Abstract

A method for the production and filling of packaging includes unwinding flattened tubular film material from a roll along a primary axis of symmetry thereof, providing the tubular film material via a welding and separating process with a first lateral welding seam perpendicular relative to the axis, and separating the tubular film material along a separation line to provide a hose section. The hose section open at one side is filled, and the still open other side of the hose section is provided with a second lateral welding seam. Two subsequent separation lines are inserted in the hose section at a distance that is less than the distance between the two edges of the hose.
