Coperion is offering a closed-loop recycling process solution for 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.
Multi-layer film waste resulting during the production process is shredded as a first step before it is fed into the ZSK extruder via pneumatic conveying and highly accurate feeding from Coperion K-Tron. There, the material is homogenized and devolatilized with very high intensity in the co-rotating ZSK Mc1? twin screw extruder. Within the extruder, dispersion and devolatilization performance are crucial to end product quality — with gentle product handling and very good mixing behaviour even at very high throughput rates, thus achieving consistently high product quality.
