Flexitanks and ISO tanks are solutions used for shipping liquids in bulk. Depending on the destination, the point of origin, the type of product to be shipped, and many other factors, one of the two solutions may be preferable over the other.
Although both are designed for liquid transport, Flexitanks and ISO tanks are distinctly different. In this article, we will examine the characteristics and benefits of these two different transportation methods to understand which one is the right choice for your business.
What are flexitanks and ISO tanks?
Before examining the advantages of these two solutions, let’s look at the construction and cargo of Flexitanks and ISO tanks.
Features of the flexitank
Flexitanks are flexible bags that can collapse and fit into an ISO container. These bags are used to transport non-regulated liquids (all liquids that are not subject to specific regulations or restrictions for their transport or storage, such as wines, beverages, oils, etc.). Flexitank walls have multiple layers of polyethylene with the inner layers made of flexible polyethylene, and the other layers made of polypropylene. The Flexitank needs an external structure to support itself when filled with liquid cargo. It is available in various sizes, typically ranging from 16,000 to 24,000 liters, and has the flexibility to accommodate different shipping container sizes. Flexitanks are generally designed for single-use, providing a hygienic and cost-effective solution for one-way shipments.
When to use Flexitanks
Flexitanks are suitable for transporting various types of non-hazardous liquids: from food products and pharmaceuticals, all the way to feed, chemical products, and industrial products. Some of the most commonly shipped liquids by Flexitanks are oil, wine, water, beer, detergents, emulsions, and additives.
Characteristics of the ISO tank
The ISO tank gets its name from the ISO standard. It involves tanks used for transporting both hazardous and non-hazardous liquids. The main characteristic that distinguishes an ISO tank from a flexibag is that the former is made of stainless steel. The inner walls of this tank are coated with protective layers, which serve to prevent steel corrosion and liquid contamination. ISO tanks are easily distinguishable by their cylindrical shape and the presence of a manway at the top.
When to use ISO tanks
ISO tanks are a safe and flexible solution for transporting any type of liquid cargo, as well as pressurized and refrigerated liquid gases. They are used for transporting both edible fluids and hazardous materials, like toxins, and flammable substances.
Differences between Flexitank and ISO Tank
We've seen what flexitanks and ISO tanks are, but let’s take a closer look at the differences between these two solutions, and how they are utilized for shipping services in various vertical markets:
Size: flexibags of various sizes exist, generally ranging from 16,000 to 24,000 liters. ISO containers, on the other hand, can transport from 5,500 to 11,600 gallons;
Duration: with regular maintenance and the required cleaning to meet hygiene and safety standards, ISO tanks can be used for up to three decades, unlike flexitanks which can be disposed of after one delivery;
Load capacity: in bulk liquid shipments, a single ISO tanker allows the delivery of large quantities of goods, which would otherwise require several flexitanks.
Conclusions
In recent years, the demand for flexitanks and ISO tanks has become increasingly significant, especially for wine shipping and oil and beverage shipping services. The choice between Flexitanks and ISO tanks ultimately depends on the specific requirements of the cargo, the frequency of shipments, handling capabilities, and environmental considerations.
