The reduction and greening of the packaging industry have become an inevitable trend for the future. At present, there is still a certain degree of excessive packaging in China’s commodity packaging, which is mainly manifested by the inappropriate protection function, storage and transportation function, and promotion function. Excessive packaging harms the environment, the rights and interests of consumers. Furthermore, it affects the market order and social conduct. The relevant laws and regulations that restricting excessive packaging in China were introduced. The reasons for excessive packaging caused by legal regulations and supporting measures, traditional consumer concepts and market competition, design level and technical means were analyzed. Some feasible ideas and strategies for eliminating excessive packaging have been proposed, such as establishing a legal system, levying excessive packaging taxes, refining packaging classification standards, improving packaging design concepts, and strengthening technical research and development.
