Abstract
Description
Technical Field
[0001] This utility model relates to the field of self-adhesive label technology, specifically to a waterproof self-adhesive label. Background Technology
[0002] In practical applications of traditional self-adhesive labels, especially in humid environments, contact with liquids, or high humidity scenarios, the problem of water seepage at the label edges has always been difficult to solve effectively. Conventional labels rely solely on a single waterproof membrane (2) or a simple adhesive layer design, which cannot effectively protect the label's side cut surfaces and weak edge areas. Liquids can easily seep in from the label edges, causing the label content to become blurred, the adhesive layer to fail, or even the entire label to fall off, seriously affecting the label's lifespan and information recognition function. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a waterproof self-adhesive label.
[0004] The purpose of this utility model can be achieved through the following technical solution: a waterproof self-adhesive label, including a label body, a waterproof membrane on the label body, the waterproof membrane wrapping the cut surface of the side of the label body and extending outward to form an extension, an adhesive layer on the bottom of both the label body and the waterproof membrane, and a waterproof locking edge on the edge of the label body, which is a high-density area formed by compressing the edge material of the label body through a molding process.
[0005] Preferably, it also includes release paper, which is bonded to the label body and the extension by an adhesive layer.
[0006] Preferably, the waterproof membrane has a hydrophobic layer.
[0007] Preferably, a tear handle is provided on one side of the extension.
[0008] Preferably, the adhesive strength of the waterproof membrane layer is greater than that of the adhesive strength of the label body layer.
[0009] Preferably, the tear handle has an anti-slip layer.
[0010] The beneficial effects of this invention are as follows: By wrapping the label body and side cut surfaces with a waterproof membrane and extending it to form an extension, it acts like a sealed shell, constructing the first physical barrier that effectively prevents liquid from directly contacting the label body. The label body's edges are molded to form a high-density waterproof edge locking area, reducing the porosity of the edge material and minimizing water vapor penetration channels. These two elements work together to form a dual-protection system: the waterproof membrane intercepts external liquids, and the waterproof edge locking blocks moisture penetration paths, synergistically improving the waterproof performance of the label edges. This effectively prevents liquid from intruding from the edges, ensuring the label's integrity and functionality in humid environments. Attached Figure Description

[0016] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.
[0017] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
[0018] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0019] See Figures 1 to 3As shown, the structure of this utility model is as follows: a waterproof self-adhesive label includes a label body 1, a waterproof membrane 2 on the label body 1, the waterproof membrane 2 wrapping around the side cut surface of the label body 1 and extending outward to form an extension 3, an adhesive layer on the bottom of both the label body 1 and the waterproof membrane 2, and a waterproof locking edge 4 on the edge of the label body 1. The waterproof locking edge 4 is a high-density area formed by compressing the edge material of the label body 1 through a molding process. Specifically, the waterproof membrane 2, by wrapping around the side cut surface of the label and extending outward to form the extension 3, constructs the first physical barrier, tightly wrapping the label body 1 like a sealed shell, effectively preventing liquid from directly contacting the label body 1. At the same time, the high-density waterproof locking edge 4 structure is formed by compressing the edge material of the label body 1 through a molding process. This structure significantly reduces the porosity inside the label edge material, greatly reducing the water vapor penetration channels. The waterproof membrane 2 and the waterproof edge locking 4 work together to form a dual protection system: the waterproof membrane 2 intercepts external liquids, and the waterproof edge locking 4 blocks microscopic penetration paths. The two work together to greatly improve the waterproof performance of the label edge, effectively preventing liquids from penetrating from the label edge and ensuring that the label can maintain its integrity and functionality in a humid environment.
[0020] like Figure 1 , Figure 2 As shown, it also includes release paper 5, which is bonded to the label body 1 and the extension 3 by an adhesive layer. Specifically, the release paper 5 is used to support the label and provide temporary protection to prevent the adhesive layer from being contaminated with dust or foreign matter during storage or transportation, and to ensure the adhesiveness of the label when it is pasted. The surface of the release paper 5 has a silicone oil coating so that the adhesive layer can be easily peeled off without residue when the label body 1 is used.
[0021] Furthermore, a hydrophobic layer is provided on the waterproof membrane 2. Specifically, the hydrophobic layer can reduce the residence time of liquid on the waterproof membrane 2, reduce the probability of liquid penetration, and at the same time improve the self-cleaning ability of the label.
[0022] like Figure 1 , Figure 2 As shown, a tear handle 6 is provided on one side of the extension 3. Specifically, the tear handle 6 provides a clear and easy point of force when tearing off the label. By applying force with the tear handle 6, the waterproof film 2 and the label body 1 can be completely peeled off from the surface of the object being labeled, which greatly reduces the difficulty and time consumption of tearing off the label.
[0023] Furthermore, the adhesive strength of the waterproof membrane 2 layer is greater than that of the label body 1 layer. Specifically, the higher adhesive strength of the waterproof membrane 2 layer allows it to adhere tightly to the surface of the object being labeled, reducing gaps for liquid penetration and effectively enhancing the waterproof sealing of the label, ensuring stable operation even in humid environments. The lower adhesive strength of the label body 1 layer allows the user to easily remove the label body 1 from the object's surface by simply applying a pulling force to the waterproof membrane 2. This makes the operation convenient and smooth. At the same time, this difference in adhesive strength effectively avoids delamination and damage caused by excessive adhesive strength of the label body 1, as well as problems such as glue residue.
[0024] like Figure 3 As shown, the tearing handle 6 is provided with an anti-slip layer 7. Specifically, the anti-slip layer 7 increases the surface roughness or coefficient of friction of the tearing handle 6 to improve the friction between the fingers and the tearing handle 6 and prevent slipping.
[0025] In practical use, the waterproof membrane 2 and the label body 1 are firmly and tightly bonded to the object through an adhesive layer, ensuring the overall stability of the label. The waterproof membrane 2, through its extension 3 formed by wrapping around the side cut surfaces of the label, acts like a sealed shell, effectively preventing external liquids from directly contacting the label body 1, completing the first layer of protection. At the same time, the waterproof locking edge 4 formed by the molding process on the edge of the label body 1, with its high-density structure, reduces water vapor penetration channels, further blocking liquid intrusion paths at the microscopic level. The two work together to form a dual protection system, enabling the label to maintain its structural integrity and clear information even in harsh environments such as dampness, liquid splashes, or even immersion, thanks to its excellent waterproof performance, preventing the label from falling off or the content from becoming blurred due to liquid intrusion.
[0026] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
