Strategic project overview
A large strategic wide-sheet extrusion plant producing certified smooth or textured HDPE pond-liner geomembrane through gravimetric virgin-resin and carbon-black masterbatch dosing, high-capacity extrusion with fine melt filtration, flat-die distribution, three-roll calendering, online thickness scanning, edge trimming, controlled cooling and haul-off, wide-roll winding, laboratory conditioning and density, carbon-black, tensile, tear, puncture, stress-crack and oxidative-induction testing.
Recommended feasibility and development stage Treat this as a large project. Launch one smooth 1.0 or 1.5 mm, 5-7 m wide HDPE geomembrane at 400-600 kg/h using certified virgin geomembrane resin and qualified carbon-black masterbatch. Include gravimetric dosing, wide flat die, calender, online gauge, roll handling and a GRI-GM13-capable laboratory. Installation welding equipment and certified field seams are a separate but essential service scope.
Project development and implementation stages
- Certified resin/masterbatch release
- Gravimetric dosing and extrusion
- Fine melt filtration and flat-die distribution
- Three-roll calendering
- Online thickness scanning
- Cooling, trimming and haul-off
- Wide-roll winding and conditioning
- Full geomembrane laboratory release
Project rationale and industrial impact
- Irrigation ponds, canals and water-storage projects need durable seepage control.
- Wide rolls reduce field seams and installation risk.
- Afghan solar exposure and rocky subgrade demand verified puncture and UV durability.
- Manufacturing quality alone does not replace professional liner design and field welding QA.
- Smooth HDPE pond-liner geomembrane - Thickness, width, density, carbon black content/dispersion, tensile, tear, puncture, stress crack, OIT, roll length and traceability - Irrigation ponds, reservoirs, canals and water projects

Indicative project investment and implementation basis
These figures are early planning references, not a supplier quotation. A bankable feasibility study must confirm feedstock, market, process route, utilities, environmental controls, infrastructure, financing, contingency and implementation risk.
| Project scope | Indicative range | Planning basis |
|---|---|---|
| Dosing, extrusion, filter and wide die | US$280k-620k | 400-600 kg/h certified route |
| Calender, gauge, cooling and winding | US$220k-520k | 5-7 m wide handling |
| Laboratory, crane and utilities | US$120k-310k | GM13-type release capability |
| Freight, civil works, erection and spares | US$180k-450k | Large-project installation |
| Indicative installed project total | US$800k-1.90m | Land, building shell, resin and field installation excluded |
