Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a roll-shaped label material, and its purpose is to be able to make a long label material and to be able to attach and peel it extremely easily, thereby improving work efficiency. The purpose of the present invention is to provide a roll-shaped label material with extremely high quality.

(Prior art) Conventionally, label materials for writing on the front surface or label materials that have been printed on the front surface are made by applying an adhesive to the entire back surface of a base material such as paper or plastic film and temporarily attaching it to release paper. Sheet-like label material is commonly used.

Furthermore, in order to automatically attach label materials by machines on factory lines, there are roll-shaped label materials in which a base material coated with an adhesive is wound with a release paper interposed therebetween and cut for sealing.

(Problems to be Solved by the Invention) In conventional sheet-shaped label materials, adhesive is applied to the entire back surface of the base material, so air is easily trapped and wrinkles occur, resulting in poor appearance after pasting. In addition to being bad, it was also difficult to peel off the label material, so it was extremely difficult to reattach the label material neatly.

After pasting the label material, the label material becomes unnecessary and when peeling the label material from the adherend, since the adhesive is applied to the entire back surface of the base material, it takes time to peel off and it may be necessary to forcefully peel it off. This may leave glue marks on the adherend or damage the adherend.

The label material was peeled off from the release paper (after that, the release paper was no longer needed and it had to be disposed of as garbage, which was time-consuming).

Furthermore, since the roll-shaped label material is wound with a release paper interposed therebetween, the winding diameter inevitably increases due to the thickness of the release paper, making it difficult to make it longer.

Therefore, the work of replacing the label material with a new one after running out of label material became frequent, and the line had to be stopped once for each replacement work, resulting in poor work efficiency.

In view of the above-mentioned circumstances, there has been a desire in the industry to create a roll-shaped label material that can be made into a long length, can be attached and peeled off very easily, and therefore has extremely high working efficiency.

(Means for Solving the Problems) The roll-shaped label material according to the present invention mainly includes an adhesive layer partially provided on one surface of a base material, and a release treatment layer provided on the other surface of the base material. A roll-shaped label material formed by winding a sheet-shaped label material, wherein when the sheet-shaped label material is wound, a release treatment layer is provided on at least the surface where the adhesive layer contacts the other surface of the base material. Since the roll-shaped label material is characterized in that it is provided with the following, all of the above-mentioned problems are solved.

(Structure of the invention) The configuration of this invention will be explained based on the drawings.

FIG. 1 is a cross-sectional view in the width direction of a sheet-shaped label material (2) constituting a roll-shaped label material pile according to the present invention, and in the figure (

In this invention, an adhesive layer (4) is partially disposed on one surface of the base material (3).

The position where the adhesive layer (4) is disposed is not particularly limited, and as shown in FIG. It may be in the form of a band in the longitudinal direction of the book, or it may be in the form of a band in the longitudinal direction of the base material (3) at the edges of both layers in the width direction of the base material (3) as shown in FIG. 2(B).
As shown in Figure (C), one strip may be formed in the longitudinal direction only at one peripheral edge in the width direction of the base material (3).

Further, it may be formed into a strip shape in the longitudinal direction approximately at the center of the base material (3) in the width direction. (Not shown) Furthermore, as shown in FIG. 2(D), the base material (3) may be shaped like a band extending in the width direction of the base material (3) at regular intervals in the longitudinal direction of the base material (3). The position, direction, number, etc. of the agent layer (4) are not particularly limited.

The material for the adhesive layer (4) is a rubbery polymer (natural rubber, polyvinyl butyralide, styrene, butadiene rubber, chlorinated rubber, polyvinyl ether, acrylic, etc.) and a tackifier (ester gum, phenolic resin, polyterpene resin, etc.). polystyrene resin, etc.) and a small amount of softener, filler,
Those containing stabilizers, crosslinking agents, etc. are preferably used.

In this invention, a release treatment layer (5) is provided on the other surface of the base material (3), and the sheet-like label material (2)
A release layer (5) is disposed at least on the surface where the adhesive layer (4) comes into contact with the other surface of the base material (3) when the adhesive layer (4) is wound.

That is, in the embodiment shown in FIG. 2(A), as shown in FIG. Strip-shaped release treatment layers (5) are provided at the edges of both layers in the longitudinal direction, respectively.

To provide the release layer (5), the sheet-like label material (2) is coated with solvent-based silicone or the like on the entire surface of the other surface of the base material (3) or by pattern treatment. In this case, the adhesive layer (4) may be applied to at least the surface of the base material (3) that contacts the other surface, and then dried and crosslinked.

When preparing a printed label material in this invention, as shown in FIG. Alternatively, when the sheet-like label material (2) is wound, a release layer (5) is provided at least on the surface where the adhesive layer (4) contacts the other surface of the base material (3). good.

In particular, when the label material requires writing, it is desirable not to provide the release layer (5) on the surface of the base material (3) that requires writing.

In particular, in the present invention, the sheet-like label material (1.2) is provided in a roll-like shape in which the broken portions (7) are provided at regular intervals in the longitudinal direction of the sheet-like label material (2) in the width direction. In the Ubel material pile, each label material can be easily cut by hand, further improving work efficiency when pasting label materials.

By winding the sheet-like label material part having the above-mentioned structure into a roll shape around a paper tube (8) as shown in FIG. In this case, it is sufficient to unwind this and cut the necessary number of label materials.

(Effects of the Invention) The roll-shaped label material according to the present invention is mainly a sheet-shaped label in which an adhesive layer is partially provided on one surface of a base material, and a release treatment layer is provided on the other surface of the base material. A roll-shaped label material formed by winding the sheet-shaped label material, wherein a release treatment layer is disposed at least on the surface where the adhesive layer contacts the other surface of the base material when the sheet-shaped label material is wound. Since it is a roll-shaped label material characterized by the following characteristics, it has the following effects.

It is possible to easily write on the side of the base material on which the release treatment layer is not provided.

Since an adhesive layer is partially provided on one side of the base material, the label material can be adhered neatly without air entrapment or wrinkles. When peeling off, it can be peeled off very easily, and there will be no adhesive residue left on the adherend or damage to the adherend.

Since no release paper is used, it is possible to make the label longer, which reduces the number of times the label material needs to be replaced with a new one after the label material runs out, especially on a factory line, thus improving work efficiency.

In particular, in the case of a roll-shaped label material in which broken parts are provided at regular intervals in the longitudinal direction of the sheet-shaped label material and extend across the width direction of the sheet-shaped label material, each label material has good manual tearability, and the label Work efficiency when pasting materials is further improved.
