This work aims to study the effect of a new packaging design with two functional films on the postharvest preservation of figs under ambient temperature (T = 25 ± 1°C, RH = 60 ± 5%). Water vapor permeable film, oxygen‐permeable film, and polyethylene terephthalate tray were used to make the packaging. During the experiment, the gas composition in the packaging, water loss rate, hardness, appearance, and nutrient contents of figs were tested and recorded. The atmosphere with low oxygen composition and high carbon dioxide concentration was formed in the packaging. New packaging could reduce the water loss of figs and slow down the decrease of hardness and the loss of nutrients. The shelf life of figs was prolonged to 4 days under ambient temperature by functional films, while the control group was only 2 days. Practical applications Two kinds of functional films (Water vapor permeable film and oxygen‐permeable film) were used to make a new packaging design for figs. The packaging could effectively prolong the storage time of fresh figs to 4 days under ambient temperature. It was of great significance to the storage, transportation, and sale of figs after harvest. Two kinds of functional films can also be used to preserve other fresh fruits and vegetables that are difficult to store.
