What is the primary scope of this standard?

It covers the requirements and tests for the plywood panels used specifically to assemble traditional tea chests.

Why is adhesive selection critical in tea chest plywood?

The adhesive must resist moisture during long shipping transits and must not impart any volatile odors that could spoil the tea's natural aroma.

How many plies are typically used for tea chest plywood?

Tea chest plywood is traditionally manufactured as a 3-ply board to optimize strength and weight.

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.
