Adding Oppera™ modifier to the middle layer of multilayer bi-oriented polypropylene (BOPP) films can improve moisture resistance up to 50% and oxygen barrier performance up to 70%. Food packed with Oppera modifier-based BOPP films can stay fresh longer for extended shelf life compared with unmodified film.
In addition to outstanding barrier protection, Oppera modifiers in a BOPP film formulation can create simplified and cost-effective film structures. The optimal addition level of the Oppera modifiers depend on the intended end use and required performance.
