BOPP Film Production Line Chill Roller Double Shell Construction

Chill Roller Basis Information

The chill roll is a water-cooled roll that cools the hot melt film.

Chill roller is widely used in master casting forming of BOPP, BOPET, BOPA, BOPS, BOPI biaxial oriented stretching line and longitudinal stretching line. It plays a crucial role in the cooling and solidification of the molten polymer as it is transformed into a thin film. The chill roller helps to ensure uniform thickness, flatness, and quality of the films. 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%.

Chill Roller Advantage

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.
