TZ-machinery explains how a PET co-rotating twin-screw extruder works — screw elements, six processing stages, vacuum degassing and how to control PET degradation in sheet extrusion.
ABA PET three-layer co-extrusion line case study: a Thai packaging plant upgraded to an 85 twin-screw plus 75 single-screw configuration for high-clarity sheet.
Recycled PET sheet yellowing and brittleness traced to their root causes, with twin screw extrusion settings and masterbatch dosages to fix color and toughness.
ABA PET sheet extrusion line case study: how a Kosovo recycling plant runs 100% rPET flakes into food-grade PET trays with 4-station thermoforming.
What to check before sourcing a PET sheet line to Colombia, Chile or Peru: 220/380/440V 60Hz supply, up to 80% rPET core, 300-1,000 kg/h output, port documents.
An ABA PET co-extrusion sheet line runs recycled rPET in a 70-80% core between two virgin PET skins, cutting resin cost while keeping food-contact clarity.
