Perfect for PET Sheet Lines!
Due to PET’s susceptibility to hydrolysis, pre-drying within the extruder is essential. Single-screw extruders struggle with this drying process, making our CTM co-rotating twin-screw extruder the ideal choice. It significantly improves both PET sheet quality and production efficiency.
