High Load Capacity PP Woven Air Bag with over 9 Ton Compression Resistance for Heavy Cargo

Product Detail

What is the pp woven air dunnage bag

A PP woven dunnage bag is essentially an industrial-strength airbag used for cargo stabilization. It features a robust two-part construction:

Outer Shell (Out-liner): Made from high-strength woven polypropylene (PP) fabric. This tough outer layer provides shape, durability, and resistance to compression, moisture, and punctures.
Inner Bladder (In-liner): Typically made from a co-extruded polyethylene (PE) or polyamide (PA) film. This airtight inner bladder holds the compressed air that provides the securing pressure

How to use the air dunnage bag for protecting the cargo

Placement: Position the deflated dunnage bag into the void or gap you want to fill between the cargo and the container wall (or between separate cargo sections).
Inflation: Inflate the bag using compressed air. You will typically need an air compressor, an inflation device, and a pressure gauge to do this safely. Many bags are equipped with a one-way check valve that allows for rapid inflation and prevents air from escaping once the hose is removed.
Tighten and Secure: Inflate the bag until it feels tight and immovable in the void space. It’s crucial not to over-inflate, as this can damage your cargo or burst the bag. The recommended working pressure is often around 0.2 bar (approx. 3 PSI).
Deflation and Removal: Once the cargo has reached its destination, the bag is deflated by opening its valve. After deflation, it can be removed and inspected for potential reuse.

Why need use the air dunnage bag

Superior Cargo Protection: By firmly bracing cargo, they reduce the risk of product damage from shifting, vibrations, and collisions during transit. This helps minimize “unsellables” and associated replacement costs.
Cost and Labor Savings: They are a cost-effective alternative to using lumber or other bracing materials. They are quick to inflate and deflate, which saves valuable loading and unloading time.
Environmental Friendliness: PP woven materials are strong, lightweight, waterproof, and 100% recyclable. The ability to reuse them multiple times also helps reduce waste, promoting sustainable logistics practices.
Versatility and Ease of Use: They can be customized in size and shape to fit various gaps and cargo types. Their lightweight nature makes them easy to handle and position without heavy equipment.
