Description

Technical Field

[0001] This utility model relates to the field of encryption label technology, specifically to a raised and recessed refractive encryption label. Background Technology

[0002] Currently, with the rapid development of e-commerce, a wide variety of goods are constantly entering the market. Many unscrupulous individuals, for their own profit, are mass-producing counterfeit and substandard products. Counterfeit and substandard goods not only cause serious economic losses to legitimate product manufacturers but also seriously endanger the lives and property of consumers, causing extremely negative social impacts. With technological advancements, anti-counterfeiting methods are becoming increasingly sophisticated and diversified. To prevent their products from being counterfeited, most manufacturers use anti-counterfeiting labels to protect their goods.

[0003] However, the current anti-counterfeiting labels are relatively weak, easily damaged, and easily imitated by counterfeiters, resulting in unsatisfactory anti-counterfeiting effects.

[0004] To address the aforementioned issues, this application proposes an embossed refractive encryption label. Utility Model Content

[0005] This utility model aims to provide an embossed and refractive encrypted label, mainly to solve the problem that existing anti-counterfeiting labels are weak, easily damaged, and easily imitated by counterfeiters, resulting in unsatisfactory anti-counterfeiting effects.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A raised and recessed optical encryption label includes a label body, a reinforcing layer fixedly connected to the back of the label body, an adhesive layer fixedly connected to the side of the reinforcing layer away from the label body, a release layer bonded to the side of the adhesive layer away from the reinforcing layer, a QR code on the front of the label body, and anti-counterfeiting raised dots above the QR code on the front of the label body.

[0008] The working principle and beneficial effects of this utility model:

[0009] 1. Working principle: When using this encrypted label, simply tear off the release layer and fix the label body onto the corresponding product through the adhesive layer. You can then use it normally. By scanning the QR code on the label body, you can obtain detailed information about the product. The anti-counterfeiting embossing on the label body provides a better anti-counterfeiting effect when the label body is illuminated with light due to the different reflective properties of the embossing.

[0010] 2. Beneficial effects: The reinforcement layer on the back of the label body can effectively improve the strength of the encrypted label, thereby effectively extending the service life of the encrypted label. The QR code on the label body can be scanned to quickly learn about the product's detailed information. When light shines on the anti-counterfeiting embossed dots on the label body, the different reflective degrees of the embossed dots will achieve a better anti-counterfeiting effect.

[0011] Preferably, the reinforcing layer includes a fixing shell fixedly connected to the back of the label body. The fixing shell has a cavity inside, and a metal mesh is fixedly connected inside the cavity. The reinforcing layer includes the fixing shell, which can be made of plastic material. Due to the high strength of plastic and the metal mesh inside the fixing shell, the strength of the encrypted label can be effectively improved, thereby further extending the service life of the encrypted label.

[0012] Preferably, a protective layer is fixedly connected to the front of the label body at the QR code location, and the protective layer is transparent. The protective layer on the label body at the QR code location covers the QR code, which can provide good protection for the QR code and effectively prevent the QR code from fading or being damaged, thus preventing it from becoming unusable.

[0013] Preferably, the release layer is a polyester film coated with an organosilicon release agent, the thickness of the release layer is 5μm to 8μm, and a protrusion is fixedly connected to one side of the release layer. The organosilicon release agent can form a low surface energy coating on the surface of the polyester film, so that the material in contact with it can be easily separated from it, ensuring that the attached material can be completely and cleanly removed from the film during use without any residue or other problems. The release layer can be easily and quickly removed by pulling the protrusion provided on one side of the release layer.

[0014] Preferably, the adhesive layer is formed by coating with a silicone-modified polyurethane adhesive, and the thickness of the adhesive layer is 1μm to 3μm. The silicone-modified polyurethane adhesive is prepared by ball milling polyurethane resin, neoprene rubber, and PDMS silicone modifier. This adhesive is resistant to acids and alkalis, sweat, high and low temperatures, and has strong initial tack. Therefore, coating the adhesive layer with a silicone-modified polyurethane adhesive can effectively improve the stability of the encrypted label during use.

[0015] Preferably, the protective layer is made of fluoropolymer material and the thickness of the protective layer is 3-6 μm. Fluoropolymer is a commonly used hydrophobic film-forming material. Due to its compact molecular structure and stable chemical properties, it can withstand a variety of chemicals and high temperatures. Therefore, the protective layer is made of fluoropolymer material, which can not only provide good waterproofing for the QR code, but also provide better protection for the QR code.

[0016] Preferably, the label body is made of high-density polyethylene material, and the thickness of the label body is 10-20μm. High-density polyethylene material has excellent waterproof performance and is tough and tear-resistant, so making the label body of high-density polyethylene material can further extend the service life of the encrypted label.

[0022] 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.

[0023] Please see Figure 1-4A raised-reflective encryption label includes a label body 1, which is made of high-density polyethylene material with a thickness of 10-20 μm. High-density polyethylene material has excellent waterproof performance and is tough and tear-resistant, so making the label body 1 with high-density polyethylene material can effectively extend the service life of the encryption label. A reinforcing layer 2 is fixedly connected to the back of the label body 1, which can effectively improve the strength of the encryption label. An adhesive layer 3 is fixedly connected to the side of the reinforcing layer 2 away from the label body 1. The adhesive layer 3 is made by coating with silicone-modified polyurethane adhesive, and the thickness of the adhesive layer 3 is 1 μm-3 μm. The silicone-modified polyurethane adhesive is prepared by ball milling polyurethane resin, neoprene rubber and PDMS silicone modifier. This adhesive is resistant to acids and alkalis, sweat, high and low temperatures, and has strong initial tack. Therefore, the adhesive layer 3 is made by coating with an organosilicon-modified polyurethane adhesive, which can effectively improve the stability of the encrypted label during use. A release layer 4 is adhered to the side of the adhesive layer 3 away from the reinforcing layer 2. The release layer 4 is a polyester film coated with an organosilicon release agent, with a thickness of 5μm to 8μm. The organosilicon release agent can form a low surface energy coating on the surface of the polyester film, allowing materials in contact with it to easily separate from it. This ensures that the attached materials can be completely and cleanly removed from the film during use, without any residue. A protrusion 11 is fixedly connected to one side of the release layer 4. By pulling the protrusion 11, the release layer 4 can be easily and quickly peeled off. A QR code 5 is provided on the front of the label body 1. By scanning the QR code 5, detailed information about the product can be quickly obtained. A protective layer 10 is fixedly connected to the QR code 5 on the front side. The protective layer 10 is transparent and provides good protection for the QR code 5, effectively preventing it from fading or being damaged and thus becoming unusable. The protective layer 10 is made of fluoropolymer material and has a thickness of 3-6 μm. Fluoropolymer is a commonly used hydrophobic film-forming material. Due to its compact molecular structure and stable chemical properties, it can withstand various chemicals and high temperatures. Therefore, the protective layer 10, made of fluoropolymer material, not only provides good waterproofing for the QR code 5 but also provides better protection for it. Anti-counterfeiting embossing 6 is set above the QR code 5 on the front side of the label body 1. When light shines on the anti-counterfeiting embossing 6 on the label body 1, the different reflective degrees of the anti-counterfeiting embossing 6 provide a better anti-counterfeiting effect.

[0024] like Figure 3As shown, the reinforcing layer 2 includes a fixed shell 7 fixedly connected to the back of the label body 1. The fixed shell 7 has a cavity 8 inside, and a metal mesh 9 is fixedly connected inside the cavity 8. The reinforcing layer 2 includes the fixed shell 7, which can be made of plastic material. Due to the high strength of plastic and the metal mesh 9 inside the fixed shell 7, the strength of the encrypted label can be effectively improved, thereby further extending the service life of the encrypted label.

[0025] As can be seen from the above, the specific embodiments of this utility model are as follows:

[0026] When using this encrypted label, pull the protrusion 11 to remove the release layer 4, and fix the label body 1 to the corresponding product through the adhesive layer 3. It can then be used normally. By scanning the QR code 5 on the label body 1, you can quickly obtain detailed information about the product. When the anti-counterfeiting protrusions 6 on the label body 1 are illuminated with light, the different reflective properties of the anti-counterfeiting protrusions 6 can achieve a better anti-counterfeiting effect.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
