Abstract: A method for operating a sealing station of a packaging machine, wherein the method may include one or more of the following steps: filling a packing volume of a package with a gas to create a desired atmosphere to a preset gassing target pressure for a finished package, wherein the packaging volume may be defined by a lower and an upper packaging material; discharging a partial amount of the gas introduced into the packaging volume from the packaging volume into a collection volume while retaining the packaging volume generated by the preceding filling, which reduces the pressure within the packaging volume; and reducing the packaging volume by moving the upper packaging material to an end position that corresponds to a desired appearance such that the pressure inside the package increases again to near the gassing target pressure. A sealing station that performs this method is also described.

Abstract: The disclosure refers to a packaging device for manufacturing a packaging for a foodstuff. In particular, the packaging may include a trough-shaped lower packaging part and a top film which can be sealed together along their edges by means of a sealing tool of the packaging device. In order to improve a packaging device completely without evacuation or by evacuation in a simple and inexpensive manner with only a slight negative pressure in such a way that sufficient vapor purging is possible and at the same time cooling of the foodstuff before sealing or excessive degassing of the foodstuff does not take place, vapor can be introduced under pressure between the lower packaging part and the top film at at least one vapor entry point before sealing and can be released into the surrounding atmosphere at an outlet point from the packaging.
