Packaging solutions in the world used in the industrial sectors are safe, efficient, and cost effective. The Intermediate Bulk Container (IBC) is one of the solutions which have revolutionized the storage and transport of bulk materials.

IBCs are known to be very durable, have high capacity and are multifunctional in the sense that they have found use in most industries including the chemicals industry, food industry, pharmaceutical industry, agriculture sector, petrochemical industry, waste water treatment and many more.

This is the ultimate guide to intermediate bulk containers with all the information about the type, design, materials used, benefits, usage, safety, cleaning, reconditioning, lifecycle, sustainability effect and other key purchasing decisions.

What Is an Intermediate Bulk Container?

An Intermediate Bulk Container (IBC) is a reusable or single-use, industrial grade container that is used in the safe storage, handling, and transportation of liquids, semi-liquids, viscous, powders, pastes, and granulated substances.

The design of IBCs allows them to be very space-saving due to their high volume capacity, and their footprint size is comparable to a pallet.

Common Features of IBCs

• Cube-shaped design
• Capacity between 500 to 3000 liters
• Stackable frame
• Pallet-compatible base
• Top filling cap and bottom discharge valve.
• Constructed of economical substances (HDPE, steel, stainless steel, composite).

Why Are They Called “Intermediate”?

They fall between:

• Small drums (200L)
• Large tank containers (20,000L+)

Hence the name intermediate bulk container.

History & Evolution of Intermediate Bulk Containers

The solution to a significant industrial problem was the invention of IBCs:

The way to carry more bulk of items without the inefficiency of small drums and the rigidity of large tanks.

Key Milestones

• 1960s-1970s: Metal IBCs on chemicals were invented.
• 1980s: HDPE plastic IBCs were introduced.
• 1990s: Composite caged IBCs gain international standard.
• 2000s: Flexible IBCs (FIBCs) transform the process of handling dry bulk.
• 2020s: IBCs with RFID sensor tracking and internet of things sensors come in.

In the current day, IBCs have become indispensable in industries in which safety, efficiency and compliance are paramount.

The FIBC full form is Flexible Intermediate Bulk Container.

• Flexible – The bag is soft-sided and foldable
• Intermediate – It carries 500–2,000 kg (medium/bulk capacity)
• Bulk – Used to store/transport bulk materials

The FIBC is a high capacity, robust, industrial bulk bag constructed of a woven polypropylene fabric, forming a bag that is used to facilitate, store and transport dry, flowing substances such as grains, powders, granules, sand, fertilizer, chemicals and building products.

They are lightweight, strong, recyclable and have a heavy capacity of up to 2,000–3,000 kg and therefore they are one of the most preferred bulk packaging solutions in the world.

This elaborate manual covers the definition of FIBC, varieties, manufacturing, dimensions, advantages, usage, safety standards and reasons why industries rely on the use of the bags.

What is an FIBC?

A Flexible Intermediate Bulk Container (FIBC) is an industrial all-purpose container to carry a bulk of material between 500 kg to 2000 kg.

Woven PP (polypropylene) fabric is used to make these bags and this provides the bag with high strength, flexibility, and durability.

The industries in which Fibc is mostly used include:

• Food & agriculture
• Chemicals
• Pharmaceuticals
• Construction
• Mining
• Plastics & resins
• Fertilizers

Their design allows easy lifting with forklifts, cranes, or pallet mechanisms, making them ideal for storage and transport.

Why Are FIBCs Called “Flexible Intermediate Bulk Containers”?

Every word in its entirety is meaningful:

1. Flexible

The bag material is of tough woven fabric which can be bent without snapping.

2. Intermediate

It is not too large or too small like sacks that are used by industries.

3. Bulk

Intended to transport high loads (in many cases more than 1 ton).

4. Container

It holds and carries such materials as a container though in a light form.

The name is ideal in describing the product.

Common Names for FIBC Bags

FIBCs can also be referred to as:

• Bulk Bags
• Jumbo Bags
• Super Sacks
• Big Bags
• Tote Bags
• WPP (Woven Polypropylene) Bulk Bags
