Custom Coffee Bags with Degassing Valve: The Complete Guide
Why Coffee Bags Need Degassing Valves
Freshly roasted coffee beans release CO2 gas for 48–72 hours after roasting. Without a degassing valve, this gas buildup causes bags to bloat, burst, or force stale air into the bag when pressure equalizes. A one-way degassing valve solves this by letting CO2 escape while blocking oxygen from entering — keeping beans fresh for 6–12 months.
The valve is a small, round disc (typically 15–25mm diameter) heat-sealed to the bag surface. It contains a silicone membrane that opens under internal pressure and closes when external pressure pushes against it. Custom coffee bags with degassing valves are the industry standard for specialty and third-wave coffee brands.
