A thermoplastic laminate plank is described wherein the thermoplastic laminate plank comprises a core, a print layer, and optionally an overlay. The core comprises at least one thermoplastic material and has a top surface and bottom surface wherein a print layer is affixed to the top surface of the core and an overlay layer is affixed to the top surface of the print layer. Optionally, an underlay layer can be located and affixed between the bottom surface of the print layer and the top surface of the core. In addition, a method of making the thermoplastic laminate plank is further described which involves extruding at least one thermoplastic material into the shape of the core and affixing a laminate on the core, wherein the laminate comprises an overlay affixed to the top surface of the print layer and optionally an underlay layer affixed to the bottom surface of the print layer.
