I have been in quite a puzzle for while. That is while i am looking for a profesional and experienced opinion from you.
The puzzle is which extrusion is for PET produces better sheet for thermoforming - single screw or twin screw extrsuion lines?
I am looking for the pros and cons of both types of PET extrusion (single screws and twin screws).

I will be very grateful to hear your opinion beucase i have read many books and still cannot decide which is the better decisionfor the moment.

Thank you!
