In fierce market competition, product package design is one of the important means for companies to gain market share. Various expressions used in package design play an important role in creating emotional sympathy among consumers and encouraging consumption. Among them, minimalist design expression expresses images or objects with a basic structure, immediately recognizes the essence of the form, emphasizes, and minimizes it, making it easier to understand and accept. Furthermore, it enables form recognition that allows one to feel emotional autonomy by acquiring and performing playful functions. Accordingly, this study focused on studying the impact of minimalist expression attributes in package design on consumers' emotional perception. Through previous research and case analysis, the expressive properties of minimalism are summarized as 'simplicity and clarity' as formative elements and 'symbolism and environmentality' as semantic elements, and at the same time, according to the consumer PAD three-dimensional emotional model, emotional perception The dependent variables were set as ‘pleasure, arousal, and dominance.’ As a result of the analysis, it was found that in minimalism, the attributes of clarity expression all had a positive effect on consumers' pleasure, arousal, and dominance. In addition, it was found that the use of environmentality had a positive effect on consumer arousal and dominance. It should be noted that simplicity and symbolism play a positive role in stimulating consumer interest, but their impact on consumer arousal and dominance is not significant. This study fills in and verifies the research gap on minimalist expression in package design to a certain extent, making the study of a PAD consumer emotion 3D model richer and exploring the expression attributes of minimalism from a new perspective.
