    AQUALINER® Fresh Tank Liner Layers

    The AQUALINER® Fresh is manufactured utilizing a patented three-layer process that adheres to a PP Multifilament Base with a Polyethylene Film on the surface.

    • The PP base, PP/PE Coating, and PE Film are all bound together through a process called Extrusion Coating.

    • The PP Multifilament Base provides strength, flexibility, and dimensional stability.

    • The PE Film provides toughness, water-resistance, and heat seal characteristics.

    • Sanitized® antimicrobial Technology is inherent in the Black Polyethylene Film that touches the water.

    SANITIZED® Antimicrobial Technology

    Pioneer Water Tanks partnered with SANITIZED – the world’s leading company in antimicrobial hygiene function and material function – to create a new cutting-edge tank liner that works to protect against the build-up of mold, algae, mildew, and biofilm.

    The advantage of harnessing world-class technology from the Swiss-based company SANITIZED in a water tank application is that the interior surfaces of your tank are actively working against bacterial growth.

    Sanitized® technology complies with the strictest international health guidelines. The AQUALINER® Fresh tank liner has been rigorously tested for its functionality and safety for potable, drinking water storage applications. Safely store water long-term with Pioneer Water Tanks for fresh and clean water supply.
