Coffee packaging knowledge:
After the coffee beans are roasted, if they are packaged in a poor quality coffee bag, the aroma of the coffee will easily evaporate, and it is easily affected by the odor. Therefore, when packaging coffee, it is necessary to avoid the loss of aromatic gas from the packaging bag and the absorption of odor from the outside of the packaging bag. The coffee bag must have certain functions of exhausting and blocking gas.
Packing of one-way valve:
A one-way valve on the bag allows the carbon dioxide to escape but keeps out the outside gas, ensuring that the beans don't oxidize but don't stop the aroma from escaping. The packaging can be stored for up to 6 months. Some coffees are packaged with air vents -- holes in the bag without a check valve -- so that once the carbon dioxide has been drained, outside air can enter the bag and oxidize, thus reducing storage time.
