Why are Pukka teabags wrapped in individual sachets?

We wrap our organic herbal blends in a sachet because we want to lock in the freshness and protect the high essential oil content which gives our teas such a special taste. Individually wrapped sachets protect the tea bags from light and moisture which degrade the herbs, causing the tea to lose its depth of flavour and herbal health benefits. The sachet also prevents any cross-contamination of flavour or smell with other nearby foods.
