Product Description
One-way degassing valve
Coffee valve
Valve for food and chemical products

-Coffee is a High Quality beverage with delicate flavors. It must be protected from oxygen and moisture quickly after roasting in order to stay fresh for more than a few days.
-Coffee packaging requires a high barrier, low oxygen transmission package with heat seals that are 100% sealed. Multi-Layer film laminations with aluminum foil work well.
-Roasted Coffee also gives off high volumes of CO2 Gas for 1-2 weeks after roasting.
/Question: How do you package coffee in a completely sealed, air-tight bag, yet allow the CO2 gas to escape?
/ANSWER-Use a Functional One-Way Degassing Valve in your package.
-The quality of the package and a one-way degassing valve is measured by its ability to maintain a low amount of oxygen in the bags-less than 5% is desirable, less than 3% is preferred.
- A study done by an independent laboratory found that some degassing valves on the market allow oxygen to penetrate into the bags. They are NOT true one-way degassing valves.
- Compared with those valves stealing the favor of coffee, some degassing valves can not let CO2 released out. This is much worse and would be a potential bomb for the bag manufacturer, coffee supplier and consumers.
- Actually, you can not judge a valve just by looking at it. Some valves may look the same, but not all functions the same. You must test the amount of oxygen in a filled and sealed coffee package in order to test the valve function.
- Jinlong supplies true, consistent ONE-way degassing valves from Pacific Bag, Inc., U. S. Especially for coffee packages and other food & chemical flexible packages.
