Description

Technical Field

[0001] This utility model relates to the field of label technology, and in particular to a waterproof label for machine heads. Background Technology

[0002] Everyday labels (often called "self-adhesive labels") are a type of identification material that allows for quick application through adhesive backing. They are widely used in product labeling, document classification, logistics identification, and other scenarios. For example, labels on some equipment heads typically indicate the equipment's model and basic parameters.

[0003] A label typically consists of a top layer, an adhesive layer, and a backing paper. The top layer carries text, images, barcodes, and other information; it is the directly visible surface layer. The adhesive layer allows the label to adhere to various surfaces. The backing paper protects the adhesive layer, preventing the label from sticking together before use and allowing it to be peeled off during application.

[0004] In existing technologies, the surface layer of labels typically has the following structures: First, it uses non-waterproof paper such as handwriting paper. This type of paper allows the label content to be clearly displayed, making it easy for users to view. However, due to its poor water resistance, it is prone to wrinkling and damage when exposed to water. Second, it uses a waterproof film on which the desired content is processed. This type of paper is basically unaffected by water, but it is mostly transparent, which affects readability when the color of the object being labeled is complex, making it difficult for users to view. Third, it covers the surface of handwriting paper with a transparent film, thereby improving the water resistance of the handwriting paper while ensuring that the readability of the label is not affected. However, this design still has drawbacks. Although covering only the surface can block water from the surface, when water (or oil) flows from the side, water stains will slowly seep into the inner handwriting paper, thus affecting the clarity of the content on the handwriting paper.

[0005] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a waterproof label for machine heads, comprising a surface layer, a first adhesive layer disposed on the adhesive surface of the surface layer, and a backing paper disposed on the first adhesive layer;

[0008] The surface layer includes a content paper and an upper waterproof film and a lower waterproof film that wrap the content paper, with a portion of the edges of the upper waterproof film and the lower waterproof film exposed outside the content paper and bonded to each other;

[0009] The first adhesive layer is disposed on the lower waterproof film and is used to bond and fix it to the surface of the item.

[0010] As a further embodiment of this utility model, the edges of the upper waterproof film and the lower waterproof film are welded together by a heat sealing process.

[0011] As a further embodiment of this utility model: a second adhesive layer is provided on both sides of the upper waterproof film and the lower waterproof film, and the second adhesive layer is bonded to the inner paper.

[0012] As a further embodiment of this invention: the content paper is provided with a fiber mesh inside.

[0013] As a further embodiment of this utility model: the contact surface between the lower waterproof film and the first adhesive layer is die-cut with serrated patterns, and the first adhesive layer is embedded in the gaps of the serrated patterns to form a mechanical anchor.

[0014] As a further embodiment of this utility model: a water-blocking adhesive ring is provided around the edge of the lower waterproof film, the water-blocking adhesive ring is embedded in the first adhesive layer, and a certain gap is left between the lower end of the water-blocking adhesive ring and the bottom side of the first adhesive layer.

[0015] As a further embodiment of this utility model: both the upper waterproof film and the lower waterproof film are PET films.

[0016] Compared with the existing technology, the beneficial effects of this technical solution are as follows: When in use, the bottom paper is peeled off, and then the label is pasted on the surface of the item using the first adhesive layer. The content of the label is clearly presented on the content paper on the surface layer. The content paper is fully wrapped and sealed by the upper and lower waterproof films, thereby forming an all-round waterproof sealing effect. The transparent upper and lower waterproof films ensure that the clarity of the content on the content paper is not affected.

[0017] In summary, this label achieves a comprehensive waterproof seal through transparent upper and lower waterproof films, preventing the inner content paper from coming into contact with water, thus solving the problem of water seepage. This also prevents the text on the content paper from being affected and avoids the content paper from becoming soft and mushy, thereby extending the label's lifespan and solving the problem of poor readability of the label content in humid environments.

[0018] Furthermore, the content paper is made of ordinary paper, coated paper, writing paper, etc., which will result in better content display. The combination of transparent upper and lower waterproof films for full wrapping can solve the problem of softening and tearing when exposed to water, thereby greatly improving the clarity of the label content.

[0019] During the process of attaching the label to the surface of the item, a certain pressure is applied to make the water-blocking adhesive ring penetrate the first adhesive layer and adhere tightly to the surface of the item. After penetrating the first adhesive layer, the water-blocking adhesive ring forms a waterproof sealing ring, which prevents water from penetrating along the edge into the entire first adhesive layer. This avoids the first adhesive layer from being weakened by water stains over a long period of time, which would cause the adhesive strength to weaken and the material to age, thereby preventing the label from falling off.

[0020] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0027] 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.

[0028] Please see Figure 1-3 A waterproof label for machine heads includes a surface layer 1, a first adhesive layer 2 disposed on the adhesive surface of the surface layer 1, and a backing paper 3 disposed on the first adhesive layer 2;

[0029] The surface layer 1 includes a content paper 4 and an upper waterproof film 5 and a lower waterproof film 6 that wrap the content paper 4, and a portion of the edges of the upper waterproof film 5 and the lower waterproof film 6 are exposed outside the content paper 4 and are bonded to each other.

[0030] The first adhesive layer 2 is disposed on the lower waterproof film 6 and is used to bond and fix it to the surface of the item.

[0031] Specifically, in use, the bottom paper 3 is peeled off from the first adhesive layer 2, and then the label is attached to the surface of the item using the first adhesive layer 2. The content of the label is clearly displayed on the content paper 4 of the surface layer 1, and the content paper 4 is fully wrapped and sealed by the upper waterproof film 5 and the lower waterproof film 6, thereby forming an all-round waterproof sealing effect. The transparent upper waterproof film 5 and the lower waterproof film 6 ensure that the clarity of the content on the content paper 4 is not affected.

[0032] In summary, this label is fully enclosed by a transparent upper waterproof film 5 and a lower waterproof film 6, forming an all-round waterproof sealing effect. This prevents the inner content paper 4 from coming into contact with water, solving the problem of water seepage. This also prevents the text on the content paper 4 from being affected and prevents the content paper 4 from becoming soft and mushy, thereby increasing the label's service life and solving the problem of poor readability of the label content in humid environments.

[0033] Furthermore, the content paper 4 is made of ordinary paper such as coated paper or writing paper, which will result in better content display. The combination of transparent upper waterproof film 5 and lower waterproof film 6 for full wrapping can solve the problem of it becoming soft and rotten when exposed to water, thereby greatly improving the clarity of the label content.

[0034] Both the upper waterproof film 5 and the lower waterproof film 6 are PET films. PET films have high light transmittance, ensuring that the text and patterns on the content paper 4 are displayed clearly and without distortion.

[0035] In some embodiments, the edges of the upper waterproof membrane 5 and the lower waterproof membrane 6 are welded together using a heat-sealing process.

[0036] Specifically, the upper waterproof membrane 5 can be hot-pressed, and the temperature of the hot pressing can be reasonably controlled to fuse the upper waterproof membrane 5 with the lower waterproof membrane 6, thereby sealing the upper waterproof membrane 5 and the lower waterproof membrane 6, preventing water stains from slowly seeping in from the contact gap, and further improving the overall waterproof performance.

[0037] In another embodiment, a second adhesive layer 7 is provided on both sides of the upper waterproof film 5 and the lower waterproof film 6, and the second adhesive layer 7 is bonded to the inner paper 4.

[0038] Specifically, the second adhesive layer 7 can be made of waterproof adhesive, which ensures waterproof sealing while bonding and fixing the upper waterproof film 5 and the lower waterproof film 6 together. The second adhesive layer 7 on both the upper waterproof film 5 and the lower waterproof film 6 is bonded to the content paper 4, which can improve the positional stability of the content paper 4 between the upper waterproof film 5 and the lower waterproof film 6. This prevents the content paper 4 from being displaced or wrinkled when squeezed or pushed during daily use, thus avoiding affecting the presentation of the content.

[0039] In some embodiments, the content paper 4 is provided with a fiber mesh 8 inside.

[0040] Specifically, adding fiber mesh 8 to the content paper 4 can improve the longitudinal and transverse tear strength of the content paper 4, significantly improving the tear resistance of the content paper 4; at the same time, it can improve the toughness of the content paper 4, optimize the folding endurance and wrinkle resistance, and reduce the occurrence of cracking and wrinkling when the content paper 4 is bent or squeezed.

[0041] In some embodiments, the contact surface between the lower waterproof membrane 6 and the first adhesive layer 2 is die-cut with serrated patterns 9, and the first adhesive layer 2 is embedded in the gaps of the serrated patterns 9 to form a mechanical anchor.

[0042] Specifically, when the waterproof film 6 is adhered to the surface of the item through the first adhesive layer 2, the first adhesive layer 2 is squeezed and fills the gaps of the serrations 9, so that the first adhesive layer 2 and the gaps of the serrations 9 form a physical fit. When the label is subjected to edge peeling force, the gaps of the serrations 9 generate lateral resistance to the first adhesive layer 2 and disperse the peeling stress to multiple serrated anchor points, thereby preventing the edge adhesive layer from separating from the substrate and enhancing the bonding reliability.

[0043] In some embodiments, a water-blocking adhesive ring 10 is provided around the edge of the lower waterproof membrane 6. The water-blocking adhesive ring 10 is embedded in the first adhesive layer 2, and a certain gap is left between the lower end of the water-blocking adhesive ring 10 and the bottom side of the first adhesive layer 2.

[0044] During the process of attaching the label to the surface of the item, by applying a certain pressure, the water-blocking adhesive ring 10 penetrates the first adhesive layer 2 and adheres tightly to the surface of the item. At the same time, the pressure compresses the first adhesive layer 2 and adheres tightly to the surface of the item. After penetrating the first adhesive layer 2, the water-blocking adhesive ring 10 forms a waterproof sealing ring, which prevents water from penetrating along the edge into the entire first adhesive layer 2, thus preventing the first adhesive layer 2 from being weakened by water stains over a long period of time, and thus preventing the label from falling off.

[0045] Among them, the water-blocking rubber ring 10 is made of a material with high elasticity, low water absorption and strong weather resistance, such as silicone rubber.

[0046] 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. No reference numerals in the claims should be construed as limiting the scope of the claims.
