Fruit is easy to be damaged and hard to keep fresh. In order to reduce the loss during storage and transportation, the manufacturer will fill the packaging box with ice bags, foam, paper pads and other materials. However, some merchants add too much and too heavy filler, which makes the actual weight of the fruit far lower than the said gross weight and makes the fruit packaging "empty and fat". When you buy a box of mangoes of about ten kilograms, the padding paper in it takes up two or three kilograms. Not to mention the increase in transportation costs, it is obviously unreasonable for consumers to pay for packaging materials at the price of fruits. The fruit packaging is "empty and fat". Some of the producers are worried about the damage of the fruit during transportation, which will affect the reputation, and they lack more effective packaging materials and technologies. In order to be safe, the "three layers inside and three layers outside" of the fruit packaging are excessively protected. Some businesses deliberately use more packaging and filling materials to increase the gross weight and seek more profits. Therefore, to solve the problem of "puffiness" in fruit packaging, we need to improve packaging technology and perfect market supervision. First, we should reduce the amount of fruit packaging by improving packaging technology and clarifying relevant standards. For example, some places have explored the technical measures for packaging and preservation of fruits and vegetables, formulated technical specifications for graded packaging and preservation, and provided technical guidance for product packaging and preservation for grassroots application units. It is worth popularizing to reduce packaging without reducing the basic functions of preservation and damage prevention. Second, it is suggested to strengthen the coordination and supervision of the relevant departments of the fruit producing area and the distribution area, and urge the fruit producers and dealers to clearly mark the packaging, filler weight and net weight of the fruit when they sell the fruit, so as to operate in good faith and not mislead the consumers.
