How does the packaging barrier work?

Have you ever wondered why biscuits left on the counter turn soft after a few hours? The same process threatens dried medicinal botanicals. Plain kraft paper is porous and lets ambient moisture seep in. That is why our pouches feature a moisture-proof inner lining, a thin barrier layer that completely seals off gas exchange between the inside and the surrounding air.

Quality checks prior to shipping

Every sealed pouch undergoes physical inspections to protect the harvest:

• Seal integrity: We test the heat seal under mechanical pressure to rule out any micro-perforations.
• Residual moisture levels: Mint leaves and blossoms are electronically tested to keep moisture levels below eight percent.

Why this detail matters every day

Dried mint leaves contain menthol, a compound that quickly turns from liquid to vapor. Without a protective lining, menthol leaks through paper pores, turning your tea into a flat infusion without freshness. The inner barrier ensures that the last cup from the pouch tastes as fragrant as the first.
