Posted Date: 30 Mar, 2021

What are Dunnage Bags?

Dunnage bags are also popular by the name of air cushions or airbags. These are used to stabilize and secure any cargo. The dunnage bags were invented in the year 1970. These bags basically come into place as a lucrative and convenient cargo stabilization in the ocean going vessels, sea containers, and closed railcars. So, the main intention behind developing the dunnage bag was to secure the road trips. This special invention was able to lower approximately 25% of the road accidents involving trucks by offering cargo security!


How it works?

The technology behind the dunnage airbags is the backbone of its working. They consist of a few closed chambers which are made up of air-filled elastic films. When the truck or the vehicle is at rest, the static load generated by the package contents lie upon the cushioning. At the moment the load becomes dynamic, the extra load is absorbed by the cushion.

The amount of the inflation air can be customized according to the properties of the package contents. Generally, the dunnage bags are available in different sizes and designs. The cushioning styles can also be varied from edge and corner cushioning to tubular cushioning.
