Abstract

PURPOSE:To enable tight winding with an emulsive adhesive and to prevent the outward appearance from becoming shabby even in the case of an environmental change by providing a mat varnish layer on the surface of at least the superimposing adhesion part of the label. CONSTITUTION:The label 1 has a pattern, characters, etc., printed 12 on its surface and the mat varnish layer 14 is provided on the surface of the print 12 on the surface of the superimposing adhesion part 13. Mat varnish forming the mat varnish layer 14 consists preferably and principally of nitrified-cotton medium. No special adhesive is therefore used and the label can tightly be wound by using the emulsive adhesive 13 without providing a part (margin) where no print 12 is provided on the surface of the superimposing adhesion part 13; even if the label wound around a container expands or shrinks owing to the environmental change, its outward appearance does not become shabby.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper label that is wrapped around a container such as a glass bottle or a plastic bottle.

0002

2. Description of the Related Art This type of label is, for example, one that is wrapped around the body of a glass bottle of instant coffee or the like. In order to wrap such a label around a bottle, if the polymerized adhesive part 13 is attached using a special adhesive, it can be bonded without providing an unprinted part on the surface of the polymerized adhesive part 13, but normally As shown in FIG. 3, a non-printed part is provided on the surface of the polymerized adhesive part 13, and this is used as a glue margin 15 to be wrapped around the body as shown in FIG. An adhesive is applied to the glue margin 15 of 13, and the front and back sides are overlapped and bonded.

[0003] In addition, this type of label is usually wrapped tightly around the body of the bottle, and is currently adhered using an emulsion adhesive to reduce cost. .

However, since such a label is made of paper, it expands and contracts with changes in the outside air after being wrapped, elongating when the humidity is high and drying and shrinking when the humidity is low.

[0005] When the label wrapped around the bottle shrinks, the glue allowance 15 becomes exposed and becomes visible as shown in Figure 5, and when it stretches, as shown in Figure 6. As shown, a phenomenon occurs in which the ends of the polymerized adhesive portion 13 are rolled up, and in any case, there is a problem in that the appearance becomes unsightly.

[0006]

OBJECTS OF THE INVENTION The present invention has been made to solve these problems, and it is possible to solve the above problems without using a special adhesive as in the past. It is possible to wrap firmly with emulsion adhesive without having to provide any unprinted parts, and
It is an object of the present invention to provide a label whose appearance does not become unsightly even when the outside air changes.

[0007]

[Means for Solving the Problems] In order to solve the above problems, the present invention provides a polymerization method in which printing is applied to the surface, and the front and back sides are overlapped at both left and right ends and bonded with an emulsion adhesive. A paper label to be wrapped around the body of a container having an adhesive part is characterized in that a matte varnish layer is provided on at least the surface of the polymerized adhesive part. Further, it is preferable that the matte varnish has a composition mainly composed of a nitrocotton-based medium.

[0008]

[Function] According to the present invention, by providing a matte varnish layer on at least the surface of the polymer adhesive part of the label, the area where printing is not performed (glue margin) on the surface of the polymer adhesive part which will be the adhesive margin ) can be firmly bonded using an emulsion adhesive. Therefore, if the label shrinks, the adhesive portion will be exposed and become visible, or if the label stretches, the edges of the overlapping part will be rolled up, but the appearance will not change. There is no need to worry about the situation becoming unsightly.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 shows an embodiment of the present invention, and FIG. 2 shows a state in which the label 1 of FIG. 1 is wrapped around the body of a glass bottle 2. As shown in FIG. This label 1 has a pattern, characters, etc. printed 12 on the surface of paper 11, and the surface of the polymerized adhesive part 13 has
A matte varnish layer 14 is provided on the printed surface 13.

[0010] The matte varnish forming the matte varnish layer 14 is preferably applied with a composition mainly composed of a nitrified cotton-based medium, for example, UPPS medium (manufactured by Toyo Ink Manufacturing Co., Ltd.) as a main component, A structure using NC102 (manufactured by Toyo Ink Manufacturing Co., Ltd.) as a solvent can be used.

Further, as shown in FIG. 2, the label 1 is wrapped around the body of the glass bottle 2 by applying an emulsion adhesive 3 to the surface of the polymer adhesive 13.

[0012] Here, in the above-mentioned embodiment, the structure in which the matte varnish layer 14 was provided on the polymerized adhesive part 13 was shown, but as long as it does not affect the printed pattern on the surface of the label, the structure in which the matte varnish layer 14 is provided on the entire surface may also be used. good.

Next, an experiment was conducted to confirm the adhesive strength of the label of the present invention, and the method and results are shown below.

(Experimental Method and Results) (Sample 1) Polyamide-based ink M was applied to the surface of single-sided art-treated paper with a basis weight of 64.5 g/m2 using a gravure printing method.
A label of the present invention was obtained by printing FG (manufactured by Toyo Ink Manufacturing Co., Ltd.) and then applying matte varnish containing UPPS medium as a main component to the surface using a gravure plate with a plate depth of 32 to 34 μm. An emulsion adhesive was applied to the surface of this polymerized adhesive portion, and it was wrapped around a glass bottle. (Sample 2) A label printed on the surface and without matte varnish treatment on the polymerized adhesive portion was wrapped around a glass bottle in the same manner as in (Sample 1). (Sample 3) Label without printing or matte varnish treatment (
It was wrapped around a glass bottle in the same manner as sample 1). (Measurement method) Peel strength was measured by cutting each sample to a width of 15 mm in a direction perpendicular to the polymerized adhesive portion, and measuring the peel strength using a tensile tester at a descending speed of 200 mm/min.

(Measurement results) (Sample 1) 194 g/15 mm width (Sample 2) 54 g/15 mm width (Sample 3) 142 g/15 mm width From the above results, the label of the present invention has excellent adhesive strength. can be understood.

[0016]

[Effects of the Invention] Since the present invention has the above-described structure, unlike the conventional method, there is no need to use a special adhesive, and the surface of the polymerized adhesive part is free from printing (glue allowance). ) can be firmly wrapped with an emulsion-based adhesive, and has the excellent effect of not causing an unsightly appearance even if the label wrapped around the container expands or contracts due to changes in the outside air. It is something that plays.
