Description

[Detailed Description of the Invention] Technical Field of the Invention The present invention provides a method for easily peeling off a flexible label base material with an identification mark from a release paper and easily attaching it to product packaging, etc. Regarding adhesive labels that can be used.

Technical background of the invention and its problems In general, adhesive labels consist of a label base material on which some kind of identification mark is printed on the long side, and a back side of the label base material that is used to attach this label base material to product packaging, etc. It consists of an adhesive layer formed on the adhesive layer and a release paper temporarily attached to the adhesive layer.

As a labeling device for automatically attaching the label base material of such an adhesive label to the packaging of a product, there is one shown in FIG. 6. In the labeling device 10 shown in FIG. 6, an adhesive label 11 consisting of a long release paper 2 to which a number of label base materials 1 having some kind of identification mark on the surface are temporarily pasted in the longitudinal direction is wound into a roll. A rolled body 3 is attached to an idling shaft 4. The release paper 2 of the adhesive label 11 taken out from the roll body 3 is continuously fed in the direction of the release paper folding portion 5 . In this release paper folding section 5, the release paper 2 is bent in the opposite direction at a steep angle, so that the label base material 1 temporarily pasted on the release paper 2 is peeled off from the release paper 2 and is directed toward the pasting roller 6. Distract to.

At the same time, product packages 7 and the like are conveyed one after another by the conveyor 8. When this package 7 is located below the sticking roller 6, the roller 6 moves downward and sticks the label base material 1 on the top of the package 7.

When the label base material 1 of the adhesive label 11 is continuously attached to the product packaging 7 etc. using such a labeling device 10, if the label base material 1 is sufficiently thick and relatively rigid, The label base material 1 conveniently protrudes in the direction of the roller 6 at the release paper folding portion 5.

By the way, in recent years, there are also ultra-thin adhesive labels in which the thickness of the label base material 1 is extremely thin. However, when attaching the label base material 1 of such an ultra-thin adhesive label to a product packaging 7 or the like using the labeling device 10 shown in FIG. 1 is not easily peeled off from the release paper 2 and bends together with the release paper 2, resulting in the packaging 7
There was a risk that it would not be possible to attach it properly. Therefore, in the past, it was necessary to use expensive equipment for ultra-thin adhesive labels.

In addition, when the label base material of such an ultra-thin adhesive label is manually attached to a product or product packaging, if the label base material is extremely thin and flexible, the label base material It is difficult to peel off the label from the release paper, and the process of attaching the label base material to the product packaging or the like is complicated.

Purpose of the invention The present invention was made in order to eliminate such inconveniences, and it is possible to easily peel off the flexible label base material with some kind of identification mark from the release paper, and to An object of the present invention is to provide an adhesive label whose base material can be reliably attached to product packaging, etc.

Summary of the invention In order to achieve the above object, the adhesive label according to the invention includes a release paper temporarily attached to the outer edge of a flexible label base material on an adhesive layer provided on the label base material. The label base material is characterized by forming a film layer that provides rigidity to the extent that the label base material does not bend together with the release paper when the label base material is peeled off from the label base material.

According to the adhesive label according to the present invention,
Although the label base material itself is thin and flexible, the film layer formed on its outer edge has appropriate rigidity, so when the release paper is peeled off from the label base material,
The label base material no longer follows the release paper and bends, and can be easily peeled off.
In particular, when a labeling device is used to attach a label base material in an adhesive label to a product packaging, etc., the label base material is easily peeled off from the release paper and is reliably affixed to the product packaging.

DETAILED DESCRIPTION OF THE INVENTION Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

In the adhesive label 20 according to an embodiment of the present invention shown in FIG. 1, an adhesive layer 22 is formed by applying an adhesive to a thickness of about 20 μm on the back side of a label base material 21 having a thin wall thickness of about 50 μm. It has been formed. Adhesive layer 2
Release paper 2 is temporarily attached to the surface of 2.

An identification mark is displayed on the surface of the label base material 21 by printing or the like. Moreover, a film layer 23 having a thickness of approximately 10 μm is continuously formed in the circumferential direction on the outer edge of the front surface of the label base material 21.

As the label base material 21, a flexible base material having a wall thickness of several μm to several tens of μm is used, which is made of a synthetic resin film such as vinyl chloride, polyethylene, polypropylene, or polyethylene terephthalate, or paper or metal foil. Further, as the adhesive forming the adhesive layer 22, an acrylic adhesive or a rubber adhesive is used.

As the film layer 23, a synthetic resin, paper, metal foil, or the like having a rigidity equal to or higher than that of the label base material 21 is used. In particular, when a synthetic resin is used as the film layer 23, the film layer 23 may be formed by applying a fluid synthetic resin to the label base material 21, or by pasting a film-like synthetic resin onto the label base material 21. The film layer 23 may be formed by doing so.

In the case of such an adhesive label 20, the label base material 21 itself is thin and easily deformed, but the film layer 23 formed on the outer edge of the label base material 21 This imparts appropriate rigidity. Therefore, even when such an adhesive label 20 is attached to a simple labeling device 10 as shown in FIG. 6 and the label base material is automatically attached to a product or product packaging 7, etc. At the curved portion 5, the label base material is prevented from being rolled up together with the release paper, is easily peeled off from the release paper, and can be conveniently and continuously stuck to the package 7 by the sticking roller 6. Furthermore, when the label base material 21 of such an adhesive label 20 is manually peeled off from the release paper 2 and manually affixed to a product or product packaging, the thin label base material 21 is formed on the outer edge thereof. Since the film layer 23 imparts appropriate rigidity to the label base material 21, these peeling and pasting operations can be easily performed.

Note that the present invention is not limited to the one embodiment described above, and can be modified in various ways.

For example, as shown in FIG. 2, an acrylic adhesive is applied to the back surface of a circular label base material 21a made of a polypropylene film with a thickness of 20 μm to form an adhesive layer 22a. A film layer 23a made of polyethylene terephthalate having a thickness of 25 μm and coated with an adhesive 25 may be attached to the outer edge of the front surface of the label base material 21a.

In addition, as shown in FIG. 3, epoxy resin is applied to the front and back surfaces of the outer edge of the label base material 21b made of brittle vinyl chloride film with a thickness of 25 μm.
The film layer 23b may be formed by applying the adhesive to a thickness of about 10 μm, and then the adhesive may be applied to the entire back surface of the label base material 21b to form the adhesive layer 22b.

Furthermore, as shown in FIG. 4, the film layer 23c
may be formed along the feeding direction 26 of the labeling device. This is because when attaching a label base material using a labeling device, the label base material is particularly required to have rigidity in the feeding direction.

Furthermore, as shown in FIG.
Alternatively, the adhesive layer 22d may be formed by applying the adhesive layer 22d, and the film layer 23d may be formed on the outer edge of the adhesive layer 22d. In the case of this embodiment, it is necessary to form an adhesive layer 25d also on the surface of the film layer 23d and to attach the release paper 2 to it.

Such adhesive labels 20a to 20d also have the same effect as the adhesive label 20 shown in FIG. 1.

Effects of the invention As explained above, according to the invention, a release paper temporarily attached to the adhesive layer provided on the label base material is attached to the outer edge of the flexible label base material. Since a film layer is formed that provides enough rigidity to prevent the label base material from bending along with the release paper when it is peeled off from the base material, the thin and flexible label base material can be peeled off from the release paper using a machine or hand. It has the excellent effect of being able to be easily peeled off from the label and also being able to reliably adhere this label base material to a product or product packaging.
