Dunnage bags are structures inflated with pressurized gas to secure cargo in place during transport by filling the voids between the cargo and the walls or floor of the shipping container.
Dunnage bags are made of 3 major components, an inflatable layer, an outer covering and some means to inflate and/or deflate the inner layer. The inflatable layer typically consists of an elastic material like polyethylene and the outer layer can be something made up of a sturdy material which has a bit of inelastic properties.
To use a dunnage bag, simply place it between the cargo and the container’s wall or floor and inflate it using a pump or air compressor. The bag will fill the space and create a cushion to prevent the cargo from shifting and bouncing during transport. This is particularly helpful for fragile or delicate items that could be damaged in transit.
Dunnage bags come in a variety of sizes and shapes to fit different shipping containers and cargo. They can also be reused as long as they are in good condition. Overall, a dunnage bag is a cost-effective solution for securing cargo
