Abstract (en)
[origin: CA3064489A1] 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.
