For varieties that are easier to color, you can choose single-layer paper packaging bags, which are gray, green and other colors on the outside and black on the inside. The outer bag of the double-sided paper bag mainly plays a protective role. When the fruit is mature, the outer layer of the paper packaging bags is removed, and the colored translucent paper of the inner layer of the paper bag is conducive to better coloring of the fruit.
