The core component of decorative film is first and foremost the substrate layer, which forms the supporting framework of the entire membrane structure, determining its dimensional stability and mechanical properties. Common substrates include plastic films such as PVC, PET, and PP, as well as some composite materials. The substrate layer needs to possess a certain degree of flexibility and temperature resistance to adapt to processing techniques such as roll transport, cutting, hot pressing, or lamination, while ensuring that the decorative film is not easily deformed or broken during use.
The decorative film covers the surface of the substrate, giving it both protective and decorative effects. Functional coatings are typically composed of polyurethane, acrylic, or other weather-resistant coatings, providing properties such as scratch resistance, abrasion resistance, UV resistance, or water resistance. Furthermore, the coating can be adjusted in terms of gloss or surface texture to achieve different visual and tactile effects, such as high-gloss, matte, or silky finishes, thereby meeting decorative design requirements.
The decorative layer or pattern layer is the core visual element of the decorative film. Through printing, heat transfer, or embossing processes, colors, patterns, or special textures, such as wood grain, stone grain, or metallic finishes, are formed on the surface of the film. The decorative layer is tightly bonded to the substrate and functional coating, which not only enhances the aesthetics but also ensures that the pattern will not fade or peel off during processing and long-term use, achieving a balance between decorative effect and durability.
