Tubular Bag Packaging and Method for Producing Such Tubular Bag Packaging

A method for producing a tubular bag packaging for a bar-shaped food product, wherein the tubular bag packaging has a longitudinal extension in a longitudinal direction and a transverse extension in a transverse direction perpendicular to said longitudinal direction;

• wherein the tubular bag packaging comprises a film with first and second longitudinal edges extending in said longitudinal direction;
• said film comprising a first seal section extending along said first longitudinal edge and a flap section adjoining said second longitudinal edge, wherein said flap section has a second seal section extending along said second longitudinal edge;
• said method comprising the steps of:
• sealing said first and second seal sections by producing a continuous back seam, extending in said longitudinal direction, by interposing said first and second seal sections between sealing rollers and closing said film at said first and second seal sections with said sealing rollers, wherein said back seam is embodied as a fold-over seam;
• sealing said film at transverse edges by a transverse seam, respectively, said transverse seams extending in said transverse direction, wherein said back seam has an end face edge adjoining said transverse seams, respectively;
• providing said flap section with a linear separation cut as a tearing aid on at least one of said end face edges so as to extend away from said end face edge at least approximately parallel to said longitudinal direction;
• generating a pressure deformation line that extends at least approximately parallel to said longitudinal direction by a first profiling that is provided on a first one of said sealing rollers.
