Abstract:
A tubular bag packaging for bar-shaped food products is made of a film with first and second longitudinal edges. The film has a first seal section at the first longitudinal edge. A flap section at the second longitudinal edge has a second seal section along the second longitudinal edge. The film is closed at the seal sections by forming a continuous back seam in longitudinal direction as a fold-over seam. The film is sealed at transverse edges by transverse seams. The back seam has end face edges adjoining the transverse seams. The flap section has a linear separation cut as a tearing aid disposed on at least one of the end face edges and extending away from the end face edge in longitudinal direction. The film in the area of the second seal section with linear separating cut has a pressure deformation line that extends in longitudinal direction.
