Film blowing and take-off unit

The film blowing unit simultaneously blows up, cools, takes off, and winds up your extruded blown films. 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.
