<p>The bag (1) has an upper edge (1f) closed by a sealed welding seam after filling the bag, and a bottom that is continuously formed by sealing. The bottom is folded and fixed to a wall of the bag. A folded bottom part is fixed with complementary temporary coupling units (2, 3) e.g. hermaphrodite type self-gripping elements. The bottom comprises a discharge opening forming arrangement in a median part. The arrangement forms a discharge opening after turning the bag and separating the folded bottom part, such that the upper edge forms the bottom after turning the bag.</p> |
