Decorative film is a new type of decorative material made from polyvinyl chloride (PVC) as the base material, with additives added through calendering and lamination. Its main components include PVC resin and additives such as plasticizers and stabilizers. The production process encompasses patented technologies such as multi-layer composite processing and lamination embossing, involving steps such as twin-screw extrusion, plasma surface treatment, and ultrasonic vibration-assisted lamination, which improves heat resistance and flexibility. This material can be laminated with substrates such as wood, metal, and plastic sheets, and is widely used in household appliances, interior decoration, vehicle interiors, and building curtain walls, possessing waterproof, moisture-proof, wear-resistant, and easy-to-clean properties.
Construction requires specialized base film, scrapers, and hot air blowers. The process includes substrate treatment, precise film cutting, and film positioning. After construction, scratches from hard objects should be avoided. Product types include solar control window films and security window films. In 2024, the global decorative film market reached $723 million in sales, with major manufacturers including 3M and Eastman. The Chinese market is growing rapidly, with the architectural window film market reaching 7.897 billion yuan in 2023.
