The packaging system can be readily prepared for immediate transport and aging, retail display and consumer freezing. The present system comprises a relatively rigid tray (8) which is sealed with a flexible gas impermeable cover (22), said tray being provided with a resealable septum valve (30). The tray is also preferably provided with a plurality of protrusions or mounds (14) so as to facilitate gas flow and contact with a given perishable product. The atmosphere in the packaging system may be modified to inhibit bacterial decay of the product and/or to enhance its apearance.
