Polystyrene (PS) has a long and successful history in the world of packaging. It has been the gold standard for rigid thermoformed food and medical packaging applications.

In episode two, the C.A.P. Pack has assembled to talk about the history of polystyrene, the characteristics that make it so extraordinary, and why so many people and organizations have decided that it needs to go. They also dive into the extraordinary challenges of finding an acceptable PS replacement, and how a 15-year journey led to the development of XPP — the “unicorn material” that can finally replace polystyrene.
