For bracing trailer loads to avoid damage from shifting, Air-Lock truck dunnage bags offer a sustainable, security-sensitive solution. Constructed of a see-through material for enhanced visibility, the dunnage provides a low cost alternative to kraft paper or vinyl (PVC) bags. Features include a highly conforming structure and cling effect when used with stretch films to reduce product migration. They inflate with a valve and seal closed quickly.
