FAQ

What are dunnage bags?

They are poly woven bags, constructed of level 1, level 2, level 3-4 or Level 5 of fabric with a polyethylene bladder used to restrain loads in rail cars, containers, trucks and ships. Dunnage bags are load securement materials that protect products from getting damaged in case of shifting during transportation.

Why use dunnage air bags versus other materials?

Dunnage bags are less expensive than other methods of securing and bracing loads with materials such as lumber, nails or plywood. 

How do I determine what size dunnage bag to use?

First, measure the void between your cargo. Then measure the distance from the floor to the top of the load. When the dunnage bag is inflated, it should contact 2/3 of cargo's surface area and should not be touching the floor or extending above the top of the load.

Do dunnage bags require any type of protection during use?

It is important to place cardboard, corrugated, honeycomb or similar materials on the side of the dunnage bag where there are rough surface or sharp objects.

What type of equipment is necessary to inflate International Dunnage bags?

Can dunnage bags be damaged during filling?

No, it can only be used as supplementary or load securement.

Can dunnage bags be used in air cargo?

IMPORTANT INFORMATION

AIR BAG PLACEMENT & SURFACE AREA CONTACT

  • No part of the air bag should stick out above the load being secured or on the front and back edge of the load. The air bag should not touch the floor.
  • Use corrugated or honeycomb shields to protect the air bag from sharp objects on both sides of the air bag. It is a recommended practice to check the air bag in 30 minutes to insure it is not leaking.
  • As a rule of thumb, 65% to 75% of the air bag surface on each side of the bag should have contact with the product.

SAFETY CONCERNS

  • Never block the rear of JetFlow air gun to over inflate.
  • Do not point the air gun at other persons or use to dust off your body.
  • Never place air bags on top of load or between the load and trailer door.
  • Bags should not be folded to fill up more of the void. Void fillers should be used to fill the void along with the air bag. Voids should not exceed 12 inches.
  • Wear safety equipment which should include safety glasses, gloves and any additional safety equipment required by your company.
  • Never stand in front of the air bag when filling; always stand to the side.
