If you are new to using Dunnage Bags, here are some important Do’s and Don’ts tips to make sure you use them correctly:
1. Use the correct filling tool and make sure that it is equipped with the right connector.
The valves on Dunnage Bags are like the charging ports on your mobile phone, different manufacturers put different valve types on their bags. Make sure that your inflator gun fits the valve on your dunnage bags.

5. Don’t use 2 dunnage bags next to each other or fold bags.
This just does not work. The bags will slide.

Using dunnage bags that are taller than your cargo will create a ballooning effect, as the air will always travel to the area of least resistance.
7. Don’t use dunnage bags for transport by air.
The cabin pressure fluctuates too much to keep a consistent air pressure inside the bags. This can result in the bags to deflate or explode.
8. Do not overinflate your dunnage bags.
Never over inflate dunnage bags as this will likely cause them to explode.
9. Use correct strength level for your cargo and mode of transport.
There are 6 levels (including level 0) of dunnage bags. This article provides insight selecting the right level dunnage bag.
10. Never position dunnage bags between cargo and container doors.
This can build up force at the door, creating a dangerous situation upon opening of the container doors.
