Unveiling the Advantages of Laser Silver and Glossy Silver Label Stickers: Visual Texture and Anti-Counterfeiting Features
Oct 29,2025
The core value of holographic tamper-evident stickers lies in "anti-counterfeiting reliability" and "tampering identifiability", and their production focuses on the optimization of holographic technology and anti-transfer processes. In the holographic pattern production link, traditional 2D holographic technology has weak pattern layering and is easy to be counterfeited. Now it has been upgraded to 3D dynamic holographic technology — by recording the 3D information of objects through multi-beam interference, the label surface can present effects such as "360° dynamic rotation" and "three-dimensional suspension", which can be clearly identified by the naked eye, and counterfeiters need to invest extremely high costs to replicate. At the same time, the holographic master is made by nano-lithography technology, with a minimum line width of 50nm, and the pattern details are far beyond traditional processes, further increasing the counterfeiting threshold.
The design of the tamper-evident structure is a key innovation of this type of sticker. Traditional tamper-evident stickers mostly use "fragile substrates", but they are difficult to trace completely after breaking. Now a "layered transfer" structure has been developed: the substrate is divided into a surface layer (holographic layer) and a bottom layer (adhesive layer). When trying to peel off the sticker, the surface layer will separate from the bottom layer, the holographic pattern will break and cannot be restored, and the bottom layer will leave the word "VOID" (invalid), intuitively indicating that the product has been tampered with. Some high-end models also add a "temperature-sensitive color-changing" tamper-evident layer. When the ambient temperature exceeds 40℃ (such as trying to transfer with a heat gun), the label will change from transparent to red, further strengthening the tamper-evident effect.
The customized development of adhesives adapts to different application scenarios. For paper substrates of pharmaceutical and food packaging, low-viscosity pressure-sensitive adhesives are used, which can adhere firmly after pasting and will not damage the packaging when peeled off; for plastic casings of electronic digital products, high-strength acrylic adhesives are used, with a peel strength of more than 8N/25mm, ensuring that the sticker cannot be completely transferred once pasted; for metal surfaces, weather-resistant adhesives are used, which can maintain stable adhesion in the environment of -30℃-80℃, adapting to the anti-counterfeiting needs of outdoor equipment. In addition, the adhesive layer can also add "fluorescent particles", which present specific wavelength fluorescence under ultraviolet irradiation, providing a double verification method for anti-counterfeiting.
In application fields, holographic tamper-evident stickers have become a "safety barrier" in many industries: in the pharmaceutical field, they are used for packaging identification of vaccines and prescription drugs, the tamper-evident structure ensures that the drugs are not opened, and the holographic information can be linked to the traceability system to query production and circulation information; in the electronic digital field, they are used for anti-counterfeiting stickers on mobile phones and computers to prevent products from being refurbished and tampered with; in the luxury goods field, they are used for identity identification of luggage and watches, and the combination of layered transfer structure and holographic anti-counterfeiting effectively combats the circulation of counterfeit goods. With the increasing market demand for product safety and traceability, this type of sticker will also be combined with RFID technology to achieve "visual anti-counterfeiting + electronic traceability" double protection, further expanding the application boundary.
