0.5mm Aquaculture Pond Liner
1. Superior Durability & Puncture Resistance
Crafted from 100% virgin high-density polyethylene (HDPE), the 0.5mm liner achieves a tensile strength of 27 MPa and 600% elongation at break, ensuring resilience against tears, roots, and sharp objects. Its three-layer co-extrusion technology enhances uniform thickness, reducing weak points compared to single-layer alternatives.
2. Cost-Effective Water Conservation & Operational Efficiency
The 0.5mm thickness optimizes the balance between affordability and performance, reducing seepage by up to 95% compared to traditional clay or concrete ponds. This minimizes water refill costs by 30-40% and stabilizes water quality, boosting fish/shrimp survival rates by 10-15%.
3. Eco-Friendly & Non-Toxic Solution
The liner is 100% recyclable and free from harmful plasticizers (e.g., phthalates) found in PVC alternatives. Its inert composition prevents soil/water contamination, ensuring safe habitats for aquatic life. Additionally, its lightweight design (0.45kg/m²) reduces transportation emissions and enables faster installation.
1. Introduction: The Need for Advanced Pond Liners in Modern Aquaculture
Aquaculture accounts for over 50% of global seafood production, but inefficient pond systems lead to 30-40% water loss annually due to seepage. Conventional materials like clay and concrete are prone to cracking, while PVC liners degrade under UV exposure. The 0.5mm HDPE Aquaculture Pond Liner emerges as a superior alternative, combining flexibility, strength, and longevity to optimize water use and reduce operational costs.
2. Technical Specifications & Performance Metrics
2.1 Material Composition & Manufacturing Process
The liner is crafted from 100% virgin HDPE resin with the following additives:
2.5% carbon black for UV resistance (ensuring 20+ years of outdoor life)
0.3% antioxidants & stabilizers to prevent thermal degradation
0.2% color pigments (optional for aesthetic or tracking purposes)
Produced via three-layer co-extrusion blow molding, this method ensures uniform thickness and enhances puncture resistance compared to single-layer alternatives.

The 0.5mm variant strikes an optimal balance between cost efficiency and durability, making it ideal for freshwater and brackish water ponds.
3. Product Advantages: Why Choose 0.5mm HDPE Liner?
The 0.5mm Aquaculture Pond Liner offers distinct benefits:
Superior Water Retention: Reduces seepage by 95%, cutting water refill costs by up to 40%.
Chemical & UV Resistance: Withstands aggressive disinfectants (e.g., chlorine) and prolonged sun exposure without degradation.
Easy Installation & Repair: Lightweight (≈0.45kg/m²) and flexible, enabling quick deployment even on irregular terrain. Minor damages can be patched with heat-welded HDPE patches.
Eco-Friendly: Non-toxic and recyclable, minimizing environmental impact compared to PVC alternatives.
4. Applications & Case Studies
4.1 Freshwater Fish Farming (Case Study: Vietnam)
A 10-hectare catfish farm in the Mekong Delta replaced its clay-lined ponds with 0.5mm HDPE liners, resulting in:
Water savings: 35% reduction in monthly refills
Increased yield: 15% higher survival rate due to stable water quality
Cost recovery: ROI achieved within 18 months via reduced water and maintenance expenses.
4.2 Shrimp Hatcheries (Case Study: Ecuador)
A shrimp hatchery using 0.5mm liners reported:
Zero seepage in high-salinity (35ppt) ponds
Extended liner lifespan: No degradation after 8 years of continuous use
Reduced chemical use: Liners prevented soil contamination, lowering disinfectant requirements by 25%.
