Description

Technical Field

[0001] The utility model relates to an adhesive tape, in particular to a PET decorative adhesive tape with dazzling rainbow light effect. Background Art

[0002] In the existing decorative tape market, the types of products and application scenarios are becoming increasingly diverse, but the development of printing technology is relatively lagging behind. Traditional decorative tapes mainly use four-color printing technology to display patterns and texts. Although this technology can meet basic identification and decoration needs, it lacks innovation and appeal in visual effects. Even in some high-end tape products, although hot stamping and silver stamping processes are used to enhance the grade of the product, these traditional metal texture decorations still cannot meet the market's pursuit of more unique and personalized decorative effects.

[0003] Consumers and the market are no longer looking for functionality alone, but are pursuing a unique visual and sensory experience. They are looking forward to a decorative tape that brings visual impact and emotional resonance in daily use, a product that can show brilliant, splendid, gorgeous, dazzling, and romantic effects under light without the need for any viewing equipment. Utility Model Content

[0004] It is under such a background that the utility model provides a PET decorative tape with dazzling rainbow light effect, and the technical solution adopted is:

[0005] A PET decorative tape with dazzling rainbow light effect comprises a PET base layer, an adhesive layer adhered to the lower surface of the PET base layer, and the adhesive layer is covered by a release layer; a display layer is coated on the upper surface of the PET base layer, and a coating is printed on the upper surface of the display layer. Different from the prior art, the upper surface of the coating is a dazzling rainbow light enhancement layer.

[0006] Further, the dazzling rainbow light enhancement layer is initially located on the hot stamping film and is transferred to the upper surface of the coating by hot stamping or digital cold stamping.

[0007] Furthermore, the bonding layer adopts a removable adhesive, and the annular initial adhesion value is designed to be 5.5N-6.5N / 25mm.

[0008] Furthermore, the release layer is made of transparent PET material, has a thickness of 0.05 mm, a light transmittance between 92.5% and 93.5%, and a haze between 1% and 1.2%.

[0009] Furthermore, the display layer is a UV printing ink layer with a thickness of 10 μm, providing a wear-resistant and colorful surface.

[0010] Furthermore, the coating is tested by contact angle, and the surface tension value of pure water on the PET tape is designed to be between 35 and 38 degrees to optimize the adhesion and leveling effects of the ink.

[0011] Furthermore, the light transmittance of the dazzling rainbow light enhancement layer is greater than 87.5%, and the haze is between 1% and 2%.

[0012] Compared with the prior art, the dazzling rainbow light enhancement layer of the utility model produces a variety of color effects under different lighting conditions through the refraction and reflection of light. These effects may include rainbow-like stripes, shining spots or overall gloss changes, making the surface of the tape present a unique visual effect when viewed from different angles. It not only improves the aesthetics of the tape, but also increases the recognition and uniqueness of the product, bringing a new visual experience and market value to traditional tape products. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0014] The utility model is further described below in conjunction with the accompanying drawings.

[0015] like Figure 1 The PET decorative tape with dazzling rainbow light effect shown in the figure comprises a PET base layer 1, an adhesive layer 2 is adhered to the lower surface of the PET base layer 1, and the adhesive layer 2 is covered by a release layer 6; a display layer 3 is coated on the upper surface of the PET base layer 1, and a coating 4 is printed on the upper surface of the display layer 3, and the upper surface of the coating 4 is a dazzling rainbow light enhancement layer 5.

[0016] The rainbow light enhancement layer is usually composed of optically active film materials that can produce rainbow-like color effects through optical interference, diffraction or reflection principles. These film materials may include, but are not limited to, PET (polyethylene terephthalate) film, PVC (polyvinyl chloride) film or other transparent plastic films, which are designed to have a specific thickness and surface structure to achieve the desired optical effect. The rainbow light enhancement layer 5 is initially located on the hot stamping film and transferred to the upper surface of the coating 4 by hot stamping or digital cold stamping. Hot stamping technology involves transferring a pre-made rainbow light hot stamping film to the coating by hot pressing. The advantages are bright colors, good durability and mature technology; the disadvantages are high energy consumption, limited production speed and possible impact on the environment. Digital cold stamping technology is a process that does not require heating. It uses special printing equipment to directly create a rainbow light effect on the coating. The advantages are environmental protection, flexible design and high production efficiency. The disadvantages are that the cost may be high, the technical requirements are high, and the color effect may be slightly inferior to hot stamping.

[0017] The adhesive layer is the core functional layer of the tape, responsible for providing adhesion so that the tape can be firmly attached to various surfaces. The adhesive layer 2 uses a removable adhesive, and the ring initial adhesion value is designed to be 5.5N-6.5N / 25mm. It has good adhesive properties and appropriate viscosity, can provide a stable bonding effect on surfaces of different materials, and is removable to avoid leaving residual adhesive.

[0018] The release layer 6 is made of transparent PET material with a thickness of 0.05 mm, a light transmittance between 92.5% and 93.5%, and a haze between 1% and 1.2%. The isolation layer is located outside the adhesive layer. Its main function is to protect the adhesive layer from being contaminated or damaged. At the same time, it also serves to isolate the chemical reaction that may occur between the adhesive layer and the dazzling rainbow light enhancement layer after the tape is wound. It not only provides physical protection, but also maintains the transparency and optical properties of the tape, ensuring the complete display of the dazzling rainbow light effect.

[0019] The display layer 3 is used to display patterns, colors and designs, and is the part that users directly touch and visually perceive. It is a UV printing ink layer with a thickness of 10 μm. The display layer made of UV printing ink or other wear-resistant materials not only provides rich colors and clear patterns, but also has excellent wear resistance and weather resistance, ensuring beauty and durability in long-term use.

[0020] The coating 4 has been tested by contact angle, and the surface tension of pure water on the PET tape is designed to be between 35-38 degrees to optimize the adhesion and leveling effect of the ink. The coating is part of the display layer, which provides a uniform printing surface for the ink to ensure uniform coating and firm adhesion of the ink. The coating is treated with special treatments such as UV curing to enhance the adhesion and wear resistance of the ink, while providing good color expression, making the pattern and design of the tape more vivid and durable.

[0021] The light transmittance of the dazzling rainbow light enhancement layer 5 is greater than 87.5%, and the haze is between 1% and 2%. This layer is applied by hot stamping or digital cold stamping process, and contains micro-optical elements or interference film technology, which can produce brilliant, splendid, gorgeous, dazzling, and romantic visual effects under light irradiation at different angles, greatly improving the decorativeness and visual appeal of the tape.
