04 Dec 2018 --- Petcore Europe and Plastics Recyclers Europe (PRE) have published guidelines for manufacturers and suppliers to produce fully recyclable PET thermoformed trays. The report hopes to extend the success of PET bottles’ high recycling rates in Europe to PET trays, as well as increase the use of recyclate. PET-based trays already contain an average of 55 percent recycled plastics, but full circularity is the goal.
