A method for long term storage of a bulk commodity utilizes a flexible, low gas-permeability sheet material enclosure in which the bulk commodity is hermetically sealed. The atmosphere in the sealed flexible sheet material enclosure is substantially evacuated to establish a vacuum therein. The vacuum is maintained during at least a portion of the long term storage of the bulk commodity. At least a portion of the bulk commodity is removed from the flexible, low gas-permeability sheet material enclosure by opening a hermetic seal therein.
