A multi-channel flat valve assembly comprises multiple fluid channels which are effectively defined within the multi-channel flat valve assembly by means of laterally or transversely spaced heat-sealed regions. Accordingly, when the dunnage or cargo air bag is inflated, whereby the forces acting upon the oppositely disposed plastic sheets defining or comprising the flat valve assembly would tend to cause separation of the oppositely disposed plastic sheets with respect to each other and cause the flat valve assembly to attain an OPENED state, the disposition or presence of the heat sealed regions defining the multiple fluid channels effectively intercepts the propagation of such forces whereby the flat valve assembly tends to remain in its CLOSED state so as to effectively preserve the INFLATED state of the dunnage or cargo air bag, or considered alternatively, the dunnage or cargo air bag does not undesirably or inadvertently achieve a DEFLATED state.
