Teijin's Decorative Films
In recent years, there has been a demand for reducing environmental impact through paintless solutions and improving design aesthetics, such as light transmissive indication. As a way to solve this problem, we have adopted insert molding and out-mold molding of decorative films to eliminate the need for painting, improve functionality (scratch resistance, chemical resistance, weather resistance), design (light transmission, 3D shape, seamless), and studies are underway to integrate large parts. In addition, the method of forming electronic circuits on films for the purpose of reducing the number of components is also studied. The Resin and Plastic Processing Business Unit of Teijin continues the development of next-generation decorative PC-based films by utilizing Teijin's unique polymer and compound technologies as base material films that enable such approaches.
For any difficulties in these methods, please contact Teijin.
