Flexitank 深度技术解析与实操指南
跨境多式联运中的运作机制与国际商业实务应用
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.

土耳其出口通关与法定合规核心要点
- •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.
托运人与外贸企业常见操作误区防范
- ⚠️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.

Flexitank 常见高频问题解答
关于责任划分、国际运费与风险承担的权威答复
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.
