RecyClass commissioned an independent laboratory to test the compatibility of vinyl alcohol (EVOH) barrier in polypropylene (PP) rigid packaging with the state-of-art recycling process. EVOH which is combined with a polypropylene-grafted maleic anhydride (PP-g-MAH, with MAH > 0.1%) tie layer does not jeopardize the recyclability of a package, the findings demonstrated. Testing was performed on
