As global decarbonization policies accelerate, the demand for biofuels and Sustainable Aviation Fuel (SAF) is rapidly increasing worldwide. Europe, the United States, and Southeast Asia are continuously raising biodiesel and SAF blending mandates, driving strong growth in the cross-border transportation of liquid biofuel feedstocks such as palm oil, Used Cooking Oil (UCO), animal fats, and vegetable oils.

This fast-growing market is creating new challenges for bulk liquid logistics. Traditional transportation methods, including drums and ISO tank containers, are often limited by high operating costs, complex cleaning procedures, and inefficient turnaround times. As a result, more producers, traders, and logistics providers are turning to flexitanks as a more efficient and economical transportation solution.

Designed for standard 20-ft containers, flexitanks can load up to 24,000 liters of non-hazardous liquid cargo, significantly increasing payload compared with drums or IBCs. This higher loading capacity helps reduce freight cost per liter and improves overall supply chain efficiency—especially for large-volume biofuel feedstock exports from Southeast Asia to Europe and North America.

Flexitanks also offer major operational advantages. As a single-use solution, they eliminate the need for tank cleaning, return logistics, and repositioning of empty containers. This not only reduces operational complexity and costs, but also minimizes the risk of cross-contamination—an increasingly important factor for feedstocks used in renewable fuel production.

Food-grade multi-layer PE/PP materials provide excellent sealing and contamination protection during long-distance transportation. Combined with fast loading and unloading operations, flexitanks enable smoother cargo handling and shorter turnaround times across ports, rail terminals, and inland distribution networks.

Sustainability is another key reason behind the growing adoption of flexitanks in biofuel logistics. Lightweight packaging helps reduce transportation-related carbon emissions, while recyclable materials support greener supply chain initiatives and ESG goals.

As global demand for biodiesel and SAF continues to rise, efficient bulk liquid transportation is becoming more critical than ever. With their advantages in cost efficiency, operational flexibility, cargo safety, and sustainability, flexitanks are increasingly becoming an essential logistics solution for the future of biofuel feedstock transportation.

Palm oil is the world’s most widely produced and actively traded vegetable oil, alongside soybean oil and rapeseed oil as the “top three global vegetable oils.” According to the latest data from the United States Department of Agriculture, global palm oil production is projected to reach a record 80.7 million tons in the 2025/26 season, representing a year-on-year increase of approximately 3%.

Data from the Indonesian Palm Oil Association indicates that Indonesia’s crude palm oil output is expected to grow by about 7.19% year-on-year to 56.55 million tons in 2025. Meanwhile, the Malaysian Palm Oil Board forecasts Malaysia’s production to reach approximately 20.2 million tons in 2025, up around 4.9% from 2024.

With production continuing to rise, global palm oil trade volumes are expanding rapidly, driving increasing demand for efficient and cost-effective bulk transportation solutions.

Palm Oil: A Versatile Oil from Table to Industry

Palm oil’s position as the world’s leading vegetable oil is closely tied to its wide range of applications.

In the food sector, its excellent stability, strong oxidative resistance, and high smoke point make it widely used in instant noodles, biscuits, chocolate, ice cream, margarine, and blended cooking oils.

In industrial applications, palm oil and its derivatives serve as key raw materials for soap production, biodiesel, lubricants, and paper additives. In recent years, policies such as Indonesia’s “B40” biodiesel blending mandate have further expanded industrial demand for palm oil.

Meeting Bulk Demand: Why Flexitanks Stand Out

Facing massive shipment volumes, traditional transport methods—such as drums and tank containers—are increasingly constrained. Drums offer limited capacity, require intensive labor, and generate significant packaging waste. Tank containers involve high leasing costs, require repositioning of empty units, and demand complex cleaning processes with potential cross-contamination risks.

Flexitanks, by contrast, are ideally suited to the transportation characteristics of palm oil, effectively addressing these challenges:

l  Cost Efficiency: Designed for standard 20-ft containers, flexitanks can load up to 24,000 liters per unit—approximately 35% more capacity than drum transport. As a single-use solution, they eliminate the need for return logistics and cleaning, significantly reducing tank container rental and maintenance costs. Overall logistics costs can be reduced by 30%–40%.

l  Safety and Purity: Manufactured with food-grade multi-layer PE/PP materials compliant with FDA and EU standards, flexitanks provide excellent oxygen and contamination barriers, preventing oxidation and spoilage. Fully sealed systems ensure zero leakage, while the “one container, one flexitank” model eliminates cross-contamination risks and safeguards product quality.

l  Operational Efficiency and Flexibility: Installation and loading can be completed by two operators in approximately 20 minutes, far exceeding the efficiency of traditional methods. Flexitanks are compatible with multimodal transport—including sea, rail, and road—enabling seamless integration into global logistics networks and supporting stable export flows from Indonesia and Malaysia to worldwide markets.

l  Sustainability: Lightweight design helps reduce carbon emissions during transportation. After use, materials can be recycled, minimizing waste compared to drums or rigid containers and aligning with global green logistics trends.

As global palm oil trade continues to expand, flexitanks—offering low cost, high safety, superior efficiency, and strong adaptability—have become the preferred solution for large-scale bulk transportation. They empower businesses to capitalize on rising production, optimize supply chain efficiency, and ensure reliable, cost-effective delivery across global markets.

As the core category of flexible storage and transportation containers, flexitanks, with their prominent advantages of high efficiency, economy and flexibility, have been widely used in many industries such as grain and oil, food, chemical industry and daily chemicals. They are specially adapted to 20-foot standard containers for long-distance transportation and bulk storage of liquid goods. Compared with traditional barrel-type storage and transportation, flexitanks can greatly improve loading efficiency, reduce packaging and return costs, and become the preferred solution for many enterprises to optimize their supply chains. However, the exertion of flexitank advantages is always inseparable from standardized installation operations.

I. Core Importance of Flexitank Installation

Installation is the first line of defense for flexitank storage and transportation, and also the basic link determining the success or failure of storage and transportation. Its standardization is directly related to three core aspects: first, flexitank service life. Standardized installation can avoid flexitank damage caused by uneven force and friction scratches, and improve the stability of its single use; second, cargo safety. It can effectively eliminate cargo loss caused by flexitank leakage and damage, especially suitable for categories with high purity requirements such as food and fine chemicals; third, operating costs. It reduces additional expenses such as replenishment, maintenance and claim settlement caused by improper installation, and truly exerts the core value of flexitank in cost reduction and efficiency improvement. On the contrary, irregular installation is likely to cause potential safety hazards, which is not worth the loss.

II. Specific Key Points for Flexitank Installation (Must-See)

The installation operation must follow the three core steps of "cleaning — installation — fixation", and each step has clear detailed requirements, which are specifically as follows:

1. Container Cleaning: Eliminate Scratch Hazards Before installation, the interior of the container must be thoroughly cleaned, and sharp debris (such as iron nails, gravel, plastic edges), residual stains and protrusions in the container must be removed one by one; for sharp parts such as welding joints and corners in the container, additional anti-collision strips or protective pads must be pasted to ensure that the inner wall of the container is smooth and free of foreign objects, and avoid flexitank scratches from the source.

2. Flexitank Installation: Accurate and Standard Placement Put the flexitank into the container smoothly, adjust the position of the flexitank to ensure that it is placed in the center without distortion or folding; the inlet and outlet valves of the flexitank must face the container door, which is convenient for subsequent filling and unloading operations, and avoids valve extrusion and collision.

3. Fixation and Protection: Prevent Displacement During Transportation After installation, fix the surrounding of the flexitank with special fixing belts, focusing on fixing the corners and valve parts of the flexitank; the fixing force should be moderate, which not only prevents flexitank displacement and friction during transportation, but also avoids flexitank damage caused by excessive extrusion, ensuring that the flexitank remains stable during transportation.

Standardized installation seems to be a basic detail, but it is the key to the safe storage and transportation of flexitanks and the effective exertion of their advantages. Only by strictly following the above key points and keeping the bottom line of installation can flexitanks truly save worry, reduce costs and improve efficiency for enterprises, and build a solid safety barrier for the storage and transportation of liquid goods.
