Masterbatch suppliers are contributing to the sustainability drive in plastics with developments such as colour products that have carriers made from post-consumer recyclate. Peter Mapleston finds out what’s new

Color and Additives at Avient, says: “Increasingly, major consumer goods companies are actively defin- ing sustainability goals of up to 100% post-consumer recycled packaging.
