Industrial Tank Liners

Fleximake Commercial, Industrial and Farm Tank Liners

Leak-Proof, Custom-Built Tank Liners for Harsh Environments — Proudly Australian Made

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.
