HDPE 40 mil liner, also called 1.0 mm mil HDPE liner, is an effective waterproof geosynthetic material product. The HDPE Geomembrane pond liner can be divided into smooth geomembrane, Textured geomembrane and composite geomembrane according to the surface. BPM is the leading HDPE liner manufacturer and supplier in Pakistan. We wholesale geomembranr liner with complete size and specifications at great factory price. The HDPE 40 mil pond liner itself has the functions of anti-aging, acid and alkali resistance, and waterproofing, so it is widely used in seawater, freshwater fish and shrimp, mining engineering, wastewater treatment, landfills, and salt ponds.
1. What Is HDPE 40 Mil Liner?
HDPE 40 mil liner is an abbreviation for a high-density polyethylene (HDPE) liner with a thickness of 40 mils, which is equivalent to 1.0 millimeter. The term “mil” is a common unit of measurement used to express liner thickness, representing one thousandth of an inch or approximately 25.4 micrometers.
HDPE liners find extensive use in a wide range of applications that require effective containment and barrier properties. Common applications include landfills, ponds, reservoirs, and industrial storage facilities. The thickness of the liner is a critical factor that influences its durability, resistance to punctures or tears, and overall performance.

3. Why Chose HDPE 40 Mil Liner for Aquaculture Project in Sri Lanka
Choosing a 40 mil HDPE (High Density Polyethylene) liner for an aquaculture project in Sri Lanka can offer several advantages. Here’s why you might consider this option:
3.1 Durability
A 40 mil HDPE liner is relatively thick and provides excellent durability. It is resistant to punctures, tears, and abrasions, ensuring a long-lasting and robust solution for the aquaculture project. This durability is particularly important in aquaculture systems where the liner may come into contact with sharp objects or aggressive aquatic species.
3.2 Chemical Resistance
HDPE liners have good resistance to chemicals, including those commonly used in aquaculture systems such as disinfectants and fertilizers. This resistance ensures that the liner remains unaffected by the chemicals present in the water, preventing degradation and maintaining its integrity over time.
3.3 UV Resistance
Sri Lanka experiences high levels of sunlight throughout the year. Choosing a 40 mil HDPE liner ensures that it has enhanced UV resistance, allowing it to withstand prolonged exposure to sunlight without degradation. This UV resistance helps prolong the lifespan of the liner and maintains its structural integrity.
3.4 Flexibility
HDPE liners are known for their flexibility, allowing them to conform to the shape of the aquaculture pond or tank. This flexibility simplifies the installation process and ensures a secure fit, minimizing the risk of leaks or seepage.
3.5 Cost-Effectiveness
While the initial cost of a 40 mil HDPE liner may be higher compared to thinner liners, its durability and long lifespan make it a cost-effective choice in the long run. The reduced need for frequent replacements or repairs translates to lower maintenance expenses and overall project costs.
3.6 Local Availability
HDPE liners are commonly available in Sri Lanka, making them easily accessible for aquaculture projects in the country. Local suppliers and professionals are likely to have expertise and experience in working with HDPE liners, providing reliable support and guidance throughout the project.

5. What Are The Benefits of 40 Mil HDPE Liner Sri Lankafor Aquaculture Project?
The 40 Mil HDPE liner used in aquaculture projects in Sri Lanka offers several benefits that contribute to its effectiveness and suitability for such applications. Here are some key advantages:
5.1 High Strength of 40 Mil HDPE Liner
The HDPE liner exhibits high tensile strength, with a yield strength of up to 17kn/m and a breaking strength of up to 27kn/m. This strength ensures the liner can withstand the pressures and forces exerted on it within aquaculture environments, such as water pressure and the weight of fish and equipment. The liner’s good ductility and elongation at yield and break further enhance its ability to withstand stress and deformation.
5.2 Surface Compliance and Weather Resistance
The 40 Mil HDPE liner has good surface compliance, allowing it to conform well to the substrate and provide a seamless and effective barrier against water leakage. Additionally, the liner demonstrates excellent weather resistance, maintaining its performance and integrity even when exposed to harsh environmental conditions, including UV radiation, temperature fluctuations, and moisture.
5.3 Anti-Seepage Ability
The HDPE liner possesses a low anti-seepage coefficient, typically less than 1×10-13cm/s. This property ensures that the liner effectively prevents the seepage of liquids, such as leachate from aquaculture ponds or rainwater infiltrating into enclosed areas. By maintaining a reliable barrier, the liner helps to preserve water quality, prevent contamination, and maintain the integrity of the aquaculture system.
5.4 Chemical Stability
HDPE is known for its excellent chemical stability. The HDPE liner resists corrosion from various chemicals, including acids, alkalis, and other substances commonly found in aquaculture environments. This chemical resistance allows the liner to maintain its performance and integrity over a long period, even when exposed to potentially corrosive elements.
5.5 Aging Resistance
The 40 Mil HDPE liner exhibits strong aging resistance, meaning it can maintain its original performance and structural integrity over an extended period. Even with long-term exposure to sunlight, weathering, and other environmental factors, the liner retains its strength, flexibility, and resistance to degradation. This ensures its long-term effectiveness and durability in aquaculture projects.
The 40 Mil HDPE liner offers high strength, good anti-seepage ability, chemical stability, and aging resistance. These properties contribute to its ability to provide a reliable, long-lasting, and environmentally safe solution for aquaculture projects in Sri Lanka.
