Coperion GmbH is implementing a closed-loop concept for the production of flexible multi-layer film. Recycling multi-layer film has long posed a challenge since such films can only be reclaimed in very complicated ways and not without residues. Now, however, Coperion has developed a closed-loop approach solution in which up to 100 percent of multi-layer film production waste can be re-processed and fed back into the production process in a closed-loop. For a concrete project Coperion will deliver a recycling system, including bulk material handling, high-accuracy feeding from Coperion K-Tron, and the heart of the system, a ZSK Mc18 twin screw extruder.
