The vacuum machine usually works in two phases, which are normally referred to as suction and welding. First, take the bag you want to vacuum seal and put it in the machine. In the first phase, the suction, the air present in the bag, is therefore sucked by a small pump that manages to remove all the oxygen present. In the next phase, the sealing of the sealing bar of the machine is heated and passed on the bag. And this will allow it to close hermetically so that it can no longer enter the air. If other containers, specific for vacuum storage, are used, the hermetic seal will already be incorporated, and this phase can be avoided.
