ABSTRACT:
An apparatus for packing perishable goods in which perishable foods are placed in a pre-formed base. A first flexible gas permeable plastic web is then placed over said goods, and a reduced pressure is established below the first web relative to that above the first web for effecting at least partial skin packing of the first web over the goods. A second plastic web is then placed over the first web, the goods and the base. A second web is then sealed to the base so as to provide a space between the first web and the second web. A gas is provided in the space between which can permeate through the first web toward the base to enhance preservation of the goods. The second web comprises a lid serving to retain the gas in the space.
