Abstract (en)
In a web (4) of bags (8) which are interconnected via a first wall weakening (6) and are made of plastic film material, each bag in the web comprises a tubular film part which is provided, on two longitudinal sides situated opposite one another, with concertina folds (10). Each bag is provided, in the region of one end (21), with a first transverse bottom seem (22). The bag is provided, in the region of both ends (20, 21), with oblique concertina-fold part seams. Each bag is provided, in the region of the oblique concertina-fold part seams (24, 24' and 26, 26', respectively), with a second wall weakening (30), which extends, in the transverse direction of the bag, from the outer longitudinal concertina-fold edges (14) on one of the two longitudinal sides of the bag over at least part of the width of the bag. The tear-open strip is formed as a result. <IMAGE>
