The research explores the need for improvements in the excessive packaging practices of the mooncake industry in response to new regulations introduced by China’s State Administration for Market Regulation. Through a combination of literature review and theoretical analysis, this paper examines three key aspects of sustainable design: economic, social, and environmental. It then proposes a sustainable packaging design framework specifically for mooncake packaging. Despite the increasing awareness of sustainability, mooncake packaging still faces challenges such as excessive use of materials, over-large packaging gaps, and costly materials. By analyzing the framework, this paper advocates for mooncake companies to incorporate sustainability from economic, social, and environmental perspectives, thus transforming the industry toward more sustainable practices.
