What Are Chemical Flexitanks?

Principles of Chemical Flexitanks


Chemical flexitank transportation is an innovative method for storing and transporting liquids. Its core principle lies in using high-strength, corrosion-resistant, and excellently sealed flexible containers to safely load and transport various chemicals. These liquid bags are usually made from composite materials in multiple layers that effectively resist the risks of corrosion, penetration, and leakage that chemicals might pose.


Composition of Chemical Flexitanks


The materials used in chemical flexitanks are meticulously selected and designed to meet the specific needs of different chemicals. Generally, chemical flexitanks consist of the following components:


Inner Layer Materials


This is the part that directly contacts the chemicals, usually made from high polymer materials like polyethylene (PE). These materials have excellent corrosion resistance, effectively preventing the inner layer from being eroded by chemicals.


Outer Layer Materials


The outer layer is typically made from wear-resistant and tear-resistant reinforced materials, such as polypropylene (PP), to protect the liquid bag from mechanical damage and external environmental impacts.


Connection and Sealing Systems


The valve, vent valve, and other connection parts of the chemical flexitanks use high-quality sealing technology to ensure that chemicals do not leak during storage and transportation.


Applications of Chemical Flexitanks


Chemical Industry


Chemical flexitanks are widely used for packaging and transporting chemical raw materials, plasticizers, latex, detergents, disinfectants, and other non-hazardous liquid chemicals. Using chemical flexitanks for transportation can effectively reduce transportation costs and help minimize environmental pollution.


Oil and Fat Industry


In the vast field of the oil and fat industry, chemical flexitanks are extensively utilized for the packaging and transportation of key oil products such as vegetable oil, glycerin, and high-fatty acids. These products have very high requirements for the sealing and corrosion resistance of packaging materials, and chemical flexitanks, with their excellent sealing performance and corrosion-resistant materials, can precisely meet these stringent demands.


Additionally, in specific application scenarios, food-grade liquid bags within the liquid bags can also be used for transporting beverages like wine and various concentrated fruit juices. This application requires the materials of the liquid bags to strictly adhere to food safety standards to ensure that the transported food and beverage products maintain high levels of hygiene and quality, thereby ensuring the health and safety of consumers.
