Abstract:
1. A packaging container for bulk materials the packaging container comprising: a plastic film having at least one container wall enclosing the bulk material; a multilayer venting region extending in a longitudinal direction of the at least one container and comprising: exactly one shielding element inside the venting region associated with the outer opening in the joining seam for deliberate diversion of at least a partial flow of the air flow passing through the venting region, wherein the shielding element and the outer opening are arranged in at least an end region of the venting region, wherein the shielding element ends directly at a transverse seam limiting the venting region and separates the inner and outer openings from each other, and wherein the venting region has only one chamber, in which the exactly one shielding element has a length that is between 10% and 50% of the overall length of the venting region and in which the inner layer includes the surface region through which at least further partial flow can pass and which are not in the region of the shielding element, so that the partial flow, which has been diverted at the shielding element, is merged with the at least further partial flow, which has passed through surface portions of the inner layer which are not in the region of the shielding element.
