Description

    The present invention relates to a self-adhesive label and a method for deactivating the adhesive, and in particular, the self-adhesive has a characteristic that it adheres to each other but is difficult to adhere to other members such as general paper materials and film materials. The present invention relates to a label and a method for deactivating the adhesive.

Conventional self-adhesive labels have a label base material and a self-adhesive adhesive layer provided on the back side of the label base material.
The label substrate is composed of kraft paper, high-quality paper, any other paper material or synthetic resin material having a relatively rough surface.
Self-adhesive adhesive layer self-adhesive adhesives adhere firmly to each other when the pressure-sensitive surfaces of the self-adhesive adhesive layers are brought into contact with each other, but if you try to force them apart, the self-adhesive adhesive layer itself is self-adhesive label On the other hand, it has a characteristic that it is difficult to adhere even if the self-adhesive adhesive layer is pressed against another member.
Therefore, a label having a general pressure-sensitive adhesive layer requires a release paper (mounting paper) for its backing, but does not require the release paper itself, which saves resources and reduces the burden on the environment. There is an advantage of less.

However, since the self-adhesive label has no release paper and the surfaces of the self-adhesive adhesive layer are easy to adhere to each other, care must be taken in handling them, and part of the self-adhesive adhesive layer depends on the use mode. It may be necessary to lose its adhesion, i.e. to deactivate it.
Conventionally, an inactivation method has been employed in which UV-curable varnish, medium, or the like is applied and printed on the self-adhesive adhesive layer in various printing patterns.
Therefore, this deactivation method requires a large printing press and other equipment, and the pitch and layout are limited at the time of pattern coating, or it is difficult to produce in a small lot, so it is expensive. There are various problems.

The adhesive deactivation layer 20 can be transferred and printed on the adhesive layer 3.

Therefore, by loading the self-adhesive label continuous body 1 into the double-sided printer 25, necessary variable information can be printed on the front and back surfaces of the self-adhesive label continuous body 1, respectively.
For example, FIG. 10 is a plan view showing the front side of the self-adhesive label 7A, which will be described taking as an example the case where the continuous self-adhesive label 1A (self-adhesive label 7A) is created as an envelope, and FIG. FIG.
On the front side of the self-adhesive label 7A, a fold line 28 located at the center of the self-adhesive label 7A is defined as a boundary, and a first region 29 and a second region 30 are defined on the left and right sides thereof.
In the first area 29, in the first printing section 26 of the double-sided printer 25, the address name 31 of the sender of the envelope is provided as the first variable information in the thermal color former layer 4 of the self-adhering label 7A. In addition to printing, the address and name 32 of the recipient are printed in the second area 30.

Furthermore, a third region 33 and a fourth region 34 are defined on the left and right sides of the self-adhesive adhesive layer 3 on the back surface side of the self-adhesive label 7A with the fold line 28 as a boundary.
In the third area 33, an adhesive deactivation layer 35 with a predetermined printing pattern (for example, a rectangular pattern) is laminated as second variable information in the second printing unit 27 of the double-sided printing printer 25. At the same time as printing, an adhesive deactivation layer 36 as predetermined variable information (for example, contents such as “admiration...”) Is laminated and printed in the fourth area 34.
However, by setting the range occupied by the adhesive deactivation layer 35 to be larger than the range 36A occupied by the adhesive deactivation layer 36, the adhesive deactivation layer 35 can be surely bonded to the adhesive deactivation layer 36. It is desirable to be able to cover.

    If the self-adhesive label 7A is folded in half at the fold line 28 after such lamination printing, the adhesive deactivation layer 35 faces the adhesive deactivation layer 36 on the back side of the self-adhesion label 7A. Therefore, since the self-adhesive adhesive layer 3 in the peripheral portion other than the adhesive deactivation layer 36 and the adhesive deactivation layer 35 is adhered to each other without sticking to each other, the adhesive deactivation layer The content by 36 can be completed as an envelope 37 while protecting.

FIG. 12 is a plan view of the completed envelope 37, and the recipient who has received the envelope 37 peels off the third region 33 from the fourth region 34 in the self-adhesive adhesive layer 3 at the periphery. Alternatively, by cutting with scissors or the like, the contents (variable information) of the adhesive deactivation layer 36 in the fourth region 34 can be seen.
However, in this peeling operation, since the portion of the self-adhesive adhesive layer 3 at the peripheral edge is peeled off from the label base material 2, it is clear that it has been opened.
Therefore, the envelope 37 can practically function as a confidential, and such an envelope 37 can be easily created by the double-sided printer 25 (FIG. 9) and flexibly according to the situation. .

    Of course, the adhesive deactivation layer 35 and the adhesive deactivation layer 36 are formed by the thermal transfer printer 10 (FIG. 3), and the sender's address name 31 and the recipient's address name are formed by the thermal printer 24 (FIG. 8). The envelope 37 can be created by dividing the printing operation into two stages so that 32 is printed.

    Thus, according to the self-adhesive label continuous body 1A (self-adhesive label 7A) of the present invention, the self-adhesive adhesive is inactivated with an arbitrary print pattern (for example, the print pattern 21 (FIG. 5)) as necessary. In addition to the display of the fixed information 9 (FIG. 1), the variable information 22 and 23 (FIGS. 6 and 7) and the adhesive deactivation layer 35 and the adhesive The activation layer 36 (FIG. 11) can be displayed, and the range of use of the illustrated envelope 37 (FIG. 12) can be expanded to various information transmission, advertisement display, management display, and the like.

    Furthermore, unlike conventional pressure sensitive labels, it is not necessary to use release paper (mounting paper), which saves resources and reduces the burden on the environment.
