Production line and factory setup overview
A medium precision extrusion line converting qualified clean recycled PET bottle flake into industrial packing strap through sorting and metal removal, crystallization and deep dehumidifying, metered feeding, vented extrusion with continuous melt filtration and melt pump, one- or two-strand die forming, water quench, staged infrared reheating and orientation drawing, embossing, heat setting, controlled cooling, accumulator winding and tensile, elongation, camber and weld-joint testing.
Recommended lowest-entry line configuration Launch one 12-16 mm machine-grade strap on a single-strand 50-80 kg/h line using washed hot-washed PET flake with controlled PVC, moisture and intrinsic-viscosity limits. Include crystallizer/dehumidifier, vented extruder, continuous filter, melt pump, staged drawing/heat setting, embossing, automatic winder and strap laboratory. A bottle-washing plant is separate unless the feed is already qualified.
Production process and implementation sequence
- Flake inspection and metal removal
- Crystallization and dehumidifying
- Vented extrusion and melt filtration
- Melt-pump die forming and quench
- Staged reheating and orientation drawing
- Embossing and heat setting
- Cooling, accumulation and winding
- Strap and weld-joint release
Products, capacity and market fit
- PET bottle flake can become higher-value industrial packaging.
- Local strap serves bricks, stone, cotton, timber and logistics users.
- A single strand controls drying and draw quality at entry scale.
- Breaking load, elongation, camber and weld efficiency determine machine performance.
- Machine-grade recycled PET strap - Width, thickness, mass/metre, breaking load, elongation, camber, surface, coil and weld efficiency - Brick, stone, cotton, timber and logistics packers
