Wholesale coffee bags with valve flat bottom with tintie quality

After the coffee is roasted, it will continue to emit carbon dioxide for a period of time. If there is no one-way valve, the coffee packaging bag will be full of gas, which is easy to burst. The one-way air valve can also discharge the oxygen in the coffee packaging bag while discharging the carbon dioxide, so as to prevent the coffee from oxidizing and producing oil and producing peculiar smell.
