A container liner is a sealed, form-fit bladder that lines the inside of a shipping container. It isolates your product from the steel walls and residue, so you can move bulk solids the way you would in a silo — cleaner, faster and cheaper than thousands of individual bags.

Any dry bulk that moves in containers and benefits from a clean, bag-free load.

Grains, pulses, seeds and feed moved in bulk with minimal loss.

Resins, pellets and powders shipped clean and dry.

Fertilizer and other dry solids in sealed liner.
The liner is a single form-fit bladder; cargo enters through the top and leaves through a bottom sleeve or valve at the container doors.
