What Size Dunnage Bag Do I need?

What to consider.

Differente X-Pak Dunnage Bag sizes

Dunnage bags are a load securement staple within various Australian industries, particularly the Food and Beverage Industry, and keep cargo and other items from shifting during transit. They are also referred to as airbags, air cushions, and cargo inflatable bags. They come in a variety of different sizes, depending on how much space you must fill when you’re loading a container.

To determine what size airbag is suitable for your situation, you’ll want to consider the following factors: the void being filled and your cargo’s weight and transportation mode.

The void or ‘space’ you need to fill:

The void in a container is generally between pallets or between your cargo and the container walls and doors. The most effective way to fill this void and prevent movement is to use a bag as close to the void height and width as possible.

Key points to follow:

  • It’s not recommended you use an airbag greater than the void size. 
  • Fill to the required pressure and ensure you know the maximum gap a bag will fill.
  • When using cargo airbags to fill in gaps within a container, you must follow the manufacturer’s instructions.


As a rule, inflatable bags are effective in gaps ranging from 100mm to 500mm. If the surface of your cargo is uneven or sharp, it is recommended to utilise additional void fillers to create the best ‘form fit’ or flat surface as you can. The result is that the pressure exerted from the dunnage bag will be evenly distributed on your load and better protection during transport.

The Load Weight and Mode of Transport

Choosing the correct type of airbag is also dependent on the weight of the load and the transit method being used. The most common type of bag is a Level 1, which is used to prevent shifting while in a container for light cargo. However, Level 2 bags are available for heavier loads or transit methods that require higher levels of support. Other cargo bags can be used for sea containers, trucks, and rail transport, depending on how much support is needed for your cargo.

It would be best to consider the above factors when using airbags. Too many times, we see regular or low-level bags being used to secure low friction, heavy cargo in transport. This is a common issue, which often leads to significant product damage during transit. Using the correct level inflatable airbag will ensure your shipment’s smooth and damage-free delivery.
