The invention presents a flexible, air-permeable plastic sheet comprising a large number of ribs of a first direction (Y1, Y2 ...) which each have mutually opposite sides (2, 3) extending in the first direction (Y) and bent downwards, and a large number of ribs of a second direction (X1, X2 ...) which each have mutually opposite sides (4, 5) extending in the second direction and bent downwards, so that each pair of adjacent ribs of a first direction and each pair of adjacent ribs of a second direction which cross these ribs of a first direction jointly delimit an air-permeable empty space. At each crossing point (C1, C2, C3, C4) one of the ribs is arched upwards and the opposite side edges of this rib cross the upper side (T1, T2) of the other ribs. Features of the plastic sheet according to the invention are less gloss and less tacky handle, and the sheet is preferably used as a top layer of a disposable hygienic article to be worn on the body. <IMAGE> |
