Fruits undergo water evaporation and volatilization during long time storage. Fruit mesh sleeves are commonly used to package fruits to maintain their shape and prevent collisions. However, if the fruit is stored in the net sleeve for too long, the water will gradually evaporate, resulting in the weight of the fruit being reduced.

Fruits undergo natural ripening and decay during prolonged storage. Certain fruits will gradually soften and become heavier as they ripen, but over time they will begin to rot or lose moisture, resulting in weight loss. In this case, the weight of the fruit in the fruit netting sleeve will be reduced accordingly.
