What Material is the Backing Paper of Color Change Film?
2 Answers
Automotive color change films are generally made of three materials: PVC, TPU, and Vinyl. Introduction to PVC Material: PVC, also known as polyvinyl chloride, has been extensively researched and tested for use in automotive color change films primarily because its inherent hardness provides protection to the car body. However, this level of protection gradually diminishes over time due to exposure to wind and sunlight, weakening the material's quality. Therefore, even with color change film applied, proper maintenance is still necessary. Introduction to TPU Material: The greatest advantage of TPU material is that it maintains excellent protective performance for the car body even in extremely cold or hot environments, while also causing minimal damage to the film itself. Most color change films made from this material are produced by foreign brands. Introduction to Vinyl Material: Vinyl, also known as ethylene, was first invented and used by the American brand SAQETH, a pioneer in the world's top automotive modification and decoration industry. Vinyl is durable, flexible, and easy to use, offering a wide range of colors and surface finishes. Vinyl films can produce color change products that look as good as or even surpass high-quality paint finishes.
I enjoy DIY car wrapping, and after my recent attempt, I realized how crucial the backing paper material is. Generally, car vinyl wrap backing paper uses silicone-coated or release paper, which has an ultra-smooth surface to prevent adhesive from sticking—peeling it off is effortless, leaving no residue. Low-quality backing paper, like plain paper, can leave debris or damage the film when removed, causing bubbles during installation—a real headache. High-quality silicone-coated backing feels soft yet durable, resists moisture, and ensures smooth application when kept dry. My advice when choosing branded films: pay attention to the backing paper quality—premium options often use thickened silicone-coated paper, reusable multiple times, saving money and being eco-friendly. In short, though small, the backing paper plays a huge role!
