Advantags of PET strap making machine
1. Sustainable Material Processing – Uses 100% recycled PET (from post-consumer waste) for
eco-friendly, circular production.
2. Precision Extrusion Control – Fully automated PLC system ensures uniform plasticization and
stable extrusion, guaranteeing consistent strap quality.
3. Customizable Coatings – Optional surface treatments to enhance performance (e.g., higher
breaking strength, improved weld joint integrity for cotton bale
strapping).
4. Self-Cleaning Melt Filtration – Dual-piston filter with automatic venting and back-flushing
eliminates impurities, ensuring uninterrupted 24/7 operation.
5. Minimal Labor Requirements – Highly automated design enables continuous production with just
1–2 operators per shift.
Application of PET strapping
1. Heavy-Duty Industrial Packing
Steel & Metal Industry – Securing steel coils, pipes, and metal
profiles.
Building Materials – Bundling bricks, tiles, and construction rods.
Timber & Wood – Palletizing lumber and plywood.
2. Logistics & Warehousing
Pallet Stabilization – Reinforcing boxes and loads for transport.
Container Securing – Preventing cargo shifts during shipping.
3. Agricultural & Textile Packing
Cotton & Wool Bales – High joint strength for compression bundling.
Hay & Crop Bundles – UV-resistant for outdoor storage.
Why PET?
✔ Higher tensile strength than PP straps
✔ Resists moisture, chemicals, and extreme temperatures
✔ Maintains tension longer (low elongation)
✔ Recyclable & eco-friendly
