Extrusion International 2-2019

42 Extrusion International 2/2019 RECYCLING OF PET Ultra-fine microperforation sets new standards in melt filtration With unprecedented filtration fineness of 60 µm, Ettlinger’s ECO melt filters will in the future make it easier to treat recycled material for the film, packaging tape and fiber industry and help plastics recyclers remove challenging contaminants like paints, silicones, barrier materials, cross-linked fractions and gels from the melt. In particular, the new filter screens will enable cost-efficient conversion of post-consumer PET bottle flake and fines, which generally occur in large amounts, into recycled material with excellent usage properties Thanks to the even smaller 60 µm screen size which is now available for Ettlinger’s ECO series, these filters are ideal whenever 100%PET bottle flake is used in thermoform sheets, packaging tape or staple fiber plants (© Ettlinger)
