Cast Film Meaning

Cast film is a type of plastic film produced through a casting process, where molten resin is extruded and rapidly cooled on a chill roll. Unlike blown film, cast film offers excellent clarity, uniform thickness, and high flexibility. In the packaging industry, cast film is widely used for multilayer applications because it provides consistent quality and excellent sealing performance.

One of the main advantages of cast film production is the high line speed. Cast film lines typically run faster than blown film lines, making them ideal for high-volume packaging film manufacturing. The faster cooling process not only improves productivity but also ensures better film flatness and mechanical properties.
