HIGH TRANSPARENCY ZeonorFilm exhibits high transparency (92% light transmittance) and excellent turbidity (haze value <0.1%), for enhanced brightness. INERT SURFACE ZeonorFilm is manufactured from Zeon's cyclo olefin polymer (COP). COP is known for its excellent optical properties and also for being a high-purity resin. ZeonorFilm has an inert surface which makes it ideal for sensitive bio-diagnostic devices.
