ABSTRACT:
A vacuum packaging apparatus suitable for use in packing fluid foodstuffs or the like into bags. In a chamber are disposed a pair of support members having surfaces opposite relative to each other which are individually formed with suction holes. When a bag is fed between the pair of support members, vacuum is applied through the suction holes so that opposite surfaces of the bag are sucked into the opposite surfaces of the support members. Subsequently, the support members are moved away from each other, whereupon the mouth of the bag is opened. An object is fed into the mouth-opened bag for being vacuum packed therein. The resulting vacuum packaged product is supported in position between the pair of support members, being thereby flatly shaped.
