ABSTRACT In the manufacture of a paint-coated stretchable film which is useful as a covering for automobile panels and other articles, a stretchable carrier film is formed by extruding a thermoplastic polymer composition onto a heat resistant temporary carrier film. The extruded layer i coated with paint or other layers and dried initially at a moderate temperature and finally at a high temperature which exceeds the heat deformation temperature of the stretchable carrier film but not of the heat resistant temporary carrier film. This shortens drying time and/or reduces residual solvents in the dried layers. The temporary carrier film, which is later stripped away, resists deformation of the laminate as it is drawn under tensile stress through the coating and high temperature drying stages.
