A flexitank container is a flexible bladder system designed for transporting bulk liquids within standard shipping containers. These innovative flexitank logistics solutions can hold up to 27,000 litres of non-hazardous liquids, making them a cost-effective alternative to traditional tank containers. Flexitank shipping services have revolutionised how companies transport everything from food-grade oils to industrial chemicals across global supply chains.
What exactly is a flexitank container?
A flexitank container is a flexible bladder made from food-grade polyethylene that fits inside a standard 20-foot shipping container. This system transforms an ordinary container into a liquid transport vessel capable of carrying bulk liquids safely and efficiently.
The flexitank itself consists of multiple layers of polyethylene film with a protective outer layer that prevents punctures during loading and transport. When empty, these flexible containers can be folded and stored compactly. Once filled, they expand to utilise the full interior space of the shipping container, maximising cargo capacity while maintaining structural integrity.
Flexitank providers typically supply complete systems including the bladder, valve assemblies, and bulkheads that secure the flexitank within the container. This design allows standard shipping containers to be converted temporarily for liquid transport without permanent modifications, making flexitank freight forwarding highly versatile for companies with varying cargo needs.
How much liquid can a flexitank actually hold?
A flexitank can hold up to 27,000 litres of liquid cargo, significantly more than drums or intermediate bulk containers. This capacity makes flexitanks particularly attractive for companies shipping large volumes of non-hazardous liquids.
The actual capacity depends on the liquid’s density and viscosity. Lighter liquids like wines or fruit juices can reach the full 27,000-litre capacity, while denser products may be limited by weight restrictions rather than volume. Most flexitank transport services help you calculate optimal loading based on your specific liquid characteristics and shipping requirements.
This substantial capacity translates into significant cost savings compared to traditional packaging methods. Instead of handling hundreds of drums or multiple smaller containers, you can ship the equivalent volume in a single flexitank container, reducing handling costs, packaging materials, and labour requirements throughout your supply chain.
What types of liquids can you transport in flexitanks?
Flexitanks are designed specifically for non-hazardous liquids, including food-grade products, industrial oils, chemicals, and agricultural liquids. Common cargoes include edible oils, wine, fruit juices, liquid fertilisers, and various industrial fluids.
Food-grade flexitank transport requires containers that meet strict hygiene standards and regulatory compliance. These flexitanks use food-safe materials and undergo rigorous quality testing to ensure they don’t contaminate the cargo. Many flexitank suppliers provide certificates confirming compliance with international food safety standards.
Industrial liquids suitable for flexitank shipping include lubricants, glycols, surfactants, and various chemical solutions. However, hazardous materials, corrosive substances, and products requiring temperature control above 60°C typically require specialised ISO tank containers instead. Flexitank logistics providers can advise whether your specific liquid is suitable for this transport method.
What’s the difference between flexitanks and ISO tank containers?
Flexitanks are single-use flexible systems for non-hazardous liquids, while ISO tank containers are reusable steel tanks designed for hazardous materials, gases, and temperature-controlled cargo. Each serves different cargo requirements and operational needs.
ISO tank containers offer greater versatility for challenging cargo types. They can handle hazardous chemicals, maintain precise temperature control, and withstand higher pressures. These permanent steel structures provide multiple uses over many years, making them cost-effective for regular shipments of specialised cargo.
Flexitank container services excel in cost efficiency for large-volume, non-hazardous liquids. They eliminate the need to return empty containers, reduce cleaning requirements between shipments, and offer lower per-litre transport costs for suitable cargo types. The choice between flexitanks and ISO tanks depends on your cargo characteristics, shipping frequency, and operational preferences.
Having access to both flexitank and ISO tank solutions provides flexibility to choose the most appropriate transport method for each shipment, optimising costs while maintaining cargo safety and quality standards.
How does flexitank transport actually work in practice?
Flexitank transport involves installing the flexible bladder system at origin, loading the liquid cargo, and shipping via standard container routes to the destination where the flexitank is discharged and disposed of responsibly.
The process begins with flexitank rental services delivering the system to your loading facility. Trained technicians install the flexitank inside a standard container, ensuring proper positioning and securing all valve connections. Your liquid cargo is then pumped directly into the flexitank through specialised loading equipment.
During transport, the flexitank moves through the global shipping network like any standard container. This flexibility means you don’t need to worry about scheduled tank container routes or managing specialised equipment fleets. The container can be transported by sea, rail, and road using standard logistics infrastructure.
At destination, flexitank logistics services coordinate the discharge process. The liquid is pumped out through the same valve system, and the empty flexitank is removed and sent for recycling. This end-to-end handling approach ensures smooth operations while maintaining cargo quality and safety standards throughout the journey.
Many flexitank shipping companies operate global networks that provide consistent service quality and technical support across different markets, making international liquid transport more predictable and reliable.
Understanding flexitank capabilities helps you make informed decisions about bulk liquid transport. These systems offer practical advantages for non-hazardous liquids, providing cost-effective shipping solutions that integrate seamlessly with global container logistics networks.
