The present invention discloses a sealing system for sealing together at least a pair of flexible pouch material layers. The sealing station can have a first sealing bar, a second sealing bar and a drive system that is in contact with the first sealing bar. The drive system is operable to move the first sealing bar between an open position and a closed position such that the first sealing bar can apply a predefined pressure on the flexible pouch material layers when positioned or located between the sealing bars. A pressure sensor is also included and in communication with the drive system, the pressure sensor operable to detect if the drive system applies less or too much pressure than the predefined pressure on the flexible pouch material layers located between the first and second sealing bars.
