| 4-Ply (Heavy Duty) | 40 KPa / 0.40 Bar / 5.8 PSI | Multi-Layer Kraft Paper Construction + PE Inner Bladder | Heavy industrial cargo, machinery, steel products, and rail transportation |
Void Space & Size Selection Guide
Selecting the correct air bag width is critical for safe cargo stabilization.
| Air Bag Width | Container Shipping | Truck Transport | Common Lengths Available |
| 60 cm / 24″ | Up to 25 cm / 10″ | Up to 20 cm / 8″ | 90 cm / 120 cm |
| 90 cm / 36″ | Up to 40 cm / 16″ | Up to 35 cm / 14″ | 120 cm / 180 cm / 210 cm |
| 120 cm / 48″ | Up to 50 cm / 20″ | Up to 40 cm / 16″ | 180 cm / 210 cm / 240 cm |
Important Cargo Securing Principle
To maintain maximum stabilizing efficiency, the void space should generally not exceed 35%–40% of the air bag’s flat width.
For oversized gaps, heavy cargo, or special loading configurations, please contact Tensipack for technical recommendations.
Kraft Paper Dunnage Air Bag Applications
- Container Shipping
Stabilizing palletized cargo, cartons, drums, and industrial products during ocean transportation.
- Truck Transportation
Reducing cargo movement caused by vibration, braking, and road conditions.
- Rail Freight
Providing additional load support for long-distance railway transportation.
- Paper Rolls & Printing Materials
Preventing heavy rolls from shifting and reducing impact damage during transit.
- Machinery & Industrial Cargo
Supporting irregular and heavy cargo inside containers and trailers.
How It Works
- Place the deflated air bag into the void space between cargo units.
- Inflate the bag using compressed air through the valve system.
- The bag expands and conforms to the cargo surfaces.
- The resulting pressure locks cargo in place.
- The air cushion absorbs vibration, impact, and transportation forces throughout transit.
