Stowage

Checkstow is the Future

The new Checkstow dunnage air bag is designed for heavy duty use in the toughest conditions. The 1600 denier woven polypropylene outer gives this bag a clear lead in strength, resistance to water, and value for money compared with other materials, while the high density polythene liner ensures long term air retention and the possibility of re-use.

Heavy Duty Strength

The load an air bag can withstand depends on the strength of material used, quality of construction and the size of gap between the goods which it is used in. The narrower the gap, the less stress on the airbag, so the higher the pressure it will withstand and thus the greater the load. Also, the greater the contact area of the bag with the goods the better because this allows the pressure in the bag to be exerted on the goods rather than “wasted” stressing its own material. It follows that in a narrow gap the contact area will be greater than in a wide one, so the airbag will be more effective.

This is illustrated in the performance table for a 90 cm x 180 cm Checkstow.

The force available depends on the gap – the smaller the gap the better the level of protection against movement in tough conditions.
