Abstract (en)
[origin: WO2018060275A1] The invention relates to a valve bag, in particular a cross-bottom valve bag, comprising a first wall and a second wall, which are joined to each other by means of side edges or side folds and by means of bottoms and which bound a bag interior, comprising a valve, which is arranged in one of the bottoms and via which the bag interior can be filled with a filling material, and comprising venting openings in the first and/or in the second wall for venting the bag interior. At least one channel is provided on the outside of at least one wall, which channel covers the venting openings and is formed at least by two parallel fastening strips and by a cover strip, the cover strip likewise comprising venting openings. The shortest path between the parallel fastening strips along the cover strip is longer than the shortest path along the at least one wall, or the cover strip and/or the parallel fastening strips consist of stretchable material.
