Brown (Amber) Recycled PET Flakes
Hot-washed flakes from post-consumer brown/amber PET bottles: graded, tested and documented for every shipment.
Clean, Uniform Brown PET Flakes for Industrial Use
General Eco Tech produces hot-washed Brown PET flakes from post-consumer PET bottles. Raw bottles are sorted by colour and run through a multi-stage washing line that removes labels, adhesives, caps, moisture, PVC and other contaminants. Every batch is graded and tested before dispatch.
The flakes have an intrinsic viscosity of 0.70 ± 0.02 dl/g, a flake size of 2–12 mm and moisture of ≤ 1.0%, with ferrous and non-ferrous metal at 0.0 ppm. Available in sheet-grade and fiber-grade, hot-washed as standard with cold-wash on request, in volumes up to 2,000 tonnes per month.

Grades
Sheet-Grade
Ultra-clean hot-washed flakes with very low PVC content, processed to stringent contamination thresholds. Suitable for rPET resin production and sheet applications.
Fiber-Grade
High-purity flakes for polyester fiber, industrial textiles, non-woven materials and non-food packaging, with consistent IV and low contamination.
Applications
- rPET resin manufacturing (bottles, containers, injection-moulded products)
- Textile & fiber: polyester staple fibre, non-woven fabrics, industrial textiles
- Industrial packaging: PET strapping bands and rigid packaging components
- Films & sheets
- Dark masterbatch
- Automotive underbody parts and fibre filling
- Specialty products: geotextiles, insulation materials, engineered composites
Parameters Tested Per Batch
- IV value (intrinsic viscosity)
- Colour coordinates (L, B)
- Moisture content
- Bulk density
- PVC contamination
- Adhesive residue (glue content)
- Polymer contamination
- Metal content
- Flake size distribution
- Post-bake colour stability
Packaging
- 1,000 kg woven jumbo bags with liner
Flakes are packed in woven polypropylene jumbo bags with internal polyethylene moisture-barrier liners and container desiccant packs for ocean transit.
Documentation
Every batch is tested and the results are issued as a formal Technical Data Sheet that accompanies each shipment. Export documentation, LC-based and FOB arrangements are supported.
