However, the roll-shaped label paper disclosed in Cited Document 1 has a problem that the label is torn and difficult to use when the label attached to the release paper is peeled off in the scene where the label is actually attached to the product. In addition, when the product is liquor, if the label is directly attached to the liquor bottle, the water droplets generated on the liquor bottle may cause the label to become damp, shrink, or wrinkle. Therefore, further improvement of the roll-shaped label paper is required. Therefore, the present invention provides a roll-shaped label paper and a method for manufacturing a roll-shaped label paper, which can cleanly peel off the label and improve the convenience that the attached label does not shrink or wrinkle due to water droplets. ..

The roll-shaped label paper of the present invention is attached to the core material wound in a roll shape, the adhesive applied to both sides of the core material, and the adhesive on one side of the core material arranged at equal intervals. Includes the label and the release paper affixed onto the adhesive on the other side of the core. As a result, since the label is attached on the adhesive applied to one surface of the core material, it is not affected by the release paper when it is peeled off, as compared with the case where the label is attached on the release paper. Further, when a label is attached to a product, the label is not directly attached to the product because it is attached to the product by the adhesive applied to the other surface of the core material.

Further, it is desirable that the core material of the roll-shaped label paper of the present invention is a polyester film. This causes the label to be affixed onto an adhesive applied to one side of a polyester film that has tensile strength and is hydrophobic.

Further, in the roll-shaped label paper of the present invention, the labels are printed on a plurality of sheet-fed special papers for labels in which the end faces are butted against each other, and the end faces of the sheet-fed special papers are printed on each other. It is desirable that there is no label printed on the end face portion where the labels are abutted. Not all special label papers of paper quality are in the form of rolls or continuous sheets in advance, and many special papers for labels are in the form of sheets. Therefore, this makes it possible to use special paper for labels of any paper quality as the roll-shaped label paper. Further, this makes it possible to provide a roll-shaped label paper excluding a label having a label printed on an end face portion (a defective label that cannot be attached to a product).

The method for producing a roll-shaped label paper of the present invention includes a step of applying an adhesive on both sides of a core material wound into a roll shape, and a special method for a plurality of sheet-fed labels on the adhesive on one side of the core material. The process of sticking the paper by butting the end faces against each other, the step of sticking the release paper on the adhesive on the other side of the core material, and the label printing on the special label paper at equal intervals, only the label part The label obtained by the partial cutting is arranged and attached at equal intervals on the adhesive on one side, and the label is peeled off on the adhesive on the other side. It includes a step of winding a core material to which paper is attached into a roll. As a result, the label is attached on the adhesive applied to one surface of the core material, and the label is not affected by the release paper when it is peeled off, as compared with the label attached on the release paper. Label paper can be produced. In addition, when a label is attached to a product, a roll-shaped label paper should be prepared so that the label is not directly attached to the product because it is attached to the product by the adhesive applied to the other surface of the core material. Can be done. The plurality of sheet-fed special papers for labels are attached to the other surface of the core material with an adhesive.

Further, the method for producing a roll-shaped label paper of the present invention includes an end face portion in which the end faces of the sheet-fed special paper for labels are butted against each other before or after label printing is performed on the special label paper at equal intervals. Includes a step of peeling the label. This makes it possible to provide a method for producing a roll-shaped label paper excluding a label having a label printed on an end face portion (a defective label that cannot be attached to a product).

(1) According to the roll-shaped label paper and the method for producing the roll-shaped label paper of the present invention, the label is stuck on the adhesive applied to one surface of the core material, and therefore is stuck on the release paper. Rather than being peeled off, it is not affected by the release paper and can be peeled off cleanly without tearing. In addition, when the label is attached to the product, the adhesive applied to the other surface of the core material is attached to the product, so the label is not directly attached to the product and is not affected by water droplets. You can prevent it from shrinking or wrinkling.

(2) The label is more difficult to tear and more resistant to moisture due to the structure using a polyester film having tension and hydrophobicity in the core material.

(3) Labels are printed on a plurality of sheet-fed special papers for which the end faces are butted against each other, and labels are printed on the end faces where the end faces of the sheet-fed special paper for labels are butted against each other. With the configuration in which is not present, it is possible to use special paper for labels of all paper qualities, and it is possible to provide roll-shaped label paper excluding defective labels that cannot be attached to products. Further, since the release paper is attached to the other surface of the core material, it is not necessary to attach the end faces to each other with a single-sided adhesive tape.

Hereinafter, embodiments of the present invention will be described in detail, but the description of the constituent elements described below is an example (representative example) of the embodiments of the present invention, and the present invention is described below unless the gist thereof is changed. It is not limited to the contents of.

[Roll label paper]
FIG. 1 is an explanatory diagram showing a structure before label printing and partial cutting are performed on a roll-shaped label paper according to an embodiment of the present invention. The roll-shaped label paper 1 (see FIG. 4B) before label printing includes a core material 10, an adhesive 11, a special label paper 12, and a release paper 13 (separator).

The core material 10 is a polyester film, specifically, a transparent PET # 12 film.

The pressure-sensitive adhesive 11 is an acrylic pressure-sensitive adhesive. An acrylic pressure-sensitive adhesive having a thickness of 20 μm is applied to both surfaces of the core material 10. That is, the pressure-sensitive adhesive layer is formed on both sides of the core material 10.

The label 16 is printed on printing paper, and for example, the printing portion 14 is formed on the special label paper 12. The special label paper 12 is a paper used for a label to be attached to a product, which is processed such as a pattern or a color among printing papers and has various kinds of thicknesses and materials. The printed portion 14 is a printed portion, that is, a portion processed with ink.

The special label paper 12 is attached onto the pressure-sensitive adhesive 11 applied to one side of the core material 10. Here, not all the special papers for labels of paper quality are in the form of rolls or continuous sheets in advance, and there are many special papers for labels that are in the form of sheets. The label special paper 12 in the present invention is obtained by butting the end faces of a plurality of sheet-fed special papers for labels. In this description, the portion where the end faces of the special label paper 12 are butted against each other is referred to as an end face portion 121.

The release paper 13 is attached onto the pressure-sensitive adhesive 11 applied to the other surface of the core material 10 (the surface opposite to the surface to which the special label paper 12 is attached).

As described above, the special label paper 12 and the release paper 13 are attached to both sides of the core material 10 by the adhesive 11. After that, label printing and partial cutting are performed. FIG. 2 is an explanatory diagram showing a structure after label printing and partial cutting are performed on the roll-shaped label paper according to the embodiment of the present invention. As shown in FIG. 2, the printing portion 14 is formed on the special label paper 12, and the label 16 is produced. Then, partial cutting is performed according to the size of the label 16. When the partial cutting is performed, the notch 141 is made from the special label paper 12 through the core material 10 to the front of the release paper 13.

FIG. 3 is an explanatory diagram showing a structure after removing the edge portion 15 (see FIG. 2) from the roll-shaped label paper according to the embodiment of the present invention in which label printing and partial cutting have been performed. As shown in FIG. 2, the edge portion 15 is a portion of a special label paper 12, a core material 10, and an adhesive 11 on which a printed portion 14 is not formed. As shown in FIG. 3, all the edge portions 15 are removed, and the core material 10 and the label 16 remain laminated on the release paper 13.

4A and 4B are explanatory views showing the appearance of the roll-shaped label paper according to the embodiment of the present invention, in which FIG. 4A is an appearance before the edge portion 15 is removed, and FIG. 4B is an appearance after the edge portion 15 is removed. be. As shown in FIGS. 4A and 4B, the core material 10 is rolled up in a roll shape in the direction of the arrow while the edge portion 15 is removed to form the roll-shaped label paper 1.

As described above, on the roll-shaped label paper 1, the laminate of the core material 10 and the label 16 attached on the release paper 13 remains. When the label 16 is actually attached to the product, the label 16 is peeled off from the release paper 13 together with the core material 10, and the label 16 is attached to the product by the adhesive 11 applied between the release paper 13 and the core material 10. Be worn.

The release paper 13 is coated with a release agent such as silicone so that it can be easily peeled off. On the other hand, no release agent is applied between the core material 10 and the special label paper 12. Therefore, when the label 16 is peeled off from the release paper 13, the core material 10 which is a polyester film is peeled off from the release paper 13 without peeling the special label paper 12 from the core material 10. Since the polyester film has tensile strength, it does not tear when it is peeled from the release paper 13. Therefore, it can be peeled off more cleanly than the roll-shaped label paper on which the special label paper 12 is directly attached to the release paper 13, and it is easy to use.

Further, because of such a laminated structure, the special label paper 12 is not directly attached to a product such as a liquor bottle, and the core material 10 is directly attached to the product. Since the core material 10 is made of hydrophobic polyester, it is possible to prevent the label from becoming damp, shrunk, or wrinkled by water droplets generated on the liquor bottle even if it is directly attached. Can be done.

[How to make roll-shaped label paper]
FIG. 5 is an explanatory diagram showing a process of attaching the special label paper 12 and the release paper 13 to the core material 10. Specifically, a step of applying the adhesive 11 to both sides of the core material 10, a step of sticking a plurality of sheet-fed special papers 12 for labels with their end faces facing each other, and a step of sticking a release paper 13. It is explanatory drawing which shows an example. In the example shown in FIG. 5, a plurality of sheet-fed special papers 12 for labels are arranged at the bottom with the end face portions 121 butted against each other. Further, the core material 10, the release paper 13, and the adhesive 11 are arranged on the special label paper 12 in the order shown in FIG. 5, and move in the direction of the arrow.

Therefore, the adhesive 11 is applied on the special label paper 12 by the pressure roller 17. Next, the core material 10 is pressure-bonded to the pressure-sensitive adhesive 11 applied to the special label paper 12 by the pressure roller 17. Then, the pressure-sensitive adhesive 11 is also applied onto the core material 10 by the pressure roller 17. Finally, the release paper 13 is pressure-bonded to the pressure-sensitive adhesive 11 applied to the core material 10 by the pressure roller 17.

By the step shown in FIG. 5, a structure (see FIG. 1) in which the special label paper 12 and the release paper 13 are attached to both sides of the core material 10 by the adhesive 11 is produced. In this way, since the plurality of sheet-fed special papers 12 for labels are crimped and fixed to the core material 10, it is necessary to bond the end face portions 121 with a single-sided adhesive tape or the like to join the special papers 12 for labels. do not have.

FIG. 6 is an explanatory diagram showing an example of a process in which the printing means and the cutting means perform label printing and partially cut the label 16 to the size of the label 16. In the example shown in FIG. 6, the label produced in the process shown in FIG. 5 is printed with a printing plate 21 as a printing means, and partially cut to the size of the label 16 with a blade mold 22 as a cutting means. ..

By the step shown in FIG. 6, the roll-shaped label paper 1 (see FIG. 4A) before the edge portion 15 is removed is produced. Then, the core material 10 is wound into a roll shape while the edge portion 15 is removed by the winding means, and the roll-shaped label paper 1 is produced.

The method for producing the roll-shaped label paper described above is merely an example, and can be appropriately changed without departing from the spirit of the invention.

[Label including end face]
FIG. 7 is an explanatory diagram showing a case where printing is performed on an end face portion of a sheet-fed special paper for a label. When printing is performed on the end face portion 121 as in the defective label 18 shown in FIG. 7, the print bleeds along the end face portion 121, or the end face portion 121 is a break in the paper, so that the label is used as a label. Useless.

Therefore, it is desirable to remove such a defective label 18 (label including the end face portion 121) from the roll-shaped label paper 1. For example, the detection means (not shown) detects the end face portion 121 before printing the label on the special label paper 12, and the portion determined to include the end face portion 121 in the print range is labeled by the printing plate 21. No printing will be done. Further, after printing the label on the special label paper 12, the end face portion 121 may be detected by the detecting means and the defective label 18 may be peeled off.

The detecting means can detect, for example, a break in the special label paper or a bleeding of printing by using a camera, and can determine that the end face portion 121 is included. Specifically, the vertical axis type inspection device "YST-200-Progress-4KC" (product name, manufactured by Yas Corporation Co., Ltd.) for small lots can be used to determine the portion including the end face portion 121. ..

INDUSTRIAL APPLICABILITY According to the present invention, roll-shaped label paper and roll-shaped label paper with improved convenience can be produced in which the label can be peeled off cleanly and the label attached to the product is prevented from shrinking or wrinkling due to water droplets. It is industrially useful because it is a method and can be used for various products to which labels are attached.
