Side-by-side comparison

Flexitank vs. Rigid IBC

	FlexitankIncluded for comparison.	Rigid IBCIncluded for comparison.
What it is	A single-use bladder fitted inside a standard shipping container for non-hazardous bulk liquid.	A caged or moulded intermediate bulk container, usually around 275–330 gallons, on an integral pallet base.
Typical capacities	Commonly around 5,000–6,000 gallons.	Commonly 275–330 gallons.
Empty-container efficiency	—	Poor unless the format is collapsible or the empties never travel.
Reuse	Single-use.	High in closed loops, low when empties must cross long distances.
Sustainability	Very low packaging weight per litre, but the bladder is not recovered.	Long service life, but reverse logistics dominate the footprint.
Advantages	Highest liquid volume per container for suitable products. No empty packaging to bring back.	Fewer handling units per truckload of product. Valve discharge simplifies decanting. Robust protection for the filled leg.
Limitations	—Non-hazardous products only, with carrier approval. —Needs bulk pumping at both ends. —One product per container; no mixed loads.	—An empty rigid IBC ships almost entirely air. —Cleaning and reconditioning add cost and lead time. —Warehouse footprint for empties is substantial.
Questions to ask your supplier	—Is the product accepted for flexitank shipment? —Can both sites pump bulk liquid?	—Do empties come back, or is this one-way? —Who reconditions them, and how often?

Educational comparison, not an engineering conclusion. Suitability depends on your product, process and lane — confirm specifications with your supplier.
