About Lightweight – Dunnage Bags
The CheckStow dunnage air bag is designed for medium 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.
Certified to meet AAR standard level 4, with level 5 being available for special order


Applications
CheckStow is used for all types of cargo where a low cost airbag is required. It is equally suited for maritime break bulk cargos, container dunnage, and road or rail transport. CheckStow’s medium duty is able to match all dunnage requirements where value and strength are the priorities.
Caution: users should be aware that there is a risk of contamination should the bag be destroyed whilst in contact with a pulp cargo, thus care should be exercised.
Design
CheckStow follows the well-established engineering principle which says, “the simpler the better”. The outer re-enforcement layer of 1600 denier slit polypropylene is tubular woven and folded and sewn at the ends with polyester cloth re-enforcement.
This results in an outer layer of high strength with good puncture resistance. Air is retained by the high density 125-micron polythene inner which is co extruded and blow moulded with welded ends. The simple valve assembly is welded in place. Optimised materials make a highly cost effective, re-usable bag.

The company’s BS EN 9001 2015 quality assurance system is registered with SGS, a UKAS approved company.
