The secret for freshness preservation.Have you ever noticed that there is always a plastic sheet with a small circular hole on the coffee bag? This inconspicuous small device is the key to coffee preservation - the one-way degassing valve.
After roasting, coffee beans will continue to release carbon dioxide. Without a one-way degassing valve, the coffee bag will expand like a balloon and may even burst. The cleverness of the one-way degassing valve lies in its ability to only allow gas to be discharged in one direction, without allowing outside air to enter, perfectly solving the problem of packaging expansion.
This small device with a diameter of 20mm has a very precise internal structure. It is precisely this exquisite design that allows coffee to be preserved in its optimal state.
The one-way degassing valve is not only a functional component, but also an indicator of coffee freshness. When you gently squeeze the coffee bag and smell the aroma overflowing from the air valve, you can feel the freshness of the coffee. This intuitive experience makes one-way degassing valves an indispensable part of coffee packaging.
From professional coffee shops to supermarket shelves, one-way degassing valves silently guard the quality of every cup of coffee. This small invention embodies the wisdom of food packaging design and allows us to enjoy fresh and delicious coffee anytime, anywhere.
