Description

  The present invention relates to a conveyance label capable of covering and holding a conveyance component on a conveyance sheet, a conveyance sheet having the conveyance label adhered thereto, and a method for manufacturing the conveyance label.

  Conventionally, when an article such as an IC card is conveyed, it has been studied to cover an article such as an IC card placed on the surface of a conveyance sheet with a conveyance label. In the case of an IC card, for example, an IC card is placed on the surface of a transport sheet, the surface of the IC card is covered with a transport label, and the adhesive layer on the periphery of the transport label is attached to the surface of the transport sheet. It has been studied to transport the IC card while the IC card is held on the transport sheet.

As a label that could be used for this transport label, an adhesive layer was laminated on the surface of a substrate having a gripping part at the end, and was printed only on the surface of the adhesive layer laminated on the gripping part. A sealing label in which a non-tackifying layer is laminated is known (see Patent Document 1).
However, since the surface of the pressure-sensitive adhesive layer other than the gripping portion is in a state where the adhesiveness is maintained, this sealing label is transported to the IC card even if the transport label is peeled off after the IC card is coated and stuck. There was a problem that it was difficult to peel off smoothly because the pressure-sensitive adhesive layer of the label was firmly fixed.

  As a pressure-sensitive adhesive label that can be improved, pattern printing is performed on the exposed surface of the pressure-sensitive adhesive layer provided on the back surface of the base material with printing ink, and the exposed and concealed portions of the pressure-sensitive adhesive layer surface depending on the state of the pattern The adhesive structure of the adhesive layer is adjusted to weaken the adhesive strength of the adhesive layer, and the surface of the adhesive layer is covered with the surface of the weakened adhesive layer, and the adherend and the adhesive label There is known an adhesive label that prevents the film from sticking (see Patent Document 2).

  However, in this method, since the pressure-sensitive adhesive layer is weakened by printing the printing ink with a pattern, if the pressure-sensitive adhesive label is used as a transport card for an IC card, the adhesive residue may be generated on the IC card. It was. In addition, even when the adhesive layer is completely non-adhesive by solid printing, static electricity is generated, making it difficult to remove the IC card, or adversely affecting the IC chip built into the IC card. The IC circuit may not operate normally.

By transferring the ink layer to the pressure-sensitive adhesive layer 2 and performing a hollow process, a non-adhesive portion 4 and a divided portion 6 are formed at the center of the surface of the pressure-sensitive adhesive layer 2, and the peripheral portion of the pressure-sensitive adhesive layer 2 The label L for conveyance in which the adhesion part 5 (width | variety 5mm) to stick to was formed was manufactured (planar shape: a rectangle, outer periphery dimension: length 74mm x width 110mm).

(Example 2)
In Example 1, instead of the acrylic pressure-sensitive adhesive (product name “PAT1” manufactured by Lintec Corporation), an acrylic pressure-sensitive adhesive (product name “A118” manufactured by Lintec Corporation) was used, and the base sheet 1 Is a polyethylene terephthalate film (trade name “PET50T38 (QT38)” manufactured by Toray Industries, Inc., thickness 50 μm), and the cured ink layer has a total thickness of 10.6 μm (cured ink having antistatic performance). A transport label L was produced in the same manner as in Example 1 except that the layer thickness was 5.3 μm.

Example 3
In Example 1, instead of the acrylic pressure-sensitive adhesive (product name “PAT1” manufactured by Lintec Corporation), an acrylic pressure-sensitive adhesive (product name “PL Thin” manufactured by Lintec Corporation) was used, and a release sheet ( Instead of Lintec Co., Ltd., trade name “7LK”), a release sheet (Lintech Co., Ltd., trade name “8LK”) was used, and the thickness of the cured ink layer was 11 in total for the two cured ink layers. A transport label L was produced in the same manner as in Example 1 except that the thickness was set to 0.2 μm (the thickness of the cured ink layer having antistatic performance was 5.6 μm).

(Comparative Example 1)
(1) A polyethylene terephthalate film (trade name “PET50 60-T”, thickness 50 μm, manufactured by Toray Industries, Inc.) is prepared as the base sheet 1, and an acrylic pressure-sensitive adhesive is applied to the entire surface of one side of the base sheet 1. (Product name “PAT1” manufactured by Lintec Corporation) was applied and dried to form an adhesive layer 2 (thickness 25 μm), and then a release sheet (manufactured by Lintec Corporation) was formed on the surface of the adhesive layer 2 The release treatment surface of a release sheet) having a trade name “8LK”, high-quality paper laminated with polyethylene terephthalate resin as a supporting substrate and release treatment with a silicone resin was adhered to obtain an adhesive tape.

(2) Next, the pressure-sensitive adhesive tape release sheet obtained in (1) above is peeled off to expose the surface of the pressure-sensitive adhesive layer 2, and a UV curable printing ink (stock) The company name “UV161OP varnish” manufactured by T & K Toka Co., Ltd.) corresponds to the non-adhesive part 4 and the planar shape of the one part 6 extending from the non-adhesive part 4 (the shape shown in FIG. 1). The shape was directly coated by letterpress printing and cured to form a cured ink layer having no antistatic properties.
Subsequently, the non-adhesive part 4 is formed in the center part of the surface of the adhesive layer 2 by bonding the release sheet to the surface of the cured ink layer of the release sheet with the cured ink layer, and the peripheral part of the adhesive layer 2 The label L for conveyance in which the adhesion part 5 (width | variety 5mm) to stick to was formed was manufactured (planar shape: a rectangle, outer periphery dimension: length 74mm x width 110mm).

Judgment Standard for Practical Suitability of Transport Labels The judgment standard for practical suitability of transport labels is shown below.
A: Very good.
○: Good.
X: Inferior.

The transport label L obtained in the example is used to cover the surface of the IC card 9 placed on the surface of the support sheet 8 (material: paper, thickness 133 μm) as shown in FIG. Was attached to the support sheet 8 by the adhesive part 4 to be attached, and the IC card 9 was held on the support sheet 8.
Thereafter, the transport label L was peeled off from the support sheet 8 with an IC card, and the IC card 9 was taken out. The transport label L obtained in the example prevents the generation of static electricity without easily leaving an adhesive on the IC card 9, and can be easily peeled off.

  The transport label of the present invention can be used for coating and sticking various transport components that may generate static electricity when the transport component is coated and pasted and then peeled off.
