PP Woven Dunnage Bag
PP woven dunnage bag is a reusable, multi-layered air 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. One bag replaces multiple wooden blocks or foam wedges, reducing packing time and material handling.
- Reusable and recyclable design reduces packaging waste per shipment
- Multi-layer construction with PE and PA film resists punctures and air loss
- Inflates to fill voids up to 600 mm, preventing load collapse in transit
- Multi-use valve allows repeated inflation and deflation for multiple uses

Key Benefits
- Reusable and recyclable design reduces packaging waste per shipment
- Multi-layer construction with PE and PA film resists punctures and air loss
- Inflates to fill voids up to 600 mm, preventing load collapse in transit
- Multi-use valve allows repeated inflation and deflation for multiple uses
- Lightweight at 0.3 kg to 1.49 kg per bag, reducing freight cost per load
- Fits variable spaces from 100 mm to 600 mm void fill, adaptable to different cargo sizes
Where It Is Used
- Securing stacked cartons in a 20-foot container to prevent shifting during ocean transit
- Stabilizing heavy machinery parts in a trailer to avoid impact damage on road hauls
- Filling irregular voids between pallets of electronics in a dry freight container
- Preventing collapse of stacked ceramic tiles during long-distance shipping
- Protecting high-value industrial components in a truck trailer from vibration and shock
Who It Is For
- Exporters shipping goods in FCL and LCL containers who need load stability
- Third-party logistics warehouses managing high-volume freight with variable cargo sizes
- Trucking and freight forwarders securing loads in trailers and semi-trailers
- Manufacturers of industrial goods, machinery, and heavy components that ship long distance
- Warehouses using reusable packaging to reduce waste and disposal costs
Problems It Solves
- Cargo shifting in transit causes impact damage and product loss
- Wooden blocks and foam wedges are single-use and increase waste and disposal costs
- Manual packing of fill materials slows loading and increases labour time
- Inadequate void fill leads to load collapse under stack pressure in containers
- Non-reusable packaging increases material cost per shipment over time
Technical Features
- Multi-layer construction: kraft paper + PE film + PA film for air retention
- Multi-use valve allows repeated inflation and deflation without leakage
- Maximum working pressure of 0.2 bar (20 kPa / 2.8 PSI) to prevent over-inflation
- Load-bearing strength from 2.5 T to 7 T depending on size and inflation
- Inflated void fill range from 100 mm to 600 mm to match cargo gaps

Materials
- Kraft paper for outer layer with high tensile strength
- PE film inner layer to prevent air leakage
- PA film inner layer for enhanced puncture resistance and air retention
- Multi-use valve made from durable, reusable material
- No recycled content in the film layers; all materials are virgin
How It Is Made
Kraft paper and film layers laminated under controlled pressure and temperature
Multi-layer web fed into a bag forming machine with precise sealing
Valve insertion and heat sealing at the designated position
Final bag cut to size and inspected for seal integrity
Packaged in bulk for container loading with weight and count verified
How It Is Checked
Incoming kraft paper and film checked for thickness and strength before lamination
Seal strength tested on sample bags to confirm no air leakage under pressure
Weight and dimensions verified per model before packing
Final cartons checked at container loading against the packing list
Customisation Options
- Custom sizes available to match specific void dimensions
- Custom valve type or location on request
- Logo or brand marking on the bag surface via printing
- Material grade adjustments for higher puncture resistance or longer reuse
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 | Reusable, lighter, and easier to store; no risk of splinters or damage to cargo |
|---|---|
| Foam wedges | Reusable and recyclable; no single-use waste and lower long-term cost |
| Plastic air bags | Better recyclability and lower environmental impact; suitable for buyers with sustainability targets |
| Manual packing of loose fill | Faster setup and consistent void fill; reduces labour time and variability in packing quality |
How to Use It
Place the dunnage bag in the gap between cargo or pallets
Attach the inflation hose to the multi-use valve and inflate to fill the void
Do not exceed 0.2 bar pressure to avoid over-inflation and damage
After shipment, deflate and store flat for reuse in future loads
Inspect the bag before reuse for any punctures or seal damage
