An evacuable plastic storage bag comprises a pair of opposed walls that define, between them, an interior volume and a mouth. The bag has a Zip-locks TM closure for releasably sealing the mouth closed. The wall has a hole therein which is reinforced by an annular grommet-like plastic element. The element defines an aperture which is in communication with the interior volume of the bag and which is arranged in proximity to the closure. The wall has a plug of resiliently deformable plastic material for closing the aperture by forcing the plug into releasable engagement with the aperture. The plug and the element are disposed sufficiently close to the closure so that as the closure is pulled open, the plug is withdrawn, thereby obviating the need to withdraw the plug in a separate operation.
