Sheet and Film Industry

A chiller should be selected according to cooling capacity, roll load, water conditions, ambient temperature, and line speed. A water cooled screw chiller for film lines is suitable for large and continuous cooling demand.

Optical films are sensitive to roller marks, haze, and gloss variation. Stable optical film roller temperature control helps improve surface consistency during coating, extrusion, and calendaring.

Cooling stability affects separator shrinkage, wrinkles, and pore structure. A large flow water temperature controller for battery separator lines helps maintain uniform cooling across the process width.

BOPP and BOPET lines need separate zones because extrusion, casting, stretching, and heat setting have different thermal requirements. Multi-zone film temperature control helps keep each process stage stable.

Cast film clarity is affected by unstable chill roll temperature and melt cooling speed. An industrial chiller for cast film cooling helps keep cooling conditions consistent and improves surface appearance.

Uneven film thickness is often caused by temperature differences in the die, roll, or barrel. A sheet and film temperature control unit helps stabilize the thermal field and reduce gauge bands.
