Inflatable Cargo Air Bags For Containers
Inflatable cargo air bags are multi-layered dunnage bags made from kraft paper and sealed with PE and PA films. They inflate on site to fill voids in containers and trailers, preventing load shifting, collapse, and impact damage during long-haul transport. Each bag is heat sealed and features a reusable valve for multiple uses. The bags are designed to withstand up to 20 tons of load and maintain pressure at working pressures up to 0.2 bar.
- Prevents load shifting and collapse in FCL and LCL containers during ocean and road transport
- Reusable and recyclable, reducing packaging waste per shipment
- Inflates on demand to fit any void size, from 100 mm to 600 mm
- Heat sealed chambers hold pressure without leaking during long transit
Include the carton size and the monthly volume and the reply will contain a format recommendation, not just a price.
Key Benefits
- Prevents load shifting and collapse in FCL and LCL containers during ocean and road transport
- Reusable and recyclable, reducing packaging waste per shipment
- Inflates on demand to fit any void size, from 100 mm to 600 mm
- Heat sealed chambers hold pressure without leaking during long transit
- Multi-layer construction with PE and PA films resists punctures and air loss
- Valve allows multiple inflations and deflations without damage
Where It Is Used
- Stabilizing stacked cartons of electronics or automotive parts during ocean freight
- Filling irregular voids between palletized goods in truck trailers
- Protecting fragile cargo like glass or ceramics from impact during long-haul transport
- Adjusting load support in containers with uneven or variable cargo heights
Who It Is For
- Exporters shipping goods in FCL and LCL containers across Europe, North America, and Asia
- Third-party logistics providers managing container load stability for multiple clients
- Manufacturers of industrial equipment, automotive parts, and heavy machinery
- Freight forwarders needing reliable, reusable dunnage for containerized shipments
- Warehouses handling high-value or fragile goods that require load protection
Problems It Solves
- Cargo shifting and collapse during ocean and road transport due to unsecured voids
- Damage from impact or vibration when goods are not properly braced in containers
- Overuse of wooden blocks or foam inserts that add weight and cost
- Inconsistent load protection when using loose fill or hand-cut materials
- High waste from single-use dunnage that cannot be reused or recycled
Technical Features
- Multi-layer construction: kraft paper with PE film outer layer and PA film inner layer
- Heat sealed chambers with reusable valve for multiple inflation cycles
- Working pressure limited to 0.2 bar (20 kPa, 2.8 PSI) to prevent over-inflation
- Available in sizes from 500*1000 mm to 1200*2400 mm to match various void dimensions
- Weight range from 0.3 kg to 1.49 kg depending on size, allowing accurate load planning
- Bear strength from 2.5 to 5.45 tons per bag, supporting loads up to 20 tons total

Materials
- Kraft paper for outer layer with high tensile strength
- PE film for outer layer to resist moisture and punctures
- PA film for inner layer to prevent air leakage
- Heat sealable film interface for strong, airtight chambers
- Reusable valve made for multiple inflation cycles
How It Is Made
Kraft paper and film layers laminated under controlled tension
Chambers formed and heat sealed using precision sealing bars
Valve integrated and tested for air retention
Final inspection of seal integrity and valve function
Bag deflated and packed flat for shipping
How It Is Checked
Incoming kraft paper checked for strength and uniformity before lamination
Seal strength tested on sample bags to ensure no air leakage
Valve tested for multiple inflation and deflation cycles
Final bag pressure tested to confirm no loss at 0.2 bar
Cartons inspected at container loading against packing list
Customisation Options
- Custom sizes available to match specific void dimensions
- Color options: brown or white kraft paper
- Logo printing on the bag surface on request
- Valve type can be adjusted for specific inflation tools
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 | Lighter weight, reusable, and easier to store and handle |
|---|---|
| Foam inserts | Reusable, recyclable, and more adaptable to irregular voids |
| Paper dunnage bags | Higher puncture resistance and better air retention due to PA film layer |
| Plastic air bags | More sustainable with kraft paper outer layer, though less flexible in shape |
How to Use It
Place the deflated bag in the void space between cargo or against the container wall
Attach the inflation tool to the valve and inflate to the recommended pressure
Check that the bag fills the space evenly and does not bulge or over-inflate
Use multiple bags to stabilize large or heavy loads across different zones
Deflate and store flat after use for reuse in future shipments

Inflatable Cargo Air Bags For Containers Questions
What is the maximum pressure I can use to inflate these bags
Do not exceed 0.2 bar (20 kPa, 2.8 PSI) to avoid over-inflation and damage.
Can I reuse the same air bag multiple times
Yes, the multi-use valve allows repeated inflation and deflation without damage.
How do I know which size to order for my container
Choose a bag size that matches the void height and width. Refer to the model size chart for guidance.
Is the bag recyclable after use
Yes, the kraft paper and film layers are recyclable. Check local recycling rules for mixed materials.
Can you print our logo on the bag
Yes, we can print your logo on the bag surface. Send artwork and the size you need.
