Bag has elastically stretchable border section which is separable and fastened on second section of bag wall, and fastened in relaxed state and welded on

摘要

The bag has a sidewall (2) with a border section (4) which at least in sections is elastically stretchable in the circumferential direction. The stretchable border section is separable and is fastened on a second section (3) of the bag wall. The stretchable border section is fastened in a relaxed state and is welded on. At least a part of the stretchable border section has a circumferential length (u) which for the forming of a stretching reserve (A) is shorter than the circumferential length (U) of the adjacent second section.
