Abstract: A system and associated process for creating an extruded sheet having a decorative surface effect, such as plastic for example are presented. A roll of decorative plastic film for use in such system and process is also presented. Viscous materials are provided and fed through an extruder module and feed block to form a stream of viscous material. A die positioned downstream forms the stream of viscous material into a sheet of material and a calander having a set of rolls smoothes the sheet of material after it is released by the die. A film application assembly cooperates with the calander to apply a decorative plastic film to a surface of the sheet of material. The film application assembly includes a support structure for holding a roll of the decorative plastic film and a film feeding mechanism configured to direct the decorative plastic film to position a surface of the decorative plastic film opposite the surface of the sheet of material.
