Abstract
A backing film for incorporation as a backing layer in a resilient floor covering or a floor tile having at least two laminae and a method for making such a backing layer whereby wastage is reduced when the color of the upper lamina is changed. Where there are two backing films having two or three laminae making up the backing layer the intermediately colored film resulting from a change in the color of the upper lamina can be utilized without further processing on the second backing film where color is not essential. Where there are three laminae making up a backing film the desired color is introduced and established in the bottom lamina before the supply of the original color to the upper lamina is stopped. The film can then be turned over for use with the former bottom lamina becoming the upper lamina.
