  • Publication number: 20230399159
    Abstract: A packaging container made of a plastic film. The packaging container includes a receptacle space for goods arranged between a front wall and a rear wall, an upper and a lower traverse seam which closes the packaging container on an upper and a lower end, respectively, connecting seams running between the upper and lower traverse seams, a film strip fastened to an internal side of the front wall via the connecting seams, a longitudinal channel formed by the film strip, the front wall and the connecting seams, and an engagement element arranged in the longitudinal channel. The engagement element is arranged transversely to a longitudinal extent of the longitudinal channel, and in a cross section above the film strip, to permit an engagement in the longitudinal extent of the longitudinal channel between the front wall and the film strip.

  • Patent number: 11787615
    Abstract: The invention relates to a bag (3) having a filling space for bulk material, which filling space is delimited by a lower base (4), a circumferential wall (6), and an upper filling space closure (8) facing away from the lower base (4). The bag has at least one tear-open strip (10) for exposing an opening area (12) of the bag (2), which is delimited by an upper weakening line (14) and a lower weakening line (16), wherein both weakening lines (14, 16) extent parallel to the upper filling space closure (8), and the upper weakening line (14) is positioned between the upper filling space closure (8) and the lower weakening line (16). The bag (2) has a longitudinal seam (18) extending transversely with respect to the upper filling space closure (8). The upper and the lower weakening line (14, 16) begin in the area of the longitudinal seam (18).

  • Patent number: 11214407
    Abstract: The invention relates to a ventilatable valve bag with a wall material (4) comprising at least one gas-permeable inner layer (6) that is impermeable to a filler material and at least one gas-impermeable outer layer (8) as well as two closing sides (10), a first closing side (10) being formed by closing the valve bag (2) and a second closing side (10) being arranged opposite the first closing side (10). An intermediate space (14) is formed between a part of the inner layer (6) defining an inner space (12) of the bag and the outer layer (8), and at least one ventilation channel (18) leading out of a wall material edge section (16) is arranged on at least one closing side (10) of the valve bag (2), between the inner layer (6) and the outer layer (8) of a wall material region, such that the intermediate space (14) can be ventilated to the surroundings.
