Limitations and Defects of Flexitanks

Flexitank is a new packaging method invented and developed 25 years ago. It effectively transports and stores liquid cargo through ordinary containers. Thereby greatly reducing the logistics cost of liquid cargo. From the invention of the liquid bag to the current large-scale production and use, the material, design and use method of the liquid bag have undergone many reforms and updates. Even today, the technology and scope of use of the liquid bag can only be said to be relatively mature. In the process of continuous practice and exploration, the packaging method of flexitank will definitely be recognized and accepted by the market.

In logistics, no solution is perfect. Risk and cost are always in opposition, and enterprises are always constantly exploring the balance point as they grow. Here I only discuss some of the risks and disadvantages of flexitanks based on my personal understanding. The purpose is to let more people understand flexitanks objectively. Of course, the ability is limited, and more experts are expected to correct and supplement. thank you all!

Compared with iso tank, the main risks of liquid bag are:

Leakage: Speaking responsibly, leakage is inevitable. It is also the biggest obstacle to using liquid bag at present. There are many reasons for leakage, which are generally divided into: design defects of liquid bags; production quality defects of liquid bags; improper use (including scratches by foreign objects, violent collisions, etc.).

What can be done now is to improve the design, strictly control the quality, and strengthen customer guidance to reduce the risk of leakage. Through rapid network response, reasonable insurance claims further cover possible risks.

Drum box: Due to the improper arrangement of empty flexitanks, violent shaking of the container, or the use of non-standard containers, etc., the container box is bulged or even broken. -Strengthen customer guidance and rational use of flexitanks; at the same time, strengthen communication with transportation companies and rationally operate container flexitanks to reduce the risk.

Unloading residue: some goods cannot be unloaded because the inner layer material is adsorbed on the valve port and causes blockage. Or the inner layer material is broken, and the cargo penetrates between the inner layer material and the outer layer material, making it impossible to unload. This problem mainly occurs in multi-layer flexitanks, and single-layer flexitanks can be better solved.

Restrictions on the use of flexitanks

Scale requirements: storage tank equipment is required at the receiving and shipping places;

Liquid temperature requirements: Some liquids need to be heated, and the liquid bag is difficult to operate.

Ambient temperature requirements: Due to the characteristics of PE materials, it is difficult to operate at temperatures below minus 15 degrees.

Separate storage requirements: the flexitank after loading must be combined with the container operation.
