Description

Technical Field

[0001] The utility model relates to the technical field of tape printing, in particular to a finished PET decorative tape with naked eye 3D pearlescent effect. Background Art

[0002] Existing decorative tapes can be divided into warning tapes, carpet tapes, sealing tapes, notebook tapes, etc. according to their application scope. The printing process on the surface of the tapes is traditional four-color printing.

[0003] For example, the utility model patent with publication number CN204242513U discloses a self-adhesive label with identification function, including a substrate surface layer, an ink layer and a glue layer formed from top to bottom, wherein a release layer and a printing coating layer are sequentially arranged from top to bottom between the substrate surface layer and the ink layer, and the adhesion between the ink layer and the glue layer is greater than the adhesion between the ink layer and the printing coating layer. Since the adhesion between the ink layer and the glue layer is greater than the adhesion between the ink layer and the printing coating layer, the ink layer will not be removed from the surface of the object due to peeling off the substrate surface layer, thereby effectively ensuring the integrity of the identification pattern on the ink layer and the adhesion effect.

[0004] However, when the above-mentioned types of tapes are used for decoration, the surface of the tape itself has no sense of added layers, and the printing effects are all 2D flat effects without bright spots. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a PET decorative tape with naked-eye 3D pearlescent effect. The 3D pearlescent effect can be viewed on the surface of the finished tape without the aid of any observation equipment. Compared with the 2D effect, the color is more vivid, the pattern is richer, and the decorative effect is better.

[0006] To achieve the above-mentioned purpose, the present application discloses a finished PET decorative tape with naked-eye 3D pearlescent effect, comprising a 3D pearlescent digital enhancement layer, a printed coating, a display layer, an adhesive layer and a release layer stacked together from top to bottom, wherein the 3D pearlescent digital enhancement layer is a printed ink layer having 3D pearlescent hot stamping elements on the surface, the printed coating has a thickness of 0.005 mm, the display layer is a UV printing ink with a thickness of 10 μ, the bonding layer is an adhesive layer with removable oil glue properties, and the release layer is an optical-grade PET film with a thickness of 0.05 mm.

[0007] The surface tension of the finished PET decorative tape is 35-38 N / m.

[0008] Furthermore, the annular initial adhesion value of the adhesive layer is 5.5N-6.5N / 25mm, and the 180° peeling force value is 4-5N / 25mm.

[0009] Furthermore, the optical-grade PET film of the release layer has a light transmittance of 92.5%-93.5% and a haze of 1%-1.2%.

[0010] Furthermore, the overall light transmittance of the pearlescent digital enhancement layer, printed coating, display layer and adhesive layer is greater than 87.5%, and the haze is 1%-2%.

[0011] Beneficial effects of the technical solution of the utility model

[0012] This application uses a 3D pearlescent digital enhancement layer in the tape to innovate the display effect of digital enhancement from 2D to naked-eye 3D. The 3D pearlescent process product effect is the first in the industry. In the design of super-transparent materials, the transmittance and haze design scheme of the display layer and the release layer are protected; the material is super-transparent optical-grade PET to better display and present the printing effect on the surface of the tape; the adhesive uses a removable oil-based adhesive design scheme, and there will be no glue flower phenomenon of water-based adhesive, such as affecting the overall transmittance and haze of the tape, so that the tape can be left on the surface of the bonded material without residual glue and damaging the material effect; the stiffness of the tape is significantly improved compared to the traditional substrate, and the texture of the substrate is harder, with properties such as wear resistance, anti-fouling, high temperature and high humidity resistance, low temperature resistance, UV resistance and salt spray corrosion resistance.
