How do consumers identify differences among product packages on the shelves of a hypermarket? This
issue deserves our investigation. The current study aims to discover the factors in distinguishing bottle
packaging and the formula for displayability (ability to display). The research process is divided into
two stages. Stage One covers the ‘‘grounded concept of package design differentiation,’’ whereas Stage
Two covers the ‘‘statistical tests for packaging factors.’’ We have two findings. First, the participants’
design differentiation of packages is focused on the three differentiation factors: properties of commodity,
label design, and design of bottle shape. Second, completed regression analysis proves that their significant
levels are all p < .05. We therefore propose a regression model for the assessment of
differentiation design for bottle packaging = 0.717 properties of commodity + 0.708 design of bottle
shape + 0.795 label design 2.857. The three factors rank in importance as properties of commodity
> design of bottle shape > label design. These results can help marketing and design personnel compare
the difference in the package design of competitive products before they enter the market in
order to create differentiation and build brand identity
