A resilient, three dimensional, perforated plastic webs which allow passage of water vapor and preferably air, and are resistant to the transmission of aqueous fluids at least in one direction. According to the present invention the perforated plastic webs consist of a liquid impervious polymeric film having open and closed capillaries. More than half of the capillaries are closed and preferably shorter than the capillaries with aperatures, and provide the resilient three dimensional web with an increased resistance crush and to collapse the capillaries under compression. The resilient, three dimensional, perforated plastic webs can be used as one of the layers of a backsheet in an absorbent articles, such as, sanitary napkins, pantiliners. baby diapers, adult incontinence, and the like.
