Thermoforming extrusion line

sheetfoodcoating

Sheet extrusion lines based around the Gneuss OMNI Recycling Systems are in operation worldwide in the manufacture of PET sheet for thermoforming (see also PET bottle recycling). The applications range from monolayer sheet from 100 % post consumer bottle flake for food contact applications to liquid coated and laminated sheet Technical options: Gravimetric multiple component dosing feeders Coextrusion (MRS, single screw extruder) Foam sheet Sheet lamination Coating for antiblock /antistatic Thickness measurement with optional automatic die lip adjustment of the sheet die Sheet quality monitoring system Stress Analyser and much more… Typical applications are throughput rates from 350 kg/h to 2.000 kg/h, sheet widths of up to 2.000 mm and sheet thicknesses between 0,15 and 2 mm. In addition to PET bottle flake and virgin material (pellets), edge trim and skeletal waste regrind from PET, GAG and PET sheet with PE lamination are often added. Due to the especially gentle direct processing without pre-drying, crystallising or frictional heat, materials with widely different melting points can be processed directly. Advantages of the Gneuss thermoforming sheet lines: High transparency and gloss, low yellowness High toughness and impact resistance, low brittleness Very good thermoformability due to excellent molecular weight distribution Very homogeneous distributive mixing, excellent melt homogeneity Letter of Non Objection (LNO) from the FDA for up to 100 % recycled content, EFSA, direct food contact for both monolayer and co-extruded sheet
