Usability enhancement of take-out food packaging in its whole life circle was analyzed in this paper from the standpoint of businesses, shop assistants, consumer and environment, respectively. Results indicated that usability enhancement of take-out food packaging can be achieved by taking following measures: producing universal packages as soon as possible, reducing packaging decoration design, decreasing space occupation by using foldable packages, designing self-sealing and auto end-locked structure to facilitate enclosing and opening of packages, reducing quantity of packaging materials. These results provide packaging designers (or more broadly, design decision makers) with more advanced design concepts in the process of take-out food packaging design.
