A vacuum sealer is disclosed which makes use of a flexible flap (24.2) secured along one of its edges to a base plate (12.2). The base plate (12.2) on which the bag (B) to be evacuated and sealed is placed has a vacuum port (16.2) in it so that air can be sucked out from between the base plate (12.2) and flap (24.2). A groove (36.2) is provided in the base plate (12.2). This assists in keeping the bag mouth from being sucked shut before evacuation is complete. An anvil (26.2) and a sealer bar (14.2) form a weld across the bag adjacent its open mouth after evacuation.
