A vacuum packaging machine for producing sealed vacuum packages is disclosed which includes an improved sealing station. The sealing station has a heatable sealing member and a backing member for co-operation therewith, and deflector means are associated with the scaling member to deflect the air and moisture sucked off from the evacuating chamber of the evacuating and sealing station in operation in order to direct said air and moisture away from the sealing member to avoid contact therebetween, so that the air and moisture contained therein will substantially not be heated by the sealing member which is heated in operation. As a result, the moisture contained in the air sucked off from the evacuating chamber will not expand under the action of heat from the sealing member, and a substantially better vacuum will be achieved with the same capacity of the evacuating system.
