  • Patent number: 4377061
    Abstract: A method for wrapping commodities comprising supplying a pair of spaced apart layers of air-impermeable wrapping material and securing the layers together transversely along a leading end. A commodity is inserted between the layers to lie adjacent the secured leading end. The side or sides of the layers are secured together. The layers are then perforated in a transverse row adjacent the commodity on its side opposite the other side adjacent the leading end. The layers are then sealed transversely between the commodity and the row of perforations to completely seal the commodity within the layers. Prior to completely sealing the commodity, but after perforating, the space surrounding the commodity between the layers is evacuated. The invention also covers an apparatus for carrying out the method.
