Specimens are stored in low gas-permeability plastic bags with desiccant added to reduce humidity, and may be kept at ambient temperature, even in tropical climates.
On the assembly line, spacers of specific thicknesses are cut and assembled into the required overall width and height dimensions and filled with desiccant.
Storage life for all teas can be extended by using desiccant packets, oxygen-absorbing packets, vacuum sealing or store tea in closed containers in a refrigerator.
