Abstract: A bag has front and back face panels having upright longitudinally extending side edges and transversely extending upper and lower edges. First and second gusset panels each have transversely extending upper and lower edges and upright longitudinal outer edges connected to the longitudinal edges of the face panels. A reclosable fastener strip extends continuously and transversely along the first gusset panel and inward along each of the face panels from the first gusset panel along part of a transverse width of the face panels. Thus opening of the fastener and folding out of the first gusset panel forms a spout on the bag. A separate generally rectangular floor panel is joined at its outer edge by thermal welds to the lower edges of the face panels and of the gusset panels.

Abstract: A longitudinal method for producing a side-gusseted bag includes providing an incision extending in a transverse direction in a bag film for each side-gusseted bag in such a way that, in the case of a subsequently formed side-gusseted tube, the incision extends over both side gussets and a first front wall that is situated between the side gussets. Proceeding from the incision, the first front wall, together with the corresponding parts of the side gussets, is folded back, on which a separate film section is placed and fastened in the folded-open region. The folded-over section is folded back in such a way that all connecting seams of the separate film section extend in parallel to each other in the transverse direction.
