Vinyl stickers use PVC (polyvinyl chloride) as the core substrate, and their production and performance upgrades have always centered on "strengthening weather resistance" and "expanding functionality". In the substrate production process, traditional vinyl sticker substrates have uneven thickness (deviation ±0.05mm) and poor UV resistance, which are prone to fading and cracking when used outdoors. Now, by improving the extrusion process and using high-precision molds to control the substrate thickness, the deviation is reduced to ±0.02mm. At the same time, a UV anti-aging coating is applied on the substrate surface, and the UV blocking rate is increased to more than 90%, extending the outdoor service life from 1 year to 3-5 years, and ensuring that the pattern remains bright for a long time.​

The upgrade of adhesion control technology enables vinyl stickers to adapt to more scenarios. Traditional vinyl stickers mostly use permanent pressure-sensitive adhesives, which are difficult to remove after pasting and easy to leave adhesive residues. Now, by adjusting the adhesive formula, various adhesion specifications such as "removable type" and "low-residue type" have been developed: removable vinyl stickers use microsphere pressure-sensitive adhesives, which can be completely peeled off after pasting without adhesive residue, adapting to home wall stickers and temporary car decoration scenarios; low-residue type is suitable for the surface of electronic products and will not damage the product coating when replaced. At the same time, the adhesive layer thickness can be precisely controlled (adjustable from 5-20μm), ensuring firm adhesion on different material surfaces (glass, metal, plastic), with a peel strength of more than 5N/25mm.​

The optimization of printing and post-processing processes further enhances product added value. Using digital thermal transfer technology, complex printing effects such as gradient colors and metallic colors can be achieved on vinyl substrates, and the color saturation is 40% higher than that of traditional screen printing, adapting to high-end advertising and brand identification scenarios; in the post-processing link, in-mold embossing and partial UV processes are added, making the sticker surface present different textures such as matte and glossy, with better touch and visual effects. In addition, for special needs, flame retardants can also be added to vinyl stickers to make them meet the V0 flame retardant standard, adapting to the decoration needs of public spaces such as subways and shopping malls.​

In application fields, vinyl stickers have expanded from traditional outdoor advertising to multiple scenarios: in outdoor scenarios, they are used for bus stop signs and building exterior wall advertisements, and their weather-resistant and UV-resistant characteristics ensure long-term clarity; in home scenarios, as wall stickers and furniture decoration stickers, the removable and easy-to-replace features meet personalized decoration needs; in automotive scenarios, they are used for car body decals and interior decoration, and their scratch-resistant and wear-resistant properties adapt to the car use environment. With the continuous progress of material technology, vinyl stickers will also develop more functions, such as antibacterial and thermal conductivity, further expanding the application range.
