Keep cargo secure through every mile.

Summit Dunnage manufactures polywoven and kraft paper dunnage airbags for dependable load securement across a range of shipping environments.

Placed in the empty spaces between pallets, boxes, and other loads, dunnage bags create a stabilizing force that helps reduce shifting, movement, and impact damage. They are built for strength, efficient inflation, and practical installation by loading teams.

Our team can help evaluate your application, recommend the right product, and develop a loading plan around your cargo, void size, and transportation mode.
