In the context of mechanical recycling of post-consumer plastic waste, food-contact is a rather complicated target, both from a technical and regulatory point of view. Versalis (Eni) has launched a new product for food packaging called Versalis Revive® PS Air F, made of 75 % recycled polystyrene obtained from domestic separate waste collection. With this material, through an important collaborative effort that involved all the players in the food supply chain coordinated by Versalis (Eni), an innovative fully recyclable R-XPS food tray was developed, made with an internal layer containing Versalis Revive® PS Air F and two external layers of virgin polystyrene. This structure, called A-B-A functional barrier, guarantees food-contact in compliance with European Regulations (EC) No. 282/2008 and (EU) No. 10/2011.
