[0002] With the continuous development of various products and packaging demand, the waterproof performance of not dry adhesive label in the market is put forward higher requirement. Especially in outdoor environment or bad weather conditions, the traditional not dry adhesive label often cannot effectively cope with rain, moisture, ice and snow and other external factors erosion, therefore, it is urgent to improve its waterproof performance.

[0003] In the prior art, multi-layer waterproof film material is generally used for film processing of not dry adhesive label to improve the overall waterproofness of the label. These multi-layer film materials are usually composed of high-density polyethylene (HDPE), polypropylene (PP) and other synthetic materials, which have good waterproof isolation performance. However, this technology mainly focuses on the surface and front protection of the label, and lacks effective protection measures for the side edge of the label. As a relatively weak part, the side edge of the label is easily eroded by moisture.

[0004] In addition, the multi-layer film material often shows certain brittleness when subjected to external impact or strong rain washing. Due to the complex adhesion between the hierarchical structure and different materials of the label, when the external pressure is too large, the edge of the label may be torn, causing the interlayer material to fall off, further affecting the waterproofness and overall durability of the label. Especially in high humidity, wet environment, this falling problem is more serious, which may cause the label to fail, thereby affecting the accurate transmission of information on the label and the protection of brand image.

[0005] Therefore, although the prior art can improve the waterproofness of the label to some extent, due to the insufficient protection measures for the side edge and overall structure of the label, there are still problems such as tearing and falling, which cannot meet the use requirements in long-term and extreme environment.

[0029] Embodiment 1:

[0030] As shown in Figures 1-3 , the present embodiment provides a waterproof adhesive label, comprising:

[0031] A hard paper roll 1;

[0032] A label roll 2 is wound around the outside of the hard paper roll 1;

[0033] A label body 3 is provided on the label roll 2, and the label body 3 is provided at equal intervals along the length direction of the label roll 2;

[0034] Each label body 3 includes a base layer 31 provided on the label roll 2, a bottom of the base layer 31 is provided with a pressure-sensitive adhesive layer 32, a top of the base layer 31 is provided with a fireproof layer 33, a top of the fireproof layer 33 is provided with a wear-resistant layer 34, a top of the wear-resistant layer 34 is provided with a waterproof coating layer 35, a top of the waterproof coating layer 35 is provided with a hydrophobic layer 36, and a top of the hydrophobic layer 36 is provided with a coating layer 37;

[0035] An outer waterproof layer 4 is provided on the side edge of the label body 3, and the waterproof layer is located outside the label body 3 and wraps the base layer 31, the pressure-sensitive adhesive layer 32, the fireproof layer 33, the wear-resistant layer 34, the waterproof coating layer 35, the hydrophobic layer 36 and the coating layer 37, preventing tearing and peeling between the layers due to external environmental influences.

[0036] In the technical solution, the waterproof pressure-sensitive adhesive label is designed with multiple layers, especially the outer waterproof layer 4 on the side edge, which solves the problem of traditional label side edge being easily eroded by moisture, and can fully block the penetration of moisture, ensuring the integrity and clarity of the label information. The multiple layers of the label body 3 (including the fireproof layer 33, the wear-resistant layer 34, the hydrophobic layer 36, the coating layer 37, etc.) provide physical and chemical protection, so that the label can maintain strong structural stability and long service life in high humidity, high temperature or friction environment. Especially, the outer waterproof layer 4 can effectively prevent the label from tearing and peeling between layers due to external water flow impact. The top of the label is provided with a fireproof layer 33, which can effectively prevent the label from being damaged by fire in high temperature environment. The presence of the fireproof layer 33 enables the label to function in high temperature or near potential fire sources. In addition, the wear-resistant layer 34 provides additional mechanical protection to prevent the label from being damaged in high-frequency friction environment. Through the multiple design of the waterproof coating layer 35, the hydrophobic layer 36 and the coating layer 37, the label not only effectively resists water penetration, but also reduces the adhesion of stains and water droplets through the hydrophobic surface, making the label easier to clean and maintaining long-lasting beauty and use effect. The design of the label is suitable for various harsh environmental conditions, especially outdoor, humid, high temperature or strong ultraviolet light places, which can cope with extreme weather, humid climate, chemical corrosion and other challenges, ensuring the long-term stability and reliability of the label.

[0037] Workflow: First, select the appropriate base layer 31 material as the label's bottom foundation. The base layer 31 is usually composed of materials with high strength and certain elasticity (such as paper, polyester film or PVC material) to ensure the overall stability of the label. Then, apply the adhesive layer 32 on the bottom of the base layer 31, which can make the label tightly adhere to the surface of the object, ensuring the pasting effect of the label. Next, the fireproof layer 33, wear-resistant layer 34, waterproof coating 35, hydrophobic layer 36 and covering layer 37 are coated or sprayed on the surface of the base layer 31 in turn. Each layer of material has a specific function: the fireproof layer 33 uses special fireproof paint or synthetic materials to prevent the label from burning or being damaged when exposed to high temperatures or near fire sources. The wear-resistant layer 34 is usually made of materials with strong wear resistance (such as polyurethane coating) to enhance the label's resistance to friction and extend its service life. The waterproof coating 35 mainly uses waterproof paint or film to help prevent water from penetrating into the label, maintaining the label's waterproof function. The hydrophobic layer 36 has a high hydrophobic surface that allows water droplets to slide off, reducing water contact with the label surface and preventing stains or water marks from adhering. The last layer, the covering layer 37, is the most protective layer, effectively preventing physical impact, scratches and chemical erosion. In the side edge area of the label, special equipment is used to completely wrap the outer waterproof layer 4 around the edges of the label through heat sealing or adhesive processes, ensuring that every side of the label is tightly protected. This design effectively prevents external moisture from penetrating into the label through the edges, protecting the label's layers from water damage. After completing all the coating and packaging processes, the labels are rolled according to the specified specifications and requirements, and wound around the hard paper reel 1. Each label body 3 is evenly spaced to facilitate subsequent splitting and use. Finally, the label roll 2 is packaged and ready to be delivered to the customer or application site. In actual use, the label is firmly attached to the surface of the object through the adhesive layer 32. When the label is exposed to outdoor environments, the waterproof coating 35, hydrophobic layer 36 and wear-resistant layer 34 can effectively resist the erosion of external factors such as rain, UV rays and stains, ensuring the clarity of the label information and preventing damage caused by external environmental factors. Due to the presence of the hydrophobic layer 36, water droplets can quickly slide off the label after exposure to rain or humid environments, without leaving water stains or stains on the label surface. In addition, the wear-resistant layer 34 can also prevent the label from being damaged by friction during daily use, extending the label's service life and making it suitable for long-term use in high-friction and harsh environments.

[0038] As Figure 3 shown in the present embodiment, the optimized outer waterproof layer 4 is provided with a sealing layer 5 between the label body 3.

[0039] In the technical solution, the sealing layer 5 is arranged between the outer waterproof layer 4 and the label body 3, which can effectively seal the gaps between the layers of the label and prevent moisture, dust and other substances from entering the inside of the label through possible gaps. The addition of the sealing layer 5 not only enhances the waterproofness of the label, but also effectively avoids the problem of moisture penetration caused by poor contact between the outer waterproof layer 4 and the inner layer of the traditional label, thereby improving the overall protection effect of the label. The presence of the sealing layer 5 can enhance the bonding force between the outer waterproof layer 4 and the label body 3, making the label more secure under external impact and tension, and reducing the risk of tearing caused by heavy rain, wind or friction. The sealing layer 5 provides additional physical bonding, allowing the multiple layers of the label body 3 to be tightly combined, reducing the likelihood of separation between the layers of the label material due to external forces. The sealing layer 5 not only acts as a physical barrier, but also provides some chemical protection. Especially when the label needs to be exposed to oil stains, acid and alkali substances or other chemically corrosive environments, the presence of the sealing layer 5 can effectively prevent these substances from penetrating into the inside of the label, ensuring the stability and durability of the label. The addition of the sealing layer 5 makes the structure of the label more complete and strong, increasing the overall strength and durability, especially in harsh environments, which can effectively prevent the label from being damaged due to friction, collision or other external forces, further improving the compression resistance of the label.

[0040] In actual application, the label is pasted to the surface of the article through the adhesive layer 32. The sealing layer 5, the outer waterproof layer 4 and other protective layers effectively isolate the external moisture, dust, chemical substances and external forces, ensuring the reliability and durability of the label information during long-term use. During long-term use, the design of the sealing layer 5 and the outer waterproof layer 4 ensures that the label can continuously resist the influence of harsh environments. Whether it is heavy rain, humidity, friction or chemical corrosion, the label can remain clear and intact, greatly extending the service life of the label and ensuring that the label information will not be distorted or disappear due to changes in the external environment.

[0041] Embodiment 2:

[0042] The embodiment provides a waterproof adhesive label, in addition to the technical solutions of the above embodiments, further having the following technical features.

[0043] As shown in Figure 2 In this embodiment, the optimized waterproof coating 35 is made of high-chlorinated polyethylene coating.

[0044] In the technical solution, the high-chlorinated polyethylene coating provides enhanced waterproofness and weather resistance to meet the requirements for long-term stability of the label in some special environments (such as humidity, rain, strong ultraviolet light, etc.). Generally, when a label is used in an external environment, if no waterproof treatment is taken, it is easy to be eroded by moisture or to have blurred printing, reduced adhesion, or damage due to a humid environment. By using the high-chlorinated polyethylene coating, the label can effectively prevent moisture penetration and maintain stability and readability for a long time. The waterproof adhesive label with the high-chlorinated polyethylene coating not only provides excellent waterproof performance but also has excellent weather resistance, chemical resistance, and high adhesion, suitable for various harsh environmental conditions. Through the process flow of coating, curing, printing, and post-processing, a high-quality label can be made, and its stable performance can be ensured during long-term use.

[0045] As shown in Figure 2 In this embodiment, the optimized hydrophobic layer 36 is coated with a nano-hydrophobic material.

[0046] In the technical solution, the hydrophobic layer 36 coated on the surface of the label can effectively prevent water droplets and oil stains from adhering and prevent dirt from contaminating the label, while reducing the impact of water stains on the label information. The nano material has extremely small particle size, and its surface properties can further improve the hydrophobicity and maintain its excellent waterproofness and durability during long-term use. Therefore, the application of the nano-hydrophobic material coating can greatly improve the reliability and service life of the waterproof adhesive label. Thus, the waterproof adhesive label not only effectively prevents water but also resists the adhesion of pollutants such as oil stains and dust, and has strong self-cleaning ability.

[0047] As shown in Figure 2 In this embodiment, the optimized coating layer 37 is a PE transparent film.

[0048] In the technical solution, the coating layer 37 is a PE transparent film, which has excellent waterproof performance, so that the label can effectively prevent moisture from penetrating even in a humid environment, ensuring the durability and service life of the label. The selection of the PE transparent film makes the patterns or characters on the label clear and visible, maintaining the visual effect of the label. The transparent coating layer 37 does not affect the information content on the label, ensuring that consumers or users can easily read the printed information on the label, and has good gloss. The coating layer 37 as a protective film can effectively resist external factors such as oil stains, dust, scratches, etc., thereby prolonging the service life of the label and avoiding the loss of readability due to physical damage. By using the PE transparent film as the coating layer 37, the waterproof adhesive label not only provides waterproof protection but also maintains the clarity and durability of the label, is suitable for various surfaces, and has good weather resistance, environmental friendliness, and economy, and is widely used in the fields of commodity identification and logistics labeling.

[0049] Embodiment 3:

[0050] The embodiment provides a waterproof adhesive label, in addition to comprising the technical scheme of the above embodiment, further having the following technical features.

[0051] As Figure 2 shown, in the embodiment, the optimized self-luminous layer 6 is arranged between the top of the base layer 31 and the fireproof layer 33.

[0052] In the technical scheme, the self-luminous layer 6 endows the waterproof adhesive label with the ability to emit light by itself in the case of dark light or no external light source. This makes the label still visible in a low-light environment, facilitating identification and reading. The self-luminous layer 6 is usually made of materials containing luminous materials (such as fluorescent powder, phosphor materials, etc.), which can release visible light after absorbing certain energy. By adding the self-luminous layer 6, the visibility of the label is significantly improved, especially in dark or insufficient light environments. This is particularly important for application scenarios that require identification at night or in low-light environments (such as security labels, emergency indications, device identification, etc.). The self-luminous label can provide instant visual indication, increasing safety of use. The self-luminous layer 6 has an important function in emergency situations, such as fire safety identification or emergency evacuation indication. The label can still emit light continuously in the case of power failure or low light, helping people quickly locate important information and ensure safety.
