Unlocking the Power of Sustainable Packaging, Recycle the Polymer Film Lid Part III

Plastic films used in food packaging are made of multiple layers of polymers, each with its unique properties. As a result, up to 40% of pristine film is discarded as industrial waste during the manufacturing process. However, researchers from the University of Wisconsin-Madison, Department of Energy, and Amcor Flexibles have developed a process called STRAP, which uses different solvent washes to dissolve and recover the pure polymers from the discarded film.
