These flip-top closures are manufactured on the basis of RE Plano's PP product PLANOPROP® which is made from post-consumer recycling streams (PCR).
RE Plano and ExxonMobil collaborated to produce a high quality PCR compound, and the caps were produced using Kutterer Mauer AG molding expertise. The improvement of mechanical properties of the flip-top cap was enabled by using Vistamaxx™ performance polymers. Vistamaxx™ has primarily impact through strength improvement for applications that require tighter drop tests (drop height and deflection angle) and living hinges.
