Abstract:
1. A tubular bag packaging for bar-shaped food products, 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; the tubular bag packaging comprising: 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 film sealed at said first and second seal sections to form a continuous back seam extending in said longitudinal direction, wherein said back seam is embodied as a fold-over seam; said film sealed at transverse edges by a transverse seam, respectively, said transverse seams extending in said transverse direction; said back seam having an end face edge adjoining said transverse seams, respectively; wherein said flap section has a linear separation cut as a tearing aid for producing a tear in said film, wherein said linear separation cut is disposed on at least one of said end face edges and extends away from said end face edge at least approximately parallel to said longitudinal direction; wherein said film in the area of said second seal section of said flap section provided with said linear separating cut comprises a pressure deformation line that is generated by a linear plastic cold deformation of said film, wherein said film has a deformed weakened cross-section along said pressure deformation line but said film is not completely separated along said pressure deformation line, and wherein said pressure deformation line extends at least approximately parallel to said longitudinal direction.
