In the global industrial and commercial chain, glycerin is an indispensable raw material for the cosmetics, pharmaceutical, food, and even chemical industries. Its stable, economical, and safe transportation is crucial for ensuring the smooth operation of your supply chain. However, are you still plagued by the numerous shortcomings of traditional transport methods (such as steel drums, ISO tanks)?

Soaring costs? The procurement and cleaning recovery costs of the steel drums themselves, along with their significant dead weight and space wastage, continuously eat into your profits.

Cumbersome operations? Loading, unloading, stacking, and dismantling steel drums consume vast amounts of manpower and time, resulting in low efficiency that severely impacts port turnaround.

Quality risks? The risks of residue, contamination, and oxidation from multiple drum valves and welds constantly threaten the high-value quality of your glycerin.

Environmental pressures? The wastewater and waste residues generated from cleaning steel drums make it difficult to keep pace with increasingly stringent environmental regulations.

It's time for a change. A new solution has arrived: Flexitank transport.

Why are Flexitanks a Game-Changing Choice for Glycerin Transport?

Significantly Reduced Unit Costs: The transport volume per shipment is larger, leading to a significant reduction in unit cost.

Reduced Labor and Storage: Loading and unloading are convenient, requiring only simple pumping in and out, which drastically reduces labor and time costs.

Dedicated food-grade pipes and valves eliminate the risk of cross-contamination inherent in traditional methods due to repeated valve operations and container reuse, perfectly preserving the purity, color, and compositional stability of glycerin.

Rapid Turnaround: Filling and emptying speeds far exceed those of drum handling, potentially saving you up to 70% in port operation time, accelerating vessel and container turnaround, and making your supply chain more resilient.

Times are advancing, technology is innovating. Clinging to inefficient, high-cost traditional transport methods is akin to voluntarily surrendering profit and competitive advantage in an intense market.

Choosing professional flexitank transport is not merely selecting a type of packaging; it is choosing a smarter, more economical, and safer supply chain management model.

When chemicals, foodstuffs, fruit juices, oils, and other liquids safely cross mountains and seas, arriving at their destination intact, you might not realize that what guards this safety is far more than just a simple "plastic bag." It is an industrial-grade protection system—a flexitank—integrating materials science, precision engineering, and utmost responsibility.

At Uni Flexitank, we firmly believe that superior flexitank quality is "manufactured," not just "inspected." And the core of manufacturing lies with people.

The Heart of a Craftsman: Every Employee is the First Gatekeeper of Quality

In our view, every worker on the production line is not merely an operator but a "creator" and the "first quality inspector" of the flexitank.

We implement a strict "Pre-job Certification" system. Before any employee handles critical processes (such as high-frequency welding, valve installation, inner film sewing), they must pass dual assessments in theory and practical operation, deeply understanding both "why it's done this way" and "the consequences of not doing so." We certify individuals one by one, stationing them only upon qualification, eliminating human error at the source.

Self-inspection: Workers conduct 100% checks on their own completed work.

Mutual inspection: The next process step acts as the customer of the previous one. This creates a beneficial cycle where "defects don't leave the station, issues don't get passed on."

Specialized inspection: Dedicated quality inspectors perform sampling and full inspections at critical points.

By combining self-inspection, mutual inspection, and specialized inspection, we construct a seamless quality monitoring network.

The Purity of Environment: A Cleanroom as the Highest Tribute to Purity

Before entering, workers must pass through an air shower and wear specialized anti-static dust-proof suits, head covers, and gloves. We manage not just the product, but even the air and dust.

5S Site Management: Seiri (Sort), Seiton (Set in order), Seiso (Shine), Seiketsu (Standardize), and Shitsuke (Sustain). This is not just a slogan on the wall but a daily habit for every worker. An orderly, spotless workshop is the fundamental physical prerequisite for producing top-tier flexitanks.

Regular Training: Weekly quality analysis meetings and periodic industry knowledge updates keep our team technically advanced and highly vigilant.

Choosing us means choosing peace of mind. Because every consignment you entrust to us deserves our complete professionalism and dedication to safeguard.

Base oil—often called the lifeblood of industrial machinery—is the core component of lubricants and greases, typically making up 67–90% of the final product’s mass.

Chapter 1: Meticulous Planning – Safety Begins Before Loading

Safety is 90% dependent on preparation.

1.Accurate Compatibility Confirmation

2.Flexitank and Container: Inspect the container interior. Ensure the floor is even, free of any sharp protrusions, nails, or broken planks. The inner walls should also be smooth and without burrs.

3.Thorough Flexitank "Physical Examination": Before unfolding the flexitank, conduct a comprehensive visual inspection. Pay close attention to the valves and weld seams for any abnormalities. Although strict inspections are conducted before leaving the factory, potential risks from transportation and handling must be ruled out.

4.Essential Auxiliary Materials

Chapter 2: Precise Operation – Loading is the Critical Phase

1.Standardized Placement and Securing

2.Controlling the Loading Process: Adhere to the recommended filling flow rate and pressure. An excessively fast flow rate can generate significant hydraulic shock, creating instantaneous stress on the welds and the bag body.

3.Final Inspection After Loading: Once loading is complete, carefully check that all valves are tightly closed and look for any signs of leakage at the connection points.
