A food package comprising a rigid plastic base tray having at least three compartments, the tray being covered by a flexible film which is airtightly sealed to flanges of the tray to airtightly or hermetically seal the respective compartments. A label structure integrally associated with the flexible film has opaque areas for label information and transparent areas for viewing the product. The label structure may be formed by separate pressure sensitive labels, by printing on the flexible film itself or by a shrink wrapped band with printing thereon. A structure associated with the bottom of the tray may provide rigidity, protect the bottom of the tray, provide an additional area for commercial information and/or provide a stand-up feature. The materials of the package may be selected to maximize recyclability.
