Abstract (en)

[origin: EP0176851A2] The bag has a closed bottom (2) and a top end (4), which is closed on both sides of a filling opening (19), and a closure flap (8) which extends beyond the top end (4) in the region of the filling opening (19) and can be folded over the front side of the bag (1) about a folding line (5) coinciding with the top end (4). There is an application of adhesive on the closure flap (8) on its inside surface and/or on the associated counter-surface on the front side of the bag (1). For secure and dust-tight closure of the bag, in the case of multi-layer bags the outer layer of the closure flap (8) is to have edge strips (36, 37, 38) which project over the inner layer(s) both in the longitudinal direction and in the transverse direction of the bag, or a cover sheet (9) is to be attached on the rear side of the bag (1), which cover sheet is part of the closure flap (8) and has edge strips (10, 11, 12) which project over the inner layer(s) of the closure flap (8) both in the longitudinal direction and in the transverse direction of the bag. The edge strips (10, 11, 37, 38) extending in the longitudinal direction of the bag each have on their inner surface adhesive beads (13, 14; 33, 34) which extend over the folding line (5) and which are combined with at least one further adhesive bead (15, 30) on the edge strip (12, 36) extending in the transverse direction of the bag or on the closure flap (8) to form a continuous adhesive bead. <IMAGE>
