Food-Grade Safe HDPE Geomembrane Liner with UV Resistance 70% and Excellent Acid and Alkali Resistance for Aquaculture

Food-Grade Safe & Biological Friendly: Adopting pure HDPE raw materials with no harmful additives, the liner is non-toxic, tasteless and pollution-free. It does not cause water quality deterioration or biological damage, fully meeting aquaculture safety standards and ensuring healthy growth of fish, shrimp and other aquatic organisms.

Smooth Surface & Anti-Algae Easy Cleaning: The uniform smooth surface effectively reduces algae and dirt adhesion, avoiding bacterial breeding and water turbidity. It simplifies daily pond cleaning and maintenance work, greatly reducing later management costs and keeping the water body clean and transparent for a long time.

Excellent Anti-Seepage & Water Locking Performance: The dense molecular structure delivers ultra-low permeability, completely blocking water seepage and underground water backflow. It stably maintains pond water volume, effectively solving the water loss problem of traditional earthen ponds and saving water resources.

Superior Corrosion & Aging Resistance: HDPE material features strong resistance to acid, alkali, salt water and microbial corrosion. It also boasts excellent UV resistance and anti-aging performance, adapting to long-term outdoor exposure and water immersion without cracking, embrittlement or performance degradation.

High Toughness & Puncture Resistance: With good tensile strength and structural toughness, the liner resists friction, extrusion and slight puncture damage during use. It adapts to foundation slight deformation, ensuring long-term intact and stable anti-seepage structure.

Flexible Installation & High Cost Performance: Lightweight, soft and easy to cut, splice and lay. It fits various pond shapes and terrain structures perfectly with simple construction procedures. It shortens project construction cycles and delivers long-term service life, greatly reducing overall engineering and maintenance costs.
