Description

Technical Field

[0001] The present application relates to a laser-etched label, belonging to the field of laser etching. Background Art

[0002] Modern society uses QR code labels in a wide range of scenarios, such as payment, merchant promotion, vehicle management, electronic ordering, scan code login, and other scenarios. Existing, widely used QR codes are printed and then laminated. However, these laminated codes typically need to be placed in a fixed location or punched and hung. These methods also require secondary processing of the printed QR code. Furthermore, the printed QR code is prone to becoming unclear or fading due to long-term use of the ink. Therefore, a new laser-etched label has become a pressing issue for those skilled in the art. Utility Model Content

[0003] According to one aspect of the present application, a label that can be laser etched is provided by forming a first color coating layer, a separation layer and a second color coating layer. It is usually used when a QR code label is required. The QR code label is etched by laser and can be pasted.

[0004] The present application provides a laser-etched label, comprising: an etching layer, an adhesive layer, and an anti-sticking layer arranged in sequence from top to bottom;

[0005] The etching layer is used for laser etching, and the etching layer further comprises a first color coating layer, a separation layer and a second color coating layer;

[0006] The first color coating layer and the second color coating layer are respectively arranged at the upper and lower ends of the separation layer;

[0007] The adhesive layer is used for pasting laser-etched labels;

[0008] The anti-sticking layer is used to isolate the adhesive layer from contact with the outside.

[0009] Optionally, the first color coating layer is black photosensitive resin ink.

[0010] Optionally, the separation layer is a stripping varnish.

[0011] Optionally, the second color coating layer is white latex.

[0012] Optionally, the adhesive layer is a PET material with a solvent adhesive at the bottom.

[0013] Optionally, the anti-sticking layer is a release paper, and the release paper is bonded to the bottom of the adhesive layer.

[0014] The beneficial effects of this application include:

[0015] The etching layer provided in the present application includes a first color coating layer, a separation layer and a second color coating layer. The separation layer is a stripping varnish. During laser etching, the first color coating layer is etched according to the designed QR code shape or other marking shape, so that the second color coating layer is visible. After the etching is completed, the second color coating layer and the first color coating layer form a sharp contrast, making the QR code label clear and not easy to fade, having a longer service life, and the label is more three-dimensional.

[0019] In order to make the purpose, technical solution, design method and advantages of the present invention more clear, the present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention and are not intended to limit the present invention.

[0020] like Figure 1 As shown, the present application provides a laser etching label, comprising: an etching layer 1, an adhesive layer 2 and an anti-sticking layer 3 arranged in sequence from top to bottom;

[0021] The etching layer 1 is used for laser etching, and the etching layer 1 further comprises a first color coating layer 4, a separation layer 5 and a second color coating layer 6;

[0022] The first color coating layer 4 and the second color coating layer 6 are respectively arranged at the upper and lower ends of the separation layer 5;

[0023] The first color coating layer 4 is black photosensitive resin ink.

[0024] The separation layer 5 is a stripping varnish.

[0025] The second color coating layer 6 is white latex.

[0026] The adhesive layer 2 is used for pasting laser-etched labels, and the adhesive layer 2 is made of PET material with solvent glue at the bottom.

[0027] The anti-adhesive layer 3 is used to isolate the adhesive layer 2 from contact with the outside. The anti-adhesive layer 3 is a release paper, and the release paper is bonded to the bottom of the adhesive layer 2.

[0028] During production, the label is prepared on top of the adhesive layer 2 (i.e., PET material). The upper layer of the adhesive layer 2 is coated with white latex, which serves as the second color coating layer 6. A peeling varnish is then applied to the upper layer of the white latex, and the upper layer of the peeling varnish is then coated with black photosensitive resin ink. During laser etching, the black photosensitive resin ink is removed according to the designed label shape, revealing the white latex layer at the bottom. The black and white colors form a sharp contrast, forming a QR code label or other label requiring two-color contrast.

[0029] It should be noted that the first color coating layer 4 and the second color coating layer 6 may also be made of other inks with sharp contrasting colors.

[0030] Please refer to Figure 2 As shown, the laser etched label is a whole label 7 that can be etched. Several etching areas 8 are arranged on the whole label 7. After laser etching on the etching areas 8, a QR code label or other label is formed. After the whole label is laser etched, it can be cut and used.

[0031] The above descriptions are merely a few embodiments of the present application and do not constitute any form of limitation to the present application. Although the present application discloses the preferred embodiments as above, they are not intended to limit the present application. Any technical personnel familiar with the present profession, without departing from the scope of the technical solution of the present application, using the technical content disclosed above to make slight changes or modifications are equivalent to equivalent implementation cases and fall within the scope of the technical solution.
