Strong materials allow a safe working pressure of 0.3 bar (3 psi). This ensures there is enough safety margin to allow for changes in ambient temperature. Increases will make the airbag pressure go up and decreases will make it go down. Checkstow’s heavy duty construction allows a margin of safety not possible with other bags which risk bursting as temperatures increase or getting too soft as they decrease.

The forces available can be very high. Consideration must be given to whether the cargo and packaging can withstand the inflation pressure chosen.
