Designed for COEX- castfoil production with additional coating unit.
The extrusion part of the line has 2 extruders; the coating unit has 1
extruder. Processing of thermo plastics in a temperature range of
90-300°C.
Different combinations of production are possible:
- main unit (CoEx) with coating
- main extruder (CoEx) without coating
- coating processing over winding unit on an existing base film
For production in the different described combinations you can lock
the not necessary equipment parts.
POSSIBLE LAYER STRUCTURES:
Main extruder:
- Mono film if necessary with tensilized film
- 3- layer film (A-B-A) if necessary with tensilized film
