The diaper packaging currently available in the market tends to be generic, predominantly featuring photos of infant models and lacking vibrancy and childlike appeal. With the increasing youthfulness of the mother and baby consumer demographic, there is a growing interest in products with unique and aesthetically pleasing packaging that aligns with current trends. Consumers are looking for visually appealing and fun designs, all while ensuring product quality. In response to this demand, we have designed the diaper and pull-up packaging for Mumu Fini with a focus on cuteness, childlike charm, and vibrant colors. Diapers: We have identified a direct and relatable connection between the product and the user—the buttocks. Our design features prominently illustrated animal buttocks, creatively expressing and interpreting this connection. Pull-ups: Similarly, we have honed in on the most intuitive and distinctive feature of pull-ups—the act of pulling up. This expression is transformed into the theme of holding hands, with an extension into various scenes depicting children holding hands, as well as children holding hands with parents.
