Description

  The present invention relates to an attention label manufacturing method and an attention label comprising the manufacturing method.

  Conventionally, in the manufacture of POP (Point of Purchase) labels and attention labels to be attached to products, it has been common to apply varnish to the glue surface and dry it to remove the adhesiveness of the glue. As a result, adhesiveness appeared, and there was a problem in terms of quality such as adhesion of dust. In addition, in the case of such a label, it is also a problem that it is warped (curled) when finished. In order to solve these problems, it is effective to use a label with a specification that completely eliminates stickiness by inserting and bonding a film on the glue surface (adhesive surface).

  As a label having a specification for completely eliminating the adhesiveness by inserting and bonding a film on such a glue surface, for example, a label as disclosed in Japanese Patent Application Laid-Open No. 2007-293081 (Patent Document 1) is disclosed. .

  The label described in Patent Document 1 describes portions to be expressed on the upper base material and the lower base material, and an adhesive layer (adhesive layer) is provided between the upper base material and the lower base material. The upper base material is a label that is hard to bend when finished or in use by being attached with an embossed and metal-deposited film.

  However, the label described in Patent Document 1 must be appropriately non-adherent in adhesiveness (tackiness) after label production, depending on how the adhesive layer is installed, separately from the label production process. In the past, including the label described in Patent Document 1, the label printing process and the bonding of the insertion film, the punching process, and the scrap raising process were manufactured in separate processes, and thus finished as a product. At times, there was a problem that it was easy to curl.

  On the other hand, with regard to correction of label curl, for example, Japanese Patent Application Laid-Open No. 10-119942 (Patent Document 2) discloses a label curl correction apparatus. However, when using a curl correcting device as described in Patent Document 2, it must be used separately from the label manufacturing process, and used for a label as described in Patent Document 1. Then, it is not considered that the adhesiveness is removed by inserting the insertion film on the glue surface, and that the tension or curl of the insertion film is not considered.

JP 2007-293081 A JP-A-10-119942

  In view of the above circumstances, the present invention can improve the productivity and reduce the manufacturing cost by enabling inline manufacturing of the label printing process and the bonding, punching process, and scrap raising process of the insertion film. The present invention provides an attention label manufacturing method and an attention label using the manufacturing method.

  The above-mentioned object of the present invention is that after the label printing step, the upper paper and the release paper adhered by the adhesive layer from a tack paper comprising an upper paper provided with an adhesive layer on at least one side and a release paper. A peeling step, and after the peeling step, an insertion film is inserted and bonded between the upper paper and the release paper, and a tack paper in which the insertion film is bonded. A method for producing an attention label comprising a blanking step, a dregs raising step, and a roll finishing step for in-line work, wherein in the laminating step, the tension of the upper paper And the tension of the insertion film is adjusted at the same time, the upper paper, the insertion film and the release paper are bonded together, and the upper paper is Is accomplished by contacting the bonding rollers bonding is installed to a member for use in conjunction step.

  In addition, the object of the present invention is to provide a cutting step in which the bonding step is cut in a continuous pattern shape, and in the cutting step, the adhesiveness of the adhesive layer is erased. Is achieved more effectively.

  Also, the above object of the present invention is achieved by an attention label comprising the above manufacturing method.

  According to the method of the present invention, a film can be bonded to an adhesive at the same time as printing, and it is possible not only to completely remove the adhesiveness of a part of the target adhesive layer, By making the tension of the insertion film the same, the label is warped, that is, curling can be prevented, and the manufacturing cost can be kept low.

The line 1 includes a label printing device 2, a peeling machine 4 for peeling the upper paper and the release paper on the tack paper 3 printed by the label printing device 2 up and down, and an upper paper pass line composed of the upper paper. 5, a release paper pass line 6 made of the release paper, an insertion film pass line 7 provided between the upper paper pass line 5 and the release paper pass line 6, the upper paper, the insertion film, and the release paper The laminating member 8 for laminating and laminating in order, the punching part 9 for punching, the scrap raising part 10, and the roll finishing part 11 for winding the manufactured attention label are one line. (Inline). The label printing apparatus 2 is not particularly limited, and may be a conventional printing apparatus as long as something can be printed on a tack paper composed of an upper paper provided with an adhesive layer and a release paper. Moreover, the peeling machine 4 may be a conventional peeling apparatus.

  Next, the upper paper pass line 5 and the release paper pass line 6 will be described. Here, the upper paper pass line refers to the upper paper itself related to the tack paper peeled off by the peeling machine 4, but here it is defined as “upper paper pass line 5” for explanation as a production line. Similarly, the release paper pass line 6 refers to the release paper itself relating to the tack paper peeled off by the release machine 4, but here it is defined as “release paper pass line 6” for explanation as a production line. As shown in FIG. 1, when production is taken into consideration, the upper paper pass line 5 and the release paper pass line 6 are both provided with a conveyor roll 12 and a dancer roll 13 so as to be formed as lines. There are no particular restrictions on the arrangement of these, and there is no particular restriction on the shape and the like.

  Next, the insertion film pass line 7 will be described.

  First, the insertion film pass line 7 refers to the insertion film itself as in the case of the upper paper pass line 5 and the release paper pass line 6. 7 ”. As shown in FIG. 1, the insertion film pass line 7 includes a one winder 14 around which an original film of the insertion film is wound, a conveyor roll 12 for establishing the insertion film as a line, and a load cell 15. Become. About the one winder 14, the roll 12 for conveyors, and the load cell 15, a commercially available apparatus may be sufficient. Although not shown, the one winder 14 is equipped with a brake for controlling the feeding speed of the insertion film pass line 7, that is, the rotational speed of the one winder 14. A tension controller 15 ′ is installed so as to be linked (connected) to the one winder 14 and the load cell 15. There is no particular limitation on the installation method of the tension controller 15 '. The tension controller 15 'may be a commercially available device.

  Here, when a plurality of one winders 14 are used in the insertion film pass line 7, the one winders may be connected to each other via a spacer 20 made of a metal tube, as shown in FIG. At this time, as shown in FIG. 2B, it is more effective to press both ends of the one winder with the presser panel 21. The shape of the presser panel 21 is not particularly limited.

  Further, the insertion film pass line 7 may be provided between the upper paper pass line 5 and the release paper pass line 6 as shown in FIG. The insertion film pass line 7 is not connected to the label printing apparatus 2.

  The upper paper pass line 5, the insertion film pass line 7 and the release paper pass line 6 are laminated in the bonding member 8 so that the upper paper, the insertion film, and the release paper are laminated in this order. The roller 12 'is touched and pasted together. The roller 12 'may be a commercially available product. In addition, when adopting a pattern cut such as a corrugated shape of the label, as shown in FIG. 3, in the insertion film pass line 7, between the load cell 15 and the bonding member 8, A cutter 17 may be installed. About the cutter 17, what is necessary is just to match | combine the conventional apparatus with the shape of a pattern cut suitably. Incidentally, in FIG. 3, the reference numerals other than the cutter 17 are the same as those in FIG.

  Next, the attention label line 16 comprising the upper paper pass line 5, the insertion film pass line 7 and the release paper pass line 6 is then connected to the punching section 9, the scrap raising section 10, and the roll winding section 11, The desired attention label in the invention is manufactured.

  Next, an attention label manufacturing method according to the present invention will be described with reference to the flowchart of FIG. Moreover, it demonstrates using FIG. 1 thru | or FIG. 3 as needed.

  First, printing is performed in advance on the upper surface of an adhesive paper (adhesive) layer having an adhesive (adhesive) layer on at least one side and a tack paper label made of release paper (step S0, start). The tack paper label is manufactured in advance by a conventional method. When it is desired to decorate the surface of the upper paper with a pattern or the like, a conventional method is used in advance. Further, the conventional technology may be used for printing on the label. The material of the adhesive layer is not particularly limited, and a general-purpose adhesive (preferably a highly viscous type) may be used.

  Next, in the tack paper label, the upper paper and the release paper are peeled up and down by the peeling machine 4 as shown in FIG. 1 or 3 (step S1). At this time, the tension of the upper paper may be controlled. Conventional tension controls can be used as appropriate. Moreover, there is no restriction | limiting in particular about the material of the upper paper to be used, such as a polyethylene terephthalate (PET) and a synthetic paper. The synthetic paper referred to here includes, for example, YUPO (registered trademark) manufactured by YUPO Corporation.

  In parallel with step S1, the tension of the laminated (insertion) film is controlled using the tension controller 15 'shown in FIG. 1 or FIG. 3 (step S21). Furthermore, when considering pattern cuts such as corrugations, a step of cutting patterns (step S22) may be added after step S21 as shown in FIG. 2 (of course, step S22 may be omitted). ). At the time of pattern cutting, for example, the shape of the cutter 17 can be selected as appropriate. In this step S22, part of the adhesiveness of the upper paper can be erased.

  Here, the material of the insertion film used is the above-mentioned synthetic paper, high-density or low-density polypropylene (PP), stretched propylene (OPP), stretched or vapor-deposited polyethylene terephthalate (PET), or silver or gold. Examples include glossy finish, but there is no particular limitation.

  As shown in FIG. 1 or FIG. 3, the upper paper and release paper peeled up and down in step S1 and the insertion film tension-controlled in step S21 are laminated in the order of the upper paper, the insertion film, and the release paper. Then, the pasting members 8 are pasted again so as to become tack paper labels (step S3). In FIG. 5 (A), when one inserting the winder 14 is used in FIG. 5 (A), the state (outline) of the bonding of the insertion film 7 and the release paper 6 in this step S3 is shown. The case of using a plurality of one winders 14 is also shown in FIG. When the upper paper, the insertion film, and the release paper are bonded together, it is preferable that the upper paper is in contact with the bonding roller 12 ′ illustrated in FIG. 1 or 3. When the upper paper is not in contact with the laminating roller 12 ', there is a problem that the entire label is curled or bubbles are introduced after the attention label is manufactured.

  The tack paper label in which the film for insertion bonded again in step S3 is inserted is punched (step S4). The punching process in step S4 is a process of half-cutting the tack paper label in which the insertion film is inserted. The punching process may be a conventional method. In FIG. 5 (B), when one upper winder 14, the insertion film 7 and the release paper 6 are pasted together in this step S4 (schematic), when one single winder 14 is used, two two winders 14 are used. It is shown as a case where it is used (refer to FIG. 2 for the case where a plurality of one winders 14 are used).

  After step S4, an attention label as shown in FIG. 6 is manufactured through a residue raising step (step S5) and a roll finishing step (step S6) (FIG. 6 will be described later). It should be noted that in FIG. 5C, when one upper winder 14, the insertion film 7 and the release paper 6 are bonded together (schematically) in FIG. 5 (C), one two winder 14 is used. It is shown as a case where it is used (refer to FIG. 2 for the case where a plurality of one winders 14 are used).

  As described above, according to the attention label manufacturing method of the present invention, the steps S0 to S6 can be performed in-line, so that it is easy to extend on the upper paper and cause curling. By using a plurality of laminating films and unwinders, a stable label can be produced even with a thin laminating film.

  Next, an attention label using the attention label manufacturing method according to the present invention will be described with reference to FIG.

  FIG. 6A is an overall schematic diagram illustrating an example of an attention label as a product. The attention label 30 has a part of the upper paper 5 'standing in the B direction (the arrow direction indicated by the broken line) with the broken line D as a boundary, and the other part of the upper paper 5' is attached to the insertion film 7 'by an adhesive. It is glued.

  Next, FIG. 6B is a cross-sectional view taken along a broken line A-A ′ shown in FIG. 6A in the embodiment shown in FIG. As shown in FIG. 6B, when the upper paper 5 'is the upper part, the insertion film 7' is laminated in the middle and the release paper 6 'is laminated on the lower part. At this time, the back surface C of the upper paper 5 'is in a state where the adhesiveness has been lost. In this embodiment, the adhesiveness of the back surface C is lost, but the attention label according to the present invention is established even if the adhesiveness of the back surface C is not lost.

  Here, the material used as the upper paper 5 'is not particularly limited, such as polyethylene terephthalate (PET) and synthetic paper as described above. The upper paper preferably has a thickness of about 10 to 100 μm.

  Moreover, as a material used as the film 7 'for insertion, synthetic paper as described above, high density or low density type polypropylene (PP), stretched propylene (OPP), stretched or vapor-deposited polyethylene terephthalate (PET), and those A silver or gold-finished one can be used, but there is no particular limitation. The thickness of the insertion film is 10 to 100 μm, preferably 20 to 80 μm. If the thickness is 10 μm or less, the tension may not be controlled at the time of production or may be broken in the middle. Further, when the thickness is 100 μm or more, a problem of tension control or the like occurs.

  Next, FIG. 6C is a schematic view showing the surface of the insertion film 7 ′ when the upper paper 5 ′ is peeled off. In the above-described manufacturing method, in the step S4, the insertion film 7 as shown by the dotted lines in the symbols shown in FIG. 6A (the portions indicated by ◎ and ○ in FIG. 6A) is shown. It is the mechanism shown on the surface of '.

  Although the attention label according to the present invention has been described above, it is needless to say that the present invention is not limited to the above-described embodiment, and various embodiments can be adopted as long as they do not depart from the scope of the claims.

  Hereinafter, an Example is described about the attention label manufactured based on embodiment described above. In describing this embodiment, the items described in FIG. 1 or FIG. 3 may be used as necessary.

Example 1 Manufacture of an Attention Label Using the Manufacturing Method According to the Present Invention First, an attention label was manufactured using an attention label manufacturing line as shown in FIG. The manufacturing conditions are shown in Table 1 below. At this time, the release paper pass line 6 (release paper) is not considered in this embodiment.

  In Table 1, first, as the upper paper, PET (polyethylene terephthalate) and synthetic paper (for example, YUPO YUPO (registered trademark) manufactured by Corporation was used) (see Comparative Examples 1 to 8 and Examples 9 to 22 in Table 1). In addition, as the adhesive layer (pressure-sensitive adhesive layer) provided on the upper paper, a general-purpose adhesive of strong viscosity type was used.

  Next, as Comparative Examples 1 to 8 and Examples 9 to 22 as insertion (bonding) films, stretched PP (polypropylene) (two types of 20 μm and 40 μm), PET (polyethylene terephthalate) (50 μm and 25 μm) 2 types), vapor deposition (silver luster processing) PET (in Table 1, as vapor deposition PET, 2 types of 50 μ and 25 μ) and 7 types of synthetic paper (same as the above-mentioned upper paper) 80 μ were used.

  Here, “tension adjustment of the insertion film” in Table 1 refers to tension adjustment by the tension controller 15 ′ shown in FIG. 1 or 3, and “contact between the upper sheet and the bonding roll 12 ′. "" Means a state in which the upper sheet is in contact with the bonding roll 12 'shown in FIG. 1 or FIG. Further, “the state in which the upper paper and the bonding roll 12 ′ are not in contact” means that the bonding roll 12 ′ is not built in the bonding member 8 shown in FIG. 1 or FIG. This refers to the state in which the top paper and the film for insertion are pasted together. Table 1 shows an attention label according to the present invention, that is, Examples 9 to 22, in which both “tension adjustment of the film for insertion” and “contact between the upper paper and the bonding roll 12 ′” are formed. ing. Further, Comparative Examples 1 to 8 show only one of “adjustment of the tension of the film for insertion” and “contact between the upper paper and the bonding roll 12 ′”.

  Based on the conditions such as the base material as described above (see Table 1), the speed of the production line (each line shown in FIG. 1 or FIG. 3) is 35 m / min, 40 × 40 mm, and the film is attached 25 mm. A 40 mm attention label was produced.

[Example 2] Quality verification test of attention label manufactured in Example 1 With respect to the attention label obtained in Example 1 above, a quality verification test was performed for Comparative Examples 1 to 8 and Examples 9 to 22. It was. In addition, about Comparative Examples 1-8 and Examples 9-22, it is the same as that of Table 1 in the said Example 1. FIG.

  As a quality verification test, “defect after manufacture”, “sticking to container” and “film peeling for insertion” were tested.

  First, regarding “problems after production”, the presence of bubbles or curls was visually confirmed in Example 1 when the upper paper and the film for insertion were bonded.

  For “sticking to the container”, the label according to each comparative example or each example attached to a cylindrical container with a diameter of 50 mm was left in an environment of a temperature of 60 ° C. and a humidity of 90% for one week, The floating of the label from the cylindrical container was visually confirmed.

  For “insertion film peeling”, the label for insertion according to each comparative example or each example was allowed to stand for 1 week in an environment of a temperature of 60 ° C. and a humidity of 90%, and the peeling of the insertion film was visually confirmed. .

  The results of the quality assurance test described above are shown in Table 2 below.

  First, regarding “sticking to a container”, Comparative Examples 1 to 8 and Examples 9 to 22 were “good”, that is, no label peeling was confirmed.

  Next, regarding “insertion film peeling”, “None” in all of Comparative Examples 1 to 8 and Examples 9 to 22, that is, no peeling of the insertion film was confirmed.

  And about the malfunction after manufacture, in Examples 9-22, although it was "good", ie, a bubble and a curl were not confirmed, in a comparative example, a curl (refer comparative examples 1-4) and a bubble (comparative example) 5-8) was confirmed.

  From the above, the two technical features relating to the attention label manufacturing method of the present application are “the tension of the upper paper and the tension of the insertion film are adjusted simultaneously” and “the upper paper is used in the bonding process. It is possible to achieve the object of the present invention, such as preventing curling and air bubbles, by simultaneously having "contacting a bonding roller installed (built-in) in a bonding apparatus (bonding unit)". I understood.

  Therefore, it was concluded that there is no quality problem in the attention label manufactured by the manufacturing method of the present invention.

Although the embodiment has been described above, the embodiment according to the present invention is not limited to this.
