- One-way valves help release excess gas, such as carbon dioxide, from coffee bags. Coffee beans naturally emit CO₂ after packaging, which must be released to prevent the bag from expanding and losing freshness and aroma.
- Also known as freshness valves, coffee valves, or aroma valves, these valves are essential for maintaining coffee quality. They effectively release gas while preventing oxygen, moisture, and contaminants from entering the packaging.
