Companies transporting juice must pay special attention to current safety regulations. All of our products are produced in clean room environment according to requirements laid out by FSSC 22000. Depending on the cargo, we can use oxygen barriers, air vents, or aseptic solutions.


Our flexitanks are applicable for reefer containers or trucks that require a temperature controlled journey. In sea freight we provide door to door specialized service with our exclusive global partners CMA CGM and Teconja.


We can help you ship all types of juice, including orange, apple, citrus, grape, aloe vera, berries, plum, coconut water and more. LiquA have developed the highest capacity reefer flexitank on the market. With R-Flex Juice you can ship 22,000 litres / 22 tons of juice in any 20’ reefer or 26,000 litres / 26 tons in any 40’ reefer.  This ability to carry a higher payload creates savings across your entire supply chain.

What is R-Flex Juice?

R-Flex Juice is LiquA’s innovative flexitank for juice shipments in 20’ or 40’reefer containers with unique designs and unmatched superior features that add value to the juice industry by delivering a higher quality juice product compared to any other bulk shipment alternative.

What are the main features and advantages of R-Flex Juice?

R-Flex Juice has some distinctive features that no other flexitank can offer.

Higher capacity: R-Flex Juice can load up to 22,000 litres in a 20’RF – offering a savings of 37.5% on overall freight cost compared to the other options on the market. R-Flex Juice can also load up to 26,000 litres in a 40’RF providing significant savings by higher payload.

Higher juice quality at destination: By design, R-Flex Juice has positive pressure which allows zero oxygen permeability. Also, the added protection of LiquA’s patented Nnautilius Technology in 20’RF and Ccaterpillar Technology in 40’RF means R-Flex Juice provides an extremely stable journey for your precious commodity. In combination, these technologies deliver your juice products to their destination in the best condition possible - better than any other flexitank product on the market.

Better Chilling: As per the optimum design of R-Flex Juice for the purpose, chilled air circulates through the entire surface of the flexitank, such as bottom, top and even through the space in the core of the flexitank for better circulation of cold air, supported by positive inner pressure. This results in better chilling of the juice allowing for longer transport times when needed.

Aseptic filling option: Our Aseptic Valves are specifically produced according to the needs of the food and beverage industry. The inclusion of a British Standard Juice valve with integrated steam jets and a stainless steel butterfly means you can now ship products like UHT in bulk to destinations all over the world.

Safety: Thanks to patented Nnautilius Technology used in 20’RF shipments and Ccaterpillar Technology used in 40’RF shipments, R-Flex Juice is a self-standing flexitank. It does not exert any pressure on the walls of the container, thus preventing any sidewall bulging or damage to container - even in an unlikely freefall event caused by mishandling during intermodal transitioning.

What is Nnautilius Technology?

While conventional flexitanks can hold liquid inside, they do nothing to stop its movement. When free to ‘slosh’ around during transit, the movement of liquid payloads generates high hydrodynamic forces, putting stress on the container side walls and doors. Nnautilus technology is an innovative approach specifically designed to minimize this movement, dramatically reducing the formation of hydrodynamic forces - keeping the cargo safe and stable during transportation. You can find further information about Nnautilius Technology here.

What is Ccaterpillar Technology?

Caterpillar technology uses a long mono block tube/bladder that has several “rings” to shrink down the total circumference at certain areas to compartmentalize the bladder—similar to a caterpillar. Should there be a force toward the back or front like a sudden vehicle break during transit, the design’s rings create bottlenecks that help dissipate any energy created by the liquid moving around. This helps avoid the formation of hydrodynamic forces and keeps your cargo safe. You can find further information about Ccaterpillar Technology here.

What is positive pressure?

Due to its unique patented design, the inner positive pressure of R-Flex Juice is always greater than the pressure on the surface. That ensures that no oxygen can get in.

Is there any scientific explanation regarding the positive pressure of R-Flex Juice?

Yes. It can be explained by Fick’s law of diffusion: “If the pressure of the liquid is greater on one side than the other side of a membrane, liquid will flow from the higher pressure side to the lower pressure side until the pressure of both sides are in equilibrium.” Based on the above principal, due to higher than exterior positive inner pressure from the juice throughout the surface, oxygen molecules on the air CANNOT penetrate through the liquid film and CANNOT cause any bacterial activity on the juice at any point. You can see that illustrated above. This is the case, even if there is no special oxygen barrier such as EVOH or Aluminum.

A simpler example to that would be a balloon filled with water. If a pin hole is opened on the surface of a balloon, water will flow out but air will not be able to get in due to the higher inner pressure.

How come that other flexitanks do not have the same positive pressure?

Conventional flexitanks get their strength from the container; the weight of the juice is mostly on the container. Such flexitanks exert pressure to the container sidewalls, which at times cause bulging. R-Flex Juice, is a self-standing flexitank by design. Its patented design ensures that the weight of the juice is on itself rather than the container. Therefore the inner pressure is much higher compared to any other flexitank.

What kind of service do you offer for sea freight?

Shipment of perishable food grade liquids requires a high level of specialization. Having years of experience in these segments, LiquA not only has developed the right flexitanks for shipping those products in 20ft and 40ft reefer containers but also has created the right global alliance by partnering with CMA CGM and Teconja to deliver the products safely door to door.

A specialized shipping line in that segment, CMA CGM has considerably increased its fleet of reefer containers to service this project. Another specialized company in the segment, Teconja has combined the container fleet and the flexitanks with their seamless freight services. The exclusive global alliance is the one and only proposal offering such product and service for the industry.
