  • there are flexible, full-surface, space-forming packaging in the form of bag packaging such as bottom bag, flat bag, sealed edge bag, space bag, stable bag or bag.
  • the bag in this case forms a filling space in which at least one product in the closed state of the bag is completely enveloped by the bag.
  • a closure seam e.g. formed a sealed seam, such as a hot or cold sealing seam, weld or adhesive seam.
  • flat bags may have three or four sealing seams corresponding to three or four side edges, depending on the manner of manufacture.
  • a tubular bag may include an upper and an opposing lower transverse seam or an upper and a lower transverse seam and a hull seam, such as an overlapping or folded hull seam.
  • the tearing process usually takes place along a tear line, along which the package is separated at least in sections into at least two parts and which leads at least in sections through the filling space of the packaging.
  • the contents can then be removed by the resulting opening in the package in any way.
  • the tear line can lead controlled or uncontrolled through the packaging.
  • weakening lines in the bag wall which can be designed, for example, as cut, partial cut lines, perforations or the like.
  • the notches are also so small that the user does not perceive the marking point on the bag and tries to open it at another, unconfigured point of the bag, which can also cause the bag to tear suddenly and suddenly.
