11.2.2.2 Calibration and burn-in sealing bars
During initial sealing bar heat-up to approx. 200°C – 250°C (392°F – 482°F), the material undergoes a
one-off resistance variation, also known as the burn-in effect.
NOTICE
If sealing bars with new sealing wires have been installed in the machine, the following proc-
esses have to be carried out one after the other:
Calibration sealing bars – Burn-in sealing bars – Allow sealing bars to cool down – Calibration
sealing bars.
If sealing bars with previously burnt-in sealing wires are installed in the machine, only Calibration seal-
ing bars must be carried out.
These processes are carried out in the step 1. Read section 9.8.1.1 Mask 152: Calibration sealing bars.
NOTICE
Only use sealing wires and sealing bars specified by the manufacturer and stated in the spare
parts list!
