A method for producing a package made of a flexible material, in which a single flexible material web is folded longitudinally, and superposed layers of the folded material web are firmly bonded to one another. At least one section of the material web is constructed as a tubular piece, and individual gusset edges of the material web are at least partly cut. Tubular pieces of a predetermined length are cut from the material web, in the area of at least one opening of the tubular piece. The outer layers are turned over, and layers of the material located therebetween are shortened. A sealing element is applied to the ends of the shortened layers and brought in contact with one of the outer layers. The shortened ends are closed after re-turning the outer layers, and fixed to a respective outer layer. Predefined regions of superposed layers of the tubular piece are then firmly bonded to one another.
