HDPE liner price per roll 2mm
Product Definition
HDPE liner price per roll 2mm refers to the total supply cost of a 2.0 mm thick high-density polyethylene geomembrane liner delivered in factory rolls, typically used for landfill, mining, reservoir, and industrial containment systems.
Technical Parameters and Specifications
Before evaluating HDPE liner price per roll 2mm, procurement teams must confirm compliance with recognized standards such as GRI-GM13 and relevant ASTM test methods.
| Parameter | Typical Value (2.0mm) | Test Standard |
|---|---|---|
| Nominal Thickness | 2.00 mm ±5% | ASTM D5199 |
| Density | ≥ 0.940 g/cm³ | ASTM D1505 |
| Tensile Strength at Yield | ≥ 29 kN/m | ASTM D6693 |
| Elongation at Break | ≥ 700% | ASTM D6693 |
| Puncture Resistance | ≥ 640 N | ASTM D4833 |
| Carbon Black Content | 2.0–3.0% | ASTM D4218 |
| Standard Roll Width | 5–8 m | Factory Specification |
| Typical Roll Length | 50–100 m | Project Dependent |
Roll weight typically ranges from 2,000 to 3,500 kg depending on width and length. These variables directly influence HDPE liner price per roll 2mm due to raw material consumption and freight considerations.
Structure and Material Composition
A 2mm HDPE liner is manufactured as a homogeneous sheet but contains engineered additives to ensure long-term containment performance:
Virgin High-Density Polyethylene Resin – PE100 or equivalent grade for high tensile strength.
Carbon Black (2–3%) – Provides UV resistance and long-term stability.
Antioxidant System – Enhances oxidative induction time (OIT).
Optional Textured Surface – Improves friction angle for slopes and landfill cells.
The resin grade and additive package significantly affect HDPE liner price per roll 2mm and expected service life (often 30–50 years when properly covered).
Manufacturing Process
1. Raw Material Feeding
Automated gravimetric blending ensures precise resin and carbon black ratios.
2. Extrusion
Flat-die or blown-film extrusion systems operate at 200–240°C. Continuous thickness monitoring maintains 2.0 mm tolerance.
3. Surface Treatment
For textured liners, embossing rollers create asperities to enhance slope stability.
4. Cooling and Calibration
Chill rolls stabilize sheet thickness and surface finish.
5. Quality Inspection
Online spark testing, tensile sampling, and carbon black dispersion testing are conducted before winding into rolls.
Automation level, production speed, and QC rigor all influence HDPE liner price per roll 2mm in competitive markets.
Industry Comparison
| Material | Thickness | Durability | Relative Cost | Typical Application |
|---|---|---|---|---|
| HDPE 2.0mm | 2.0 mm | Very High | Higher | Hazardous waste landfill |
| HDPE 1.5mm | 1.5 mm | High | Medium | Municipal landfill |
| LLDPE 2.0mm | 2.0 mm | Flexible | Similar | Irregular subgrades |
| PVC 2.0mm | 2.0 mm | Moderate | Lower | Temporary containment |
While the unit square meter cost is higher than thinner liners, HDPE liner price per roll 2mm provides improved puncture resistance and regulatory acceptance in critical containment projects.
Application Scenarios
EPC Contractors: Landfill base liners and leachate ponds.
Mining Companies: Heap leach pads and tailings storage facilities.
Industrial Operators: Chemical containment lagoons.
Water Infrastructure Developers: Large reservoirs and canal lining.
Distributors/Importers: Supplying regional infrastructure projects.
For projects exceeding 100,000 m², optimizing HDPE liner price per roll 2mm can significantly reduce total containment system cost.
Core Pain Points and Solutions
1. Fluctuating Raw Material Prices
Solution: Negotiate index-linked contracts tied to PE resin benchmarks.
2. Installation Damage Risk
Solution: Specify protective geotextile underlayment (300–800 g/m²).
3. Seam Integrity Concerns
Solution: Use double-track wedge welding and perform air pressure channel testing.
4. Freight and Handling Complexity
Solution: Optimize roll dimensions for container loading efficiency.
Risk Warnings and Avoidance
Avoid liners containing excessive recycled content for primary containment.
Verify OIT and stress crack resistance results.
Ensure subgrade compaction and removal of sharp stones.
Do not select supplier based solely on lowest HDPE liner price per roll 2mm.
Procurement and Selection Guide
Define containment classification (municipal, hazardous, mining).
Confirm regulatory thickness requirements.
Review full laboratory test reports (third-party preferred).
Calculate total installed cost, not only HDPE liner price per roll 2mm.
Assess supplier production capacity and lead time.
Request sample roll and conduct visual inspection.
Verify logistics plan and container loading layout.
Confirm on-site welding supervision availability.
