Trends for sequential oriented BOPET Films Special films with Coextrusion „ Cost reduction by using only pigments in the skin layers for standard films, matt films, hot stamp films, … „ Better optical properties (high transparent/ low haze films) by the use a low amount of masterbatch (only skin layers pigmented) „ One side smooth surface (for metallization or ceramic coating) „ Multi layer configuration for improved barrier properties „ Hot sealing films e.g. separation of pigmentation and sealing material possible „ Multi layer structure to improve further processing of the film e.g. PE – Lamination Special Film by Inline Coating „ Improved adhesion of metal during metallization „ Improved adhesion of ink during printing „ Improved adhesion for subsequent polyolefin lamination „ Improved release properties of the film „ Improved barrier properties for gases and moisture e.g. as substitution of aluminum layer plastic film (microwave capability, …) © Brückner

Trends for simultaneous oriented BOPET Films Ultra-thin Films for Capacitors „ Thickness down to 0,5 µm „ High Stiffness „ Good Runnability Tensilized Films for technical applications „ Thickness Range 4 – 12 µm „ Ultra High Modulus „ Good Runnability Thick Films for optical applications „ Thickness up to 250 µm „ Excellent optical properties „ Very low shrinkage values „ Isotropic mechanical properties „ Low Bowing © Brückner
