Abstract
A packaging apparatus for forming, filling and gas flushing, evacuating and sealing packaging materials to produce low-oxygen content packages. The apparatus contains a conveyor for transferring packaging containers from a container forming work station to various intermediate work stations to an evacuating and sealing station and thence to an exit station of the packaging machine. A protective gas-confining cover is provided over the path followed by the containers, and gas-flushing means are provided for the filler materials and the containers.
