Abstract

a. Sac en plastique comprenant une une valve de remplissage et une couche filtrante perméable à l'air s'étendant de l'intérieur du sac jusqu'à l'extérieur. b. Cette couche filtrante, par exemple un matériau feutré ou non tissé, est recouverte au moins partiellement par le fond du sac. La couche filtrante forme de préférence une poche fermée située à l'opposé de la valve de remplissage. La couche filtrante peut en outre entourer le tube formant valve de remplissage. c. Applications pour sacs destinés à contenir des produits pulvérulents.at. A plastic bag comprising a fill valve and an air permeable filter layer extending from the inside of the bag to the outside. b. This filter layer, for example a felted or non-woven material, is covered at least partially by the bottom of the bag. The filter layer preferably forms a closed pocket located opposite the fill valve. The filter layer may further surround the filling valve tube. vs. Applications for bags intended to contain powdery products.
