The present invention relates to a drawer assembly and a refrigerating and freezing device with the drawer assembly. The drawer assembly comprises a cartridge defined a drawing space and a modified atmosphere film assembly, an accommodating cavity is defined in a top wall of the cartridge, the accommodating cavity is communicated with the drawer space; the modified atmosphere film assembly is mounted in the accommodating cavity, and the modified atmosphere film assembly is provided with a modified atmosphere film and an oxygen-enriched gas collecting cavity, so that when the pressure of the oxygen-enriched gas collecting cavity is less than the pressure of the accommodating cavity, oxygen in air of the accommodating cavity penetrates the modified atmosphere film to the oxygen-enriched gas collecting cavity, so as to obtain a gas atmosphere with rich nitrogen and lean oxygen, facilitating for fresh keeping of foods.
