How to select the Dunnage Bag Size?
Important Safety Consideration: At maximum void size, the air bags still has a 50% or more contact area. Exceeding the maximum void may result in premature air big failure. When the voids are greater than 24", use honeycomb panel or other filler to reduce the void. |  |
1.Standard Void:
As the container size and pallet size are standard size, when cargo put into container, the void and height are standard, too. For quick selection of the correct dunnage bag size, please refer to the following normal used sizes.
| Specification(mm)(W×L) | Void Height(mm) | Void Width(mm) | Usage Height(mm) |

| 800×1200 | 250 | 350 | 1100 |
| 900×1800 | 250 | 350 | 1700 |
| 1000×1800 | 300 | 400 | 1700 |
| 1000×2000 | 300 | 400 | 1900 |
| 1000×2200 | 300 | 400 | 2100 |
| 1200×2400 | 400 | 500 | 2000 |
2.Unstandard Void:
Measure distance from floor to top of load and select a bag size that is closest to the measured length.
Measure void between cargo and select a bag width that has about 2~3 times of the measured void.
