Choose high-density, high-pressure, thick, strong and tasteless food packaging bags. Tea leaves can be wrapped in soft and clean paper in advance and then sealed in food bags. 2. Tea thermos. You can use a waste hot water bottle with poor thermal insulation, fill it with dry green tea, cover it with a cork and seal it with wax. Then put it in the freezer or freezer of the refrigerator.
