Description

Technical Field

[0001] This utility model relates to the field of paper product technology, and more specifically, to an easy-to-stick self-adhesive paper. Background Technology

[0002] Self-adhesive paper is a self-adhesive composite paper product widely used in industry and daily life due to its ease of use. The paper layers of self-adhesive paper are printed with patterns and markings, while the film layer protects the adhesive layer. To use it, the film layer is first peeled off, and then the self-adhesive paper is pasted onto the object through the adhesive layer. In actual use, it has been found that because the adhesive layer is very strong, peeling off the film layer at the corners is difficult (the film layer is always peeled off starting from the corners, hence the name "corner peeling operation"), easily damaging the edges and corners of the self-adhesive paper. Furthermore, because the paper layers are relatively thin and the paper's stiffness is poor, the paper surface is prone to twisting and wrinkling during the pasting process, affecting the quality of the paste. These problems all affect the user experience of self-adhesive paper and urgently require design improvements. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an easy-to-apply self-adhesive paper. This invention has a tear-off auxiliary structure designed at the edges and corners of the paper surface. It uses a self-heating effect to soften the adhesive layer in a short time, making the edge and corner film layer easy to peel off quickly. This invention also has reinforcing lines composited inside the paper layer to enhance the paper's stiffness, so that the paper can remain straight during the pasting process and is easy to paste.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An easy-to-apply self-adhesive paper includes a first paper layer, a second paper layer, an adhesive layer, and a film layer. The first paper layer, the second paper layer, the adhesive layer, and the film layer are sequentially laminated and connected from top to bottom. Pattern information is printed on the surface of the first paper layer. Several reinforcing lines are laminated and installed between the first paper layer and the second paper layer. A tear-off auxiliary structure is provided at the corner of the first paper layer, which can soften the adhesive layer at the corresponding position.

[0006] Furthermore, a plurality of grooves are formed on the contact surface between the second paper layer and the first paper layer, and a reinforcing line is filled in each groove, with the plurality of reinforcing lines arranged in parallel.

[0007] Furthermore, the reinforcing wire is made of glass fiber material.

[0008] Furthermore, arrow markings are printed on the surface of the first paper layer, and the direction of the arrow markings corresponds to the length direction of the reinforcing line.

[0009] Furthermore, a tear-off assist structure is provided at one corner of the first paper layer, and the number of tear-off assist structures provided on the first paper layer is not less than two.

[0010] Furthermore, the film-tearing auxiliary structure includes a groove, a self-heating material, and a sealing paper. The groove is located at the corner of the first paper layer. The self-heating material is filled in the groove. The sealing paper is pasted onto the surface of the first paper layer and can seal the groove.

[0011] Furthermore, the self-heating material is a chemical material that can generate heat upon contact with air.

[0012] The beneficial effects of this utility model are:

[0013] This invention features a tear-off aid structure at the edges and corners of the paper. The tear-off aid structure includes a chemical material that heats up upon contact with air, which softens the adhesive layer in a short time through a self-heating effect, making the edge and corner adhesive layer easy and quick to peel off. This invention also incorporates reinforcing lines within the paper layer to enhance the paper's stiffness, allowing the paper to remain straight during the pasting process and making it easy to paste.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1 and Figure 2The illustrated easy-to-apply self-adhesive paper includes a first paper layer 1, a second paper layer 2, an adhesive layer 3, and a film layer 4. These layers are sequentially bonded together from top to bottom. The first paper layer 1 has printed patterns on its surface. The adhesive layer 3 is used to create the adhesive effect, and the film layer 4 protects the adhesive layer 3. Before use, the film layer 4 must be peeled off. Commonly used self-adhesive paper products have thin paper layers and poor paper stiffness, making them prone to twisting and wrinkling during application, affecting the appearance quality. Therefore, this invention designs a double-layer structure and laminates the first paper layer 1 with the second paper layer 2. Several reinforcing lines 6 enhance the paper's strength, significantly improving its stiffness. During pasting, the paper hangs naturally, and after pasting, it is less prone to twisting or wrinkling, greatly improving the user's bonding experience. However, due to the use of a high-viscosity adhesive layer 3, users have reported difficulties in peeling off the film layer 4. Sometimes, forcibly peeling it off multiple times can damage the paper surface, causing it to be unusable. Based on user feedback, this utility model specifically designs a film-peeling auxiliary structure 5 at the corner of the first paper layer 1. The film-peeling auxiliary structure 5 softens the adhesive layer 3 at the corresponding position, facilitating the initial film peeling operation at the corner.

[0019] like Figure 1 As shown, several grooves 21 are formed on the contact surface between the second paper layer 2 and the first paper layer 1. Each groove 21 is filled with a reinforcing wire 6. The reinforcing wires 6 are arranged in parallel and evenly distributed. The reinforcing wires 6 are made of glass fiber material, which is lightweight and strong. The reinforcing wires 6 do not affect the overall weight of the paper after lamination, but can effectively ensure the straightness of the paper. When using the self-adhesive paper product of this invention, it is best to stick it with the reinforcing wires 6 hanging downwards. This method yields better results, and even beginners can achieve good adhesion. Figure 2 As shown, an arrow mark 11 is printed on the surface of the first paper layer 1. The direction of the arrow mark 11 corresponds to the length direction of the reinforcing line 6. The arrow mark 11 can help users determine the direction of the reinforcing line 6, so that users can use this utility model accurately.

[0020] like Figure 2 As shown, the present invention is generally a rectangular paper with four corners. The film peeling operation generally only needs to be performed on one corner. Therefore, the present invention has a film peeling auxiliary structure 5 at least at one corner. Considering the problem of accidental failure, the number of film peeling auxiliary structures 5 on the first paper layer 1 is not less than two, that is, two corners. The present invention will only have one film peeling auxiliary structure 5 at each corner of the first paper layer 1.

[0021] like Figure 1As shown, the film-peeling auxiliary structure 5 includes a groove 51, a self-heating material 52, and a sealing paper 53. The groove 51 is located at the corner of the first paper layer 1. During factory production, the self-heating material 52 is filled into the groove 51, and then the sealing paper 53 is pasted onto the surface of the first paper layer 1. The sealing paper 53 can seal the groove 51, isolate and protect the self-heating material 52, preventing it from leaking out and contacting the outside air. The self-heating material 52 is a chemical material that can generate heat upon contact with air. When using this invention, the sealing paper 53 is first peeled off, and the self-heating material 52 comes into contact with the air and generates heat. The chemical reaction generates heat that is transferred to the adhesive layer 3, softening the adhesive. Then, peeling off the film layer 4 becomes much easier. In this invention, the self-heating material 52 only softens the adhesive layer 3 and does not ignite the paper. Furthermore, the self-heating material 52 reacts quickly. Therefore, after removing the sealing paper 53, the film layer 4 should be peeled off immediately. Because the adhesive layer 3 softens quickly and then naturally cures, it does not affect the quality of the corner bonding. After the above design of this invention is applied, users generally report that peeling off the film becomes very convenient.

[0022] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
