For years, moving bitumen in a 40ft flexitank was considered impractical. High filling temperatures, internal pressure, and the need for consistent heat resistance made it one of the toughest challenges in bulk liquid logistics.
LAF has now changed that. After nearly two decades of R&D in liquid packaging, LAF has commercialized the industry's first 40ft Bitumen Flexitank — a solution that opens a new equipment option for high-temperature bitumen transport and helps shippers navigate fluctuating 20ft container availability.
Container availability is rarely consistent. It changes by market, trade lane, season, and equipment type. In some logistics environments, 20ft containers are hard to secure, while suitable 40ft equipment is more readily available.
A 40ft flexitank does not replace the established 20ft model. Instead, it gives cargo owners, logistics providers, and container operators another configuration to consider when planning large-volume liquid shipments.
LAF's 40ft Flexitank solutions are designed for standard 40ft dry containers, including 40GP and 40HC units. They can accommodate up to 28,000 liters, depending on cargo density, container specifications, configuration, and applicable transportation requirements. The solutions support ocean, rail, road, and multimodal transportation.
Market context: According to Fortune Business Insights, the global flexitank market was valued at USD 951.31 million in 2025 and is projected to reach USD 3.2036 billion by 2034, at a CAGR of 14.62%. Asia-Pacific holds a dominant 39.25% market share, with China serving as a core growth engine supported by dense food and chemical manufacturing clusters and export activity.
Bitumen is one of the most demanding bulk liquids. It requires high filling temperatures, reliable heat resistance, and stable performance under pressure. LAF's 40ft Bitumen Flexitank is engineered to withstand filling temperatures up to 120°C and supports multiple bitumen grades, including 60/70, 85/100, and 200/300.
Each filling cycle takes approximately 30 minutes under applicable conditions. The solution enables a maximum loading weight of up to 25 tons per container, achieving more than 20% higher loading efficiency compared with traditional 20ft tank configurations.
This is not just a product improvement. It is a redefinition of what's possible in bitumen logistics.
“For years, the 40ft bitumen flexitank remained an industry challenge due to high internal pressure and heat resistance requirements. With nearly two decades of R&D expertise in liquid packaging, we have successfully brought this product from concept to mass production. This is not just a product breakthrough — it is a redefinition of bitumen logistics efficiency.”

Between May and July 2025, LAF's technical team completed full-scale field trials from loading sites in the Middle East to unloading sites in China. The trials validated stable operation, consistent temperature control, and safe product delivery across multiple bitumen grades.
Following successful validation, LAF has established long-term partnerships with key clients, confirming the commercial viability of the 40ft Bitumen Flexitank in real-world operations.
LAF's 40ft flexitank solutions are intended for compatible non-hazardous liquids across several industries.
Food-grade applications include edible oils, wine, juice concentrates, and other compatible food ingredients. LAF offers food-contact certified flexitanks for relevant products and markets, including certifications such as FDA, EU 10/2011, FSSC 22000, KOSHER, and HALAL. For details, see Food-Grade Flexitank.
Industrial applications include compatible industrial oils, base oils, lubricants, latex, and non-hazardous chemical liquids. Cargo compatibility should be assessed before shipment to determine the appropriate material structure, capacity, valve configuration, and operating conditions.
High-temperature applications include liquid bitumen and other compatible products requiring specialized heat-resistant materials. LAF's high-temperature flexitank technology is designed for filling temperatures up to 120°C for applicable cargoes.
A key feature of the 40ft flexitank format is its compatibility with multiple transportation modes.
LAF's 40ft Flexitank is suitable for ocean, rail, road, and multimodal transportation. This allows the same general equipment concept to be considered for international shipping, cross-border rail transportation, and combined logistics routes.
For railway applications, LAF offers flexitank solutions designed to meet applicable CRCC and AAR requirements, along with other railway-related certifications or approvals for specific markets. Certification requirements remain dependent on the specific route, railway operator, cargo, and transportation regulations.
As a professional flexitank manufacturer, LAF controls key stages of flexitank production, including material formulation, film production, valve integration, assembly, heat sealing, and quality testing.
LAF manages the process from resin and film through valves and finished flexitanks, with laboratory research, development, and testing supporting product formulation and application requirements.
For 40ft applications, technical considerations extend beyond the flexitank itself. Cargo characteristics, container condition, loading volume, temperature, transportation mode, and unloading requirements all need to be considered before shipment.
LAF provides technical guidance covering cargo compatibility and container suitability, helping customers determine the appropriate flexitank configuration for specific applications.
The maximum capacity of LAF's 40ft Flexitank is 28,000 liters.
Actual loading volume should not be determined by nominal capacity alone. Cargo density, container specifications, applicable transport regulations, loading conditions, and the characteristics of the liquid must be considered before confirming the loading plan.
For comparison, LAF's standard 20ft flexitanks offer a loading range of 14,000–26,000 liters, with capacity adjusted according to the liquid density.
For companies evaluating flexitank manufacturers or China flexitank manufacturers, LAF recommends assessing the complete transportation system rather than focusing only on the flexitank price or nominal capacity.
Key considerations include:
l Cargo compatibility: Is the liquid compatible with the selected film and valve system?
l Container suitability: Is the 40ft container structurally sound, clean, dry, and free of conditions that could damage the flexitank?
l Loading requirements: Are cargo density, loading volume, temperature, and loading procedures clearly defined?
l Transportation mode: Is the solution appropriate for ocean, rail, road, or multimodal transportation?
l Unloading: Does the cargo require specific pumping, heating, valve, or discharge arrangements?
l Certification: Are the required food-contact, quality, railway, or transportation approvals available for the intended market?
l Technical support: Can the manufacturer provide application guidance before shipment?
This application-based approach helps buyers distinguish between a general-purpose flexitank supplier and a professional flexitank manufacturer capable of supporting more specialized transportation requirements.
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 its 40ft Flexitank solutions. For safety guidance, see How Are Flexitanks Loaded and Unloaded Safely?
