ABSTRACT:
In a composite bag comprising an outer bag and an inner bag which is secured thereto by adhesive, the outer bag is provided with a cross-bottom folded closure at least at one end where no filling valve is provided. Adjacent said one end of the outer bag, the inner bag is closed by a weld seam and folded back on itself and secured in position so that, in a flattened condition of the composite bag when the cross-bottom folded closure lies snug against the bag body, the inner bag extends no further than the centre line of the cross-bottom closure.
