For optimal water quality
Water quality starts with the right tank liner. Black tank liners are widely used on the market, but our white liners offer certain other advantages.
Why choose a white liner?
- Temperature control: white liners reflect sunlight, helping to limit heat absorption in outdoor tanks. They keep the water cooler.
- Better visibility: white liners make dirt, sediment and algae easier to detect. This enables faster inspection and maintenance.
- Esthetics and hygiene perception: white surfaces create a clean and professional appearance, especially in certain sectors

Applications
White liners are ideal for warm climates especially for outdoor tanks without a cover. They are also widely used in temperate climates in applications where water quality, hygiene and control are critical.
In short, white liners reflect heat and make contamination easier to detect, helping growers maintain better control over water quality.
More chlorine resistant
Our white liners combine mechanical strength and UV resistance with a maximum Cl absorption of 5 ppm. This is more than the current usual liners used for storing clean water. Therefore they are more safe to be installed in operations where chlorine is used.
Thickness
NPI supplies the ENPEX MAX white liner as a standard in 0,75 mm. This film is doublesided white / black.
