A new method and system for establishing, and optionally maintaining, a desired atmosphere for perishable or atmosphere-sensitive goods during their storage and/or transportation. In one embodiment, a conveyor is used to move a pallet with goods from station to station. A mechanical arm at a sheeting station lifts goods from a pallet while one or more sheets are placed between the goods and the pallet. A bottom plate with fingers having hollow tubes holds the pallet while the pallet is being wrapped and enclosed. A portable manifold may also be connected to the hollow tubes and a controller samples and adjusts atmosphere inside the pallet via the portable manifold.
