PET flex waste is collected from various sources including industrial waste and recycling centers. It is then sorted to remove non-PET materials like caps, labels, and contaminants to ensure quality input material
The sorted PET flex undergoes thorough washing stages including pre-washing to remove loose dirt, chemical washing with detergents and caustic soda to dissolve adhesives and grease, followed by hot water washing at around 70–90°C. Multiple washings ensure removal of residual food, oils, and labels.
After cleaning, PET flex is shredded into small flakes or granules, typically sized between 10mm to 15mm, which are easier to process further into polyester fiber.
Advanced separation methods like float-sink tanks, air classification, and electrostatic separation are used to remove non-PET contaminants such as plastics, metals, and dust.
The cleaned PET flakes are dried using centrifugal or thermal drying techniques to reduce moisture content below 1-2%, preparing them for fiber processing.
Quality inspection includes visual checks, melt flow analysis, and spectroscopic tests to ensure purity, consistency, and compliance with industry standards.
The clean, dry PET flakes are then processed into polyester wadding through proprietary manufacturing lines that convert PET flex into soft, high-loft polyester fiber used in mattress filling, furniture cushioning, automotive insulation, and more.
