What is Caustic Soda Liquid?

Caustic soda liquid 48% is a colorless, transparent liquid primarily composed of sodium hydroxide. It is highly corrosive and strongly alkaline, widely used in industries such as chemical manufacturing, papermaking, textiles, and detergent production. Caustic soda solution should be stored in a cool, dry, and well-ventilated area, away from direct sunlight and isolated from acidic and flammable substances. It is typically packaged in plastic drums or specialized storage tanks, and transportation must comply with relevant regulations to ensure the integrity of the packaging. Through proper use and management, caustic soda solution can play a crucial role in various industries, enhancing production efficiency and product quality.

These containers, known as Intermediate Bulk Containers (IBC), are specifically designed for storing and transporting caustic soda liquid. IBC containers are typically made of high-density polyethylene (HDPE), which has excellent chemical resistance, effectively preventing corrosion from the caustic soda solution.

The external metal frame, made of galvanized steel or stainless steel, provides additional mechanical strength, ensuring the stability and safety of the containers during handling and transportation.


The standard capacity of an IBC container is usually 1000 liters (approximately 1 ton), and its modular design makes it easy to stack and store, saving space and transportation costs. These containers are also equipped with sealed lids and bottom discharge valves, making them convenient to operate and use, and ensuring that there are no leaks during transportation.
