Z 257 (R) Abstract of the Invention A moisture-permeable film from thermoplastic material as covering layer for absorbent layers of an article has embossments with openings arranged at their ends. The embossments are formed in such a way that their side walls extend at approximately right angles to the base surface. As a result the embossments form capillaries with a cross-section which does not change over the entire depth of the embossments. The embossments and the openings can have any shape. Preferred are slit-shaped embossments having dimensions of 0.3 by 2 mm, which have been arranged in rows, staggered and in alternating direction.
