PVC glossy black sheets are high-quality black sheets manufactured through precision extrusion using premium polyvinyl chloride (PVC) resin and high-grade black masterbatch. They feature a single glossy side with a matte opposite side, or dual glossy surfaces. Renowned for their deep black appearance, excellent gloss, and good processability, these sheets are highly favored in high-end packaging, decoration, and industrial design applications.
