    Abstract: An improved packaging material may include a substrate which is normally susceptible to permeation by substances such as oil or grease. A colorant layer may be applied to the outer surface of the substrate. The colorant layer may be of a color chosen to closely resemble or to overpower the appearance of a stain on the substrate which would otherwise be caused by the substances. In this manner, the colorant layer serves to mask the stain which would otherwise be caused by substances permeating through the substrate. A second colorant layer may optionally be provided over the first colorant layer to provide a uniform background of a desired color. Graphics, e.g, text and/or images, may then be applied to the first or second colorant layer in a conventional manner.
