Abstract: The invention relates to a pressure relief valve, comprising a base body, which is covered by a valve membrane. The base body which is located on the inner face of a packaging container, permits the escape of excess pressure from the packaging container into the atmosphere by means of passages and perforations that are configured in the wall of the packaging material. The inventive pressure relief valve thus responds particularly well. i.e. allowing particularly low opening pressures, by means of the special configuration of its base area.

Abstract: A tube-forming apparatus in a bag-forming, filling, and sealing machine has a longitudinal seam heat-sealing device for connecting edge regions of the packing material belt that are placed against each other inside surface to inside surface. In order to achieve a sufficient sealing temperature in a short time, a heating body that is embodied in a lamella-like fashion protrudes like a tongue between the edge regions. In order to aid the heating body, similar heating bodies rest against the outside of the edge regions. The heating bodies have a U-shaped electric resistance wire with elongated legs which is embedded in a longitudinally folded casing made of a thin, temperature-proof woven cloth.
