Zusammenfassung:	A process and related assembly for creating an extrusion molded article with a chemically applied outer film. An extruded base material is formed during a first extrusion operation, following which a multi-layer film is bonded to the base material while the base material still at an above ambient temperature. The multi-layer film further includes successive layers of each of a polypropylene (PP), an adhesive, a polyethylene terephthalate (PET), a coating and s subsequent surface PET. The step of bonding of the film further occurs during an intermediate step between the first extrusion operation for forming the base material according to a given profile section and a subsequent extrusion operation for applying additional material along an edge of the film, the additional material including profile wings as required for a given design.
