In today's globalized trade, how to safely and cost-effectively transport edible oil from production regions to destinations worldwide is a key focus for the fats and oils industry. Traditional methods using steel drums or dedicated tank containers (ISO TANK) involve high costs and numerous limitations. In contrast, the flexitank—an innovative flexible liquid packaging solution—is becoming the preferred choice for shipping edible oil by sea due to its outstanding advantages.

I. What is a Flexitank? Why Choose It?

A flexitank is a large, sterile bag made from multi-layer, co-extruded polymer materials, with a capacity typically ranging from 16,000 to 24,000 liters. It is placed inside a standard 20-foot general-purpose container, forming a temporary "mobile storage tank."

The core advantages of using flexitanks for edible oil transportation include:

Significant Cost Reduction:

Packaging Costs: Flexitanks are single-use, eliminating the costs associated with recycling and cleaning steel drums, as well as the high rental and repositioning fees for ISO TANKs.

Transportation Costs: A single flexitank load in a container is equivalent to approximately 180 steel drums, significantly increasing the shipment volume per trip and reducing the unit shipping cost.

Maximized Loading Efficiency:

Flexitanks fully conform to the internal space of the container, enabling "full-container-load" transportation. The loading efficiency is about 30% higher compared to break-bulk or drum shipments.

Ensured Oil Quality:

High-quality flexitanks feature an inner layer made of food-grade polyethylene (PE), which is non-toxic, odorless, and oil-resistant. Their single-use nature completely eliminates the risk of cross-contamination between different batches of goods. The fully enclosed transportation process effectively isolates the oil from oxygen and moisture in the air, preventing oxidation and rancidity.

II. Key Practical Considerations for Flexitank Oil Transportation

To successfully use flexitanks, the following key aspects must be strictly controlled:

Flexitank Selection: Models specifically designed for edible oil must be selected to ensure material compatibility and safety, along with relevant food-grade certifications.

Professional Operation: Before loading, the container must be thoroughly inspected to ensure smooth inner walls free of sharp objects. The placement, filling, and emptying of the flexitank must be performed by trained professionals using specialized pump and pipeline systems.

Full Process Monitoring: Proper valve design and operation are essential to ensure smooth loading and unloading with minimal residue.

Conclusion

With its cost-effectiveness, efficiency, and exceptional quality preservation capabilities, flexitank technology has become a cornerstone logistics solution in the modern international trade of edible oil. It represents not only an optimization of costs but also a significant upgrade in supply chain efficiency and food safety assurance.

Base oil—often called the lifeblood of industrial machinery—is the core component of lubricants and greases, typically making up 67–90% of the final product’s mass. Whether refined from crude oil or produced synthetically, base oils act as the carrier for additives and directly impact the quality, performance, and longevity of lubricants.

From automotive engines and construction equipment to precision gearboxes, hydraulic systems, and wind turbines, base oil keeps industries running smoothly. Its chemical stability, viscosity consistency, and purity are crucial to protecting expensive machinery and extending service life.

Logistics Challenges: Purity and Cost Go Hand in Hand

Due to its high value and critical role, base oil must be shipped with care. Key challenges include:

● Preventing Contamination: Any foreign particles can degrade product quality and impact downstream applications.

● Maintaining Chemical Stability: Packaging must resist chemical reactions or swelling that could compromise the oil.

● Efficient Bulk Handling: Different viscosities require smooth loading and unloading without residue or product loss.

● Cost Control: With high volumes in global trade, choosing the right bulk transport method has a major impact on operational costs.

Why Flexitanks Are the Smart Choice for Base Oil

Flexitanks—food-grade, multi-layer liners fitted inside standard 20-foot containers—are revolutionizing how base oils move around the world. Here’s why:

● Higher Payload, Lower Costs

One flexitank can hold up to 24,000 liters, compared to around 16,000 liters with drums. More oil per container means fewer shipments, lower freight costs, and greater efficiency for high-volume routes.

● Maximum Product Protection

UNI flexitanks use advanced multi-layer barrier films and a durable woven outer layer to protect the oil from leaks, evaporation, or contamination. Unlike drums or tanks that require cleaning, single-use flexitanks ensure every batch stays pure.

● Seamless Loading & Discharge

Base oil’s viscosity demands smooth flow. Flexitanks are designed for easy pump connections, allowing clean, efficient loading and unloading with minimal residue—saving time and reducing operational hassle.

● No Return Logistics

With flexitanks, there’s no need to manage cleaning or return trips for empty containers, cutting waste and operational costs.

● Sustainable and Compliant

UNI flexitanks are made from recyclable materials, aligning with the industry’s push for greener supply chains and lower carbon footprints.

Against the backdrop of the continuous optimization of the global lubricant supply chain, flexible flexitank technology is gradually becoming an important innovative direction in the field of lubricant transportation. As a modern liquid packaging solution, Uni Flexitank, with its significant cost advantages and environmental benefits, is transforming the traditional modes of lubricant transportation.

Technical Advantages Stand Out, Uni Flexitank Achieves Multi-Dimensional Breakthroughs

Compared to traditional iron drums and IBC totes, the core advantages of using flexitanks for lubricant transportation are reflected in three aspects:

1. Significant Reduction in Packaging and Transportation Costs

A single flexitank can carry 16,000 to 24,000 liters of lubricant, making full use of container space and reducing packaging material costs. Statistical data show that flexitank transportation reduces comprehensive logistics costs by approximately 30% compared to traditional packaging methods.

2. Improved Operational Efficiency and Adaptability

Flexitanks are designed for single use, eliminating the need for recovery and cleaning, which significantly simplifies operational processes. Their compatibility with standard 20-foot containers allows lubricant manufacturers to more flexibly arrange small and medium-sized batch orders. This is particularly suited for quickly responding to demands in emerging markets such as Asia-Pacific, the Middle East, and Africa.

3. Dual Breakthroughs in Environmental Protection and Quality Assurance

Uni Flexitank adopts a multi-layer co-extruded polymer structure, offering excellent barrier properties and strength, effectively preventing contamination or leakage during transportation. At the same time, it reduces packaging waste and water usage for cleaning, aligning with the industry's sustainable development goals.

Accelerating Industry Adoption, Multiple International Lubricant Companies Have Launched Pilot Projects

Several international lubricant companies have already begun pilot projects for flexitank transportation.

"Flexitank technology is reshaping the logistics model of the lubricant industry. This is not just a packaging revolution but an optimization and upgrade of the entire supply chain, bringing unprecedented flexibility and economic efficiency to the lubricant industry."

Lubricant manufacturers are closely collaborating with flexitank suppliers to jointly promote technological innovation, ensuring product safety and transportation reliability, thereby creating greater value for global customers.

Are you still using traditional steel drum packaging, plagued by its excessive weight, high packaging costs, cumbersome loading and unloading processes, and massive waste of storage space?

Have you tried disposable ton bags, only to be frustrated by uncontrollable leaks and damages during transit, as well as high residual losses after unloading?
