Abstract
L'invention concerne l'industrie des pellicules. Elle a pour objet une pellicule perméable aux liquides faite d'une matière thermoplastique et convenant comme couche de couverture pour une couche absorbante d'un produit manufacturé. La pellicule comporte des gaufrures 2 comprenant des ouvertures 5 à leurs extrémités. Les gaufrures 2 sont façonnées de manière que leurs flancs soient à peu près perpendiculaires à la surface principale 1 de la pellicule. De cette façon, les gaufrures constituent des capillaires dont la section est constante sur la hauteur des gaufrures. Les gaufrures et ouvertures peuvent avoir une forme quelconque. Elles ont de préférence la forme de fentes de 0,3 mm fois 2 mm, qui sont décalées par rangées et ont des orientations alternantes. Ces pellicules perméables sont préférées pour des langes à jeter.
