Embodiment 1

[0197] Example 1: RFID anti-counterfeiting label with UV-curable adhesive film

[0198] The RFID anti-counterfeiting label is composed of the following three layers: 1) PET surface material layer with RFID printed circuit and chip; 2) UV-curable adhesive film; 3) PET release film (Xiamen long days).

[0199] The RFID anti-counterfeiting label is made of a PET surface material layer with an RFID printed circuit and a chip attached to a UV-curable adhesive film on a PET release film.

[0200] Operation: 1) Irradiate 1.0-2.0J / cm through the PET release film 2 UV light with a wavelength of 260 to 380nm; 2) Peel off the PET release film within 5 minutes of open time, and stick the label on the substrate to be pasted; 3) The film is cured after 72 hours at room temperature. The label parameters, usage conditions and experimental results of Example 1 are shown in Table 6.

Embodiment 2

[0205] The RFID and laser holographic anti-counterfeit labels with UV-curable adhesive film were prepared according to Example 1, the difference being that: the UV-curable adhesive film contained EVA components, and the anti-counterfeit surface material layer was RFID and laser holographic surface material layer.

[0206] The anti-counterfeiting label is composed of the following three layers: 1) PET surface material layer or laser holographic surface material layer with RFID printed circuit and chip; 2) UV-curable adhesive film; 3) PET surface material layer that can transmit ultraviolet light Release film (Xiamen Changtian).

[0207] The PET surface material or laser holographic surface material with RFID circuit and chip is directly attached to the adhesive film surface of the PET release film with adhesive film to obtain a UV-curable adhesive film; and PET release film RFID anti-counterfeiting labels or laser holographic anti-counterfeiting labels.

Embodiment 3

[0212] Example 3: Laser holographic anti-counterfeiting label with UV-curable adhesive film

[0213] A laser holographic anti-counterfeiting label with a UV-curable adhesive film was prepared according to Example 1, except that the UV-curable adhesive film contained methacrylate, and the anti-counterfeit surface material layer was a laser holographic surface material layer.

[0214] The laser holographic anti-counterfeiting label structure with UV-curable adhesive film consists of the following three layers: 1) laser holographic anti-counterfeiting surface material (PET and paper); 2) UV-curable adhesive film; and 3) UV-transmissible PET release film (Micron) with a thickness of 50 μm.

[0215] The PET or paper surface material with the laser holographic anti-counterfeiting function label is directly attached to the adhesive film surface of the PET release film with the adhesive film, and the laser holographic anti-counterfeiting with the UV-curable adhesive film and the PET r...

Abstract

The invention provides an anti-counterfeiting label with an ultraviolet-cured glue film. The anti-counterfeiting label comprises: (1) a surface material layer with an anti-counterfeiting function, (2) an ultraviolet-cured glue film which is attached to the surface material layer, and (3) a release material layer which is attached to the glue film and through which ultraviolet light can pass. The label cannot be peeled or removed completely after use, so that the possibility of repeated use is avoided, and an anti-counterfeit characteristic is realized.

Description

technical field [0001] The invention relates to an adhesive and an anti-counterfeit mark. More specifically, the present invention relates to an anti-counterfeiting label with an ultraviolet light curing adhesive film. Background technique [0002] Labels with pressure-sensitive adhesives are easy to be peeled off, removed or reused due to the limited cohesive force of pressure-sensitive adhesives. Therefore, even if such labels have anti-counterfeiting identification technology, their anti-counterfeiting capabilities (reusable ) is also greatly reduced in actual use. [0003] On the other hand, some labels use heat-cured adhesives instead of pressure-sensitive adhesives. Although the bonding strength of this thermosetting glue can meet the requirements of use, it needs high temperature curing, which is inconvenient to use and operation. At the same time, it needs to be stored at low temperature before use, and the shelf life is also very short. Therefore, the application...
