Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention does not apply a pressure-sensitive adhesive to a label sheet having a pressure-sensitive adhesive applied to one side thereof, where perforations are formed for partitioning and separating the label sheet into unit labels. Therefore, the present invention relates to a label sheet characterized in that an adhesive does not adhere to the perforation blade of a perforation processing machine and the roll is not distorted when the label sheet is wound into a roll.

[0002]

2. Description of the Related Art Conventionally, labels have been attached to postcards, envelopes, forms and parcels, and products, and used for displaying information in various fields such as mail, delivery, distribution and retail. The configuration is such that necessary information such as personal information and a bar code is printed and printed at a predetermined position on the surface of the label sheet base material, while a pressure sensitive adhesive is applied to the back surface of the label sheet base material When the entire adhesive coated surface is covered with release paper that has been subjected to surface release treatment such as processing, or when the label sheet is in roll form, surface release treatment such as silicon processing directly on the label sheet base material surface Since the adhesive coated surface on the entire back surface of the base material is always in contact with this surface release treated surface, release paper is not required, and when labels are attached, individual labels are divided into unit labels. It is separated by perforations formed for separation and is attached to an object.

[0003]

However, when manufacturing such a label sheet, since the adhesive is usually applied to the entire back surface of the label sheet base material, the label sheet is divided into unit labels and separated. When forming the perforations for the perforation, the adhesive adheres to the perforation blade of the perforation processing machine, resulting in a decrease in the perforation processing accuracy and perforation unevenness. When separating the label, the label does not separate smoothly,
It may be damaged. In addition, the label sheet being fed may be stuck to the sewing machine blade to which the adhesive is attached, which may cause the feed failure of the label sheet, jamming, and the like, which may reduce the productivity of the label sheet. . Furthermore, during perforation processing, when the abutted perforation blade protrudes from the front surface side to the back surface side of the base material, there is an adhesive around the perforation of the perforation,
When the label sheet is wound up in a roll, the protrusion causes swelling, and this swelling causes distortion in the roll. This distortion not only impairs the appearance of the roll, but also deteriorates the feed stability of the label sheet when the roll is mounted on a device such as a printer or a label holder.

In view of the above problems, the present invention has a label structure in which the adhesive applied to the back surface of the sheet does not rise and project at the perforation forming portion, and the above problems are eliminated. The purpose of the present invention is to provide a label sheet that is easy to handle.

[0005]

To achieve this object, the label sheet of the present invention has perforations formed in a label sheet in which an adhesive is applied on one side and perforations are formed at predetermined locations. The part is to provide a label sheet which has not been coated with an adhesive, and a label sheet obtained by winding the label sheet into a roll.

[0006]

In the present invention, since the portion forming the perforations is the adhesive non-applied portion, the adhesion of the adhesive to the perforation blade of the perforation processing machine is eliminated, and the perforation processing accuracy is maintained. . Further, since there is no adhesive around the perforations of the perforations, the protrusions do not rise.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on the embodiments shown in FIGS. Here, FIG. 1 is a schematic perspective view of a label sheet of the present invention wound in a roll shape with an outer peripheral winding in a developed state, FIG. 2 is a partial explanatory view of FIG. 1, and FIG. FIG. 4 is a sectional view taken along line A-B in FIG.
It is a line sectional view.

A case where the label sheet 1 of the present invention is used as a delivery label will be described. As shown in FIG. 1, the surface of the label sheet base material 2 is provided with a silicon-based surface release treatment agent layer 4. Further, on the upper surface thereof, for each unit label 8, the product name, standard, quantity, etc. The information entry field K is printed. On the other hand, the pressure sensitive adhesive 5 is applied to the back surface 3 of the label sheet base material 2 so as to form the adhesive-uncoated portions 6 at equal intervals, and the pressure-sensitive adhesive 5 is applied to a substantially central portion of the adhesive-uncoated portion 6. Has perforations 7 for partitioning / separating the label sheet 1 into unit labels 8. With this adhesive-uncoated portion 6, the perforated blade that is abutted during perforation processing is
When the sheet base material 2 projects from the front surface to the back surface 3, the base material 2
There is no adhesive 5 around the perforations of
Further, when the unit label 8 is attached, the uncoated portion 6 also serves as a margin for picking the label. Here, in the present invention, the release agent is, for example, a silicon-based water-soluble release agent such as water-soluble silicone oil, silicone oil emulsion, or silicone rubber emulsion, or a water-repellent agent containing Warner-type chromium complex salt as a main component. The main examples are non-silicone water-soluble release agents such as polyethyleneimine water-soluble polymers, but release inks containing release substances such as silicone and wax may also be used.
The surface release treatment agent layer does not necessarily have to be formed on the entire surface of the base material as in the present embodiment, and is partially formed so as to face the partial adhesive coating pattern. May be. A release agent-impregnating layer is usually provided between the label sheet base material and the release agent. Therefore, the surface release treatment layer 4 in the invention usually includes the release-agent impregnating layer. However, it is also applicable when this is not provided. On the other hand, as the pressure-sensitive adhesive 5, an ordinary pressure-sensitive adhesive or a pressure-sensitive adhesive that can be peeled off and re-adhered is used. The combination of the above-mentioned release agent and pressure-sensitive adhesive, or the coating amount thereof is appropriately selected depending on the use of the label, the material of the label base material, the environment in which the label is used, and the like. Therefore, the surface peeling treatment layer may not be provided depending on the adhesive strength.

Further, in this embodiment, the adhesive-uncoated portion 6 is provided along both longitudinal sides of the label sheet 1, which is a wide label sheet which is processed beforehand. In the case where a plurality of label sheets 1 are manufactured by slitting into a predetermined width, the adhesive 5 does not adhere to the slit blade during slit processing, and therefore, the same action as that of the sewing machine blade is obtained. In addition, it is possible to prevent the trouble that the adhesive 5 sticks out from both ends of the label sheet 1 during long-term stock. In this embodiment, the delivery label is given, but in other cases, the delivery label,
It can also be applied to inventory labels and various journal labels.

EFFECTS OF THE INVENTION According to the present invention, the adhesive does not adhere to the perforation blade of the perforation processing machine, the perforation processing accuracy is maintained, and the labels can be smoothly separated when separating the individual labels. When the label sheet is wound into a roll, the eye protrusion does not swell up due to the adhesive, and the roll can be neatly wound without distortion, and the roll is mounted on a printer, label holder, or other device. However, the feed stability of the label sheet is improved. Furthermore, when separated into unit labels, the adhesive-uncoated part serves as a margin for picking up the label, making it difficult for the adhesive to touch the finger, so label handling, or alignment when attaching the label, etc. Further, it is easy, and even when the attached label is peeled off, it can be easily peeled off from the picking margin.
