RJ Pack is a professional supplier of Stand Up Coffee Pouches in China. Stand Up Coffee Pouches With Valve are used for packaging roasted coffee and ground coffee. When coffee beans are roasted, they tend to continue to release carbon dioxide gas for more than seven days. In this case, a one-way degassing valve is installed on the coffee package to allow the gas to escape. Excess carbon dioxide can cause your coffee bag to break, exposing your coffee to harmful oxygen, moisture, odors and ultraviolet light.
