<p>The present invention relates to absorbent articles such as sanitary napkins and panty liners which are breathable by the incorporation of a breathable backsheet therein, and have a reduced tendency to exhibit garment wet through. The breathable backsheets comprise at least one moisture vapour permeable, apertured layer selected from wovens or apertured films comprising a nonsoluble, liquid swellable material such as polyvinyl alcohol, which upon contact with the fluid discharge the material swells. This causes the apertures of the layer to close and hence prevents the passage of liquid through the backsheet onto the garment of the wearer.</p> |
