Decisions about those investigations are expected in mid- to late-December. Having another qualified substrate ready for use is wise.
Metallized films (OPP, PET, nylon, and cast OPP) are manufactured by means of high-speed vapor deposition that offers converters and end users proven foil replacement solutions for their laminations. In this overview article, we’ll explain the performance advantages of thin-gauge metallized OPP and PET packaging films and review the challenges and considerations involved in exploring a foil replacement.
