Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a label printing paper used for printing addresses of direct mail, etc., and particularly to a label printing paper suitable for printing using a dot impact printer.

[Background of the invention]

In conventional label printing paper, the release base paper is exposed between the upper paper label and the release base paper. If there is no exposure between the upper paper labels, the squares of the upper label paper are at right angles, and each upper label paper is independent, so it is easy to peel, but it is easy to remove with an impact printer etc. No consideration was given to equipment failure due to peeling during printing. That is, conventional label printing paper is constructed by coating a release base paper 2a with a release agent 4a and an adhesive 3a, and then pasting a top paper label 1a called high-quality paper on top of the release base paper 2a, as shown in FIGS. 4 and 5. As shown in FIG. 5, since the unnecessary portion of the upper paper label 1a is removed, there is a difference in level between the upper paper label 1a and the release base paper 2a. Therefore, when the label printing paper 10 is bent, the upper paper label 1a is easily separated from the release base paper 2a.

As shown in FIG. 6, when the label printing paper 10 is attached to the printer 30 equipped with the tractor feeder 20, the label is attached to the platen (not shown) which is the paper winding mechanism inside the printer 30. When the printing paper 10 is placed and fed or ejected, the upper paper label 1 is
a easily peels off from the release base paper 2a and adheres everywhere inside the printer 30. This resulted in printer 300 malfunctioning, which required the assistance of a knowledgeable technician to repair. Furthermore, label printing paper 1
If the paper setting position in the printer 30 is misaligned with the print command position on the host side (for example, a word processor), the print head (not shown) inside the printer 30 may Various printer failures have occurred frequently, such as printing on the edge of the paper 2a, which may also cause breakage of the wire bin inside the head.

[Object of the Invention] The object of the present invention is that when printing on label paper using an impact printer, especially a platen-wrapping type printer, the label paper peels off during printing, and after printing is completed, the label paper peels off. To provide a label printing paper which allows the paper to be easily peeled off from a release base paper.

[Summary of the invention]

Conventional label paper, in which a top paper is attached to a release base paper, is manufactured with emphasis on ease of peeling, so the edges of the label paper tend to turn over when handled when installed in a printer or the like. As a result, the parts that turned up while the printer was feeding the paper adhered to the inside of the device, causing many strips of label paper to peel off. On the printer side, this not only hinders the printing function due to the attached label paper, but also causes unevenness on the paper side due to the peeling of the label paper, resulting in damage to the wire bin of the printer's print head, etc.
This was the cause of the next failure.

The present invention maintains the ease of peeling that is a characteristic of label paper, but in order to make it difficult to peel off during handling, during installation in a printer, and before and after that, the present invention does not create a step between the top paper and the release base paper, and The above object is achieved by chamfering at least two corners of the upper paper label and providing a connecting portion between the upper paper sheets.

[Detailed embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. In the label printing paper 10 of this embodiment, a release agent 4 and an adhesive 3 are applied on a release base paper 2, and then a top paper label 1, which is called high-quality paper, is pasted on the entire surface of the release base paper 2. After that, a cut 8 is made in the upper paper label 1 in a desired shape using a knife or the like, so that the upper paper label 1 can be easily peeled off.

This label printing paper 10 has an unnecessary part 5 of the upper paper label 1.
1 paper label 1 and release base paper 2 by leaving on release base paper 2
Eliminate the step between the upper and lower paper labels 1 and connect the
By providing this, it is possible to prevent the upper paper label 1 from peeling off when the label printing paper 10 is bent in the paper feeding direction. Furthermore, by providing curved chamfers at each corner of the upper paper label 1, it is possible to protect the edges of the upper paper label 1 from turning up, which may occur during handling or installation in the printer 30. One method to examine this effect is the 180° beer test. According to this test, it was confirmed that the peel strength was improved by about 10 times compared to the conventional one. But general 1! Considering the case of i1, if the peel strength is improved, a contradictory problem arises in that the upper paper label 1 becomes difficult to remove. As a result of experiments, it was found that this was caused by the spacing and number of the upper and lower connecting parts 60 of the upper paper label 1, as well as the width of the connecting parts 60.

In this embodiment, the dimensional relationship of the connecting portions 6, that is, dl, d, d, with respect to the width do of the upper paper label 10 is approximately do/3.
If the width of the upper paper label 10 is divided into two approximately three equal parts, and the width of the connecting part 60 is set to 0.5 to 1 m, it is possible to create a label printing paper 10 that is easy to remove while maintaining peel strength. It could be confirmed.

Of course, the thickness of the upper paper label 1 and the release base paper 2 are also important factors. Regarding this, the thickness of the two is approximately the same, and the thickness of each is about 45 g/m in terms of weight, so that the label printing paper 10 is soft and the overall thickness is 130 g/m in terms of weight. "It's in good condition. This is the same thickness as the paper used in commercially available electrophotographic copying machines, and there is no problem with the thickness for the printer 30. Although this embodiment has been described using continuous label printing paper, it goes without saying that the same effect can be obtained with cut paper.

〔Effect of the invention〕

As detailed above, according to the present invention, during printing on label printing paper with an impact printer etc., it has excellent mechanical strength.
When removing only the upper paper label after printing is completed, it can be easily peeled off, so that it is possible to provide a label printing paper with high operability and reliability.
