Flexitanks for Liquid Transportation

Flexitanks for Bulk Liquid Transport

A flexitank converts standard dry shipping containers into bulk liquid transport vessels. They offer a cost-effective solution to shipping liquids in bulk around the globe.


What are Flexitanks and how can they help with Bulk Liquid Transport?

Flexitanks are flexible bags designed to fit inside a 20-foot shipping container, converting them into bulk liquid transport units. They offer a superior alternative to ISO tank containers and drums for shipping liquids such as wines, juices, oils, other food-grade liquids and non-hazardous chemicals. Effectively, flexitanks convert standard dry cargo containers into a one-way bulk liquid transport system that make exporting and importing liquid freight easy and cost-effective.

Flexitanks Benefits for Bulk Liquid Transport

  1. Cost-Effective: Flexitanks are a much cheaper alternative compared to ISO-tank containers, IBC’s and Drums. For example, the cost of using a flexitank is one-third of the cost as compared to such traditional alternatives.
  2. Large Shipping Capacity: Offering a volume of up to 24,000 litres, flexitanks can ship up to 50% more cargo than those of bottled cargo consignments, 40% more than drums and 15% more than IBC’s.
  3. Faster Loading and Unloading Times: Using a flexitank does not require the use of a forklift to load and unload containers. Instead, a hose is fitted to the container to easily load and unload the container of its cargo.
  4. Sustainable Logistics: Flexitanks reduce the Carbon Footprint during the transportation process. For example, they can significantly reduce carbon emissions (for sea transport especially), they reduce waste as cargo can be shipped in one container rather than a multitude of barrels or IBC’s. And finally, Flexitanks are recyclable and some are even designed to be re-usable.
  5. No Storage Required: Unlike drums, ISO-tanks and IBC’s, flexitanks do not require additional storage when not in use. Additionally, a flexitank itself is a reliable storage container for bulk liquids.
  6. Less Labor is Required: Because flexitanks are easy to handle, load and unload,  they require much less labor and thus, less costs.
  7. No Cleaning Costs: As flexitanks are either disposable or recyclable, there are no cleaning costs involved as there would be with ISO-tanks and drums.
