PVC decorative film is a novel decorative material manufactured by calendering and laminating a polyvinyl chloride (PVC) base with various additives; its primary constituents include PVC resin, plasticizers, and stabilizers. The production process incorporates patented technologies such as multi-layer lamination and embossing, involving steps like twin-screw extrusion, plasma surface treatment, and ultrasonic vibration-assisted lamination to enhance heat resistance and flexibility. Compatible with substrates such as wood, metal, and plastic panels, the material is widely used in home appliances, interior decoration, vehicle interiors, and architectural curtain walls, offering properties such as water and moisture resistance, wear resistance, and ease of cleaning.
Installation requires specialized tools-including base primers, squeegees, and heat guns-and involves procedures such as substrate preparation, precision cutting, and film positioning; care must be taken to avoid scratching the surface with hard objects after installation. Product categories include solar control window films and safety window films; in 2024, the global decorative film market reached sales of US$723 million, with major manufacturers including 3M and Eastman. The Chinese market is experiencing rapid growth, with the architectural window film market reaching a scale of RMB 7.897 billion in 2023.
