BOPP Film Production Line Chill Roller with Double Shell Construction and High Efficiency Heat Exchange

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 channel is designed to improve the heat conversion efficiency and temperature control accuracy. After replacing with this kind of technically updated chill roller, the casting efficiency will rise by 20%-30%.

• Variable diameter alternating spiral flow channel
• Surface temperature precision ±0.5ºC
• High efficiency heat exchange technology performance
• High precision dynamic balancing correction
• High quality mirror face processing
• Anti-corrosion treatment of spiral flow channel
• Roller cylindricity, concentricity both ≤0.005mm
• Roller surface hard chromium plated
• Roller surface treatment: mirror polished, super finishing mirror, matt, mist and anti adhesive surface
• Overall deformation: < 0.05 mm at full load

Casting system is a step of vital importance in film stretching line. The finish film quality after stretching will be finally based on master precision 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.

We Huatao Group located in Shijiazhuang city, Hebei province, China which specialized in supply roller to BOPET line, BOPP line, CPP line, Slitter, Metalizer machine and laminating machine.

We warmly welcome all friends and customers to work together to create a bright future.
