Nowadays, packaging standardization has been playing a key role in the sustainable development in society, and is an important approach to upgrading the international competitiveness of enterprises. Great achievements have been made in packaging standardization in China, but there is still some catch-up to do when compared with developed countries. Based on a questionnaire based survey, by means of exploratory factor analysis (EFA) and descriptive statistics, factors affecting packaging standardization are obtained which include material selection, economic benefits, recovery methods, functional requirements and technical elements. Meanwhile, the major difficulties in the implementation of packaging standardization are also located which include administrative factors, industry factors and enterprises’ inner factors. Based on these analyses, specific suggestions are presented for the strengthening of packaging standardization.
