Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-sided pressure-sensitive adhesive label holding tape for holding an double-sided pressure-sensitive adhesive label used for connecting articles to each other until use.

[0002]

2. Description of the Related Art A double-sided pressure-sensitive adhesive tape that has been conventionally used is constructed by sticking a continuous double-sided pressure-sensitive adhesive sheet on a continuous release sheet. This double-sided pressure-sensitive adhesive tape is generally wound into a wound shape. When using this roll-shaped double-sided pressure-sensitive adhesive tape, the release sheet is peeled off from the roll at a desired length, cut, and attached to the article as it is. Next, the release sheet is peeled off, and the other article for connection is stuck on and connected.

[0003]

In the conventional wound double-sided pressure-sensitive adhesive tape, since the double-sided pressure-sensitive adhesive sheet portion is very flexible after the release sheet is peeled off, only the double-sided pressure-sensitive adhesive sheet portion is handled to be an article. Sticking is difficult. In addition, when the release sheet is peeled off, the double-sided pressure-sensitive adhesive tape and the release sheet are in very good contact with each other, so that there is a problem that it takes time and effort to remove them.

The present invention solves the above problems and provides a double-sided pressure-sensitive adhesive label holding tape which can be attached only by the double-sided pressure-sensitive adhesive sheet portion after peeling off the release sheet, and which does not take much time to peel off the release sheet. The purpose is to supply.

[0005]

A double-sided pressure-sensitive adhesive label holding tape according to the present invention comprises a continuous first release sheet, a double-sided pressure-sensitive adhesive label sheet adhered onto the first release sheet, A double-sided pressure-sensitive adhesive label holding tape comprising a continuous second release sheet attached from above the double-sided pressure-sensitive adhesive label sheet, wherein the double-sided pressure-sensitive adhesive label sheet has a Gurley method (J. TAPPI paper pulp test method NO. 40-83), and a Gurley stiffness of 250 mgf or more.

The double-sided pressure-sensitive adhesive label sheet may be divided into pieces along the longitudinal direction and attached as a plurality of double-sided pressure-sensitive adhesive labels.

[0007]

The double-sided pressure-sensitive adhesive label holding tape according to the present invention is supported by being sandwiched between the continuous first release sheet and the continuous second release sheet. It has such a rigidity as to have a Gurley stiffness of 250 mgf or more by the Gurley method (defined in J. TAPPI paper pulp test method No. 40-83).

EXAMPLE A double-sided pressure-sensitive adhesive label holding tape according to the present invention will be described with reference to FIG. 1 showing an example thereof. FIG. 1 is a perspective view showing the structure of one embodiment of the double-sided adhesive label holding tape of the present invention. Double-sided adhesive label in section 3,
.. are arranged side by side on the continuous first release sheet 1. Furthermore, double-sided adhesive labels 3, 3, ...
The continuous second release sheet 2 is overlaid on the above.
The thickness of these continuous release sheets 1 and 2 is 0.07 mm
The transparent PET film of is used. The double-sided pressure-sensitive adhesive label holding tape 4 thus configured is wound around the paper tube 5 to form a double-sided pressure-sensitive adhesive label holding tape 6 in consideration of portability and storability.

Next, the structure of the double-sided adhesive label 3 will be described below. FIG. 2 is a sectional view showing one structural example of the double-sided adhesive label 3. This double-sided pressure-sensitive adhesive label 3 is formed by attaching two sheets of glassine tracing paper having a thickness of 0.08 mm, a length of 70 mm and a width of 20 mm as a support 7 with a water-soluble double-sided tape 8 having a thickness of 0.15 mm, and further outside thereof. The same water-soluble double-sided tape 8 is attached to the above.

In the example of the double-sided adhesive label holding tape shown in FIG. 1, the double-sided adhesive labels 3, 3, ... Are arranged side by side at regular intervals. On the other hand, the double-sided pressure-sensitive adhesive labels 3, 3, ... May be arranged side by side with their ends in contact with each other, or a single continuous double-sided pressure-sensitive adhesive label sheet may be arranged. The double-sided adhesive label 3 is composed of two layers of the support 7 and three sheets of the water-soluble double-sided tape 8 and thus has a certain degree of rigidity. Therefore, even when the release sheets 1 and 2 are not provided, it is possible to easily handle only the double-sided adhesive label portion and attach it to the article. Of course, the three-layer structure in which one support is simply sandwiched between two double-sided tapes may be adopted instead of the five-layer structure. In this case, in order to give the double-sided adhesive label a certain degree of rigidity, it is necessary to use a rigid material such as plastic as the support. If the double-sided pressure-sensitive adhesive label bends when the double-sided pressure-sensitive adhesive label is supported by one end, it becomes unfavorable for the subsequent handling of the double-sided pressure-sensitive adhesive label.
That is, when the label has a habit of being bent or when the label is bent, it becomes difficult to grip the label even when it is gripped with fingers. In order to prevent such unwanted bending, it is necessary that the double-sided adhesive label has a certain degree of elasticity. For that purpose, the double-sided pressure-sensitive adhesive label preferably has a support.

As a result of repeating various trials, it was found that the double-sided pressure-sensitive adhesive label had a certain degree of waist strength, which was determined by the Gurley method (J. TAPPI paper pulp test method N).
O. 40-83), it was found that the Gurley stiffness of 250 mgf or more was sufficient. In this test, the place where the contact member of the tester contacts the double-sided adhesive label was masked with a thin paper or film. Specifically, the waist strength is such a strength that the double-sided pressure-sensitive adhesive label does not bend so much when it is supported by holding the end portion.

Further, since it has a certain degree of rigidity as described above, it does not follow the deformation of the release sheet and closely adhere to it, unlike the pressure-sensitive adhesive sheet portion of the conventional double-sided pressure-sensitive adhesive tape. Since the gap between the double-sided adhesive label 3 and the release sheet 1 or 2 can be easily made by bending or bending the holding tape 4, the release sheet can be easily peeled from the double-sided adhesive label holding tape 4. be able to.

Also, by arranging the double-sided adhesive labels with a gap therebetween, if the first and second release sheets are torn and cut at that portion, the double-sided adhesive label 3 does not exist at that portion, so the peeling is performed. You can also easily peel it off by pinching the edges of the sheet with your fingers. As described above, the use of glassineized tracing paper and the water-soluble double-sided tape 8 as the support 7 of the double-sided adhesive label has the following advantages. When this double-sided adhesive label 3 is used when connecting the paper and the new spool at the time of changing the winding frame in the winding machine, after the use, the portion of the paper is attached to the paper when it is recycled as a damaged paper. This is an advantage that the attached double-sided adhesive label does not interfere with the recycling process.

In the above-mentioned examples, glassine tracing paper was used as the support for the double-sided adhesive label. In addition to this, as a support that can be reprocessed, general paper can be mentioned. When general paper is used as the support,
Depending on the method of use, delamination may occur in the support due to the large tensile force that acts after connecting the articles. In particular, a large pulling force is exerted when the web and the new spool are connected and wound at the time of changing the winding frame in the winding machine, so that it is necessary to select a support body which does not cause such delamination. .

A non-woven fabric is one that does not easily cause delamination and does not hinder the regeneration process. If such a large pulling force works, there is essentially no delamination, and it is preferable to use a polymer film of vinyl chloride, polyethylene, or the like, if there is no problem in the recycling process.

The double-sided pressure-sensitive adhesive label sheet held by the double-sided pressure-sensitive adhesive label holding tape of the present invention is manufactured by the Gurley method (J. TA).
PPI paper pulp test method NO. 40-83) 2 in
Since it has a rigidity to the extent that it has a Gurley stiffness of 50 mgf or more, it is possible to attach only the double-sided adhesive label sheet portion after peeling the release sheet.
Further, it is a double-sided pressure-sensitive adhesive label holding tape which has rigidity and does not take much time to peel off the release sheet.
