During the "Double Eleven" period, not only colleges and universities, but also community express delivery was popular. The workload of these couriers is several times that of normal times. According to the forecast of the State Post Office, more than 1.5 billion packages may be generated during the "Double Eleven" this year. It is estimated that the annual express delivery volume will reach 40 billion pieces. If calculated according to the population of 1.3 billion, that is equivalent to an average of more than 30 express deliveries per person. The huge volume of express delivery has also brought about a large consumption of express packaging. In 2015, China's express delivery industry consumed about 9.922 billion packing boxes and 8.268 billion plastic bags. The total length of adhesive tape used was 16.985 billion meters, which could make 425 circles around the equator of the earth.
