Multi-Layer Film Recycling - Innovative Process Solution
To further cultivate the circular economy, recycling is increasingly becoming an essential part of plastics processing and production. However, the processes involved in handling and recycling waste material can be fairly complex and may pose some challenges due to the often inhomogeneous characteristics of the material. Therefore, plastics manufacturers seek reliable solutions to meet these challenges and handle their industrial waste in an efficient way.
To support customers with these challenging recycling tasks, 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 behavior even at very high throughput rates, thus achieving consistently high product quality.
