The bulk containers comprise numerous polyethylene layers with an external covering of woven polypropylene with volume ranging from 12000 to 26000 liters for transporting non-hazardous liquids using the typical 20-ft railway or sea container. That is, it turns a 20 ft. container from dry goods to a liquid carrier.

They comprise custom formulated polyethylene where the ingredients undergo approval by the U.S. FDA for the transportation of a broad range of liquid foodstuffs. Furthermore, they undergo approval by strict international bodies for the transport of bulk liquid, making them safe and environmentally friendly.

Another element that ensures the safety of our flexibags for sale is the fact that they comprise quality materials that meet the prerequisites of the Code of Practice. These tanks comprise polyethylene because it’s impact-resistant, temperature-resistant, and UV resistant.

Uses of Flexibags

Since a flexibag offers high efficiency and remarkable contamination prevention, they function well for transporting non-hazardous chemicals as well as food-grade goods such as fruit concentrates and edible oil.

Fuel Storage

You can store and transport liquid fuels such as diesel in our reliable flexitanks for sale. They function primarily for storage and feature a berm and protective lining to offer additional containment safety to the neighboring environment.

Water Storage

Flexibags occupy minimal space and allow easy transportation. In case of emergencies or throughout disaster reliefs, they can work for storing and transporting portable water.

Storage of Food-Grade Liquids

Flexitanks for sale permit the safe storage of food-grade ingredients such as juices and milk.

Primary Storage and Single-use

Our flexibags for sale can reduce the overall storage expenses in instances where liquid storage isn’t for a long period.



Our flexitanks for sale are less costly than IBCs, drums, and ISO tanks. The cost of using a flexibag is 33% less than what’s required to spend during the transportation of bulk liquid in conventional bulk containers.

Faster Unloading & Loading

These storage containers don’t need a forklift to unload or load. This makes the unloading and loading process quicker by up to 90%.

Maintain Product Quality

Our flexibags for sale maintain liquid quality intact. They comprise polyethylene layers, each fitted with a valve and pump, making them waterproof, airproof, and weatherproof. Their design makes them ideal for single-use, which helps decrease the likelihood of contamination considerably. Also, it makes a flexibag a cheaper choice than using drums.

How it Functions

You should install a flexibag in a 20-ft container, which takes approximately 10-20 minutes. Upon installation, you’ll simply have to attach the connecting device to the flexitank. Using the pump you can begin loading, which will take 20-40 minutes based on the pump and cargo type. Once our staff finishes loading, the flexitank is ready for travel along with your cargo.

Flexibags Installation and Preparation

You should take the following precautions during the installation and preparation of a flexibag.

  • The container’s inner wall should be covered with layers that spread to the entire height of the filled flexitank. This protects our flexitank from rubbing against bare material.
  • Ensure the fitting and positioning of the flexibag inside containers occur by specially trained personnel who should position them per manufacturer instructions
  • You shouldn’t wear shoes in the container throughout flexibag installation and floor protection to prevent damage to the protection material while guaranteeing a clean surface. Throughout the entire transportation process, you shouldn’t step on the flexibag to avoid damaging the flexibag surface
  • The flexibag needs visual examination for apparent damage
  • Bulkhead installation should take place per the manufacturer’s instructions

Flexibags Labeling

The container should have a mark indicating that the container has a flexitank with liquid cargo. Furthermore, the gross weight of the collapsible tank should be mentioned on the marking. Bear in mind that markings should be evident on the flexitank such that they’re visible when opening the freight container.

A warning mark shouldn’t obscure other markings evident on the container. Moreover, marks should comprise a material meant to remain intact in difficult marine conditions for 90 days minimum. It’s worth noting that the warning mark should comprise a pictorial warning and text.

Cargo Heating

It might be necessary to adopt a heating system to smoothen the unloading process because of weather conditions throughout transport or because of the product’s physical properties. If heating systems are necessary, the devices and method used for warming up the product must be part of the risk evaluation. We recommend the following:

  • You should keep the desired temperature below the maximum temperature designated by the manufacturer
  • You should consider the influence of the tank’s design, for instance, multi-layer tanks versus a single-layer
  • You must consider the capacity of the heating system to increase the cargo temperature, considering environmental temperature and ambient cargo temperature
  • The cargo must remain static throughout the heating
  • Heating should take place next to the unloading point
  • The cargo must be appropriate for heating and the melting point shouldn’t surpass the flexitank’s maximum temperature
  • We recommend you choose an external layer that comprises a material, which offers extra mitigation benefits, for instance, resistance to sharp angles or welding burs that could rupture the bag

Flexitanks offer a safe and affordable means of storing and transporting bulk liquids. Nonetheless, appropriate equipment and operating procedures are essential.
