In the context of increasingly fierce market competition, brands are facing more severe threats from counterfeit products. Traditional single-layer anti-counterfeiting labels, due to their simple structure and ease of imitation, have gradually weakened their anti-counterfeiting effectiveness. The industry is increasingly demanding more intelligent and covert innovative anti-counterfeiting solutions. Shenzhen Huaxin Anti-counterfeiting Technology Co., Ltd., having deep ploughing the anti-counterfeiting field for 20 years， has developed double-layer QR code anti-counterfeiting labels and double-layer self-adhesive anti-counterfeiting labels， building a solid security barrier for brand owners.
I. Technology principle of double-layer anti-counterfeiting labels： Unveiling the mystery of the backing layer
Huaxin Anti-counterfeiting integrates precise physical structure design and digital information management in the printing technology of double-layer anti-counterfeiting labels.
Technology principle and production process
The core of the label lies in the physical structure of "revealing the backing layer". The label consists of the top layer (revealed layer) and the bottom layer (backing layer). Its production relies on specialized anti-counterfeiting label printing equipment and methods. The key to this technology lies in the precise physical structure and the corresponding information verification mechanism. The top layer usually has visible "visible code" QR codes and verification instructions， while the bottom layer is firmly adhered to the product and contains hidden "hidden code" QR codes. During the verification process， a one-to-one correspondence between "visible code + hidden code" must be achieved， and through a dual verification mechanism， counterfeiting and imitation behaviors can be completely prevented from the root.
In the production process， Huaxin Anti-counterfeiting's equipment is equipped with a first inkjet printing device and a second inkjet printing device， which can print corresponding QR codes at the same label position. When the top layer is output from the first inkjet printing device， the glue plate will apply glue at the bottom， and then the top layer and the bottom layer will simultaneously enter the pressing mechanism for pressing， forming a double-layer label strip. This compact equipment structure ensures that the hidden QR code is effectively covered by the top layer， preventing information leakage.
In addition to the basic double-layer structure， Huaxin Anti-counterfeiting's labels can also adopt special structural designs to enhance anti-counterfeiting effects. For example， some labels include components such as sponge substrates， strip grooves， and vesicles. The vesicles are filled with colored solutions. When the label is opened or subjected to pressure， the release or change of the colored solution can provide additional， visible authenticity identification features.
II. Core Advantages: Why It Is So Popular
Strong anti-transfer ability: Due to its "instant damage upon removal" characteristic, the label cannot be reused once it is completely torn off, effectively preventing recycling and reuse.
Effective prevention of QR code duplication: A single QR code is easily copied and duplicated, while the double-layer anti-counterfeiting label verifies through the corresponding relationship of two QR codes. Even if the imitator copies the surface "visible code", they cannot obtain the hidden, unique "secret code" on the bottom layer, thus solving the problem of easy copying of ordinary QR codes.
Large information carrying capacity and strong functional scalability: The double-layer structure provides a larger space for information display. Enterprises can not only place anti-counterfeiting information but also integrate brand promotion, product usage instructions, promotional activities, etc., increasing the product's added value.
Additional functions: Besides the core anti-counterfeiting function, this type of label is also an important information and interaction platform. Based on the "one item, one code" technology, enterprises can integrate various functions such as product traceability, anti-stealing management, and intelligent marketing on the label. This makes the label no longer a simple anti-counterfeiting tool but a crucial bridge connecting the brand with consumers, enhancing brand image and user loyalty.
Enhancing brand image and consumer trust: The well-made double-layer labels themselves can reflect the brand's attitude of being responsible for product quality and consumers. When consumers can personally verify the authenticity of the product through a rigorous process, they will have a stronger sense of trust in the brand.
III. Application Scenarios
It is widely used in industries with high requirements for anti-counterfeiting such as alcohol, cosmetics, jewelry, electronic products, etc. These industries' products often have high value or are closely related to consumers' safety and health, requiring strong brand protection measures.
In the cosmetics industry, it can effectively enhance the product's grade perception and attract consumers' attention; in the food and pharmaceutical industries, it can be used to display drug usage instructions and anti-counterfeiting traceability information, enhancing product safety and consumer trust; in the electronics industry, it is widely applied due to its excellent visual effect and information carrying capacity.
IV. Technology Stack and Material Selection
Huaxin Anti-counterfeiting can integrate multiple advanced anti-counterfeiting technologies into the double-layer label, building multiple anti-counterfeiting barriers. For example, by integrating laser holographic technology, the label presents a dynamic and three-dimensional visual effect; by applying special inks such as temperature-sensitive and water-dropping disappearing inks, it provides intuitive methods for authenticity identification through physical or chemical reactions. The combined application of multiple technologies significantly increases the difficulty of counterfeiting and the cost of fraud.
To further enhance the anti-counterfeiting level, the label can be combined with other anti-counterfeiting technologies such as holographic laser laser, special ink printing, and microtext. The combined application of multiple technologies forms a complex technical barrier, significantly reducing the possibility of being copied.
The material selection for labels is extremely diverse, covering gelatin board paper, copper plate paper, laser laser film, PET, PVC, etc. It can be flexibly matched according to the environmental requirements and functional demands of different application scenarios, suitable for various usage scenarios from food packaging to industrial products. At the same time, Huaxin Anti-counterfeiting has established a complete quality control system, conducting comprehensive testing of multiple core indicators such as stickiness, water resistance, and heat resistance; relying on advanced detection equipment, ensuring that each label meets strict quality standards, guaranteeing the stability performance of the product in various environments.
V. Enterprise Strength
Since its establishment in 2008, Huaxin Anti-counterfeiting has grown into a "double high-tech" enterprise (a national high-tech enterprise and a Shenzhen high-tech enterprise) with 40 anti-counterfeiting patent technologies by virtue of continuous technological innovation and strict quality control.
The company has set up an independent research and development center and has established stable cooperative relationships with multiple universities and research institutions such as the Chemical Engineering College of Peking University, Shenzhen University, and Huazhong University of Science and Technology. Through the deep integration of industry, academia, and research, it provides continuous impetus for technological innovation. At the production end, Huaxin Anti-counterfeiting is equipped with advanced production lines and testing equipment such as fully automatic printing machines, laser engraving machines, and precision testing instruments; through vertical integration of the supply chain system, it strictly controls the entire process from raw material procurement to product manufacturing, ensuring the stability and reliability of the products.
The company's label products have extremely strong environmental adaptability. Labels produced with special materials can withstand temperatures as low as -50℃ in extremely cold environments and remain free of bubbles and creases for 10 years.
