Absorbent article having an improved backsheet comprising a film as well as three-dimensional elastomeric polymer film with a capillary opening and closing the capillary

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 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 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 wearer in use. According to the present invention the articles are provided also with an apertured backsheet, preferably for breathability. The backsheet comprises at least one layer of a resilient, three dimensional, perforated plastic web as described above.
