Description

Technical Field

[0001] The utility model relates to the technical field of release film main body, in particular to a release film which is easy to tear off. Background Art

[0002] Release film, also known as peeling film, separation film, slip film, etc., is widely used in various industries, especially in printing and electronic products. The surface of electronic products is often covered with a layer of release film, which is convenient for protecting precision parts such as electronic screens, and can also effectively prevent the surface of electronic screens from being scratched. When release film is widely used, there is a problem of unchanged use, that is, it is not easy to tear and peel off quickly. Long-term integrated use with electronic products or other products will lead to poor heat dissipation, short circuit, short life and other problems.

[0003] The existing release film is not easy to tear off and peel off. For example, the PVC release film disclosed by publication number CN216106755U includes an adhesive layer, a fireproof layer is fixedly bonded on the top of the adhesive layer, and the material of the fireproof layer is glass fiber. A heat-resistant layer is fixedly bonded on the lower end of the fireproof layer, and the material of the heat-resistant layer is silicone coating. The thickness of the fireproof layer is greater than that of the heat-resistant layer. The fireproof layer reduces the damage caused by fire to it and improves the fire resistance. The heat-resistant layer blocks the heat to prevent the bonding part from melting and degumming due to the action of heat. The anti-static layer prevents the harm of static electricity in autumn and winter and improves the safety of the release film. The rubber layer improves the waterproof ability and the scratch-resistant layer improves the scratch resistance of the release film. However, when the release film needs to be peeled off from the base paper, there is no warped part, and it is not easy to be peeled off at one time.

[0004] Therefore, it is necessary to invent a release film that is easy to tear off to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a release film which is easy to tear off, so as to solve the problem that the release film body is not easy to be quickly peeled off from the base paper in the prior art.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a release film that is easy to tear off, comprising a heavy-duty base paper, an anti-static layer, a release film body and a vacuum chamber, wherein the heavy-duty base paper is tightly attached to the release film body through the anti-static layer, a vacuum chamber is opened at each corner of the release film body, bubbles are injected into the vacuum chamber, and the vacuum chamber, bubbles and the sides of the release film body are wrapped with edge sealing paper.

[0007] Preferably, the vacuum chamber is filled with inert gas, and the gas in the bubbles is of a different type from the gas in the vacuum chamber.

[0008] Preferably, the release film body comprises a silicone oil coating, a PVC layer, a PET layer, a PE adhesive layer and a fluoride ion layer, and the silicone oil coating, the PVC layer, the PET layer, the PE adhesive layer and the fluoride ion layer are arranged in sequence from outside to inside and are fixed by heat pressing.

[0009] Preferably, the silicone oil coating is the outermost layer and is in direct contact with the air, and the fluoride ion layer is the innermost layer and is in direct contact with the antistatic layer.

[0010] Preferably, the peeling weight of the heavy-duty backing paper is between 5 and 10 grams, and the thickness of the heavy-duty backing paper is ten times the thickness of the release film body.

[0011] Preferably, the thickness of the edge-sealing paper is one fifth of the thickness of the release film body, and the edge-sealing paper is nanopaper.

[0012] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0013] 1. The utility model opens vacuum chambers at each edge of the release film body, and the gas injected into the vacuum chambers is different from the gas in the bubbles. The vacuum chambers contain inert gas, while the bubbles contain air. This facilitates the rapid and full mixing of the two gases during tearing and peeling, so that the pressure inside the release film body is greater than that outside, forming a pressure difference, and the edge paper is squeezed and lifted;

[0014] 2. After the edge sealing paper is broken and lifted up, the release film body can be easily peeled off from the base paper. At the same time, the anti-static layer arranged between the base paper and the release film body can help to peel it off quickly. The multi-layer plastic structure inside the release film body makes the internal structure of the entire release film body more stable and the entire appearance more upright, ensuring the one-time peeling of the release film body and the base paper.

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] The utility model provides Figure 1-3 The release film shown is an easy-to-tear release film, comprising a heavy-duty base paper 1, an anti-static layer 101, a release film body 2 and a vacuum chamber 3. The heavy-duty base paper 1 is tightly attached to the release film body 2 through the anti-static layer 101. Vacuum chambers 3 are provided at each corner of the release film body 2. Bubbles 4 are injected into the vacuum chambers 3. The vacuum chambers 3, bubbles 4 and the sides of the release film body 2 are wrapped with edge sealing paper 5.

[0024] A plurality of vacuum chambers 3 are provided at the edge of the release film body 2 to isolate the release film body 2 from the outside air by utilizing the excess gas. When needed, gas pressure can be formed to make it easier to peel the release film body 2 from the heavy base paper 1.

[0025] The vacuum chamber 3 is filled with inert gas, and the gas in the bubbles 4 is of a different type from that in the vacuum chamber 3 .

[0026] The different gases in the vacuum chamber 3 and the bubble 4 can facilitate rapid fusion of the bubble 4 after being squeezed out, so that the gas pressure inside the release film body 2 is greater than the gas pressure outside, making it easier to break the 5.

[0027] The release film body 2 includes a silicone oil coating 201, a PVC layer 202, a PET layer 203, a PE glue layer 204 and a fluoride ion layer 205. The silicone oil coating 201, the PVC layer 202, the PET layer 203, the PE glue layer 204 and the fluoride ion layer 205 are arranged in sequence from the outside to the inside and are fixed by heat pressing. The silicone oil coating 201 is the outermost layer and is in direct contact with the air. The fluoride ion layer 205 is the innermost layer and is in direct contact with the anti-static layer 101.

[0028] The interior of the entire release film body 2 has a mixed multi-layer structure, which can enhance the stability of the internal shape of the release film body 2 and facilitate overall peeling.

[0029] The peeling weight of the heavy-duty backing paper 1 is between 5 and 10 grams, and the thickness of the heavy-duty backing paper 1 is ten times the thickness of the release film body 2 .

[0030] The heavy-duty backing paper 1 has a heavier grammage, and it is easier to peel the release film body 2 from the heavy-duty backing paper 1 , while the heavy-duty backing paper 1 is not affected.

[0031] The thickness of the edge sealing paper 5 is one fifth of the thickness of the release film body 2 , and the edge sealing paper 5 is nano paper.

[0032] The edge-sealing paper 5 is nano-paper, so its structure is thinner and softer, and it is easier to be squeezed.

[0033] Working principle of this utility model:

[0034] Refer to the instruction manual Figure 1-3 When using the utility model, firstly, the antistatic layer 101 arranged between the heavy-duty base paper 1 and the release film body 2 can make it easier to peel the release film body 2 from the heavy-duty base paper 1, and, because of the gram weight of the heavy-duty base paper 1, it is easier to peel the release film body 2;

[0035] Refer to the instruction manual Figure 3-5 When the utility model is used, the combination of silicon and fluorine elements of the silicone oil coating 201 and the fluorine ion layer 205 weakens the adhesion of the adhesive between the heavy-duty backing paper 1 and the release film body 2, making it easier to peel off. At the same time, the mixed plastic material of the PVC layer 202, the PET layer 203 and the PE adhesive layer 204 can enhance the hardness of the entire release film body 2, and make the appearance more stiff.

[0036] When peeling is required, push any bubble 4 toward the edge and press it hard to break it. The gas inside it will combine with the gas in the vacuum chamber 3 to form a pressure difference with the outside air, that is, pressure will be formed, which can break the edge paper 5. The edge of the broken edge paper 5 will be lifted up, and the edge paper 5 and the heavy base paper 1 can be easily peeled off from the heavy base paper 1.
