l Our 40ft solutions are designed for ocean, rail, road, and multimodal transportation, supporting trade corridors where 20ft availability may be limited.
l When evaluating flexitank manufacturers, consider manufacturing capability, cargo compatibility, material technology, container support, customization, and technical service — not simply unit price.
l LAF Technology’s 40ft solutions are backed by 10 years of proven experience and railway-related certifications including CRCC, AAR, and Ukrainian Railway requirements.
Global bulk liquid logistics is becoming increasingly dependent on flexible equipment strategies. For shippers moving food, industrial oils, chemicals, and other compatible non-hazardous liquids, the question is no longer only which flexitank to use — it is also which container format best fits the cargo, route, and available equipment.
This is creating new interest in the 40ft flexitank.
A 40ft solution does not replace the established 20ft flexitank model. Instead, it gives shippers another option when 40ft containers are more readily available on a particular trade lane, at a specific port, or during periods of equipment imbalance.
For companies evaluating 40ft flexitank manufacturers, the key considerations are capacity, cargo compatibility, material technology, container suitability, installation, unloading, and technical support — not simply the advertised volume.
Container availability varies between ports, trade lanes, and operating periods. In some logistics scenarios, 20ft equipment may be difficult to secure while suitable 40ft equipment is more readily available.
LAF’s 40ft flexitank is designed to help companies make productive use of available 40ft container resources. The solution helps alleviate transportation pressure caused by limited 20ft container availability and provides a more flexible equipment strategy for bulk liquid transportation.
A 40ft flexitank can also create opportunities to use empty containers on return routes more productively, potentially improving equipment utilization for container owners, shipping lines, and logistics providers.
The practical question is not whether 40ft is universally better than 20ft. It is whether a 40ft container provides a suitable combination of availability, payload, cargo compatibility, and transport economics for a particular shipment.
A 40ft flexitank is a flexible bulk liquid transportation system designed for installation inside compatible standard 40ft containers, including 40GP and 40HC units.
LAF’s 40ft flexitank can carry up to 28,000 liters, depending on cargo density, container specifications, loading conditions, and applicable transportation regulations. The solution is designed for ocean, rail, road, and multimodal transportation of compatible non-hazardous liquids.

A 40ft flexitank may be worth considering when:
l Suitable 20ft containers are difficult to secure
l 40ft equipment is more readily available on the required route
l The shipment volume can make practical use of the additional container capacity
l The cargo is compatible with flexitank transportation
l The shipper wants more flexibility in container sourcing
l Multimodal transportation is required
A 40ft flexitank may be less suitable when shipment volume does not justify the container size, when specialized temperature-controlled equipment is required, or when the cargo is classified as dangerous goods.
The decision should therefore be based on the complete logistics system rather than container size alone.
We provide solutions for a wide range of applications across the food, industrial, and non-hazardous chemical sectors:
Food applications include edible oils, sunflower oil, rapeseed oil, soybean oil, corn oil, wine, fruit juice, milk, animal fats, coconut oil, olive oil, palm oil, peanut oil, rice bran oil, syrups, and sweeteners.
Industrial applications include bitumen, base oils, lubricating oils, mineral oils, biodiesel, glycerin, transformer oil, used cooking oil, white oil, and other compatible industrial oils and fats.
Non-hazardous chemical applications include ethylene glycol, plasticizers, fatty acids, latex, fertilizers, polyols, emulsions, surfactants, paraffin, and hydraulic fluids, subject to compatibility assessment.
For this reason, a professional flexitank manufacturer for liquid transportation should evaluate the cargo before confirming the product configuration.
For food applications, buyers evaluating food grade flexitank manufacturers should consider food-contact materials, hygiene controls, traceability, and applicable certifications.
For industrial oils, viscosity, density, chemical compatibility, loading temperature, and discharge requirements become increasingly important.
LAF’s 40ft solutions use high-performance PE films tailored to cargo properties, including food-grade, barrier, high-temperature, and low-temperature configurations. We also offer customized capacities, valve configurations, bag structures, heating systems, barrier films, and low-residue designs.
For food-grade options, see Food-Grade Flexitank.
Bitumen is one of the more demanding bulk liquid applications because of its temperature and viscosity requirements.
For bitumen flexitank applications, LAF provides specialized high-temperature solutions. Our 40ft Bitumen Flexitank is designed for compatible bitumen transportation and supports filling temperatures of up to 120°C.
LAF’s commercialized 40ft Bitumen Flexitank can achieve more than 20% higher loading efficiency compared with traditional 20ft tank solutions, with a maximum loading weight of up to 25 tons per container under applicable conditions. The solution supports multiple bitumen grades, including 60/70, 85/100, and 200/300, with each filling cycle taking approximately 30 minutes. Between May and July 2025, full-scale field trials were conducted from loading sites in the Middle East to unloading sites in China.
These figures apply specifically to LAF’s bitumen solution and should not be interpreted as general specifications for all 40ft flexitanks.

A useful flexitank manufacturers comparison should go beyond unit price.
Manufacturing capability — Does the supplier control film production, heat sealing, assembly, and quality testing? Manufacturing integration can improve material traceability and production consistency.
Cargo compatibility — Can the manufacturer evaluate density, viscosity, temperature, chemical compatibility, and discharge requirements before shipment?
Material technology — Does the supplier offer appropriate film structures for food-grade, barrier, high-temperature, or low-temperature applications?
Container and installation support — Can the supplier provide container suitability guidance, standardized installation procedures, and loading supervision?
Customization — Can the manufacturer adjust capacity, valve configuration, heating, film structure, or other components according to the cargo?
Technical service — Can the supplier support customers during installation, loading, transportation, and unloading?
These criteria are particularly useful when comparing China flexitank manufacturers, 40ft flexitank manufacturers, or other international suppliers.

Safety depends on the complete transport system rather than the flexitank alone.
Cargo compatibility, container condition, correct installation, loading conditions, transport requirements, and unloading procedures should all be evaluated before shipment.
LAF provides standardized installation procedures, SOPs, on-site installation and loading supervision, and pre-shipment inspection support for our 40ft Flexitank solutions.
A LAF 40ft Flexitank can carry up to 28,000 liters, subject to cargo density, container specifications, loading conditions, and applicable transportation regulations.
The maximum advertised volume should therefore not be treated as the guaranteed loading volume for every liquid.
No.
The two formats serve different logistics requirements. A 20ft flexitank remains appropriate for many established bulk liquid routes, while a 40ft flexitank provides an additional option when container availability, shipment volume, or route conditions make 40ft equipment practical.
The value of the 40ft format lies in greater equipment flexibility and higher potential payload per container, rather than replacing the 20ft model altogether.
