-be-adhered body. Furthermore, the viscosity of the pressure-sensitive adhesive when applied to the label base material 3 is preferably such that the pressure-sensitive adhesive does not ooze onto the surface of the label base material 3 through the perforations 7. For example, it is 500 cps or more, preferably 3000 cps or more. When an adhesive having this viscosity is applied, the adhesive does not ooze out on the surface of the label substrate 3.

For the resin film layer 6, for example, an ultraviolet curable resin is used. An ultraviolet curable varnish or an ultraviolet curable medium can be used, and a film forming method is arbitrary. An ultraviolet curable printing ink can also be used. These resins may be applied using a coater or printed by a printing machine. When printing with a printing machine, printing may be performed using a solid roll or a solid plate, or using a halftone plate. However, when halftone printing is performed, the image area is set to 70% or more.
By providing and coating the resin film layer 6 on the back surface of the label base material 3, free silicone and unreacted monomers, low molecular weight components, liquid form, etc. that have been transferred from the release agent layer 4 to the back surface of the label base material 3 The ingredients are covered and subsequently cured. By this operation, the back surface of the label substrate 3 is modified to a surface on which the pressure-sensitive adhesive easily adheres.

  Next, the manufacturing method of the mountless label 2 of this invention is demonstrated using FIGS. 2 is a schematic side view of a label processing machine 20 that performs printing and release agent coating on a label substrate, FIG. 3 is a schematic side view of a coater 100 that applies an adhesive to the label substrate, and FIG. 4 is a label substrate. FIG. 3 is a schematic side view of a slitter winding machine 150 that slits a small length to a specified length.

  As shown in FIG. 2, a long strip-shaped label base material 3 wound in a roll shape is attached to the supply shaft 31 of the unwinding unit 30 of the label processing machine 20. The label base material 3 unwound from the supply shaft 31 is guided by a large number of guide rollers 22, 23... 29, while the back surface printing process 40, the front surface printing process 50, the release agent coating process 60, and the die cutting process 70. After that, it is wound around the winding shaft 81 of the winding portion 80. Hereinafter, each step will be described.

  The back surface printing step 40 is a step of printing on the back surface of the label substrate 3 unwound from the supply shaft 31 and includes a printing unit 41. The printing unit 41 includes a plate cylinder 42 on which a plate is wound, an impression cylinder 43, and a UV lamp 44. The printing cylinder 41 sandwiches and conveys the label base material 3 between the plate cylinder 42 and the impression cylinder 43, and the plate cylinder 42. An ultraviolet curable ink (ink cured by irradiation of ultraviolet rays) is supplied to the surrounding plate to perform printing on the back surface of the label substrate 3. Then, the printed ink is cured by irradiating ultraviolet rays from the UV lamp 44. Thereby, as shown in FIG. 1, the timing mark 8 is printed on the back surface of the label base material 3.

  In the next surface printing step 50, printing is performed on the surface of the label substrate 3 to form an image 9. The printing unit 51 includes, for example, a plate cylinder 52 wound with a plate, an impression cylinder 53, and a UV lamp 54. Since each operation is the same as that of the back surface printing step 40, detailed description is omitted. Printing units for the back surface printing process and the front surface printing process are prepared in accordance with the presence or absence of timing marks and the number of colors for front surface printing.

  The release agent coating step 60 is a step of applying a release agent to the surface of the label substrate 3 that has undergone the surface printing step 50. The type of release agent and the release effect are selected according to the type of pressure-sensitive adhesive used in the pressure-sensitive adhesive coating step 20 described later. For example, a release agent mainly composed of silicone is used. This release agent is applied to the surface of the label substrate 3 by a coating unit 61 having a coating roll 62 and a backup roll 63, and is cured by irradiating ultraviolet rays from a UV lamp 64. As a result, a release agent layer 4 is formed on the surface of the label base 3 as shown in FIG.

  The die cutting step 70 is a step of forming perforations and cuts in the label base material 3 that has undergone the release agent coating step 60, and includes a die roll 71 and an anvil roll 72. A perforation 7 penetrating the label base material 3 and the release agent layer 4 is formed by pressing the die roll 71 against the label base material 3 and rotating it.

  The label base material 3 that has undergone the die-cutting process 70 is taken up by the take-up shaft 81 of the take-up unit 80 and becomes a release-treated roll 82. The peel-treated roll 82 is removed from the take-up shaft 81 and transferred to the coater 100 shown in FIG.

  While the label base material 3 is wound as the release-treated roll 82, the surface release agent layer 4 is in contact with the back surface of the label base material 3. During the period of contact, transfer of an adhesion inhibitor such as free silicone, unreacted monomer, low molecular weight component, and liquid component occurs from the release agent layer 4 to the back surface of the label substrate 3.

  The coater 100 shown in FIG. 3 includes an unwinding unit 110, a resin film forming step 120, an adhesive coating step 130, and a winding unit 140.

  The unwinding unit 110 includes a supply shaft 111 that unwinds the unrolled roll 82 by pivotally supporting it. The label base material 3 unwound from the supply shaft 111 is transferred to the resin film forming step 120 through the guide roller 112.

  The resin film forming step 120 is a step of forming a resin film layer 6 by applying a resin to the back surface of the label substrate 3 and curing it. For example, an ultraviolet curable resin is used as the material of the resin film layer 6. Specifically, an ultraviolet curable varnish or an ultraviolet curable medium can be used. For the application of the ultraviolet curable resin, for example, a coating unit 121 including a coating roll 122, a backup roll 123, and a UV lamp 124 is used. An ultraviolet curable resin is applied with the coating roll 122, and the resin film layer 6 shown in FIG. The adhesion inhibitor is coated and sealed between the resin film layer 6 and the label substrate 3. During coating, the resin film layer 6 is sandwiched between the coating roll 122 and the backup roll 123 and is in close contact with the label base 3 while receiving pressure. Will not be repelled. Free silicone and unreacted monomer on the backside of the substrate is not enough to form a film, so it can be covered with a medium such as a medium. A film is formed.

  Here, the film formation method of the resin film layer 6 is arbitrary. Coating may be performed using a coater, or printing may be performed using a printing machine. When printing with a printing machine, printing may be performed using a solid roll or an endless plate, or using a halftone plate. However, when halftone printing is performed, the image area is set to 70% or more. When it is less than 70%, a sufficient covering effect cannot be obtained. The label substrate 3 that has undergone the resin film forming step 120 is transferred to the next pressure-sensitive adhesive coating step 130.

  The pressure-sensitive adhesive coating process 130 includes a coating head 131 that discharges a hot-melt pressure-sensitive adhesive, a chill roll 132, and a pressure-sensitive adhesive supply tank 133. When the hot-melt adhesive 5 in the adhesive supply tank 133 is discharged from the tip of the coating head 131 to the surface of the resin film layer 6, the adhesive layer 5 is formed. The pressure-sensitive adhesive 5 is strongly adhered to the resin film layer 6 and is firmly adhered to the back surface of the label substrate 3 through the resin film layer 6. The label base material 3 on which the pressure-sensitive adhesive layer 5 is formed is wound around the winding shaft 141 of the winding portion 140 through the guide rollers 113 and 114 to become a master roll 142.

  The master roll 142 is transferred to the slitter roll 150 shown in FIG. The slitter small winding machine 150 includes an unwinding unit 160, a slitting process 170, and a winding unit 180.

  The unwinding unit 160 includes a supply shaft 161 that unwinds the master roll 142 while pivoting it. The label substrate 3 unwound from the supply shaft 161 is sent to the slit process 170 through the guide rollers 151 and 152. The slit process 170 includes a pair of rotary blades of an upper blade 171 and a lower blade 172, and an operation of slitting the label base material 3 into a desired width and row is performed. FIG. 4 shows a state divided into two columns. After the slitting operation, the paper is fed to the winding unit 180 through the guide roller 153, and is wound up by a specified number of branches or a specified length on a branch pipe having a specified width to complete the label roll 1 without mount.

  The mountless label roll 1 manufactured as described above is cut off at the perforation 7 and attached to the adherend as the mountless label 2 for use. When the label substrate 3 is thermal paper and printing is performed using a label printer (not shown), the label base 3 may be cut with a cutter attached to the printer.

  The mountless label 2 of the present invention can be peeled cleanly from the state of being attached to an adherend. The pressure-sensitive adhesive 5 is applied to the surface of the resin film layer 6 and is in close contact with the back surface of the base material through the cured film, so that the pressure-sensitive adhesive layer 5 has an adhesive force called slight adhesion, re-peeling, and weak viscosity. Even if it is weak, the pressure-sensitive adhesive layer 5 is peeled off cleanly while staying on the label substrate 3 side. The so-called adhesive residue phenomenon in which the adhesive remains on the adherend side does not occur.

  Further, according to the method for producing a label without a mount according to the present invention, a label without a mount that can be peeled cleanly from an attached substrate even when the adhesive is weakly adhering, called weak adhesion, re-peeling, and weak viscosity. Can be provided.

  It should be noted that the present invention is not limited to the above-described embodiments, and it is obvious that each embodiment can be appropriately changed within the scope of the technical idea of the present invention. In addition, the number, position, shape, arrangement, and the like of the above-described constituent members are not limited to the above-described embodiment, and can be set to a suitable number, position, shape, and the like in practicing the present invention.
