Inflatable Dunnage Bag – Marine Cargo Securing Solution

Our inflatable dunnage bags are essential for securing cargo inside containers and ship holds. Designed to fill empty spaces and brace shipments, these heavy-duty bags prevent load shifting during transit, protecting both goods and vessel structures. Ideal for break-bulk, containerized cargo, and ro-ro operations.

Each bag features an outer layer of reinforced kraft paper and an inner air bladder constructed from tough, air-tight polyethylene. The bag inflates quickly with standard pneumatic equipment, expanding to conform tightly to the cargo surface. Engineered for high burst resistance, it provides reliable pressure distribution and minimizes the risk of damage from sudden weight changes.

Available in multiple sizes to meet a variety of bracing requirements, these inflatable dunnage bags are a cost-effective and efficient solution for maritime and shipping professionals. Manufactured to comply with international cargo securing guidelines.

Frequently Asked Questions

What is an inflatable dunnage bag used for?

Inflatable dunnage bags are placed in empty spaces inside containers or ship holds. When inflated, they press against the cargo to prevent load shifting, securing boxes, pallets, and other goods in place during transport.

How do I inflate the dunnage bag?

Use a standard compressed air nozzle or pneumatic gun compatible with the bag's inflation valve. Inflate gradually to the recommended pressure (typically 0.2–0.3 MPa). Do not over-inflate beyond the specified burst pressure.

Can these bags be reused?

Though designed for single-use applications, they can often be deflated and reused for lighter loads. However, inspect thoroughly for damage before reusing.

What sizes are available?

Common sizes range from 500×1000 mm to 1200×2000 mm. Custom sizes can be produced upon request for specific cargo securing needs.
