How to choose high-quality colored PVC self-adhesive materials?
In the packaging, advertising, electronics, construction and other industries, colored PVC self-adhesive materials are popular for their bright colors, excellent durability and convenient pasting performance. However, the quality of products on the market is uneven. How to choose truly high-quality materials? This article will start from the three core performances of adhesion, weather resistance and color stability, and combine the industry experience of Baozhongbao Company to provide you with a professional purchase guide.
Analysis of key performance indicators
1. Adhesion-ensure long-term pasting without warping
Initial viscosity: The material should be able to bond quickly, reduce bubbles and wrinkles.
Sustained adhesion: Remain firm after long-term use to avoid falling off (especially suitable for outdoor scenes).
Applicable substrates: Need to match different surfaces (such as plastic, metal, glass, wall, etc.).
Baozhongbao solution:
As a pioneer in China's self-adhesive material industry (founded in 1993), we use high-precision gluing technology to ensure that the glue layer is uniform and stable, and provide different viscosity grades (such as permanent and removable) to meet diverse needs.
2. Weather resistance - resistance to UV, temperature and humidity
High-quality PVC self-adhesive materials must have:
UV resistance: no fading or cracking during long-term outdoor use.
Temperature adaptability: Maintain stable performance within the range of -20℃~80℃.
Waterproof and moisture-proof: avoid glue failure or material deformation.
Baozhongbao advantages:
Through weather-resistant modified formulas and multi-layer composite processes, our products can cope with extreme climates and are suitable for outdoor advertising, car film, building signs and other scenes, and ensure reliability through accelerated aging tests.
3. Color stability - keep bright and new for a long time
Anti-fading: dyes or pigments must be light-resistant and anti-oxidant.
Batch consistency: no color deviation in different production batches, suitable for high-demand fields such as brand packaging.
Surface treatment: matte/gloss effect needs to be uniform and flawless.
Baozhongbao technical guarantee:
Relying on 30 years of R&D experience, we use high-end masterbatch and UV protective coating to ensure long-lasting and bright colors, and can provide Pantone color card customization services to meet customers' personalized needs.
Purchase suggestions: How to identify high-quality products?
Test adhesiveness: Test on the target substrate to observe whether it is easy to curl or residual glue stains.
Check weather resistance certification: such as passing international standards such as ISO 4892 (artificial aging test).
Observe color uniformity: Compare samples from different batches to avoid color difference problems.
