Abstract
A polymeric molded device having an exemplary use as a structural or reinforcing member for a vehicle includes a co-extruded multilayer film. The multilayer film includes at least a clear layer, a color layer joined to the clear layer, and a bulk layer joined to the color layer. The multilayer film is thermoformed into a structural shape. A foam layer is bonded to the bulk layer by injection or extrusion molding. The film and the foam layer, when bonded, form the structural member. The co-extruded multilayer film can also include the foam layer before thermoforming.
