The characteristics of ecological packaging are mainly reflected in three aspects: the packaging environmental performance based on whole life-cycle assessment, the improved resource utilization rate of energy as the center, the raw material without destroying the ecology. Ecological packaging material is one of the key factors in the development of ecological packaging. The development trend of ecological packaging materials could be directed at six fields: non-toxic packaging material, recyclable packaging material, packaging material reduction, original ecologicalization of packaging materials, degradable packaging materials, nanocrystallization of packaging materials.
