How to Double Stack Bulk Bags

One of the most significant problems with flexible intermediate bulk containers (FIBCs) that many companies face is the ability to store them efficiently and safely. Many companies use wooden pallets to store their bulk bags, but these are often wasteful, cost-prohibitive and might not provide the stability you need — and, honestly, you don’t actually need them. Use the following tips to multi-stack your FIBCs with the maximum safety and security as you prepare them for transport.

Bulk Bag Handling Instructions

To stack one bulk bag on top of another, use a forklift to lift the top FIBC by the provided loops and place it centered over the other. Lower it and then use the top bag to push on the bottom FIBC. This pushing creates a space in the top of the bottom bag for the top container to rest in, forming a “nest” for the top FIBC and locking the two into place. This system uses the bottom bag to stabilize the entire stack.

Multi-Stacking Your FIBCs: Pyramid and Supported Stacking

You’ll likely have more than two bags that need stacking, though, so there are two options for stacking multiple containers: the pyramid stacking method and the supported stacking method.

To use the pyramid stacking method, place a bottom layer of bags in the designated storage area and then set another layer on top of them, tiering them to create a pyramid. Remember that each layer will need to rest on at least four stacks. 

To use the supported stacking method, stack the bags evenly against at least two supporting walls.

While you can use the pyramid method when no supporting walls are available, supported stacking should be used whenever possible to ensure the maximum amount of stability. Try to find at least two retaining walls, but three is preferable — you can stack your bags higher and take up less space. 

Bulk Bag Stacking Tips

No matter which method you use, some stacking tips will remain the same. Remember the following as you double-stack your FIBCs:

  • Never push a bag into a stack, which can cause bag damage.
  • Even if you’re trying to remove a damaged FIBC, never pull or push from the middle of the stack — you might make the stack fall and damage more bags.
  • If your bags are leaning, if they have irregular shapes or if they can’t seem to handle the weight of additional containers, stop multi-stacking immediately and store the bags as a single layer.
  • Don’t stack your bags in standing water.
  • If stacking outside, remember to tie off the top closures and cover the stack with a waterproof covering.
