Practical Notes
Moisture content must be strictly controlled to prevent fungal growth and tainting of the tea.
Adhesives used should be moisture-resistant and completely free from any foul odor that could be absorbed by the tea leaves.
The use of plywood tea chests has significantly declined in favor of multi-wall paper sacks and corrugated fiberboard boxes.
