400MM Width Air Cushion Film
Air cushion film is a continuous roll of pre-sealed chambers that remain flat until inflated at the packing bench. Each chamber is sealed separately, so a puncture only affects one cushion, not the entire roll. The film is made from 100% new raw material, ensuring strong seals that hold pressure during long transit. A single 300 m roll replaces bulky pre-formed void fill, freeing up warehouse space and reducing packing time.
- One 300 m roll inflates on demand, eliminating the need to store pre-formed void fill
- Pre-sealed chambers mean a puncture only affects one cushion, not the whole pack
- Film made from 100% new raw material ensures strong seals that hold pressure through long transit
- Cushions are formed at the bench, so fill matches the actual void size in each carton
Include the carton size and the monthly volume and the reply will contain a format recommendation, not just a price.
Key Benefits
- One 300 m roll inflates on demand, eliminating the need to store pre-formed void fill
- Pre-sealed chambers mean a puncture only affects one cushion, not the whole pack
- Film made from 100% new raw material ensures strong seals that hold pressure through long transit
- Cushions are formed at the bench, so fill matches the actual void size in each carton
- Lower packed weight than moulded foam or paper void fill cuts dimensional freight charges
- Available in 400 mm width for small to medium cartons, compatible with standard packing machines
Where It Is Used
- Filling the void around electronics and circuit boards before courier shipment
- Protecting glass containers and ceramic items in export cartons
- Cushioning cosmetics and precision instruments during long-distance transport
- Securing hardware kits and spare parts in oversized cartons
- Blocking and bracing bottled or jarred goods inside export packaging
Who It Is For
- E-commerce fulfilment centres packing mixed SKUs into standard cartons
- Third-party logistics warehouses that need void fill without dedicated storage space
- Exporters shipping fragile goods in FCL and LCL containers
- Contract packers replacing loose fill and hand-cut foam on manual packing lines
Problems It Solves
- Pre-formed void fill occupies warehouse space that could hold saleable stock
- Loose fill migrates in transit and leaves products unprotected on arrival
- Hand-cut foam and crumpled paper slow the packing bench and vary in quality
- Over-filled cartons attract dimensional weight charges on courier and air freight
- Manual packing of void fill leads to inconsistent cushioning and higher damage rates
Technical Features
- Continuous roll of pre-sealed chambers inflated and heat sealed on an air cushion machine
- 20 um film gauge balances puncture resistance against material cost per cushion
- Each roll runs 300 m so a single roll change covers a full packing shift
- 400 mm web width covers small to medium cartons used in e-commerce and export
- Rolls ship two per carton at 4.9 kg, which allows accurate container loading planning
- Chambers can be torn by hand to match the exact void size in each package

How It Is Checked
Incoming resin checked as 100% pure virgin material before extrusion
Seal strength sampled during the sealing run so weak chambers are caught on the line
Sample rolls inflated and held to confirm the cushions do not go soft
Roll length and web width verified at winding
Cartons checked at container loading against the packing list

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.
| Loose fill chips | Cushions stay where the packer places them and do not migrate to the top of the carton in transit |
|---|---|
| Traditional bubble wrap on the roll | Ships flat and is inflated on site so it needs a fraction of the storage space for the same protected volume |
| Paper void fill | Lighter per carton, though paper is the better answer where the buyer needs a plastic-free pack |
| Cut foam inserts | No tooling and no SKU-specific inserts, at the cost of a less precise fit for very heavy items |
How to Use It
Load the roll onto the air cushion machine and thread the film past the sealing bar
Set the machine width to match the film so the chambers inflate evenly
Run a short length first and check the seals hold before packing production
Place cushions on the carton base, around the product, then top off the remaining void
Store unused rolls flat and away from direct heat
