What Is a Dunnage Air Bag and When Should You Use One?
What is a dunnage air bag
A dunnage air bag is an inflatable bag placed in the void between cargo units, between one pallet and another, or between cargo and the container wall. Once inflated to the right pressure, it forms a stable cushion that restricts cargo movement throughout the transport journey.
In essence, this is a dunnage solution — a general term for materials used to fill voids and protect cargo during storage, handling, and transport.
When to use a dunnage air bag
Dunnage air bags are typically considered when: palletized cargo leaves voids between pallets inside a container; loose or large units risk shifting horizontally; long-haul or ocean routes involve prolonged vibration; or a customer has recorded repeated damage or toppling at the destination.
Whether to use one, and which type, depends on the cargo type, weight, void size, and transport method — which is why CARGENTRA always recommends an assessment step before proposing a solution.
Frequently Asked Questions
Can dunnage air bags be used for trucks, or only containers?
Dunnage air bags can be used for containers, trucks, and intermodal transport, depending on the product type and level. The specific choice should be based on an actual assessment of the shipment.
Can dunnage air bags be reused?
Reusability depends on the bag's condition after deflation and the specific product's guidance. Careful inspection is recommended before deciding to reuse a bag.
