A valve for a dunnage bag including an inner part having a flange that is laminated to the inside surface of the bag and an outer part having a flange that is laminated to the outside surface of the bag providing that the bag can be inflated/deflated by air passing through both parts and a hole in the bag. The outerpart is a bowl which is stretched away from the bag when the bag is being inflated and which collapses against opening in the inner part to seal the bag and prevent air loss.
