description The invention relates to a breathable, plastic film, useful as a wall covering material. A low boiling additive, such as water, is added to a plastisol before extrusion. During extrusion and curing of the plastisol into a film or coating, the low boiling additive is volatilized and the resulting evolved gas perforates the forming film. In this manner a permeable plastic film, such as vinyl, is produced.
