[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] To address the technical problem in existing thermal transfer labels where printed or handwritten content is exposed on the label surface, making the label susceptible to corrosion from air, water, oil, and other substances, thus affecting the display of the label content, this utility model provides a thermal transfer label that can cover the printing unit with a protective layer to isolate it from air, water, oil, and other substances, thereby protecting the printing unit.

[0027] Please see Figure 1 , Figure 1This is a schematic diagram of the structure of a heat transfer label in one embodiment of the present invention. The heat transfer label 100 includes a base release layer 1, a laminating unit 2, and a printing unit 3. The laminating unit 2 includes a protective layer 22, which may be, for example, a transparent PET film. The protective layer 22 is disposed on the base release layer 1 and is detachably connected to the base release layer 1. One side of the printing unit 3 is detachably connected to the base release layer 1, and the other side of the printing unit 3 is used to print information, which may be text, numbers, or patterns. The printing unit 3 can be combined with the side of the laminating unit 2 opposite to the base release layer 1 to cover the printing unit 3 with the protective layer 22. Specifically, the base release layer 1 can be folded in half to combine the laminating unit 2 with the printing unit 3, or the base release layer 1 can be broken so that the laminating unit 2 and the printing unit 3 are not located on the same base release layer 1, and then the protective layer 22 can be covered with the printing unit 3.

[0028] In one embodiment, please refer to Figure 1 The release layer 1 has a symmetrically arranged film-coating area 11 and a printing area 12. The film-coating unit 2 also includes a first adhesive layer 21 and a second adhesive layer 23. The first adhesive layer 21, the protective layer 22, and the second adhesive layer 23 are stacked sequentially, and the first adhesive layer 21 adheres to the film-coating area 11. The printing unit 3 includes a third adhesive layer 31 and a label layer 32. The third adhesive layer 31 adheres to the printing area 12. One side of the label layer 32 is adhered to the third adhesive layer 31, and the other side of the label layer 32 can be bonded to the side of the second adhesive layer 23 opposite to the protective layer 22.

[0029] In this embodiment, the laminating unit 2 is detachably disposed in the laminating area 11 via the first adhesive layer 21, and the printing unit 3 is detachably disposed in the printing area 12 via the third adhesive layer 31. When the release layer 1 is folded over to combine the laminating area 11 and the printing area 12, the laminating unit 2 and the printing unit 3 can be stacked together. The label layer 32 can be connected to the second adhesive layer 23 when the laminating area 11 and the printing area 12 are folded together. At this time, the protective layer 22 covers the label layer 32 and can protect the label layer 32. The label layer 32 can be customized with identification information that combines text, patterns, and colors to facilitate identification.

[0030] In one embodiment, the first adhesive layer 21 is AB double-sided adhesive, with different adhesive strengths on both sides. The side with stronger adhesiveness is bonded to the film-coated area 11, and the side with weaker adhesiveness is bonded to the protective layer 22. When the bottom release layer 1 is flipped and folded, it needs to be peeled off. During the peeling process, because the side with stronger adhesiveness is bonded to the film-coated area 11 (bottom release layer 1), the bottom release layer 1 can easily pull the AB double-sided adhesive away from the protective layer 22.

[0031] In one embodiment, the adhesive force between the third adhesive layer 31 and the label layer 32 is greater than the adhesive force between the third adhesive layer 31 and the backing release layer 1. In this embodiment, when the laminating area 11 and the printing area 12 are folded together, the laminating unit 2 and the printing unit 3 combine. It is necessary to first peel the backing release layer 1 away from the third adhesive layer 31 and then adhere the third adhesive layer 31 to the label mounting position. In this embodiment, the adhesive force between the third adhesive layer 31 and the label layer 32 is greater than the adhesive force between the third adhesive layer 31 and the backing release layer 1. Therefore, during the process of peeling the backing release layer 1 away from the third adhesive layer 31, the third adhesive layer 31 will not detach from the label layer 32, allowing the label layer 32 to be adhered to the label mounting position via the third adhesive layer 31.

[0032] In one embodiment, the protective layer 22 is a transparent PET film. The transparent PET film does not affect the visibility of the label layer 32. The PET film also has good heat resistance, cold resistance, corrosion resistance and oil resistance, which can provide stable protection for the label layer 32 so that the label layer 32 can be used for a long time.

[0033] In one embodiment, both the second adhesive layer 23 and the third adhesive layer 31 are pressure-sensitive adhesives. The pressure-sensitive adhesive of the second adhesive layer 23 is mainly used to connect the protective layer 22 to the label layer 32 after the bottom release layer 1 is flipped and folded, so that the protective layer 22 can protect the label layer 32. The pressure-sensitive adhesive of the third adhesive layer 31 is mainly used to adhere to a fixed mounting position after the bottom release layer 1 is peeled off, such as on the product surface or a wall.

[0034] In one embodiment, please refer to Figure 1 The printing unit 3 also includes a printed pattern layer 33, which is adhered to the side of the label layer 32 facing away from the third adhesive layer 31. The printed pattern layer 33 can connect to the second adhesive layer 23 when the laminating area 11 and the printing area 12 are folded together, so that the protective layer 22 covers the printed pattern layer 33, providing protection for both the printed pattern layer 33 and the label layer 32. In this embodiment, the printed pattern layer 33 can be a transparent sticker with a pattern, used to connect and bond with the label layer 32, adding information elements to the label layer 32 for better label identification. Alternatively, the printed pattern layer 33 can also be a handwritten sticker, allowing information to be added to the printed pattern layer 33 by handwriting, accommodating the need for handwritten labels before lamination, and increasing the flexibility of use.

[0035] In one embodiment, please refer to Figure 4The release layer 1 has a fold-off tear line 13, and the film-coated area 11 and the printing area 12 are symmetrical about the fold-off tear line 13. In this embodiment, by setting the fold-off tear line 13, the film-coated area 11 and the printing area 12 of the release layer 1 can be easily folded over and flipped through the fold-off tear line 13, so that the film-coated area 11 and the printing area 12 are combined, and the film-coated unit 2 and the printing unit 3 are attached together.

[0036] In one embodiment, please refer to Figure 1 The coating unit 2 also includes a release paper 24, which is attached to the side of the second adhesive layer 23 facing away from the protective layer 22. In this embodiment, by providing the release paper 24 to cover the second adhesive layer 23, the second adhesive layer 23 is protected, preventing it from coming into contact with too much dust before use, which would weaken its adhesiveness.

[0037] Further, please refer to Figure 2 One end of the release paper 24 is not covered by the second adhesive layer 23, while the other end of the release paper 24 is completely adhered to the second adhesive layer 23. In this embodiment, the area of ​​the release paper 24 is slightly smaller than the area of ​​the second adhesive layer 23 so that the release paper 24 can be quickly torn off to detach from the second adhesive layer 23.

[0038] In another embodiment, please refer to Figure 3 The release paper 24 includes a non-connected first portion 241 and a second portion 242, which together cover all parts of the second adhesive layer 23. In this embodiment, the first portion 241 and the second portion 242 are separated by a solid slit line 243. Compared to the previous embodiment, this embodiment only adds a second portion 242. The first portion 241 of this embodiment can be considered as the release paper 24 of the previous embodiment. The second portion 242 completely covers the uncovered parts of the second adhesive layer 23 in the previous embodiment, thereby improving the protection of the second adhesive layer 23. All parts of the second adhesive layer 23 will not come into contact with dust before use, maintaining good adhesion, and also making the release paper 24 easy to tear.

[0039] Please see Figure 4 This utility model also provides a label roll 200, including a roller 4 and a plurality of the above-mentioned heat transfer labels 100. The plurality of heat transfer labels 100 are connected in sequence by tear lines 5 and wound around the roller 4 so that the label roll 200 can store a plurality of heat transfer labels 100. When using the heat transfer labels 100, it is only necessary to tear open the tear lines 5 between adjacent heat transfer labels 100 or cut them with scissors, which is convenient to use.

[0040] To better understand this utility model, the following is combined with... Figures 1 to 4 The technical solution of this utility model is described in detail below:

[0041] In use, the heat transfer label 100 of this utility model is first peeled off the release paper 24 to expose the second adhesive layer 23. The backing release layer 1 is then folded in half to bond the second adhesive layer 23 to the printed pattern layer 33. The laminating unit 2 and the printing unit 3 are then stacked together. Next, the backing release layer 1 is completely peeled off, causing the first adhesive layer 21 to detach from the protective layer 22, exposing the protective layer 22. The printed pattern layer 33 and the label layer 32 covered by the protective layer 22 can be clearly seen through it. Finally, the third adhesive layer 31 is pasted into the mounting position to complete the installation of the heat transfer label. It should be emphasized that before labeling, one or more layers of the printed pattern layer 33 can be selectively applied to the label layer 32, or the printed pattern layer 33 can be left unapplied, accommodating lamination requirements and offering flexible options.

[0042] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
