In one step from crushed PET bottles to a high valued packaging film

Flat film extrusion: The production of PET flat films on highperformance flat film extrusion lines using recycled waste products (r-RET) provides high productivity along with high overall efficiency. State of the art filtration technology ensures the required product quality even at high R-PET raw material usage. The KREYENBORG GROUP provides modular discharge units consisting of melt pumps and screen changers. Here, the high demands of film extrusion on the homogeneous melt quality and pressure constancy in the process are especially considered. In practice KREYENBORGs patented piston screen changers with self cleaning device (so called Backflush Screen Changers) type K-SWE-4K-75/RS convince by their easy operation and high reliability.

Result: Proven technology for the extrusion process combined with the latest filtration technology from KREYENBORG provides an innovative master plan for producing A-PET and R-PET flat films.
