From the perspective of the reinforcement effect that empathy theory has on children's food packaging design, the current application of this theory in this field primarily focuses on empathy. It aims to achieve a two-way emotional connection between children and parents through the concrete expression of children's psychological empathy and the implicit transmission of parental values. The analysis of the application scenarios of empathy theory in children's food packaging design reveals three major breakpoints in children's psychological empathy, three major obstacles in the transmission of parental values, and technical bottlenecks in emotional transmission functions. To overcome these limitations, it is necessary to enhance the precise adaptation of children's psychological empathy, build a trust system for the transmission of parental values, and innovate the technical application models for emotional transmission.
