Description

Technical Field

[0001] The utility model relates to the technical field of release paper, in particular to a paper sticker for preventing the release paper from reverse release. Background Art

[0002] Conventional paper stickers, such as Figure 1 and Figure 2 shown, are composed of a heavy release film 111 and a protection paper 113 body spliced into a large light release film 112. It mainly includes a heavy release film 111, a protection paper 112 and a light release film 112. Among them, the release force of the heavy release film 111 is greater than that of the light release film 112, and it is easy to separate from the protection paper 113. The protection paper 113 has single-sided adhesiveness, and the adhesive surface faces the light release film 112. The light release film 112 has a relatively small release force during peeling and is easy to separate from the protection paper 113. However, during employee operation, the heavy release film 111 and the light release film 112 often stick together and cannot be separated, or as Figure 2 shown, when the heavy release film 111 is torn off, in the case of a relatively large adhesiveness of the protection paper 113, the light release film 112 is not easy to separate from the protection paper 113, and a reverse release state will occur, that is, the heavy release film 111 cannot lift the protection paper 113. This phenomenon is usually called reverse release. Once it occurs, the customer will not be able to use it. Content of the Utility Model

[0003] Based on this, in view of the above technical problems, it is necessary to provide a paper sticker for preventing the release paper from reverse release. By increasing the adhesiveness of the heavy release film, the adhesiveness requirement of the heavy release film is ≥150 g, and reducing the adhesiveness of the light release film, the adhesiveness requirement of the light release film is ≤50 g. At this time, during employee operation, since the adhesiveness between the heavy release film and the protection paper is greater than the adhesiveness between the light release film and the protection paper, the protection paper will be lifted after the heavy release film is torn off, and the light release film can be directly separated from the protection paper, thus avoiding the reverse release state and enabling the customer to use it better.

[0004] In order to solve the above technical problems, the utility model adopts the following technical scheme:

[0011] Further, a plurality of through holes are formed in the non-adhesive film, and the through holes are circular structures.

[0012] Further, a moisture-proof ring is fixedly connected to one side edge of the heavy release film close to the light release film. The other side of the moisture-proof ring is attached to the light release film. The protective paper is smaller than the heavy release film, and the protective paper is located inside the moisture-proof ring.

[0013] Further, the moisture-proof ring is a rectangular structure with a width of 2-3 mm, and the thickness of the moisture-proof ring is 1 / 2 of the thickness of the heavy release film.

[0014] Further, the moisture-proof ring is composed of a composite of activated carbon fibers and water-absorbing fibers.

[0015] Further, a nano silver antibacterial coating is provided on the lower surface of the moisture-proof ring, and a waterproof layer is provided on the upper surface of the heavy release film. The thicknesses of the nano silver antibacterial coating and the waterproof layer are both 0.1-0.2 mm.

[0028] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0029] As described in the background art, for the existing paper sticker with a heavy release film, when the adhesion of the protective paper is relatively large, the light release film is not easily separated from the protective paper, and a reverse release state will occur, resulting in the problem that the customer cannot use it.

[0030] To solve this technical problem, the present utility model provides a paper sticker for preventing reverse release of the protective paper. By increasing the adhesion of the heavy release film 1 and reducing the adhesion of the light release film 2, the protective paper 3 can be lifted after the heavy release film 1 is torn off, avoiding the occurrence of the reverse release state.

[0031] Specifically, please refer to Figure 2-6 , the paper sticker for preventing reverse release of the protective paper specifically includes:

[0032] A heavy release film 1, a light release film 2 and a protective paper 3. The protective paper 3 is arranged between the heavy release film 1 and the light release film 2. The adhesion of the heavy release film 1 is greater than 150 g, the adhesion of the light release film 2 is less than 50 g, and a non-adhesive film 4 is fixedly connected to one end of the heavy release film 1.

[0033] For the paper sticker for preventing reverse release of the protective paper provided by the present utility model, by increasing the adhesion of the heavy release film 1, the adhesion requirement of the heavy release film 1 is ≥150 g, and by reducing the adhesion of the light release film 2, the adhesion requirement of the light release film 2 is ≤50 g. At this time, during the operation of the employee, since the adhesion between the heavy release film 1 and the protective paper 3 is greater than the adhesion between the light release film 2 and the protective paper 3, the protective paper 3 will be lifted after the heavy release film 1 is torn off, and the light release film 2 can be directly separated from the protective paper 3, thus avoiding the occurrence of the reverse release state. By adding a non-adhesive PET material as a spacer tape at the left and right ends of the heavy release film 1 to form the non-adhesive film 4, in this way, the employee can first tear off the non-adhesive film 4 during operation, and then lift the heavy release film 1 and the protective paper 3 to separate the heavy release film 1 from the light release film 2, so as to facilitate tearing off the heavy release film 1 and lifting the protective paper 3, and better separate the heavy release film 1 from the light release film 2.

[0034] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

[0035] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0036] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0037] Please refer to Figure 2-6A paper sticker for preventing a protective paper from releasing from the substrate, comprising a heavy release film 1, a light release film 2 and a protective paper 3, wherein the protective paper 3 is arranged between the heavy release film 1 and the light release film 2, wherein the viscosity of the heavy release film 1 is greater than 150g, the viscosity of the light release film 2 is less than 50g, and one end of the heavy release film 1 is fixedly connected with a non-sticky film 4.

[0038] Please refer to Figure 3 and Figure 4 By increasing the viscosity of the heavy release film 1, so that the viscosity requirement of the heavy release film 1 is ≥150g, and reducing the viscosity of the light release film 2, so that the viscosity requirement of the light release film 2 is ≤50g, at this time, when the employee is operating, because the viscosity between the heavy release film 1 and the protective paper 3 is greater than the viscosity between the light release film 2 and the protective paper 3, the protective paper 3 will be pulled up after the heavy release film 1 is torn off, and the light release film 2 can be directly separated from the protective paper 3, thereby avoiding the reverse release state.

[0039] The paper sticker for preventing the protective paper from releasing from the back provided in this embodiment forms a non-sticky film 4 by adding non-sticky PET material as an isolation tape at the left and right ends of the heavy release film 1. In this way, when operating, the employee can tear off the non-sticky film 4 first, and then lift up the heavy release film 1 and the protective paper 3 to separate the heavy release film 1 from the light release film 2, thereby facilitating the tearing off of the heavy release film 1 and lifting up the protective paper 3, and better separating the heavy release film 1 from the light release film 2.

[0040] The paper sticker for preventing the protective paper from releasing from the mold provided in Example 1 is further optimized. Specifically, Figure 3 As shown, the protective paper 3 is sticky on one side, and the stickiness of the protective paper 3 faces one side of the light release film 2; there are two non-sticky films 4, which are fixedly connected to both ends of the heavy release film 1, and the non-sticky films 4 are made of PET material.

[0041] The above structural design allows the non-adhesive film 4 to be peeled off from both sides thereof. Meanwhile, the non-adhesive film 4 made of PET material is non-toxic and has better performance, thereby being able to tear off the heavy release film 1 and bring up the protective paper 3 more easily, making it more convenient to use.

[0042] The paper sticker for preventing the protective paper from releasing from the mold provided in Example 1 or 2 is further optimized, such as Figure 3 and Figure 4 As shown, there is one light release film 2, and there are multiple heavy release films 1 and protective papers 3. The multiple heavy release films 1 are all strip-shaped and evenly pasted on the light release film 2. The non-adhesive film 4 is provided with multiple through holes 401, and the through holes 401 are circular in structure.

[0043] Such a setting includes a large piece of light release film 2, multiple pieces of heavy release film 1, and multiple pieces of protective paper 3 bodies. The multiple pieces of heavy release film 1 are spliced onto a large piece of light release film 2, and each protective paper 3 body is located between the light release film 2 and the heavy release film 1. Generally, ten pieces of heavy release film 1 and protective paper 3 are spliced onto one piece of light release film 2. Multiple heavy release films 1 and protective papers 3 can be set at one time, which is more convenient to use. At the same time, the through holes 401 on the non-adhesive film 4 can increase the friction between the operator's hand and the non-adhesive film 4, avoiding the phenomenon of hand slipping when uncovering the non-adhesive film 4.

[0044] The paper sticker for preventing the reverse release of the protective paper provided in the above embodiments is further optimized. For example, Figure 4 and Figure 5 As shown, a moisture-proof ring 5 is fixedly connected to the edge of the side of the heavy release film 1 close to the light release film 2. The other side of the moisture-proof ring 5 is attached to the light release film 2. The protective paper 3 is smaller than the size of the heavy release film 1, and the protective paper 3 is located inside the moisture-proof ring 5;

[0045] The moisture-proof ring 5 is of a rectangular structure with a width of 2 - 3 mm. The thickness of the moisture-proof ring 5 is 1 / 2 of the thickness of the heavy release film 1. The moisture-proof ring 5 is composed of a composite of activated carbon fibers and water-absorbing fibers. A nano-silver antibacterial coating 6 is provided on the lower surface of the moisture-proof ring 5, and a waterproof layer 7 is provided on the upper surface of the heavy release film 1. The thicknesses of both the nano-silver antibacterial coating 6 and the waterproof layer 7 are 0.1 - 0.2 mm.

[0046] With such a structural design, by fixedly connecting the moisture-proof ring 5 to the edge of the side of the heavy release film 1 close to the light release film 2, and at the same time, a nano-silver antibacterial coating 6 is provided on the lower surface of the moisture-proof ring 5 and a waterproof layer 7 is provided on the upper surface of the heavy release film 1, the protective paper 3 between the heavy release film 1 and the light release film 2 can be well protected to prevent bacteria from entering. At the same time, the moisture-proof ring 5 will adsorb the moisture in the air, reducing the contact between the moisture entering between the heavy release film 1 and the light release film 2 and the protective paper 3, realizing moisture-proof for the protective paper 3.

[0047] The using process of the paper sticker for preventing the reverse release of the protective paper provided by the present utility model is as follows:

[0048] For example, Figure 3 and Figure 4As shown in the figure, it includes a large piece of light release film 2, multiple pieces of heavy release films 1, and multiple pieces of protective paper 3 bodies. The multiple pieces of heavy release films 1 are spliced onto a large piece of light release film 2, and each protective paper 3 body is located between the light release film 2 and the heavy release film 1. Generally, ten pieces of heavy release films 1 and protective paper 3 are spliced onto one piece of light release film 2. In this utility model, by increasing the adhesiveness of the heavy release film 1, the adhesiveness requirement of the heavy release film 1 is ≥150 g, and by reducing the adhesiveness of the light release film 2, the adhesiveness requirement of the light release film 2 is ≤50 g. At this time, when an employee operates, since the adhesiveness between the heavy release film 1 and the protective paper 3 is greater than the adhesiveness between the light release film 2 and the protective paper 3, the protective paper 3 will be lifted after the heavy release film 1 is torn off, and the light release film 2 can be directly separated from the protective paper 3, thus avoiding the reverse release state; because the adhesiveness of the heavy release film 1 is increased, although the employee can ensure that the heavy release film 1 lifts the protective paper 3 every time during operation, the adhesiveness of the heavy release film 1 will also act on the light release film 2, which is not conducive to the tearing operation of the heavy release film 1. By adding non-adhesive PET materials as anti-sticking tapes at the left and right ends of the heavy release film 1 to form non-adhesive films 4, in this way, when an employee operates, the non-adhesive films 4 can be torn off first, and then the heavy release film 1 and the protective paper 3 can be lifted, separating the heavy release film 1 from the light release film 2, thus facilitating the tearing of the heavy release film 1 and lifting the protective paper 3, and better separating the heavy release film 1 from the light release film 2;

[0049] As Figure 4 and Figure 5 shown in the figure, by fixedly connecting a moisture-proof ring 5 to the edge of the heavy release film 1 close to the light release film 2, and at the same time, a nano-silver antibacterial coating 6 is provided on the lower surface of the moisture-proof ring 5, and a waterproof layer 7 is provided on the upper surface of the heavy release film 1. In this way, the protective paper 3 between the heavy release film 1 and the light release film 2 can be well protected to prevent bacteria from entering. At the same time, the moisture-proof ring 5 will adsorb the moisture in the air, reducing the contact between the moisture entering between the heavy release film 1 and the light release film 2 and the protective paper 3, realizing the moisture-proof of the protective paper 3.
