PP Woven Dunnage Air Bags Specifications & Selection Guide
Performance Levels
Tensipack PP Woven Dunnage Air Bags are available in different performance levels to meet various cargo securing requirements, from standard truck transportation to heavy-duty rail and industrial applications.
| Performance Level | Maximum Working Pressure | Material Construction | Recommended Application |
|---|---|---|---|
| Level 0 (Truck Grade) | 18 KPa / 0.18 Bar / 2.6 PSI | Heavy-Duty PP Woven Outer Layer + High Performance PE Inner Bladder | Truck transportation and lighter intermodal cargo |
| Level 1 (Standard Export) | 20 KPa / 0.20 Bar / 2.9 PSI | Premium PP Woven Outer Layer + High Performance PE Inner Bladder | Ocean container shipping and general export cargo |
| Level 2 (Heavy Duty / Rail) | 40 KPa / 0.40 Bar / 5.8 PSI | Reinforced PP Woven Outer Layer + High Performance PE Inner Bladder | Rail freight, heavy machinery and steel products |
Safety Factor & Technical Support
All Tensipack PP Woven Dunnage Air Bags are designed and manufactured with a 3:1 safety factor, ensuring the structural burst threshold exceeds the rated working pressure by at least three times.
For different cargo conditions, Tensipack provides technical support including:
- Cargo securing recommendations
- Air bag size selection guidance
- Performance verification records
- Technical data sheets
- Laboratory test reports
For ultra-wide 150 cm air bags used in larger void spaces, operating pressure should be controlled according to Tensipack technical guidelines to ensure safe and effective performance.
Air Bag Width & Void Space Selection Guide
Selecting the correct air bag width is essential for achieving maximum surface contact and balanced pressure distribution.
The recommended air bag size depends on:
- Cargo type
- Void space dimension
- Transportation method
- Loading condition
| Air Bag Width | Maximum Recommended Void (Ocean Container) | Maximum Recommended Void (Truck) | Available Length |
|---|---|---|---|
| 60 cm / 24″ | Up to 20 cm / 8″ | Up to 15 cm / 6″ | 90 / 120 / 150 cm |
| 90 cm / 36″ | Up to 30 cm / 12″ | Up to 25 cm / 10″ | 120 / 150 / 180 / 210 cm |
| 120 cm / 48″ | Up to 40 cm / 16″ | Up to 35 cm / 14″ | 150 / 180 / 210 / 240 cm |
| 150 cm / 60″ | Up to 50 cm / 20″ | Up to 45 cm / 18″ | 180 / 210 / 240 / 300 cm |
Cargo Securing Principle
For optimal load stabilization performance, the recommended void space should generally not exceed 35%–40% of the air bag flat width.
For larger gaps approaching 50 cm (20″), especially when using ultra-wide air bags, combining dunnage air bags with additional blocking materials such as bulkheads or recycled pallets can provide improved cargo stability.
PP Woven Dunnage Air Bags Applications
PP Woven Dunnage Air Bags are widely used for cargo stabilization and void filling in container, rail, truck and intermodal transportation. They help reduce cargo movement, prevent transit damage and improve load security.
Container Shipping
For export containers, helping stabilize cargo against vibration and shifting during ocean transportation.
Rail Freight
Suitable for high-vibration environments, providing reliable protection for heavy and industrial cargo.
Truck Transportation
Helps secure palletized and general cargo against braking forces and road vibration.
Heavy Machinery & Industrial Cargo
Designed for large, heavy or irregular cargo requiring additional load stabilization.
Chemical Drums & IBC Containers
Suitable for cylindrical and liquid containers requiring puncture-resistant cargo protection.
Quality Verification & Testing
To ensure reliable performance during transportation, Tensipack implements strict quality control procedures throughout the manufacturing process, from incoming material inspection to final product verification.
The PP woven fabric, PE inner bladder and valve components are carefully inspected before production. During manufacturing, key performance checks including air retention testing, valve sealing verification and burst strength testing are performed to ensure product reliability, durability and consistent quality.
Before shipment, finished dunnage air bags are inspected for appearance, sealing performance and packaging condition to ensure they meet Tensipack quality requirements and provide stable cargo protection in demanding transportation environments.
Quality Control Process Includes:
- Raw Material Inspection
- Air Retention Verification
- Valve Sealing Test
- Burst Strength Test
- Final Product Inspection
