The express delivery business in China has maintained a rapid growth trend in recent years. According to the monitoring data from the State Post Bureau, as of April 29, 2024, the volume of express delivery business in China has reached 50 billion packages this year, 32 days earlier than in 2023. This data indicates that the express delivery business is continuously growing, and the growth rate is relatively fast. However, many cushion packaging materials use plastic materials such as EPS, which poses considerable pressure on environmental protection. Currently, the awareness of environmental protection in both China and the world is increasing significantly. As a more environmentally friendly alternative, paper-based cushion packaging can be expected to experience significant growth in the foreseeable future.
