Flexitanks and ISO tanks are both used to transport bulk liquids. They are both designed to hold the same amount of liquid, but there are some key differences between them that you should consider before making your decision.
Flexitanks: Flexitanks are made from flexible materials such as rubber or plastic, which allows them to expand or contract depending on how much liquid is inside them. Because they’re made of flexible material instead of metal like an ISO tank would be, they’re more lightweight and easier to handle during shipping than their rigid counterparts–but this also means that they can’t withstand as much pressure without bursting open (which could cause damage). Also unlike an ISO tank, there aren’t any rules regarding how long it takes for a flexitanker company’s employees who handle these vessels during loading/unloading operations; this means that there may be fewer regulations regarding health & safety protocols while working around these containers (since they’re not considered hazardous materials).
Capacity
The capacity of a flexitank is usually measured in cubic meters, while an ISO tank is measured in cubic feet. A standard 20′ ISO tank can hold up to 8,000 gallons (30 m3) of liquid, while a 40′ ISO tank holds 16,000 gallons (60 m3). A standard 40′ flexitank holds up to 30,000 gallons (113 m3).
While both types of tanks take up roughly the same amount of space when empty and full respectively–about 4 feet by 8 feet–the difference between them becomes apparent when they’re being used as part of your shipping process: The larger the volume capacity you need for your shipment, the more likely it will be that using an ISO container would be more cost effective than renting multiple smaller units.
Hazardous Materials
In the case of hazardous materials, both Flexitanks and ISO tanks can be used. However, there are some differences in what you can transport in each type of container.
Flexitank: The Flexitank is designed to be used as a bulk liquid shipping container for non-hazardous products only (i.e., those that do not pose any danger to human health or the environment). It’s not designed for transporting hazardous materials like acids or flammable liquids, so if you need one of these types of products shipped anywhere, you’ll need another type of tank instead (like an ISO Tank).
ISO Tank: In contrast with the Flexitank’s limited capabilities when it comes to transporting dangerous substances like acids or flammable liquids–and despite being more expensive–the ISO Tank has been specifically designed for this purpose; therefore making it ideal if your business needs something sturdy enough to handle these types of materials safely but also affordable enough so that everyone can afford them!
Packaging Requirements
Flexitanks are a little more flexible in terms of packaging requirements. They can be shipped in a variety of containers, including:
- ISO tanks
- Drums and IBCs (intermediate bulk containers)
- Bulk liquid tankers (BLTs)
There are some differences in packaging requirements for each type of container. For example, if you’re using an ISO tank or drum/IBC to ship your product, you’ll need to purchase additional dunnage around the product to ensure that it doesn’t shift during transit. The amount of dunnage needed will depend on how much space there is between the liquid level inside your Flexitank and its base–this distance varies depending on what kind of product is being shipped and how much weight it has.
Costs
The cost of a Flexitank is lower than that of an ISO tank. The reason for this is because the flexible container can be used to ship bulk liquids, while the rigid one cannot. There are many factors that determine how much you will pay for each type of bulk liquid shipping container.
One example would be if you need to purchase a new container because your current one has been damaged or lost during transit, then this will be more expensive than purchasing a new Flexitank since it’s not designed specifically for shipping purposes. In addition, if there’s damage done to your shipment during transport then it may require extra repairs before being able to be reused again which could increase costs further down the line depending on how serious those repairs were needed too fix up properly again (this could include things like replacing broken glass panels).
Environmental Impact
The environmental impact of shipping liquids in flexitanks and ISO tanks is a critical consideration. Both options have their pros and cons, but in general, flexitanks are much more sustainable than ISO tanks.
Flexitank shipping containers are made from recycled plastic, which means they don’t require new raw materials to be produced. They also require less energy to manufacture than an ISO tank does because they’re lighter weight and require fewer parts to assemble together into their final shape (they’re made up of just three pieces). This makes them easier on the environment overall–there’s less pollution created during production and transportation of these units than there would be if they were made out of heavier materials like steel or aluminum.
ISO Tanks: The Cons
In addition to being heavier than flexitanks (which means more fuel will be used), ISO tanks also require more labor-intensive assembly processes that involve welding together many different parts into one unit before it can be used as part of your shipment process; this increases both costs for you as well as CO2 emissions from manufacturing processes themselves!
Flexibility
Flexitank and ISO Tank are both flexible containers, meaning they can be used in a variety of different ways. The main difference between the two is that flexitanks are designed for short-term use, while ISO tanks are meant to be used for bulk liquid shipping over long periods of time.
One thing that makes flexitanks more flexible than other types of shipping containers is their size and shape: they can hold up to 3,000 gallons (11,356 liters) at once–a much larger capacity than most other kinds of tanks! This means you can transport more products at once with this type of container without having to worry about running out of space or having too much weight on one side of your vehicle due to uneven distribution throughout your shipment.
However, if you’re looking for something with even greater flexibility than what’s offered by a standard-sized tank (like those listed above), then consider using our special “Flexi” option instead–this allows customers who need extra room inside their shipment compartment(s) access those spaces without having them filled completely full with product(s).

Durability
Durability is one of the most important factors to consider when choosing a tank. A durable container will last longer, require less maintenance and be more cost-effective in the long run.
It’s important to note that there are two types of containers: flexitanks and ISO tanks. The main difference between these two options lies in their construction materials; flexitanks use high-quality plastics while ISO tanks are made from steel or aluminum alloy.
If you’re looking for an affordable option that won’t break down on you after just a few uses, then you might want to go with a flexitank (or “flexible bulk container”). These containers can hold up against harsh weather conditions like extreme heat or cold temperatures without cracking under pressure–which makes them great for shipping liquids like chemicals or oils across long distances!
Conclusion
You now have a better understanding of the key advantages and disadvantages of each container. The ISO tank is more expensive than the flexitank, but it has many benefits that make it worth the extra cost. If you’re shipping liquids in bulk, then this is your best option.
If you’re shipping smaller quantities or using less specialized equipment, then flexitanks may be a better choice for you because they are cheaper and easier to use.
