Description

Technical Field

[0001] This utility model relates to the field of label technology, specifically to a multi-layer self-adhesive label. Background Technology

[0002] In the field of modern product labeling and packaging, multi-layer self-adhesive labels have been widely used due to their advantages such as being able to carry rich information and achieve unique designs. Traditional multi-layer self-adhesive labels usually consist of a top layer, a printing layer, a middle layer, and a bottom layer with a base adhesive. However, in the actual storage and circulation process, a prominent problem has gradually emerged.

[0003] Due to limitations in label structure design and packaging protection, the periphery of the adhesive base is easily exposed to air. Air contains oxygen, moisture, dust particles, and various impurities. When stored for a long time, oxygen slowly oxidizes the organic components in the adhesive base, altering its chemical structure and reducing its adhesion. Moisture intrusion can cause the adhesive base to become damp and deteriorate, affecting the uniformity of its adhesion. Dust and other impurities, once adhering to the surface of the adhesive base, will hinder the close adhesion between the adhesive base and the object being applied. The combined effect of these factors severely affects the adhesion of the adhesive base, causing problems such as label detachment and peeling during application. Therefore, there is an urgent need for a multi-layer self-adhesive label to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a multi-layer self-adhesive label to solve the problem mentioned in the background art that the base adhesive of traditional multi-layer self-adhesive labels is easily exposed to air, which may affect the adhesion of the base adhesive after a long storage period.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer self-adhesive label, comprising a main body paper, an adhesive paper on the bottom surface of the main body paper, a backing paper fixedly connected to the bottom surface of the adhesive paper, a shielding groove on the top surface of the backing paper, an embedding groove on the bottom surface of the main body paper, a fixed connection between the top surface of the backing paper and the inner wall of the embedding groove, and the size of the backing paper matching the size of the main body paper.

[0006] Preferably, an isolation layer is fixedly connected to the bottom surface of the main body paper, and the bottom surface of the isolation layer is fixedly connected to the top surface of the coated paper. The isolation layer is made of glassine paper.

[0007] Preferably, the bottom surface of the adhesive paper has an adhesive groove, and the bottom surface of the adhesive paper is in contact with the inner wall of the shielding groove.

[0008] Preferably, the circumferential side of the base paper is provided with a clearance groove, the size of which matches the size of the embedding groove.

[0009] Preferably, both the periphery of the main paper and the periphery of the base paper are provided with arc edges, and the dimensions of the multiple arc edges are matched.

[0010] Preferably, the dimensions of the adhesive paper and the isolation layer are matched with the dimensions of the shielding groove, and the adhesive paper and the isolation layer are both disposed on the inner wall of the shielding groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By using the main body paper, adhesive paper, adhesive tank, backing paper, and embedding groove in a coordinated manner, the bottom surface of the adhesive paper is in contact with the inner wall of the shielding groove, thus forming a sealed space inside the adhesive tank. This reduces the probability of the adhesive inside the adhesive tank coming into contact with the outside air. At the same time, the bottom surface of the main body paper has an embedding groove, and the top surface of the backing paper is in contact with the inner wall of the embedding groove, further preventing the adhesive inside the adhesive tank from coming into rapid contact with the outside air, thereby improving the stability of the self-adhesive label's adhesion.

[0021] 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.

[0022] Please see Figure 1-7 This utility model provides a multi-layer self-adhesive label, including a main body paper 1, an adhesive paper 2 on the bottom surface of the main body paper 1, a backing paper 3 fixedly connected to the bottom surface of the adhesive paper 2, a shielding groove 4 on the top surface of the backing paper 3, an embedding groove 5 on the bottom surface of the main body paper 1, and a fixed connection between the top surface of the backing paper 3 and the inner wall of the embedding groove 5. The size of the backing paper 3 matches the size of the main body paper 1. By using the adhesive paper 2, the shielding groove 4, the backing paper 3, and the embedding groove 5 in cooperation, the bottom surface of the adhesive paper 2 is in contact with the inner wall of the shielding groove 4, and the top surface of the backing paper 3 is in contact with the inner wall of the embedding groove 5, thereby reducing the probability of the adhesive on the bottom surface of the adhesive paper 2 coming into rapid contact with the outside air and improving the stability of the self-adhesive label's adhesion.

[0023] Furthermore, an isolation layer 6 is fixedly connected to the bottom surface of the main body paper 1. The bottom surface of the isolation layer 6 is fixedly connected to the top surface of the adhesive paper 2. The isolation layer 6 is made of cellophane. The cellophane isolation layer 6 facilitates sufficient isolation of oxygen and water vapor, thereby effectively preventing the influence of external environmental factors on the adhesive and reducing the possibility of deterioration or performance degradation of the adhesive due to contact with air, moisture, etc.

[0024] Furthermore, the bottom surface of the adhesive paper 2 is provided with an adhesive groove 7, and the bottom surface of the adhesive paper 2 is attached to the inner wall of the shielding groove 4. By setting the bottom surface of the adhesive paper 2 to be attached to the inner wall of the shielding groove 4, the probability of the adhesive inside the adhesive groove 7 coming into contact with the air is avoided.

[0025] Furthermore, a clearance groove 8 is provided on the periphery of the bottom paper 3. The size of the clearance groove 8 matches the size of the embedding groove 5. The clearance groove 8 provided on the periphery of the bottom paper 3 makes it easy to quickly tear off the bottom paper 3 during use, thus improving work efficiency.

[0026] Furthermore, both the periphery of the main body paper 1 and the periphery of the bottom paper 3 are provided with arc edges 9. The multiple arc edges 9 are matched in size. The arc edges 9 are designed to prevent the adhesive on the thinner main body paper 1 and bottom paper 3 from accidentally scratching the workers.

[0027] Furthermore, the dimensions of the adhesive paper 2 and the isolation layer 6 are both matched with the dimensions of the shielding groove 4. The adhesive paper 2 and the isolation layer 6 are both set on the inner wall of the shielding groove 4. By setting the dimensions of the adhesive paper 2 and the isolation layer 6 to match the dimensions of the shielding groove 4, it is easy to fully isolate the adhesive paper 2 and the isolation layer 6.

[0028] Working principle: The main body paper 1, adhesive paper 2, adhesive trough 7, backing paper 3, and embedding groove 5 work together to fill the inside of the adhesive trough 7 with adhesive material. The bottom surface of the adhesive paper 2 is in contact with the inner wall of the shielding groove 4, thus forming a sealed space inside the adhesive trough 7. This reduces the probability of the adhesive inside the adhesive trough 7 coming into contact with the outside air. At the same time, the bottom surface of the main body paper 1 has an embedding groove 5, and the top surface of the backing paper 3 is in contact with the inner wall of the embedding groove 5, further preventing the adhesive inside the adhesive trough 7 from coming into rapid contact with the outside air, thereby improving the stability of the self-adhesive label's adhesion.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
