Top Quality High Pressure Air Dunnage Bag & Dunnage Air Bag
Air dunnage bags are multi-layered, reusable bags made from kraft paper and PE film that inflate on site to secure cargo in trucks, trailers, and overseas containers. They prevent load collapse and impact damage during transport by filling voids and maintaining pressure over time. Each bag is heat sealed with a multi-use valve for repeated use, and the structure uses a PA film inner layer to prevent air loss. The bags are designed for high-pressure use up to 0.2 bar and can support loads up to 20 tons.
- Prevents load collapse and impact damage in road and ocean freight by filling voids with pressurized air
- Reusable and recyclable, reducing packaging waste and long-term cost per shipment
- Multi-layer construction with PA film inner layer maintains air pressure over time
- Multi-use valve allows inflation and deflation for multiple shipments

Key Benefits
- Prevents load collapse and impact damage in road and ocean freight by filling voids with pressurized air
- Reusable and recyclable, reducing packaging waste and long-term cost per shipment
- Multi-layer construction with PA film inner layer maintains air pressure over time
- Multi-use valve allows inflation and deflation for multiple shipments
- Fits irregular spaces in containers and trailers without custom tooling
- Lightweight when deflated, so storage and transport of empty bags take minimal space
Where It Is Used
- Securing heavy machinery and industrial equipment in FCL containers during ocean export
- Stabilizing stacked cartons and pallets in truck trailers to prevent shifting
- Filling large voids in oversized containers where standard dunnage is insufficient
- Protecting high-value goods during long-haul transport where load integrity is critical
- Supporting cargo in mixed-load shipments where different product heights create uneven gaps
Who It Is For
- Exporters shipping heavy or irregularly shaped goods in FCL and LCL containers
- Third-party logistics providers managing freight in road and ocean transport
- Manufacturers of industrial equipment, machinery, and large components requiring securement
- Warehouses handling high-volume outbound shipments with variable carton sizes
- Freight forwarders needing reusable, space-saving solutions for container loading
Problems It Solves
- Cargo shifting and collapse during transit due to unsecured voids in containers and trailers
- Overuse of wooden blocks or foam inserts that add weight and cost
- Inconsistent load stability from manual packing with loose fill or padding
- High disposal costs and waste from single-use dunnage materials
- Inflexible packaging solutions that cannot adapt to variable cargo dimensions
Technical Features
- Multi-layer construction: kraft paper + PE film outer layers, PA film inner layer for air retention
- Heat-sealed multi-use valve for repeated inflation and deflation
- Working pressure up to 0.2 bar (20 kPa / 2.8 PSI), not exceeding safe limits
- Fits voids from 100 mm to 600 mm, depending on model and size
- Weight range from 0.3 kg to 1.49 kg per bag, depending on size
- Supports loads up to 20 tons when properly inflated and positioned

Materials
- Kraft paper with high tensile strength for outer layers
- PE film for moisture and puncture resistance on outer surface
- PA film (polyamide) as inner layer to prevent air leakage
- Heat-sealable materials for consistent sealing during manufacturing
- Multi-use valve made from durable, reusable plastic
How It Is Made
Kraft paper and PE film laminated into outer layers using heat and pressure
PA film applied as inner layer to enhance air retention
Bag pattern cut to size using precision die-cutting
Heat sealing performed on all edges and valve area to ensure integrity
Valve installed and tested for air retention and reusability
Final inspection for seal strength, material consistency, and dimensional accuracy
How It Is Checked
Incoming kraft paper and film materials checked for thickness, strength, and moisture content
Seal strength tested on sample bags to ensure no air leakage under pressure
Dimensional checks performed on each batch to match model specifications
Customisation Options
- Custom sizes outside standard range upon request
- Logo or branding printed on outer kraft paper layer
- Custom valve type or placement for specific inflator compatibility
- Different film grades available for higher puncture resistance or moisture barrier
How It Compares With the Alternatives
Where another material is the better answer we say so, because a returned shipment costs more than a lost order.
| Wooden blocks | Lighter, reusable, and easier to store; no risk of splinters or damage to cargo |
|---|---|
| Foam inserts | Reusable and recyclable; no waste after one use; better for large voids |
| Paper dunnage | Higher pressure resistance and longer air retention; suitable for heavy loads |
| Plastic air bags (non-reusable) | Reusable design reduces long-term cost and environmental impact |
How to Use It
Place the deflated dunnage bag in the void space between cargo or between pallets
Connect the multi-use valve to an air inflator or hand pump
Inflate until the bag is firm and fills the gap completely
Do not exceed 0.2 bar pressure to avoid over-inflation and damage
After shipment, deflate and store flat in a dry, cool place for reuse
Inspect the bag before reuse for seal damage or punctures
