The core advantages of laser silver & glossy silver label stickers lie in "visual texture" and "anti-counterfeiting properties", and their production focuses on the optimization of coating processes and the improvement of pattern precision. In the substrate pretreatment link, traditional processes use ordinary PET films with insufficient surface smoothness, leading to blurry laser effects. Now, high-transparency PET substrates (light transmittance over 92%) are adopted, and the surface roughness is reduced to Ra＜0.1μm through precision polishing, laying a high-quality foundation for subsequent coating. The coating link uses vacuum magnetron sputtering technology to deposit aluminum metal targets on the substrate surface with atomic-level precision, forming a metal film layer only 50-80nm thick. Compared with traditional evaporation coating processes, the film uniformity is increased by 40%, the silver luster is more full, and it is not easy to oxidize and fall off, maintaining the metallic texture for 1 year even when used outdoors.

The innovation of laser pattern production technology further enhances the visual effect. Traditional laser embossing uses a single texture template with a single pattern effect. Now, multi-layer holographic templates are made through laser engraving, which can achieve complex effects such as "dynamic light spots" and "gradient colors" — when the label is tilted, it can present silver reflections at different angles, and the visual layering is far beyond ordinary glossy silver stickers. At the same time, the embossing pressure and temperature are precisely controlled (pressure 5-10MPa, temperature 80-120℃ adjustable), ensuring that the laser texture is clearly replicated with a resolution of over 2000dpi, which can present fine brand logos and texture patterns, adapting to the bottle identification needs of luxury goods and high-end alcohol.

The integration of anti-counterfeiting functions is an important breakthrough of this type of label sticker. During the coating process, "invisible laser information" can be implanted — when irradiated by a laser of a specific wavelength, hidden numbers and patterns will appear on the label surface, which are invisible to the naked eye and require special equipment for identification, effectively preventing counterfeiting; some high-end models also adopt the "micro-text" process, embedding 0.1mm-sized text in the laser texture, which can only be seen with a magnifying glass, further improving the anti-counterfeiting level. In addition, the label edge can be designed with a "serrated anti-counterfeiting edge", and the die-cutting precision is controlled within ±0.05mm, making it difficult for counterfeiters to accurately replicate, providing double anti-counterfeiting protection for brand products.

In application fields, laser silver & glossy silver label stickers have become the "identity symbol" of high-end products: in the luxury goods field, they are used for brand identification of luggage and leather goods, and the metallic luster and dynamic laser effects enhance the high-end texture of products; in the high-end electronic products field, they are used for body labels of mobile phones and earphones, and the wear-resistant metal film can resist daily scratches and maintain clear identification for a long time; in the alcohol industry, they are used for bottle labels of high-end white wine and red wine, and the invisible anti-counterfeiting information can help consumers identify authenticity. With the increasing dual demand for "anti-counterfeiting + appearance" from brands, this type of label sticker will also develop new functions such as "temperature-changing laser" and "water-revealing color", further expanding high-end application scenarios.
