Calendering is a manufacturing process that involves passing soft and hot plastic between successive cylinders to form a continuous plastic film. This process ensures a uniform thickness and a clean surface appearance.

At CIFRA, the plastic used in calenders comes from a formulation prepared according to customer wishes or a mixture of recycled materials. A graining cylinder can be used to personalize the surface aspects. The resulting film is then rolled up or cut to the widths desired. The film can also be doubled with other complex materials or coated, to associate the qualities of other films.
