Self-adhesive anti-counterfeiting labels are a technological carrier that generates unique identifiers on the label surface through physical or chemical means. They are widely used in product traceability, anti-counterfeiting management, and digital marketing scenarios. Their core function is to assign a unique identity to each product through "one item, one code" technology. Consumers can scan the code to verify authenticity and obtain product information, while businesses can track the product's distribution path through a backend system, achieving end-to-end supply chain control.
The anti-counterfeiting function of self-adhesive anti-counterfeiting labels relies on a multi-layered technological structure: the bottom layer is a removable or fragile self-adhesive substrate that cannot be restored after being torn; the middle layer integrates optical anti-counterfeiting elements, such as rainbow holography, optical liquid crystal, or micro-nano structures, which present dynamic visual effects when illuminated by special light; the surface layer is covered with a scratch-off silver coating or a variable QR code, concealing key information. Among these, dynamic encoding technologies such as color-changing logical QR codes and fingerprint codes generate uncopyable patterns through algorithms, combined with physical anti-counterfeiting measures such as hidden codes, forming a dual verification mechanism.
The labels require a matching traceability and anti-counterfeiting system, which comes in two versions: a standard version and a custom-developed version. The standard version offers standardized functions, supporting one-time setup or configurable modes. Enterprise users can choose custom development, integrating production, warehousing, and logistics data. After consumers scan the code via an H5 page, WeChat official account, or mini-program, the system compares the label code with database records in real time, providing information such as product authenticity, production batch, and distribution node. If abnormal distribution occurs (e.g., cross-regional sales), the system automatically triggers an alert, helping businesses quickly pinpoint the problem.
Beyond basic anti-counterfeiting, the labels can extend to digital marketing functions. For example, businesses can embed interactive modules such as red envelopes, points, and lotteries on the scanning page, transforming anti-counterfeiting verification into a user engagement point. In supply chain management, "one item, one code" binds product and logistics information, enabling dynamic inventory monitoring and distributor behavior analysis. Technically, the labels support customizable shapes (square, circle, irregular shapes, etc.) and multi-color printing to adapt to different packaging design needs; their fragile and transfer-resistant characteristics ensure that once applied, the labels cannot be completely peeled off, preventing reuse.
The core advantages of this technology lie in its "uniqueness" and "traceability": each label has an independent and unpredictable code, which, combined with blockchain or encryption algorithms, can further enhance security; the traceability system records data from the entire process of a product from production to the end consumer, providing decision support for businesses. In practical applications, a fast-moving consumer goods (FMCG) brand reduced its cross-selling rate by 60% by deploying such a system, while its QR code interactive activities increased consumer repurchase rates by 25%. Future technological iterations include more refined micro-nano anti-counterfeiting structures, AI-driven abnormal behavior analysis models, and deep integration with IoT devices.
