ABSTRACT:
A packaging container has walls made of film defining an interior of the packaging container. At least a first one of the walls has two wall parts that overlap one another forming an inwardly positioned overlapping strip and an outwardly positioned overlapping strip and providing an intermediately positioned venting passage. The overlapping strips are connected to one another by a securing seam that extends along an edge of the inwardly positioned overlapping strip. The venting passage communicates through inner openings with the interior and through outer openings with the ambient. The outwardly positioned overlapping strip has no openings. At least one filter is provided with the outer openings of the venting passage and is positioned underneath the outwardly positioned overlapping strip in a flat arrangement.
