A packaging system for perishable food products (36), especially for meat products discharging residual blood and other natural fluids, comprising a tray (12; 32; 89; 120) and an outer tray closure film (38) spanning the perimeter of the tray (12; 32; 89; 120), wherein the tray (12; 32; 89; 120) possesses structural features for transmission of draining fluids away from the meat product (36) extending the shelf-life of the packaged meat (36) while avoiding the usual "browning" appearance. Instead, the natural redness and appetizing appearance or "bloom" properties of the meat product (36) are maintained for enhanced customer acceptance. The outer film (38) preferably incorporates at least a sufficient amount of a biostatic and/or biocidal agent. The tray (12; 32; 89; 120) includes an elevated meat supporting porous film (14; 34; 60; 70; 88; 118), and a reservoir below the porous film (14; 34; 60; 70; 88; 118) for collecting descending fluids. The descending fluids are managed by a series of elevations (24; 54; 84; 112) and lower channels (22; 56; 122) for collection/retaining the fluids in supporting relationship with the porous film (14; 34; 60; 70; 88; 118). |
