Production line and factory setup overview
A small/medium line producing one PP raffia baler or crop-support twine family through resin blending, flat-film extrusion, quenching, slitting and fibrillation, hot drawing and annealing, yarn winding, controlled primary and secondary twisting, ball/spool winding, length/mass checking, tensile and knot-strength testing and protected packing.
Recommended lowest-entry line configuration Launch one UV-stabilized 2-3 ply crop-support or general agricultural twine from certified PP at 300-600 kg/day. Contract the complete route from raffia extruder through drawing/fibrillation, bobbins, twister and ball/spool winder. Recycled PP may be trialled only for non-safety general-purpose twine after contamination, strength, elongation and weathering validation.
Production process and implementation sequence
- Resin and additive release
- Raffia film extrusion and quench
- Slitting, fibrillation and hot drawing
- Annealing and yarn winding
- Primary/secondary twisting
- Ball or spool winding
- Length, mass and visual inspection
- Tensile, knot and UV release
Products, capacity and market fit
- Farm tying, baling and crop support create distributed repeat demand.
- A small complete line can serve local pack sizes.
- One twine construction controls twist and winding recipes.
- UV life, knot strength and length-per-package must be verified.
- PP crop-support twine - Linear density, ply, twist, breaking/knot strength, elongation, UV class, colour and package length - Orchards, vineyards and greenhouse growers
- General agricultural tying rope - Diameter, strand count, lay, breaking load and coil mass - Farms and merchants after separate tooling
