17 Aug 2020 --- Syntegon, Taghleef Industries and Polifilm have joined forces to develop an aroma-proof polypropylene (PP) monomaterial solution for coffee packaging. The cooperative project yields the “best aroma and product protection combined with 100 percent recyclability,” film extrusion specialist Polifilm declares. The joint move provides a closed-loop solution to conventional coffee packaging that uses aluminum-containing composite, which is a “classic example of poorly recyclable solutions.”
