The global food and beverage industry continually seeks to improve efficiency without compromising safety or quality. For shippers handling high-volume sweeteners such as fructose, sorbitol, and corn syrup, traditional packaging—drums, barrels, or IBCs—is often inefficient, costly, and environmentally burdensome. The solution? Flexi tanks containers. These innovative bulk liquid transport systems have revolutionised the way these viscous, sensitive liquids are moved across oceans and continents, offering a compelling blend of cost savings, hygiene, and operational ease.

A flexitank is a high-capacity, flexible, single-use polymer bladder designed to be installed inside a standard 20-foot dry-box shipping container. This simple integration transforms a standard container into a safe, sterile, and highly efficient vessel for transporting liquid cargo. While the process is highly effective, the high viscosity and temperature sensitivity of syrups require specialised handling to ensure a smooth journey from origin to destination.

Understanding the Nature of Fructose, Sorbitol, and Corn Syrup

Fructose, sorbitol, and corn syrup are highly viscous liquids, meaning they flow slowly and can thicken in cold conditions. Their high sugar content and temperature sensitivity require specialised logistics handling.

Any lapse in transportation conditions can affect texture, colour, and even sweetness, impacting end-product quality. Flexitanks provide a sealed, temperature-controlled, and contamination-free environment that protects these delicate products during long-distance shipments.

Why Flexi Tanks Containers Are the Ideal Choice

1. Maximise Capacity, Minimise Cost
   A single flexitank can safely carry up to 24,000 litres. This is a significantly higher volume than can be shipped using multiple drums or intermediate bulk containers (IBCs) within the same 20-foot container space. This volume maximisation directly reduces overall freight costs per unit and minimises the labour and equipment required for handling individual packages.
   
   
2. Guaranteed Hygiene and Purity
   Flexitanks are single-use and constructed from food-grade, sterile materials. This ensures that the product is transported in a completely clean environment, eliminating the significant risk of cross-contamination inherent with reusable containers. High standards of hygiene are non-negotiable for transporting food-grade liquid cargo.
   
   
3. Boost Operational Efficiency
   Manually loading and unloading hundreds of drums is slow and labour-intensive. Flexitanks, conversely, are loaded and discharged using streamlined pumping systems. This automation significantly reduces turnaround times, enabling quicker port cycles and a more efficient supply chain.
   
   

Eco-Friendly Bulk Liquid Transport

Flexi tanks containers eliminate the need for heavy, often non-recyclable packaging. The materials used in modern flexitanks are 100% recyclable, making the bulk liquid transport process a more sustainable and environmentally conscious choice.

Navigating the Challenges: Key Considerations for Syrup Transport

Fructose, sorbitol, and corn syrup are highly viscous liquids. Successful bulk liquid transport requires careful pre-planning, primarily focused on managing temperature to ensure smooth discharge.

Temperature Control is Crucial 

• Primary Challenge: Viscosity increases sharply as syrup cools, making discharge slow, difficult, and potentially wasteful.
• Heating Solutions: Specialised flexitank systems use integrated heating elements or pads (hot water/steam) to raise product temperature just before discharge, restoring pumpable viscosity.
• Insulation: Sensitive syrups may require thermal insulation within the flexitank or transport in refrigerated containers (reefers) to maintain a stable temperature.

Pre-Loading Inspection and Preparation 

• Container Selection: Use only robust 20-foot dry-box containers with a minimum 30-tonne weight rating and sound corrugated sidewalls.
• Container Preparation: Meticulously inspect the interior of the container for rust, sharp edges, or debris. Install a protective corrugated lining and a reinforced bulkhead to brace the flexitank during transit.

Safe Loading and Final Discharge

• Controlled Rate: Fill and empty the flexitank at a steady, controlled rate to prevent over-pressurisation and potential damage to the tank or container structure.
• Valve Security: Sterilise and securely fasten all inlet and outlet valves before and after use to prevent contamination and leaks.
• Maximising Recovery: Use an efficient pump for rapid unloading. For maximum product recovery, the flexitank can be strategically rolled towards the valve to push out remaining syrup.

Fluid Flexitank – The Smart Choice for Syrups
