According to the perceptual engineering research paradigm, rock tea packaging design research framework of perceptual engineering is used as a guide to determine the typical samples and core perceptual vocabulary of rock tea packaging through various methods such as literature search, expert evaluation, KJ method, questionnaire survey, etc. The semantic difference method is used to quantify user perceptions and conduct principal component analysis to arrive at rock tea packaging presenting four core perceptual attributes: bright, environmentally friendly, exquisite and the mapping relationship between the core perceptual vocabulary and design elements was obtained through class category analysis to obtain a rock tea packaging design that fits the perceptual cognition of young consumers.
