Laminated PP Dunnage Air Bags Description
Laminated PP Dunnage Air Bags are designed to fill empty spaces between cargo units and stabilize loads during transportation.
The laminated PP structure combines the strength of woven polypropylene with the sealing performance of a PE inner bladder, creating a durable void-filling solution for export cargo.
Compared with Kraft paper and standard PP woven airbags, laminated PP airbags offer better moisture resistance, higher durability, and longer service performance in demanding logistics environments.
Laminated PP Dunnage Air Bags Technical Specifications & Application Guide
Performance Grades
| Grade | Maximum Working Pressure | Construction | Recommended Application |
| Level 1 (Standard Export) | 20 KPa / 0.20 Bar / 2.9 PSI | Laminated PP Outer Layer + PE Inner Bladder | Ocean Containers & General Export Cargo |
| Level 2 (Heavy Duty) | 40 KPa / 0.40 Bar / 5.8 PSI | Reinforced Laminated PP + PE Inner Bladder | Rail Freight & Heavy Industrial Cargo |
| Level 3 (Extreme Duty) | 60 KPa / 0.60 Bar / 8.7 PSI | Extra Reinforced Laminated PP + PE Inner Bladder | Steel, Heavy Machinery & High Dynamic Load Applications |
Available Sizes
| Width | Common Lengths |
| 60 cm / 24″ | 90 cm / 120 cm |
| 90 cm / 36″ | 120 cm / 180 cm / 210 cm |
| 120 cm / 48″ | 180 cm / 210 cm / 240 cm / 300 cm |
| 150 cm / 60″ | 240 cm / 300 cm |
Custom sizes and bespoke dimensions are available upon request to fit your specific logistics requirements.
Void Space Selection Guide
| Air Bag Width | Maximum Ocean Container Void | Maximum Truck Transportation Void |
| 60 cm | Up to 20 cm | Up to 15 cm |
| 90 cm | Up to 30 cm | Up to 25 cm |
| 120 cm | Up to 40 cm | Up to 35 cm |
| 150 cm | Up to 50 cm | Up to 45 cm |
Important Safety Guideline
For optimal performance and safety, the void space should generally not exceed 35–40% of the air bag’s flat width.
For larger voids approaching 50 cm, additional load securing methods such as bulkheads or empty pallets are recommended.
Laminated PP Dunnage Air Bags Applications
Paper Rolls & Printing Materials
Filling gaps between rolls and container walls to prevent shifting and impact damage during long-distance transportation.
- Chemical Drums & IBC Containers
Stabilizing cylindrical and liquid containers by reducing movement caused by vibration and transportation forces.
- Steel Products & Metal Coils
Providing additional support for heavy industrial cargo during ocean, rail, and truck transportation.
- Machinery & Industrial Equipment
Securing irregular-shaped and high-value equipment by improving load stability inside containers.
- Construction Materials & Palletized Goods
Filling empty spaces between pallets and cargo units to reduce movement during export shipments.
Laminated PP Air Bag Structure
Laminated PP Woven Outer Layer
Provides superior moisture resistance and abrasion protection against rough cargo surfaces, pallets, and container walls.
High-Performance PE Inner Bladder
Maintains stable internal pressure and delivers excellent long-term air retention performance throughout transportation.
How It Works
Step 1 – Position
Place the deflated air bag into the void space between cargo units.
Step 2 – Inflate
Inflate the air bag safely using compressed air and a compatible Tensipack inflation tool.
Step 3 – Expand
The bag expands evenly and distributes pressure across adjacent cargo surfaces.
Step 4 – Secure
The expanded air bag fills the gap and helps maintain cargo stability during transportation.
High-Efficiency Valve Options
Standard Valve
- Economical and reliable solution
- Easy inflation and deflation
- Excellent long-term sealing performance
- Suitable for most export cargo applications
Turbo Valve
- Ultra-fast inflation speed

Quality Verification & Strict Testing
To ensure consistent performance in demanding transportation environments, every production batch undergoes rigorous quality verification.
24-Hour Air Retention Test
Each production lot is pressure-monitored for a full 24 hours before packaging.
Burst Strength Verification
Routine destructive pressure testing verifies strict compliance with internal safety requirements.
Valve Leakage Inspection
Every valve component is tested to ensure reliable long-term sealing performance.
Material Inspection
Incoming laminated PP fabric, PE inner bladders, and valve components are inspected before entering production.
