Beschreibung
Zusammenfassung:	A packaging machine, comprising a control unit, at least one measurement device and a plurality of work units for different processes. One of the work units is designed as a sealing station which comprises at least one moisture sensor designed as the measurement device which is functionally connected to the control unit and is designed to detect moisture within the sealing station as a time-dependent measured variable during a program sequence of the sealing station. The program sequence may comprise an evacuation process, wherein the control unit is designed to calculate a rate of change in the moisture during the evacuation process of the sealing station. The control unit may abort the evacuation process performed on the sealing station, based on the rate of change, before reaching a target vacuum pressure within the sealing station, immediately or after a specified delay time elapses.
