Description

Technical Field

[0001] This utility model relates to the field of label sticker technology, and in particular to a multi-layer folded label sticker. Background Technology

[0002] In today's commodity circulation and labeling field, labels and stickers, as key carriers for conveying commodity information and identifying product characteristics, are widely used in various commodity packaging, documents and other scenarios. Traditional labels and stickers are mostly single-layer structures, which can only present fixed content in a limited space. With the globalization of commodities, the demand for diversified information, and the challenges of complex usage environments, their limitations have become increasingly prominent.

[0003] Faced with complex and ever-changing usage environments, conventional labels and stickers lack durability. In daily scenarios involving frequent touching and wiping, the surface of the stickers is easily scratched and worn, making key information blurry and difficult to read. For example, the text and images on the labels of daily chemical product bottles are often severely damaged due to repeated handling. When subjected to accidental pulling, the lack of tensile strength design makes them prone to breakage and damage, affecting the overall integrity. For instance, labels are torn due to external forces during logistics transportation. In humid, odorous, or oxygen-rich environments, moisture erosion, odor penetration, and oxidation reactions weaken the adhesive strength, change the material properties, and accelerate the aging and failure of the labels. For example, food packaging labels peel off after getting damp, and paper labels yellow and mold in high humidity environments. Furthermore, once traditional labels and stickers are fixed in place, it is difficult to restore their good adhesion after repeated opening and closing. Repeated opening and closing can also easily cause creases and breakage at the folds, shortening their lifespan and hindering long-term, efficient information exchange.

[0004] Therefore, it is necessary to provide a new multi-layered folded label sticker to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a multi-layer folded label sticker.

[0006] This utility model provides a multi-layer folding label sticker comprising: a first layer of sticker, a folded corner on the inner right side of the first layer of sticker, a second layer of sticker inside the folded corner, and a third layer of sticker connected to the left side of the second layer of sticker via the folded corner. Each of the first, second, and third layers of sticker has an inner sticker layer, which includes a wear-resistant layer, a tensile-strength reinforcing layer, and a moisture-proof and oxygen-barrier layer. The first layer of sticker has a wear-resistant layer to withstand daily touching and wiping, the inner side of the wear-resistant layer has a tensile-strength reinforcing layer to maintain the sticker's integrity when stretched, and the inner side of the tensile-strength reinforcing layer has a moisture-proof and oxygen-barrier layer. The folding corner has multiple layers to resist the effects of external moisture, oxygen, and odors on the sticker and its adhesion. Inside the folding corner are a flexible hinge base layer, an anti-fatigue reinforcement layer, and a lubricating buffer layer. The flexible hinge base layer provides a hinge-like elastic deformation capability, allowing it to be bent repeatedly. The anti-fatigue reinforcement layer is located inside the flexible hinge base layer to ensure performance after multiple operations. The lubricating buffer layer is located inside the anti-fatigue reinforcement layer to reduce friction between layers. These layers work together to ensure that the folding corner works smoothly and is durable during unfolding and folding. It is the key structural foundation for enabling labels to be repeatedly folded to view information on different layers.

[0007] Preferably, the first, second, and third sticker layers also include a cushioning and shock-absorbing layer and an adhesive bottom layer. The cushioning and shock-absorbing layer is located inside the moisture-proof and oxygen-barrier layer. This cushioning and shock-absorbing layer is composed of polyurethane (PU) foam, which has excellent resilience and low density. The adhesive bottom layer is located inside the cushioning and shock-absorbing layer. This adhesive bottom layer uses acrylic pressure-sensitive adhesive, which has good adhesive recovery and can quickly rebound and reset after being deformed by external force, thus enabling it to regain its adhesive function. Users can easily flip the sticker to read the content and restore it to its adhesive state, ensuring the functionality of the entire sticker during repeated viewing and use.

[0008] Preferably, the folded corner also includes a moisture-proof sealing layer and an adhesive reinforcement layer. The moisture-proof sealing layer is provided inside the lubrication buffer layer. The moisture-proof sealing layer is composed of an ultra-thin polyvinyl alcohol (PVA) film, which has good flexibility and adhesion. The adhesive reinforcement layer is provided inside the moisture-proof sealing layer. The adhesive reinforcement layer uses an epoxy resin and nano-silica composite adhesive to ensure that the materials at each level of the fold are tightly bonded and work together. It can prevent external moisture, dust and other factors from entering the fold, ensuring that the materials at each level of the fold are tightly bonded and avoiding external factors from affecting the performance of the folded corner and the entire sticker.

[0009] Preferably, the front surface of the first layer of sticker has a product description side to display the main relevant information of the product, the front surface of the second layer of sticker has a supplementary description side to provide further explanation of the product information, and the front surface of the third layer of sticker has a translation side to facilitate the provision of content in different languages ​​and meet multilingual needs.

[0010] Preferably, the trademark is set on the upper left side of the front of the first layer of sticker, which makes it easy for users to quickly identify the source of the product and other relevant information, thus improving the function of the sticker as a carrier of product identification.

[0011] Preferably, the wear-resistant layer uses a special polyurethane (PU) coating, which can resist damage caused by frequent contact and friction. The tensile reinforcement layer uses high-strength aramid fiber, which has excellent tensile strength. The moisture-proof and oxygen-barrier layer uses aluminum foil composite material, which can block water vapor, oxygen and odors, ensuring that the sticker maintains good performance as described in the working principle under different usage scenarios and extending its service life.

[0012] Preferably, the flexible hinge base layer is made of thermoplastic elastomer (TPE) material, which has the high elasticity of rubber and the processability of plastic. The fatigue-resistant reinforcement layer is made of high-strength aramid fiber woven fabric, which extends the service life of the folding part. The lubrication and buffer layer is made of polytetrafluoroethylene (PTFE) material, which reduces the friction between layers during folding and ensures that the folding angle works stably and reliably throughout the entire service life of the label sticker.

[0013] Compared with related technologies, the multi-layer folding label sticker provided by this utility model has the following beneficial effects:

[0014] 1. This utility model provides a multi-layer folding label sticker.

The cushioning and shock-absorbing layer 12 is provided inside the moisture-proof and oxygen-barrier layer 11. The cushioning and shock-absorbing layer 12 is composed of polyurethane (PU) foam, which has excellent resilience and low density. The adhesive bottom layer 13 is provided inside the cushioning and shock-absorbing layer 12. The adhesive bottom layer 13 uses acrylic pressure-sensitive adhesive, which has good adhesive recovery and can quickly rebound and reset after being deformed by external force, so that it can play its adhesive role again. Users can flip the sticker open to read the content and restore it to its adhesive state, ensuring the functionality of the entire sticker during repeated viewing and use.

[0025] In the embodiments of this utility model, please refer to Figure 1 and Figure 4 The folded corner 4 also includes a moisture-proof sealing layer 17 and an adhesive reinforcement layer 18. The moisture-proof sealing layer 17 is provided inside the lubricating buffer layer 16. The moisture-proof sealing layer 17 is composed of an ultra-thin polyvinyl alcohol (PVA) film, which has good flexibility and adhesion. The adhesive reinforcement layer 18 is provided inside the moisture-proof sealing layer 17. The adhesive reinforcement layer 18 uses an epoxy resin and nano-silica composite adhesive to ensure that the materials at each level of the fold are tightly bonded and work together.

[0026] In the embodiments of this utility model, please refer to Figure 1 and Figure 2 The first layer of sticker 1 has a product description surface 6 on its front side, which is used to display the main relevant information of the product. The second layer of sticker 2 has a supplementary description surface 7 on its front side, which can provide further supplementary explanations of the product information.

[0027] In the embodiments of this utility model, please refer to Figure 1 The first layer of sticker 1 has a trademark 5 on the upper left side, which makes it easy for users to quickly identify the source of the product and other relevant information, thus improving the function of the sticker as a carrier of product identification.

[0028] In the embodiments of this utility model, please refer to Figure 1 and Figure 3 The wear-resistant layer 9 uses a special polyurethane (PU) coating, which can resist damage caused by frequent contact and friction. The tensile reinforcement layer 10 uses high-strength aramid fiber, which has excellent tensile strength. The moisture-proof and oxygen-barrier layer 11 uses aluminum foil composite material, which can block water vapor, oxygen and odors, ensuring that the sticker maintains good performance as described in the working principle under different usage scenarios and extending its service life.

[0029] In the embodiments of this utility model, please refer to Figure 1 and Figure 4 The flexible hinge base layer 14 is made of thermoplastic elastomer TPE material, which has the high elasticity of rubber and the processability of plastic. The fatigue-resistant reinforcement layer 15 is made of high-strength aramid fiber woven fabric, which extends the service life of the folding part. The lubrication buffer layer 16 is made of polytetrafluoroethylene PTFE material, which reduces the friction between layers during folding and ensures that the folding angle 4 works stably and reliably throughout the entire service life of the label sticker.

[0030] The working principle of the multi-layer folding label sticker provided by this utility model is as follows: When it is necessary to view the information of each layer of the label sticker, start from the first layer sticker 1. The second layer sticker 2 and the third layer sticker 3 can be unfolded through the folding angle 4. The folding angle 4 plays a role in connection and rotation. Its internal flexible hinge base layer 14 provides a hinge-like elastic deformation capability. Because the thermoplastic elastomer TPE material has the high elasticity of rubber and the processability of plastic, the folding angle 4 can be repeatedly bent without breaking. During the unfolding process, the lubricating buffer layer 16 reduces the friction between the layers, making the unfolding action smoother. The fatigue-resistant reinforcing layer 15 ensures that the folding angle 4 can still maintain good performance after multiple unfolding and folding operations, extending its service life. When it is necessary to fold the label sticker, it is also operated through the folding angle 4. During the folding process, the internal structure of the folding angle 4 works together. The lubricating buffer layer 16 reduces the wear caused by friction between the layers, and the fatigue-resistant reinforcing layer 15 resists the stress generated by folding, preventing the folding angle 4 from being damaged prematurely. Meanwhile, the moisture-proof sealing layer 17 and the adhesive reinforcement layer 18 inside the folded corner 4 ensure that the materials at each level of the fold are tightly bonded, preventing external factors such as moisture and dust from entering the fold and affecting the performance of the label sticker. When the label sticker is touched, wiped, or comes into contact with other object surfaces, the abrasion-resistant layer 9 can prevent the sticker surface from being scratched or worn, thus ensuring the appearance of the sticker and the integrity of the information on it. During the pasting process, it may be pulled, or stretched due to accidental situations in the use environment. The tensile reinforcement layer 10 can prevent the sticker from being torn, maintaining the integrity of the sticker. In some humid or odorous environments, the moisture-proof and oxygen-barrier layer 11 can prevent moisture and odors from penetrating the sticker and affecting the content of the label or the adhesion. At the same time, blocking oxygen can prevent the material of the label sticker from being damaged by oxidation, extending its service life. When the goods are dropped, the cushioning and shock-absorbing layer 12 can absorb and disperse the impact force, protecting the internal structure of the sticker and the stability of the adhesion. After the stickers are pasted together, users can freely flip the stickers to read the content, and after reading, they can quickly spring back to their original position and resume their adhesive function.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
