Flexibags provide the most efficient means of transporting bulk liquids from one location to another, whether via water or land. Our flexitanks provide superior protection against oxidation and contamination, ensuring that the liquid arrives at the intended destination in a great state.

Nonetheless, you must be cautious during the loading and unloading process to maximize our flexitanks for sale. Beware that even the best flexitanks need meticulous handling to obtain superior results. Here’s a look at how to load and unload these transportation tanks.

Loading Flexitanks

Appropriate loading of our flexibags is the most vital step in transporting bulk liquids. The first few things to watch for include the use of tested and dedicated hoses that have been stored in pristine conditions before use.

It’s equally important to examine whether all valves are in the appropriate position before you start the filling and ensure the container’s left door is shut properly before filling starts. After conducting these checks, we ensure we set up the filling hose in a manner that there’s minimal valve stress.

Furthermore, hose support must be mounted at one level as the valve to prevent strain on the coupling and hose. It’s worth noting that gases might affect the quality of some liquids, so our fillers ensure that gases don’t penetrate our flexibags during, before, or after filling.

Typically, the filling procedure should begin with a comparatively lower rate. After filling the initial 2000 liters, you can increase the rate to approximately 500-700 liters per minute, never surpassing 1000 liters per minute.

Another point worth noting is that contact between the flexitank’s valve and bulkhead shouldn’t occur with the interior of the container’s door. Furthermore, we ensure our staff from the producer to prevent underfilling or overfilling a flexitank.

Tips for Loading Flexibags


Adopt Dedicated Hoses

Before loading bulk liquids in our flexibags, we ensure the hoses have undergone appropriate cleaning and are meant solely for loading what’s being transported.

Appropriate Set up of Filling Hose

During hose set up, we ensure correct fitting because it places less valve stress.


Spill prevention is a significant aspect throughout the final unloading stage. Consider using drip trays and other mechanisms to prevent considerable wastage. Generally, unloading should start by opening the container’s right-hand side while the left one remains closed virtually throughout the process until the flexibag is almost empty. Once we complete unloading, we remove markings from the container immediately, revealing that the container is safe and clean for subsequent use.

Prevention Mechanism for Flexibag Spill Prevention

When loading liquefied products, drip trays are necessary to prevent wastage. Remember to open the container’s right side. The spillage mechanism will allow you to inspect for leakages before securing the container.

Flexitank Transportation

We adopt best practices to ensure spillage doesn’t occur throughout the transportation. In this case, we ensure the filler installs spillage mechanisms before transportation takes place. It’s equally important to visually examine for leakages before we secure the containers and prepare the transport vehicle.

We recommend that the vehicle for transporting flexitanks for sale feature wheel chocks to decrease liquid movement. After all, less movement results in the arrival of the product in a better condition. 

How the Flexibags Work

Although an ISO tank container is the common means for bulk liquid transportation, our flexitanks for sale provide alternative solutions. The intermodal containers comprise a bladder for the storage and transport of non-regulated liquids. Once the bladder is in the 20ft. container, fluids obtain protection against punctures. Since the container’s open end needs a bulkhead fixture, the bladder receives support from external expansion.

Sizes range between 16,000 and 26,000 liters and loading can occur from beneath. The interior bladder is appropriate for non-hazardous and food-grade liquids, for instance, edible oils and fruit juices. The bladder works to protect liquids against ambient air, thus decreasing oxidation.

You’ll find containers commonly lined with protective membrane or corrugated cardboard to avoid bladder punctures. Also, containers can comprise elements for temperature control. In terms of the cost, a flexibag can cost 50-80% less than conventional liquid containers such as ISO tanks and drums.

Factors to Consider when loading the Bottom and Top Discharge Flexitank

Our personnel works to ensure we load bottom and top discharge flexibags systematically and safely for cost-efficiency. Here’s a list of considerations worth watching for:

  • During flexitank installation, ensure it’s fastened to the container’s corners
  • Examine the capacity of the flexibag and fill it per the recommended capacity. Keep in mind that the maximum you can over or underfill the tank is 2%
  • Once the flexibag is full, move the hose to prevent it from being trapped between the container’s sidewall and flexibag.
  • The tank’s valve should be opened by taking out the locking pin and safety cap before pulling the valve’s lever outwards. In the case of bottom discharge flexibags, the loading hose must have correct support to prevent the downward pulling on the flexibag.
  • Remember to clean and drain any outstanding products from the hose before cleaning the valve appropriately. Moreover, we recommend you place a warning label on the container’s left door.

Flexibags offer a convenient means of transporting bulk liquids. However, safety standards exist to ensure appropriate loading, transportation, and offloading of products. If you’re seeking a reliable means of bulk liquid transportation, you can count on us to provide efficient transport using our flexitanks.
