Dunnage air bags, also known as container air bags, void fill inflatable bags, are essential cargo securing packaging materials for sea, rail and truck transportation. Our JahooPak dunnage air bags are divided into two mainstream types: kraft paper dunnage bags and PP woven dunnage bags. Equipped with high-speed one-way inflation valves, they can be quickly inflated with air guns or manual pumps to fill gaps between cargo inside containers, trailers and rail carriages. They firmly lock goods to prevent shifting, collision, tilting and damage during long-distance shipping. All our air bags pass AAR certification, support customized sizes, printing logos and low MOQ OEM orders, widely applied in furniture, electronics, metal parts, food, chemical and general cargo logistics.
