2.2 What is LDPE Pond Liner
LDPE pond liner is type of LDPE geomembrane liner specifically designed for lining ponds, water gardens, and other water containment applications. LDPE is a flexible plastic material with low density, which gives it certain characteristics suitable for pond liner applications.
LDPE Pond Liners are manufactured using a similar extrusion process as HDPE liners, but with a different type of polyethylene resin. They are available in various thicknesses, typically ranging from 0.3mm to 2mm or more, depending on the specific requirements of the project.

3 Why HDPE is Often Better Than LDPE for Large Pond Liners
Why HDPE is often better than LDPE for large pond liners? When comparing HDPE vs LDPE pond liners to explain why HDPE is often better than LDPE for r large pond liners, there are several key differences to consider. These differences relate to their material properties, performance, and suitability for different applications.
3.1 HDPE Features Superior Strength and Durability than LDPE
HDPE surpasses LDPE in molecular weight and density, resulting in superior strength and durability. These attributes make HDPE particularly advantageous for large pond liners, especially those covering expansive surface areas. The enhanced durability of HDPE significantly reduces the likelihood of punctures, tears, and other forms of damage, ensuring long-lasting and reliable water containment in large-scale pond applications.
BPM raw materials are all imported from Saudi Arabia and Qatar, using 100% virgin materials to ensure good quality and reliability from the production source.
3.2 HDPE Exhibits high Tensile Strength Than LDPE for Large Pond Liners
When selecting large pond liners, HDPE demonstrates notable tensile strength, which plays a critical role in withstanding the diverse stresses imposed on the liner. Factors such as water pressure and ground movement can exert considerable forces on the liner, making high tensile strength a crucial attribute. The ability of HDPE to endure tension is vital for preserving the structural integrity of the liner, ensuring its ability to withstand external pressures and maintain effective water containment in large pond applications.
During the production process, BPM strictly follows the ASTM GM13 standard, strictly controls the uniformity of thickness, and randomly selects samples for testing at regular intervals to ensure the tensile strength of the HDPE pond liner.
3.3 HDPE Features Better UV Resistance Than LDPE
Compared to LDPE, HDPE exhibits superior resistance to ultraviolet (UV) radiation. This attribute is particularly advantageous for large pond liners that are frequently exposed to sunlight for extended periods. HDPE’s enhanced UV resistance helps mitigate the effects of UV radiation, reducing the risk of degradation and prolonging the service life of the liner. By maintaining its integrity and performance over time, HDPE ensures reliable and durable water containment in large pond applications, even under prolonged exposure to sunlight.
