Abstract: A flip tray is provided that includes a transparent, compartmentalized container body and a flexible sealing sheet sealed to partition walls and to the peripheral rim of the compartmentalized container body. Plant material with active respiratory activity such as fruits and vegetables are disposed in the compartments of the transparent container body. Each of the compartments exchanges respiratory gases through the micro-perforated sealing sheet individually in a controlled manner. A tray having a completely flat bottom is secured to the container body so as to underlie the flexible sealing sheet and includes peripheral vent conformations.
