Problems solved by technology

In the prior art, the thermal label made of this thermal paper only has the effect of preheating and discoloration. When it is used as an anti-counterfeit label, if the thermal paper is removed, it cannot play an anti-counterfeiting role. It can be seen that the existing Thermal paper anti-counterfeiting labels have defects such as easy removal and poor reliability

Embodiment 1

[0018] This embodiment discloses a thermal label, such as figure 1 As shown, it includes a thermal paper 1, the side of the thermal paper 1 facing away from its heat-sensitive coating is coated with an isolation layer 2, and an ink layer of a preset graphic is printed on the isolation layer 2 3. A glue layer 4 is coated on the ink layer 3 , and a release paper 5 is pasted on the glue layer 4 . Among them, the thermal paper 1 is a primary and three-proof thermal paper with a thickness of 30 μm to 300 μm. The thermal paper 1 includes a thermal coating layer, a coated base paper, and a resin layer stacked sequentially from top to bottom. The resin layer Including but not limited to PP, PE, PET, PVA or other resins.

[0019] When the above thermal label is in use, the release paper 5 is first removed, and then the glue layer 4 side of the thermal label is pasted on the product, wherein the thermal paper 1 is located on the surface layer, and when the thermal coating is heated Di...

Embodiment 2

[0024] Such as figure 2 As shown, the thermal label in this embodiment includes thermal paper 1, isolation layer 2, ink layer 3, glue layer 4 and release paper 5. The difference between this embodiment and Embodiment 1 is that the The isolation layer 2 is a partial isolation layer covering the preset position of the thermal paper 1 .

[0025] The heat-sensitive label of above-mentioned structure, its preparation method comprises the following steps:

[0026] Step S1, using a coating device to coat a release layer 2 on the side of the thermal paper 1 facing away from the thermal coating;

[0027] Step S2, using the printing equipment to print the ink layer 3 of the preset image and text on the isolation layer 2;

[0028] Step S3, coating the glue layer 4 on the ink layer 3;

[0029] In step S4, attach the release paper 5 to the glue layer 4, and then print images and texts on the front side of the thermal paper 1 and die-cut to obtain a finished thermal label.

Abstract

The invention discloses a heat-sensitive label which comprises heat-sensitive paper, wherein an isolation layer is coated on one side, opposite to a heat-sensitive coating, of the heat-sensitive paper; an ink layer with a preset diagram text is printed on the isolation layer; a glue layer is coated on the ink layer; release paper is bonded onto the glue layer. When the heat-sensitive label is used, the release paper is removed first, and then one side, with the glue layer, of the heat-sensitive label is adhered to a product, wherein the heat-sensitive paper is located on the surface layer, when the heat-sensitive coating is heated, the discoloration occurs so as to play the role of information indication and identification, when the heat-sensitive paper is removed, the ink layer is firmly adhered on the product under the action of the glue layer, and represents the preset diagram text so as to achieve a certain anti-counterfeit effect; the ink layer and the glue layer of the heat-sensitive label are unlikely to remove, so that the heat-sensitive label is more reliable.

Description

technical field [0001] The invention relates to a label, in particular to a thermosensitive label and a preparation method thereof. Background technique [0002] Thermal paper is a kind of processed paper. Its manufacturing principle is to coat a layer of heat-sensitive paint on high-quality base paper, that is, a heat-sensitive color-changing layer, which plays the role of information recording in daily use. The production principle of thermal paper is The ordinary paper base is coated with particle powder, and its composition is colorless dye phenol or other acidic substances. When the thermal paper is placed in an environment above 70°C, the thermal coating begins to change color. In the prior art, the thermal label made of this thermal paper only has the effect of preheating and discoloration. When it is used as an anti-counterfeit label, if the thermal paper is removed, it cannot play an anti-counterfeiting role. It can be seen that the existing Thermal paper anti-coun...
