RESILIENT, THREE DIMENSIONAL POLYMERIC FILM COMPRISING OPEN AND CLOSED CAPILLARIES, AND ABSORBENT ARTICLE WITH IMPROVED BACKSHEET COMPRISING THE FILM

摘要

The present invention relates to resilient, three dimensional, perforated plastic webs which allow passage of water vapour, and preferably of air, and are resistant to the transmission of aqueous fluids at least in one directio n. According to the present invention the perforated plastic webs consist of a liquid impervious polymeric film having open and closed capillaries. More th an half of the capillaries are closed and preferably shorter than the capillari es with apertures, and provide the resilient three dimensional web with an increased resistance to crush and to collapse of the capillaries under compression. The present invention also relates to absorbent articles like baby diapers, adult incontinence articles and in particular to sanitary napkins or pantiliners which have a topsheet on the surface facing the weare r in use. According to the present invention the articles are provided also wi th an apertured backsheet, preferably for breathability. The backsheet comprise s at least one layer of a resilient, three dimensional, perforated plastic web as described above.
