PE liners, or polyethylene liners, are essential components in industrial settings, offering reliable containment solutions for a variety of applications. Made from high-density or low-density polyethylene, these liners provide robust barriers against water, chemicals, and contaminants. They are commonly used in pond construction to prevent seepage, in landfill systems to contain leachate, and in secondary containment structures to capture spills. Additionally, they line tanks, serve as geomembranes in civil engineering projects, and find applications in mining and agriculture. With their flexibility, durability, and excellent chemical resistance, PE liners play a vital role in safeguarding the environment, infrastructure, and human health in industrial environments.
