A bag comprising several side panels, a bottom panel and a top panel with a filling opening is made by stitching together opaque fabric webs forming the aforementioned panels. The bag includes seams which are formed by turning up edge regions of the fabric webs and in which at least one sealing strip of material is inserted and stitched to the fabric webs. To obtain increased sealing tightness of the stitching, the strips of material are of yielding construction and have an isotropic structure. The side panels of the bag may be constituted by a tubular one-piece fabric portion.
