In order to reveal the core literature, research focus and frontier trends in the field of international green packaging, Web of Science 2006—2015 core collection including 1 247 papers with the keywords related to “green package” or “green packaging” was classified and analyzed. By using the software CiteSpace III, the core literature, research focus and frontier trends in the field of international green packaging were studied with visualized analysis. The results show that: the top 10 cited contents of literature mainly concentrated on studies on packaging materials, while the research focus was on material study of film, nanocomposite and the establishment of packaging system to meet the requirements of sustainable development in mechanical property and reduction; the research frontiers could be divided into 3 stages, namely, scholars’ research efforts in characteristics of green packaging materials exceeded the characteristics of green packaging itself during 2006—2010, focuses were put on the harms of packaging to the environment or on specific packaging or design for some category of products during 2010—2012, while the focus was shifted into green packaging materials with the emphasis on generalized universal packaging from 2012 to 2015.
