EPS material has obvious advantages in packaging quality, working efficiency, and container utilization, etc., but it has not been widely used in the export packaging of KD parts of automobiles. In view of this phenomenon, a comprehensive research was conducted to analyze the problems existing in the export packaging of KD parts by EPS materials, and solutions were proposed from the aspects of reducing investment risk, optimizing the packaging design of EPS, improving the quality control system, recycling and recycling packaging waste, and improving the flame retardant performance of materials. In the process of popularization and application of EPS material, it is necessary to analyze and verify the specific packaging scheme to avoid new problems and affecting the quality of packaged parts.
