Abstract: A process for extruding resilient, impact resistant thermoplastic strips having a metallic appearance by providing a non-metallic film strip of a material selected from the group consisting of polysulfones and polyether sulfones and having a vapor deposited metallized surface, the film strip having melting and deformation temperatures higher than those of a transparent thermoplastic to be extruded thereon and a resiliency and an elasticity at least as high as the resiliency and elasticity of such transparent thermoplastic when extruded thereon and, while feeding such film strip through a cross-head die, extruding the transparent thermoplastic about the metallized film strip and the resilient, impact resistant thermoplastic strip having a metallic appearance produced thereby.
