Abstract
The present invention relates to a liquid-permeable casing sheet (1) for absorbent sanitary articles, such as sanitary napkins, incontinence guards and diapers. According to the invention, the casing sheet (1) includes a first layer (2) which is corrugated across at least a central part of its surface so as to provide a row of mutually parallel waves having wave crests (3) and wave troughs (4), wherein the wave crests form an article contact surface with the wearer's body when the article is in use. The casing sheet also includes rows of through-penetrating openings (6) which extend perpendicularly to the corrugations or waves and each of which opening passes through a wave crest (3). The invention also relates to a method for producing such a casing sheet.
