Fleximake designs and manufactures high-performance industrial tank liners using advanced high-frequency welding technology, engineered for leak-proof liquid storage, durability, and precision fit. Proudly Made in Australia in our manufacturing facility Victoria every liner is custom-built from reinforced industrial-grade fabric with a high-tensile woven core – resisting tears, punctures, and abrasion.
Our advanced welding methods fuse materials to create seams that are stronger than those of our competitors, delivering:
• Zero-leak guarantees – Even under high pressure or agitation
• Hygienic, gap-free seals – Critical for food-grade and potable water
• Unmatched durability – Resists extreme heat, cold, and wear
Ideal for fire water storage, agriculture, mining, municipal water storage, and food-grade applications, Fleximake offers tank liners that are certified for potable water and food contact.
Depending on your specific requirements, we can supply liner materials that meet the following certifications:
1. AS/NZS 4020 – Australian/New Zealand Standard for products used in contact with drinking water
2. NSF/ANSI 61 – American National Standard for drinking water system components
3. EU Directive – Compliance for materials intended for contact with food
Additionally, we can provide liners made from materials that comply with the FDA Code of Federal Regulations Title 21.
