ABSTRACT:
This invention provides an apparatus for over-wrapping or bulk packaging of commodities on a pallet or the like supporting surface. The apparatus comprises a supporting surface on which commodities are adapted to be over-wrapped or bulk packaged with a sealable flexible wrapping material, a movable enclosure surrounding the supporting surface and forming an open-topped chamber with said supporting surface. The aforesaid chamber is adapted to receive flexible packaging material, and the movable enclosure is movable relative to the supporting surface to permit access to the supporting surface. Means for gripping and engaging opposed portions of the flexible wrapping material are provided as are means for evacuating air from the flexible wrapping material after the commodities have been inserted therein. Means are also provided for sealing the flexible wrapping material in said chamber to form a seal across the wrapping material.
