The Impact of Packaging Visual Design Elements on Impulse Buying Behavior in E Commerce: A Study of Cosmetic Products

Abstract

This study investigates the impact of visual packaging design elements specifically color and graphics, shape, material, and product information on impulse buying behavior among Generation Z consumers in the Western Province of Sri Lanka within e-commerce settings. Using a quantitative approach, data were collected via a structured online questionnaire from 461 respondents. The data were analyzed using SPSS software, employing descriptive statistics, correlation analysis, regression modeling, and reliability and validity tests. The results reveal that packaging color and graphics, shape, and material have a significant positive influence on impulse buying, whereas product information does not show a significant effect. The findings highlight that emotionally engaging and visually appealing packaging elements are more effective in stimulating unplanned purchases than rational, information-based cues. Grounded in the Stimulus Organism-Response (SOR) model, the study demonstrates that external visual stimuli evoke internal emotional responses, which lead to impulsive buying decisions. These results emphasize the strategic importance of integrating attractive and sustainable packaging features in digital retail to appeal to Generation Z consumers, who are highly responsive to aesthetic and emotional stimuli. This research contributes to the limited literature on consumer behavior in South Asian online markets and offers practical insights for e-commerce marketers and product designers seeking to enhance impulse purchase rates through packaging design.
