WIPF Valves

YPAK WIPF valves are quality one-way degassing valves that are designed to preserve the freshness of roasted coffee. Carbon dioxide is naturally emitted by freshly roasted coffee once it is packaged, and unless there is good ventilation, the pressure may accumulate in the bag. WIPF-style valves permit carbon dioxide to pass through the valve but not oxygen, moisture, and contaminants that can damage the aroma, flavor, and quality of the coffee.

These valves are designed to fit in a large variety of coffee packaging styles, including stand-up pouches, flat bottom bags, side gusset bags, and other flexible packaging. YPAK WIPF valves are made of food-grade materials and can be used to ensure reliable performance during storage, transport, and display in retail. Their small size and good airflow make them a reliable option among coffee roasters, packaging manufacturers, and own-label brands that require professional packaging solutions that can increase shelf life and improve product appearance.
