Chill Roller for BOPP/BOPET film production line
Chill roller is widely used in master casting forming of BOPP, BOPET, BOPA, BOPS, BOPI biaxial oriented stretching line and longitudinal stretching line. The chill roller with special inner circulation channle is designed to improve the heat conversion efficiency and temperature control accuracy. After replacing with this kind of technically updated chill roller, the casting effeciency will rise by 20%-30%.
Casting system is a step of of vital importance in film stretching line. The finish film quality after stretching will be finally based on master precsion of casting system. This chill roller has already been used a lot in high level stretching line imported from Europe and its performance in practical application obtains unanimous approval and favorable comment from customers.
