Abstract

A plastics bag 1 has a filling valve 18, and an air-permeable fine-materials-filtering layer 22a, 22b, extending from the interior of the bag to the exterior. The filtering layer is e.g. a felt or non woven fabric and is at least partially covered by the bottom 21 of the bag. The filtering layer preferably forms a closed pocket 22 opposite the filling valve 18. Alternatively the filtering layer surrounds the filling valve tube. <IMAGE>
