With the arrival of “national tide”, food packaging patterns with traditional cultural elements have frequently appeared in the marketing, but the marketing reactions are quite different. Previous studies have mostly focused on the impact of different external representations of traditional cultural elements (such as color) on consumer reactions, but less attention has been paid to the differential impact of the descriptiveness of traditional cultural elements. Therefore, this paper illustrates that the descriptiveness of traditional cultural elements has a positive effect on perceived healthiness with the mediating effect of pure authenticity, and thereby affects consumers’ purchase intentions. Furthermore, such effect is moderated by domestic (vs. foreign) brands, while health (vs. unhealth) product type can be used as the boundary condition of the above effect. This paper contributes to the literature by creatively putting forward the construct of the descriptiveness of traditional cultural elements and revealing its application effect in food packaging, as well as enriching and expanding the studies of Meaning Transfer Model in the fields of product packaging visual marketing and health consumption. In addition, it provides practical implications for enterprises by providing more detailed strategies of traditional cultural elements in packaging design.
