Greenflex FL 55 is an ethylene vinyl acetate copolymer (EVA) for extrusion/co-extrusion blown and cast film.
Films produced with Greenflex FL 55 show a low fish eyes content, high elasticity, good optical properties, good sealability at low temperatures.
Greenflex FL 55 is recommended for the production of co-extrusion film, lamination film, stretch film, barrier film for food packaging and all those aplications where the typical purity of film grades is required.
