PP Woven Dunnage Air Bag for Cargo Protection
PP woven dunnage air bag is a reusable, multi-layered bag made from kraft paper and PE film with an inner PA film layer, designed to secure cargo in trucks, trailers, and overseas containers. It inflates to fill voids and prevent load shifting, impact damage, and collapse during transport. The bag uses a multi-use valve for repeated inflation and deflation, and holds pressure up to 0.2 bar without leaking.
- Reusable and recyclable design reduces packaging waste per shipment
- Inflates to fill voids up to 60 cm, preventing load collapse in transit
- Multi-layer construction with PE and PA film resists punctures and air loss
- Multi-use valve allows repeated inflation and deflation for multiple shipments

Key Benefits
- Reusable and recyclable design reduces packaging waste per shipment
- Inflates to fill voids up to 60 cm, preventing load collapse in transit
- Multi-layer construction with PE and PA film resists punctures and air loss
- Multi-use valve allows repeated inflation and deflation for multiple shipments
- Lightweight and flat when deflated, so it does not occupy storage space
- Secures cargo up to 20 tons with consistent pressure across the load
Where It Is Used
- Securing heavy machinery and industrial equipment in FCL containers
- Stabilizing stacked cartons and pallets in road transport trucks and trailers
- Preventing shifting and impact damage during long-haul ocean freight
- Filling irregular voids between goods in LCL shipments
- Protecting high-value or sensitive cargo from compression during transit
Who It Is For
- Exporters shipping goods in FCL and LCL containers
- Third-party logistics providers managing freight in trucks and overseas containers
- Warehouses handling high-value or heavy industrial goods
- Manufacturers shipping large or irregularly shaped items
- Freight forwarders needing reliable, reusable load securing solutions
Problems It Solves
- Cargo shifting and collapse during road and ocean transport due to empty spaces
- Damage from impact or compression when goods are not properly braced
- Overuse of disposable void fill that increases waste and disposal costs
- Inconsistent load stability when using manual or non-reusable methods
- High storage cost for pre-filled or rigid packaging materials
Technical Features
- Multi-layer construction: kraft paper + PE film + PA film for air retention
- Heat-sealed construction with a multi-use valve for repeated use
- Working pressure limited to 0.2 bar (20 kPa, 2.8 PSI) to prevent over-inflation
- Inflates to fill voids from 100 mm to 600 mm depending on model
- Available in sizes from 500 mm to 1200 mm wide and 1000 mm to 2400 mm long
- Weight ranges from 0.3 kg to 1.49 kg depending on size and model

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.
| Foam blocks or wooden crates | Lighter, flat when deflated, reusable, and easier to store and transport |
|---|---|
| Single-use plastic air bags | Reusable and recyclable, reducing long-term packaging cost and waste |
| Strapping or wooden shoring | Fills irregular voids more effectively and protects against impact, not just compression |
| Paper void fill | Provides active pressure support and load stabilization, not just passive cushioning |
How to Use It
Place the deflated dunnage bag in the void space between cargo or pallets
Attach the air inflator to the multi-use valve and inflate to required pressure
Do not exceed 0.2 bar (20 kPa, 2.8 PSI) to avoid over-inflation
Check that the bag holds pressure and fills the space evenly
After transport, deflate and store flat for reuse or recycling
Inspect the bag before reuse for wear, punctures, or valve damage
