Aqualiner Fresh Water Tank Liner

Home \ Aqualiner Fresh Water Tank Liner



Pioneer Water Tanks, AQUALINER Fresh® antimicrobial tank liner is a world’s first to keep your water fresher, for longer.

For families across the world relying on the quality of tank water for their daily use and consumption, this means for the first time, being able to enjoy the additional peace of mind that comes with fresher, purer and cleaner water, thanks to the use of antimicrobial technology on the inside lining of Pioneer water tanks.

The AQUALINER Fresh® is manufactured utilizing a patented three-layer process that adheres 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 Technology is inherent in the Black Polyethylene Film that touches the water.



The Aqualiner Fresh® features excellent flexibility, high tensile strength, waterproof, and good abrasion resistance. The reliable liner Black PE film has Sanitized® treatment embedded into the top layer that touches the water, which prevents bacterial/microbial growth.

The ideal liner fabric used in water tanks is a balance and compromise of all the solutions that address the key criteria.

In designing a suitable liner fabric, some of the key criteria that need to be considered are:

• Flexibility
• Abrasion-resistant
• Tear and tensile strength
• Chemical resistance
• Fabric Weight
• Shrink resistance/ stability
• Waterproofness

The above graph demonstrates the estimated value against each of the key criteria considered during design and evaluation of AQUALINER Fresh®

AQUALINER Fresh® is the first water tank liner to be embedded with Sanitized® antimicrobial technology. The black PE film layer of the AQUALINER Fresh® that touches the water is embedded with antimicrobial protection by Sanitized®.

This treatment has the following features.

• Keeps your water fresher for longer
• Prevents bacterial and microbial growth
• NSF-61 Certified for drinking water storage
• Developed with Collaboration with Gale Pacific; CE Bartlett Pty Ltd and Pioneer Water Tanks
• World Class Protection Additive
• Patented Technology

The Aqualiner Fresh® tank liner is constructed from a weave is the most practical method to achieve the desired tear and tensile strength. A fabric without a weave will continue to stretch when the tank is filled (particularly if the tank wall is corrugated) and then relax when the water level drops. The water level in a tank will rise and drop several times throughout the lifetime of the liner, thus resulting in a thinner and less secure liner over time. This is why the Aqualiner Fresh features the proprietary weave made of high tenacity multifilament Polypropylene.

The AQUALINER Fresh® is pressure-tested and it retains its shape due to the weave structure.

Other tank liners that don’t utilize a weave, stretches at any weak point. Once the stretching starts, it continues in this area thus making the fabric thinner and thinner and weaker and weaker. Until it finally bursts.

The Aqualiner Fresh® tank liner used in Pioneer Water Tanks is third-party NSF 61 certified for drinking water storage. The National Safety Foundation standards for drinking water are developed by a team of scientists and industry experts to guarantee products worldwide.

The NSF/ANSI 61 Drinking Water System certification is accepted worldwide and is applicable for drinking water across North America.
