Our signature loose-leaf tea packaging with a zipper pouch and vacuum-sealed pack serves a specific purpose. The vacuum seal helps to remove any air from the package, creating a sealed environment that minimizes exposure to oxygen or moisture. It also helps to preserve the flavor, aroma, and overall quality of the tea leaves for a longer period. The zipper pouch allows you to transfer loose-leaf tea once the vacuum seal is broken and to reseal the tea after each use. This helps to prevent air and moisture from entering the package when the tea leaves are not in use, further preserving their freshness and preventing staleness. In combination, it creates an effective barrier against external elements that can degrade the quality of loose-leaf tea.
