What is the difference between an IBC and a drum?
Scale, handling and how the product comes out — and which one suits you depends on how you use the material, not just how much you buy.
A drum is a single container of roughly 30 to 55 gallons handled with a truck or a dolly. An IBC is an intermediate bulk container of roughly 275 to 330 gallons, sits on its own pallet base and usually discharges through a bottom valve. One IBC replaces several drums, but changes how the material is received, stored and drawn down.
Handling
Drums are moved individually and are simple to split across production lines or customers. An IBC arrives as one unit, needs the clearance and equipment to move a full pallet load, and usually stays put while material is drawn from it.
Getting the product out
Most IBCs discharge from the bottom through a valve, which suits continuous or repeated draw-down. Drums are pumped, tipped or scooped depending on the head style and how viscous the product is.
Consumption pattern
The deciding question is usually how fast the material is used once opened. A large open container that sits half-full for weeks can be a quality problem in a way that a sealed drum is not.
Empties
Both formats have an empty problem. Rigid IBCs are bulky to return or store. Drums are smaller but numerous. Nesting drums, collapsible IBCs and carton IBCs each attack that from a different angle.
What to consider
- How much material is consumed per week once a container is opened
- Whether the receiving site can handle and store a full IBC
- Cleaning and cross-contamination between batches
- What happens to the empty container, and who pays for it
- Whether a liner would let the same outer container serve several products
