Dunnage Bags

Superior dunnage bags

Dunnage bags are specifically designed to secure and stabilize cargo in containers, closed rail cars, trucks and ships. They prevent both lateral and longitudinal movement and are much more effective in stabilizing cargo compared with wood blocking and bracing.

Dunnage bags are far more that just void fillers. They are a vital element of cargo safety, exerting tons of pressure to ensure cargo remains secure and damage-free in transit.

The best bag for a particular need depends on a number of variables such as void size, height of the cargo and specific shipping requirements. Our bags are available in a wide variety of sizes. Dunlash will advise on the most effective dunnage bag to match a customer’s individual requirements.

Tailored dunnage bag solutions 

Various types of dunnage bags can be used to stabilize cargo depending on the type of load and transport.

In general, there are two types of dunnage bags:
Paper and Polywoven.

Polywoven and paper dunnage bags have a higher resistance to puncture and moisture and maintain their strength during an entire trip, with independent tests showing them to provide the most secure solution.

There are numerous benefits to cargo securing which include quicker and easier securing in containers, railcars and ships as well as ease of use.

The Digital Fast Inflator needs only 14 seconds to fully inflate a 90x120cm woven dunnage with air, which saves time when securing a container.

Five levels of Dunnage Bags 

Dunnage bags are available in five performance levels which have been established by the AAR (Association of American Railroads):

  • Level one and two are mainly used in a container to fill empty spaces between pieces of cargo
  • Levels three, four and five are used to secure particularly heavy cargo like paper coils

We can provide all five levels of dunnage bags and our cargo securing experts can advise you on the correct level of dunnage bag for your type of cargo.
