Our pillow-shaped flexible liquid storage tank, also named liquid storage bag, adopts high-frequency hot welding technology with thickened PVC or food-grade TPU coated fabric. Equipped with an exclusive detachable discharge pipe (retractable outlet tube), this collapsible bladder solves the cleaning, maintenance and replacement troubles of fixed pipe tanks. Unlike rigid metal plastic tanks, it can be fully folded flat when empty, cutting over 70% shipping and storage costs. It safely stores drinking water, irrigation water, fire fighting water, light fuel, neutral industrial chemicals and rainwater, widely used in agriculture, construction sites, disaster relief, mining and environmental water recycling projects.
