Dunnage Bags – Frequently asked questions

What is a container airbag/dunnage bag?

Dunnage bags are used to stabilize cargo in transport and therefore prevent product damage. They are placed in a void and inflated with air to restrict load shift in transport. Other common terms for dunnage bags are: Container airbags, Woven dunnage bags, Air bag packing, Container dunnage, Inflatable air bags. A dunnage bag’s holding force on a product is the bursting pressure of the bag multiplied by the surface area which the bag is in contact with.


Why should I use a dunnage bag?

The global economy spends millions of dollars every year on damaged goods, airbags prevent this. Properly manufactured dunnage bags are designed to preserve the integrity of products in transit and top load shift (the most common cause of damage). Product damage is often expensive and can also pose a risk to personnel.


Are all dunnage bags pretty much the same?

No. First is the supply of raw materials. X-Pak makes its own materials to ensure we’re the only vertically integrated manufacturer globally. Our competition source raw material from third parties. This often means lack of control over quality and can create inconsistencies with the finished product.


Can I re-use my dunnage airbag?

Yes. Although priced at a consumable level (as most clients don’t see these back!), our airbags have a valve that will inflate/deflate bags. This is fitted on all bags from Level 0 right through to Level 5 bags. Many clients throughout Australia re-use our bags between production sites.


Where are X-Pak dunnage bags made?

The core range of X-Pak dunnage bags are manufactured in Turkey. Turkey has a strong history in weaving products so it’s no coincidence! Some of our custom dunnage bags are also manufactured at our site in Germany along with custom lashing and other various dunnage solutions.


Can you make custom sizes?

Yes. X-Pak works with many clients in Australia with specialised dunnage bags. As the generic range of dunnage bags in Australia is small, we’d always prefer to ensure your cargo is safe by providing the correct bag size and weight for the job. In the past, many dunnage bag suppliers will simply provide you with a stock bag in hope that it will work.


What temperature can a dunnage bag withstand?

Our common range of bags will withstand up to minus 30 degrees celcius. Any colder than that, the bag outer becomes brittle after a few hours and loses pressure. Container shipments often experience a fluctuation in temperature so its important to ensure we run the numbers through our calculators to reduce any loss in pressure.
