Dunnage Bags help to absorb impact and vibrations in cargo during transportation and can be reused several times. Dunnage Airbags are used to secure cargo and create a bulkhead during transit. Dunnage Airbags are great void fillers to prevent movement and absorb impacts in a sea container, rail car, truck, vessel, or intermodal. Dunnage Airbags combine IN-LINER (also known as the bladder or balloon) which holds the compressed airtight at high-pressure levels, and OUT-LINER (the cover) to give the Dunnage Airbags the shape, stability, and enormous strength. To ensure perfect tightness even under high pressure, all our Dunnage Airbags IN-LINER are made of specially extruded polyethene (PE-mixture).
