Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a label in which a transparent laminate film is provided extending beyond the outline of the label.
In the label manufacturing process, a punching process for the laminate film is performed after the label printing part is punched out, so that the punching outline of the laminate film is made larger than that of the label printing part.

Conventionally, labels with pressure-sensitive adhesive on the back side have generally had a transparent or translucent laminating film polymerized on the top side of the printed label, but the outline of the label and its top side have been polymerized. The transparent laminate film had the same outline.

However, in this conventional general label, the end face of the punched outline is the sum of the thickness of the label paper and the thickness of the transparent laminate film provided on the surface thereof. When this label is affixed to various objects, it can be peeled off relatively easily by applying a fingernail to the end surface two or three times, although this is a microscopic observation.

This is because the end surface of the laminated label and film is perpendicular to the surface of the object. This phenomenon is particularly noticeable when the label is wrapped around and attached to the surface of a shaft-shaped object having a relatively small diameter. The present invention provides a label of this type that is extremely difficult to peel off by reducing the thickness of the end face of the label to the thickness of only the laminate film. explain.

FIG. 1 is a perspective view of a label according to the present invention, showing a state in which a large number of labels are lined up on the upper surface of a release paper 1, and a cross-sectional state is shown in FIG. 2 as shown in FIG. This is a state in which a transparent laminate film 3 is provided.

In the label of the present invention, the shape and position of the protruding part of the laminate film provided on the surface of the label paper can be set as appropriate. For example, as shown in FIG. It is also possible to provide protruding portions 4 on both sides of the short side as shown in FIG.
4 can also be provided.

In particular, labels with a transparent laminated film protruding around the entire circumference of the label as shown in Figures 1 and 2 can prevent water droplets from entering from the surrounding area, so it is recommended to use normal hygroscopic paper as the material for the label paper. However, the same effect as plastic paper can be obtained, and the label itself is also the most difficult to remove.

Furthermore, the label shown in FIG. 3 has the advantage that when it is wrapped around a shaft-like object 5 as shown in FIG. It has the advantage of being strong and difficult to peel off. Next, a method for manufacturing a label according to the present invention will be explained based on FIG. 6.

In the figure, [phase] is an original fabric shaft, and a plain label paper 2 having a pressure-sensitive adhesive on the back surface is wound in a polymerized state together with a release paper 1.

In the present invention, one end of the label paper 2 is pulled out, a desired label is printed on the top surface of the label paper using a printing machine ◎, and then only the label paper 2 is punched out into a predetermined label shape using a punching machine @. Leaving the printing part 5, the remaining (gas) ◎ is rolled up on the axis O to perform so-called gas raising. Next, a transparent or translucent laminating film 3 having a pressure-sensitive adhesive on the release surface is continuously pasted on the entire surface of the release paper 1 on which the label printing part remains, using a pressure roller O, and then a punching machine 5 The film 3 is adjusted so that a desired area of the laminated film protrudes from the outline of the label printing section 6 at a predetermined location.
The remaining final label 7 is punched out, leaving the final label 7 on the release paper 1, and the punching gas of the film is rolled up onto the shaft to raise the gas. phase]
Wind it up. In addition, in the above manufacturing method, during the second punching with the punching machine @, only the laminate film 3 pasted on the top surface of the label printing part 5 is made to closely match the outline of the other label printing parts, excluding the protruding part. It is actually extremely difficult to punch out the material.

For this reason, when punching out the label printing part using the first punching machine, the outline of the laminate film except for the protruding part 4 is punched out to be slightly larger than the outline of the final label 7. When punching out with a punching machine after pasting, the laminate film 3 and the label printing part 6 are cut out.
If the larger portion is simultaneously punched out to form the final label shape, a label with uniform punched end surfaces can be obtained. In the above process, the laminating film 3 is polymerized and integrated with the release paper 8 in advance, and is unwound from the wound original film O to form the release paper 8.
The release paper is wound up around a shaft 9, and only the film 3 is pasted onto the upper surface of the product part of the label. This method is conventionally used.

Incidentally, the gas ◎ produced by the above-mentioned first punching may be rolled up on the shaft 9 together with the above-mentioned release paper 8. Although the present invention is extremely simple in structure as described above, it has great utility value, and can be easily manufactured by adding one punching machine of a different type. Therefore, a label with high utility value can be obtained without significantly increasing the cost compared to conventional products.

Claims (1)

[Claims] 1. Unwind label paper with pressure-sensitive adhesive that is integrally polymerized with release paper from the shaft, print multiple labels continuously on the surface of the label paper, then punch out only the label paper into a predetermined shape, and separate each label paper into a predetermined shape. Leave the label printing area and remove the residue, then successively laminate a transparent or translucent laminating film on the top of each label printing area, and then apply a desired area of laminate film to a predetermined area from the outline of the label printing area. Production of a label characterized in that the final label is punched out into a final label shape so that the label sticks out, the residue is scraped off, and the final label covered with a laminate film is continuously left on the release paper and then wound around a shaft.
