Dunnage Bags are inflatable air bags, which can be used to fill gaps (Voids) inside export containers, closed vans, trucks etc. The Outer layer is EXTENSIBLE KRAFT PAPER, while inner core is LLDPE film.To prevent any damage an un-inflated Dunnage bag is placed in voids between cargos. The bag is inflated with compressed air and exerts a force on the surface of the cargo, preventing any movement". This is called DUNNAGE. We at Secure recommend this packaging scheme which not only handles the transit challenges but also keeps the cargo in safe conditions be in Air Cargo or Shipping.
