Heavy Duty Inflatable Dunnage Air Bags, AAR Certified Cargo Securement Void Fill Bags for Ocean Container Truck Rail Intermodal Shipping, Prevent Cargo Damage

Dunnage Air Bags are heavy-duty inflatable bags used to secure, brace, and block cargo inside shipping containers, railcars, trucks, and ocean vessels. They are placed in the voids between cargo units (e.g., pallets, cartons, drums, or machinery) and then inflated to fill the empty space. Once inflated, they create a tight, cushioned barrier that prevents shifting, collision, and damage during transit.

Made from multiple layers of kraft paper and polyethylene (or woven polypropylene for reusable types), these bags offer a cost-effective and efficient alternative to traditional bracing methods like wooden beams, blocking, or strapping.
