Dunnage bags or air bags are polypropylene bags filled with air (by means of a special valve) in various sizes that are used to stabilize cargo during transport. very useful in areas where the material to be transported is expensive and may be damaged or even compromised due to an unstable load. Dunnage bags, reusable up to 5 times, with a very small cost, make it possible to prevent the material being transported from being damaged due to lack of stability during loading.

Once used, at the destination, you can either reuse it or empty it out (via special tool given at the time of purchase) and thus send it back to the sender to be reused again.
various sizes available. for more info visit our google plus pages.
