Abstract: A new fashion nano-packing was developed for the preservation of green tea. The O2 and RH transmission rate of the packing decreased 2.1%, 28%, while the longitudinal strength increased 24% in comparison with the normal packing. After 240 days, the remains of vitamin C, chlorophyll, polyphenol and amino acid increased 7.7%, 6.9%, 10.0% and 2.0% respectively in green tea higher with nano-packing than with normal packing.
