Tea storage tests were carried out by using five typical packaging materials, which were LDPE, BOPP/PE, BOPP/PET/PE, PT/AL/PE, and BOPP/AL/PE. The treatment effect was compared from the aspect of catechin content. The result showed that the effect of packaging materials of different barrier property is significant on catechin content; the treatment effect order from excellent to poor is BOPP/AL／PE>BOPP/PET/PE>PT/AL/PE>BOPP/PE>LDPE; at the same time, tea need to be stored at normal atmospheric temperature or low temperature, dry, dark, isolated with oxygen to keep catechin relatively stable.
