How the little degassing valve helps a lot to protect your coffee aroma?
Degassing valves are crucial components in coffee packaging, especially for freshly roasted coffee beans. When coffee is roasted, it releases carbon dioxide (CO2) gas for several days afterward, a process known as degassing. If this gas isn’t allowed to escape from the packaging, it can cause the package to swell or even burst.
Degassing valves work by allowing the release of CO2 gas from the coffee packaging while preventing air from entering. They typically consist of a one-way valve that allows gas to escape but prevents air from entering the package. This valve is designed to open when the internal pressure exceeds a certain threshold, allowing the built-up gas to escape, and then reseal once the pressure decreases.
Originally developed for coffee, pet food and now utilized widely by other markets, KenHigh’s signature one-way degassing valve allows carbon dioxide to escape from a package without allowing oxygen or moisture in. This cleverly engineered 5-piece valve, about the size of a button, brings with it a host of benefits that include:
- Longer product shelf life
- Preservation of product quality, taste and freshness
- Compact, stable palletization for storage and transportation savings and ease
- Opening and closing pressures that ensure consistent, leak-proof operation without package over-inflation
- Durable design built not to bend, crack or flex under normal use and to withstand thousands of openings and closings
- Unique valve caps that are mechanically locked into bases to protect internal valve parts from damage and prevent debris from entering the valve
- Facilitation of steam release during microwaving
Flexible packaging machines of KenHigh can be customized so that one-way degassing valves are seamlessly integrated with both 3- and 4-ply laminates. Consider adding these valves to your packaging system for any food, industrial or agricultural product where gas release is an issue.
