• Cast film rollers are widely applicable to a variety of thermoplastic film materials. • PE and PP are the most typical and suitable material types. • Materials such as PET and PVC place higher demands on cast film rollers, but are still suitable. • Multilayer composite films place even stricter performance requirements on cast film rollers.

An industrial casting film roller is a high-precision industrial roller used in the casting process to achieve cooling, shaping, and surface replication by contacting molten or semi-molten material.

• The smoother the roller surface, the smoother the film surface • Microscopic defects on the roller surface will also result in corresponding defects on the film surface Therefore, the surface condition of the cast film roller is not an "indirect influence," but one of the core factors directly determining the surface quality of the film.
