Flexitank Bulk Liquid: Cost-Effective Non-Hazardous Liquid Shipping
A Flexitank is a heavy-duty, multi-layered polymeric bladder that converts a standard 20-foot dry ISO ocean container into a bulk liquid transport unit holding 16,000 to 24,000 liters of non-hazardous liquid cargo, delivering 35% to 40% higher payload efficiency than traditional 200-liter drums.
Understanding Flexitank: Comprehensive Technical Analysis
Operational mechanism and commercial application in international freight
Flexitank technology revolutionizes the bulk liquid export sector by eliminating expensive ISO tank container repositioning fees and messy 200-liter metal drum handling. Installed inside a food-grade 20ft dry box container with protective corrugated cardboard lining and a reinforced steel bulkhead across the container door, a single-use flexitank bladder accommodates up to 24,000 liters (24 tonnes) of non-hazardous liquids. Extensively utilized in Turkish agricultural, food, and industrial chemical sectors, flexitanks transport olive oil, sunflower oil, fruit juice concentrates, liquid fertilizers, molasses, mineral lubricants, and water-based paints at a fraction of the cost of dedicated chemical tankers.

Aegean Olive Oil, Concentrates & Technical Oils from İzmir & Mersin
Authoritative operational insights under Turkish Customs Law No. 4458 & border regimes
Turkey is one of the world's leading exporters of olive oil, fruit juices, and industrial technical oils centered in the Aegean (İzmir Aliağa) and Mediterranean (Mersin) regions. Brosan Lojistik supplies certified multi-layer food-grade flexitanks equipped with bottom camlock filling valves, heat pads (for viscous liquids like palm oil or technical waxes that solidify in winter), and automatic pressure relief valves, certified to Container Owners Association (COA) standards.
Key Turkish Export Compliance Points
- •Capacity: 16,000 to 24,000 liters inside a standard 20ft container (payload ~21 to 24 metric tonnes).
- •Economic savings: Delivers 35% higher liquid volume per container compared to 200L drums and 15% higher than 1000L IBC totes.
- •Zero return freight: Single-use food-grade polyethylene bladders are 100% recyclable, eliminating ISO tank container cleaning and return fees.
Common Shipper Mistakes to Avoid
- ⚠️Attempting to transport hazardous chemicals (ADR classified goods) in a flexitank, which is strictly prohibited by maritime carrier regulations.
- ⚠️Under-filling or over-filling the bladder: filling below 90% creates violent liquid wave sloshing that damages container sidewalls during transit.
- ⚠️Failing to install heating pads for liquids that crystallize in cold climates, leaving the consignee unable to pump out the cargo.
Questions fréquemment posées for Flexitank
Direct answers to high-intent questions on responsibilities, costs, and risk
Q1:Can hazardous chemicals be transported in a flexitank?
No. Flexitanks are strictly certified for non-hazardous liquids only. Hazardous chemicals (ADR/IMDG classified goods) must be shipped in certified ISO tank containers or UN-approved intermediate bulk containers (IBCs).
Q2:How much more liquid fits in a flexitank compared to standard drums?
A 20ft container filled with 200L drums holds approximately 16,000 liters. A flexitank inside the same 20ft container holds up to 24,000 liters, an increase of roughly 40% in payload efficiency.
Q3:Are flexitanks reused or disposed of after delivery?
Flexitanks are single-use disposable bladders made of virgin polyethylene and polypropylene. Once drained at destination, the empty bladder is recycled, eliminating contamination risks and expensive return freight.
