The Significance Of Dunnage Bags In The Shipping Industry

Dunnage bags are also popular by the name of air cushions or airbags. These are used to stabilize and secure cargo loads in trucks, rail cars and containers. The dunnage bags were first used about 1970. These bags basically come into place as effective and convenient cargo stabilization devices for the ocean going vessels, sea containers, and closed railcars. So, the main intention behind developing the dunnage bag was to secure the cargo loads in transit. This special invention was able to lower approximately 25% of the damage during transportation involving trucks by bracing and cushioning the cargo loads.

The technology behind the dunnage airbags is the backbone of its working. They consist of a closed chamber which are filled up by compressed air. When the truck or the vehicle is at rest, the static loads are braced by air cushions . When the truck is moving, the load becomes dynamic and the shocks generated are absorbed by the air cushions.

The amount of the inflated air can be customized according to the properties of the cargo load content. Generally, the dunnage bags are available in different sizes and working pressures. The container stuffing configuration depends on the type and size of the cargo loads. The dunnage bag supplier can provide advice on the most suitable type of dunnage bag for the specific cargo loads .
