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.The invention relates to the film industry. It relates to a liquid permeable film made of a thermoplastic material and suitable as a cover layer for an absorbent layer of a manufactured product. The film comprises embossings 2 comprising openings 5 at their ends. The embossments 2 are shaped so that their sides are approximately perpendicular to the main surface 1 of the film. In this way, the embossments constitute capillaries whose section is constant over the height of the embossments. The embossings and openings can have any shape. They preferably have the form of slits of 0.3 mm times 2 mm, which are staggered by rows and have alternating orientations. These permeable films are preferred for disposable diapers.
