In order to achieve the object of providing a process of this kind with which bags with integrated handles can be made in the most simple and cost-effective manner, after forming of the first transverse weld seam as head seam, the tubular film web is advanced intermittently and a further transverse weld seam as closure seam is formed with the same welding tool. The handle hole is then provided between these two weld seams.
