The bubble diameter and film thickness can be adjusted precisely. The film blowing and take-off unit can be controlled manually or through the PC (via CAN bus).
Depending on the material, common blowing ratios are 1 : 2 up to 1 : 4. These can be controlled automatically with an optional film width control.
In combination with the Film Quality Analyzer, the purity of the film can be checked continuously during take off.
