Abstract
A method of manufacturing floor panels comprising at least one layer containing wood/plastic composite (WPC) adjacent an upper surface of the panels includes the step of providing a granulate of WPC in which natural fibers are encapsulated in polymer plastics which has been colored to a desired color for the upper surface. To form a sheet, a layer of granulate is melted and pressed. If several layers are used, only the upper layer is colored. The sheet is finished to form one or more panels. The coloring is done to imitate natural materials at least on the upper surface of the panel. Additional features can be taken to improve the appearance of the upper surface.
