The modern IBC design that we are familiar with today, which typically consists of a large, rigid container with a pallet base and a valve for dispensing, was developed by the Japanese chemical company, Daihatsu Kogyo Co. (now known as Daihatsu Diesel MFG. Co., Ltd.). The company introduced their "Daijumbo" container in 1974. This container had a capacity of 1000 liters (about 264 gallons) and was designed for transporting chemicals.

Around the same time, other companies in Europe and the United States were also working on similar bulk container concepts, but Daihatsu's design was one of the pioneers in the industry and significantly contributed to the development and popularization of IBCs.

Since then, many other companies worldwide have entered the IBC manufacturing market, offering various designs, materials, and capacities to cater to different industries and applications. The IBC industry has seen continuous growth and innovation, solidifying its place as a fundamental solution for bulk liquid and granulated material transportation and storage.

Key Features of IBCs

Pallet Base: IBCs are equipped with a sturdy pallet base, facilitating easy handling and transportation using forklifts or pallet jacks. This feature ensures smooth movement within the facility or during loading and unloading processes.

Valve or Tap: An essential component of an IBC, the valve or tap located at the bottom allows controlled dispensing of the contents. Various valve types are available, enabling precise flow control to prevent wastage and spillage.

Gasket and Seals

Gasket and Seals: To maintain the integrity of the container and prevent leaks during transport, IBCs are fitted with high-quality gaskets and seals. These ensure a tight and secure closure, safeguarding both the contents and the environment.

Sealants used in IBC containers are carefully chosen to withstand harsh environments and ensure the integrity of the container's contents. As IBCs may be exposed to sunlight and various challenging conditions during transportation and storage, the sealants possess specific features to meet these demands. Some essential features of sealants used in IBC containers are:

UV Resistance: The sealants are formulated to resist degradation and damage caused by ultraviolet (UV) radiation from sunlight. UV-resistant sealants prevent premature aging, cracking, or weakening of the seals, ensuring the container remains leak-proof.
