One-way degassing valves are also called as freshness valves, aroma valves or coffee valves. They are designed to allow pressure to be released from an airtight package while not allowing external atmosphere (i.e. air with 20.9% O2) to enter the package, which are critical in preserving the coffee from losing its aroma or freshness. These are proved to be the best for degassing of CO2 while not letting the oxygen, moisture or any contaminants to enter in bulk bags or pouches.
Due to COVID-19 pandemic, the global One-Way Degassing Valve market size is estimated to be worth US$ 217 million in 2021 and is forecast to a readjusted size of USD 284.
