Sustainable compounding
Blown film manufacturer in Benin switches from polyethylene-based to biodegradable products with help from Coperion

Stuttgart, July 2019 — Coperion has enabled Benin-based blown film manufacturer Asahel Benin Sarl. to produce sustainable, bio-based plastic films in the future by delivering a complete compounding system and sharing the corresponding process engineering expertise. The system includes a ZSK 26 Mc18 twin screw extruder, four highly accurate feeders from Coperion K-Tron, as well as a water bath, an air wipe and a strand pelletizer from Coperion Pelletizing Technology. Before plastic bags and packaging were banned in Benin in July of 2018, this west African manufacturer had made its plastic films using polyethylene (PE). The new law forced the company to completely convert its production. Following a successful test and training phase at Coperion’s Stuttgart test lab, Asahel Benin Sarl. will produce biodegradable compounds in its home country with the aid of the ZSK twin screw extruder, and will then further process these on its existing blown film machinery into biodegradable bags and packaging materials...
