Cast film is a non stretch, non oriented flat extruded film produced by melt casting and rapid cooling. There are two methods: single-layer casting and multi-layer co extrusion casting. Compared with blown film, its characteristics are fast production speed, high yield, and excellent transparency, gloss, and thickness uniformity of the film.CollinThe extrusion line for cast film and sheet has high flexibility. Can produce20μm-5000μmThick, up to1000 mmWide films and sheets are suitable for the production needs of the vast majority of laboratory trials.

The film casting machine is used in conjunction with an extruder and a die head. After the polymer material is plasticized and melted by the extruder, it enters the die head for molding. It is cooled and formed by the casting roll, and finally pulled to the winding system by the traction roll, completing the entire casting process.CollinThe advantage of a cast film machine lies in a complete set of cast film machines, including extruders-Mold head-The casting units all come fromCollinManufacturing without any other purchased equipment ensures the compatibility and stability of the system. In addition, other optional items can be provided according to customer requirements, such as trimming devices, film defect detection systems, anti-static systems, corona treatment and other additional functional options, to meet special process requirements.
