Linear Low-Density Polyethylene LLDPE Geomembrane

LLDPE geomembrane is a synthetic anti-seepage liner made from linear low-density polyethylene resin through extrusion or blow molding. Its molecular structure features short chain branches, giving the material increased flexibility and ductility, creating an optimized solution between HDPE (high rigidity) and LDPE (high ductility but low strength).

Looking for the best geomembrane LLDPE liner at the best factory price? NK Geosynthetics is a leading geomembrane and geotextile manufacturer and factory, providing optimal solutions to customers worldwide.

Manufacturing Process

Blow Molding (Three-Layer Co-extrusion Blown Film Method)

The blow molding process involves inflating HDPE polymer resin and other components into a cylindrical film bubble, which is then cooled and formed.

Width Advantage: Wider single-web products can be produced, reducing on-site splicing workload.

Uniform Mechanical Properties: Due to biaxial stretching, mechanical properties are uniform in both the longitudinal and transverse directions, with high tear strength.

Calendering: HDPE polymer resin and other components are rolled through high-temperature rollers to form a flat film.

Precise Thickness Control: The gap between the rollers allows precise control of product thickness, making it particularly suitable for producing thick geomembranes.

Standards: GRI GM17 (flexible membrane) or GB/T17643-2011.

The company has over 10 production lines and three quality inspection departments to ensure that the products delivered to you meet the required production specifications.

Advantages & Strengths

NuoKun's geomembranes undergo extensive research and testing, resulting in liners with numerous advantages that can be customized to your specifications.

1.Extreme Flexibility and Ductility:

Multi-directional elongation can exceed 400%, adapting to uneven settlement and foundation deformation, while offering excellent puncture resistance.

2.Chemically Inert:

Resistant to acids, alkalis, salts, organic solvents, and hydrocarbons, making it suitable for chemical and landfill leachate environments.

3.Excellent Low-Temperature Adaptability:

Remains flexible at -70°C, making it suitable for projects in cold and high-altitude areas.

4.Strong Environmental Compatibility:

No plasticizers added, meeting ISO9001 drinking water and aquaculture safety standards.

5.Long Lifespan:

Designed for 50 years in backfill conditions and approximately 7-10 years in exposed conditions.

Popular Applications

Deformation-Sensitive Projects:

Landfill closures, mine leaching ponds, and tailings ponds use Geomembrana 2mm or 60 mil HDPE liners (to mitigate settlement deformation).

Complex Structure Anti-Seepage:

Culverts, curved tunnel surfaces, and sewage pipe linings use 30 mil HDPE liners or Geomembrana 40 mil HDPE (due to its high conformability).

Ecologically Sensitive Projects:

Aquaculture ponds (fish/shrimp ponds) use 0.5mm anti-seepage liners or 40 mil HDPE geomembranes (to ensure non-toxicity) and drinking water reservoirs.

Small and Medium-Sized Water Conservancy Seepage Control:

Anti-seepage coatings on the bottom and slopes of small and medium-sized reservoirs, mountain ponds, and irrigation ditches.

Agricultural Facilities Seepage Control:

Moisture-proof layers on greenhouse foundations, integrated water and fertilizer storage tanks, and anti-seepage liners for artificial wetlands.

Municipal Small-Scale Liquid Storage Facilities:

Secondary anti-seepage coatings for rainwater collection tanks and regulating tanks at small sewage treatment plants.
