METHOD FOR PRODUCING A DECORATED WALL PANEL OR FLOOR PANEL

The present invention relates to a method for producing a decorated wall panel or floor panel, comprising the method steps of: a) providing a first molten polymer mass and a second molten polymer mass; b) extruding the molten polymer masses, wherein in particular each polymer mass is extruded using a separate extruder, wherein the molten polymer masses are laid one on top of the other in layers; c) ejecting the molten polymer masses laid one on top of the other in layers through a nozzle; d) calibrating the molten polymer masses laid one on top of the other in layers to form a planar carrier having at least one carrier layer, which comprises the first polymer mass, and a sealable layer, which comprises the second polymer mass and contacts the carrier layer. The invention also relates to planar carriers and decorative panels produced in this way, and to a device for carrying out the method.
