Method of preparation of a decorated wall or floor panels

A method for producing a decorated wall or floor panel, comprising the steps of:

• a) providing a first molten polymer mass and a second molten polymer mass;
• b) extruding the first and the second molten polymer masses, wherein each polymer mass is extruded by a separate extruder, wherein the molten polymer masses are layered on top of each other,
• c) expelling the layered molten polymer masses through a die;
• and
• d) calibrating the layered molten polymer masses in order to form a plate-shaped carrier comprising at least one carrier layer comprising the first polymer mass and a sealable layer contacting the carrier layer and comprising the second polymer mass, wherein the method further comprises the method step:
• e) applying a film onto at least a partial area of the sealable layer of the plate-shaped carrier, wherein the film comprises at least one top layer, wherein the top layer comprises an inner side, an outer side and a decorative layer applied to the inner side of the top layer, and wherein the film is applied to the sealable layer in such a way that the outer side of the top layer faces away from the plate-shaped carrier, wherein said top layer comprises a fourth polymer, wherein said fourth polymer is a vinyl polymer or consists essentially thereof, wherein said fourth vinyl polymer is a homopolymer or a copolymer, and wherein the fourth vinyl polymer comprises a polypropylene-based vinyl polymer, or a polypropylene copolymer, or a polypropylene copolymer selected from the group consisting of a propylene-ethylene random copolymer, a propylene-ethylene block copolymer, and a polypropylene-ethylene-butylene copolymer.
