What Are Kraft Dunnage Airbags?
Kraft dunnage airbags are inflatable void fillers made from multiple layers of high-strength extensible kraft paper with a polyethylene inner liner that helps retain air pressure. They are placed between cargo loads inside trucks, railcars, sea containers, and intermodal units to fill empty space and reduce cargo movement during transit.
Paper dunnage air bags are widely used in commercial freight because they provide reliable void fill, simple installation, and cost-effective cargo protection. They require minimal handling during loading and unloading, making them ideal for high-volume shipping operations where bags are replaced after each shipment cycle.
