How It Works


Freshly roasted coffee beans release large amounts of CO₂ after packing.
  1. Internal CO₂ accumulates inside the coffee bag and raises pressure.
  2. The internal pressure pushes open the silicone diaphragm of the valve, gas flows out.
  3. When internal pressure drops, the silicone membrane resets and seals tightly.
  4. External oxygen & moisture cannot flow back into the bag, locking coffee aroma.
