In February 2020, we participated in an international tender for the award of this project. Socopet was the winner among the 15 participants. The project specifications envisaged replacing the entire production of PVC pill containers with the much more recyclable PET, however, going to create containers with a wall thickness suitable to offer a correct and sufficient barrier to moisture, the true enemy of those gel pills. We have therefore created the actual 3 references (250, 120 and 70 ml) with two different colors.
