A processor tray is provided for maintaining plastic film wrapped thereabout in a taut state. The tray is unitarially formed with a plurality of sidewalls, a corne r joining each pair of sidewalls, and a base. A flange is formed to extend outwardly and downwardly from uppermost portions of the sidewalls and the corners preferably in the range of 15.degree.- 35.degree.. Additionally, the flange may be formed with varying widths about the perimeter of the tray. Th e bast may be either formed flat or, alternatively, the base may be formed with three concentric regions to define a concavity, with one region being planar and raised relative to the bottom of the tray.
