What is AtmetOne+?

The common dunnage air bags on the market are paper dunnage air bags which are made of one of more layers of Kraft papers and have a polyethylene inner. 
Dually dunange air bag uses Kraft paper-Polywoven laminated layer as the outer bag. This outer layer combines the advantages of both Kraft paper rigidity and high strength polywoven. As a result, AtmetOne+ is extremely durable and higher resistance against punctures and moistures.

The inner bag is made of 5-layer co-extruded high strength polyethylene (PE) which can keep the dunnage bag leak free for a long period of time.
AtmetOne+ is most suitable for land and oceans shipment through container or truck load.

How to prevent over-inflation of dunnage bag?

Our ProAir Venturi Inflator has a self-pressure regulator designed to prevent over-inflation of bags. When the desired pressure is reached, the air flow will redirects itself out through the back of the inflator avoiding over-inflation. This eliminates the risk of bag bursting during inflation.

• Measure void between cargoes and select a bag width that has about 2~3 times of the measured void.
