0.75mm LDPE Geomembrane Pond Liner
1.Precise and uniform thickness: 0.75mm standard thickness, with strict process control, the film material has a consistent thickness, ensuring stable and reliable anti-seepage performance.
2.Flexible and easy to bend: The LDPE material endows the film with high flexibility, allowing it to deform along with the uneven base surface without breaking, making it suitable for complex working conditions.
3.Strong welding seal: Good compatibility in hot melt welding, with seam strength reaching over 90% of the base material, forming a complete anti-seepage system and eliminating the risk of leakage.
4.Outstanding chemical resistance: Resistant to acid, alkali, and salt solution corrosion, suitable for highly corrosive environments.
5.Lightweight and easy to transport: Light in weight per unit area, facilitating handling and on-site laying, reducing transportation costs while enhancing construction convenience.
Product Introduction
The 0.75mm LDPE geomembrane is made from low-density polyethylene (LDPE) particles through the blown film process. The molecular chains are tightly wound to form a uniform film. The product thickness is 0.75mm. It has high flexibility (able to adapt to subsidence of the base surface), strong anti-seepage property (permeability coefficient ≤ 10⁻¹¹ cm/s), resistance to chemical corrosion (resistant to erosion by acid and alkali solutions), and weather resistance (-70℃ to 60℃ stable use). It is also easy to install and weld, and is widely used in water conservancy projects, environmental landfilling, agricultural anti-seepage, etc., providing long-term isolation protection.

Product Application
1. Leachate barrier for landfill: In landfill projects, 0.75mm LDPE Geomembrane serves as the core barrier layer, effectively preventing leachate from seeping out and protecting the soil and groundwater from contamination. It builds a long-term and secure barrier for the landfill.
2. Anti-leakage of sewage treatment tanks: Sewage treatment tanks are in constant contact with various types of sewage. 0.75mm LDPE Geomembrane, with its outstanding anti-leakage performance, prevents the sewage from leaking and polluting the surrounding environment. At the same time, its resistance to aging and UV radiation ensures the stable operation of the sewage treatment system.
3. Water conservancy project anti-permeation: In water conservancy projects such as reservoirs, canals, and artificial lakes, 0.75mm LDPE Geomembrane can effectively reduce water leakage losses and improve water resource utilization. Its good flexibility prevents soil and water erosion at the embankment and slope, enhancing the stability of the engineering structure and extending the service life of water conservancy facilities.
4. Agricultural anti-permeation and water retention: In agricultural irrigation systems, 0.75mm LDPE Geomembrane is used to reduce irrigation water leakage and improve water and fertilizer utilization. In the field of aquaculture, it is used for fish ponds and shrimp ponds to prevent leakage and maintain stable water levels and water quality, providing a favorable environment for aquatic products to grow and helping to increase production and income.
5. Treatment of mining tailings: Mining tailings ponds contain a large amount of heavy metals and chemical agents. 0.75mm LDPE Geomembrane is laid at the bottom and sides of the tailings pond to prevent tailings wastewater from leaking and polluting the surrounding ecology. Its high strength and anti-puncture performance can withstand the pressure of tailings accumulation and reduce environmental risks.
6. Anti-humidity and gas isolation in underground projects: In underground projects such as basements and underground warehouses, 0.75mm LDPE Geomembrane can effectively isolate underground humidity and harmful gases, preventing the building structure from getting damp and the items from moldy. Its excellent moisture-proof performance provides a dry and safe environment for underground spaces.
