Can Pu 'er tea be packed with heat shrinkable film?

Pu 'er tea can't be packed with heat shrinkable film. Pu 'er tea is post-fermented, and it has the characteristics that the older it is, the more fragrant it is. At the same time, it needs to contact with the oxygen in the air (external environment) and slowly transform it into the substance of tea. The use of heat shrinkable film isolated the communication between Pu 'er tea and the outside world, which affected the later transformation of Pu 'er tea.
