For the products which is related to the coffee, it could be divided into different products, such as the coffee powder and the coffee bean.
The type of the packaging for coffee bags:
- Flexiblepackaging without Air Valve:
This is the most economical packaging. It is usually adopted by local small baking plants because they can guarantee rapid supply. Coffee beans can be consumed in time. Coffee beans in this packaging can only be stored in a short time.
- Packagingwith Air Valve:
After the coffee is packed, it is vacuum and sealed. Because carbon dioxide is formed during the baking process, this packaging can only be packed after the coffee is placed for a period of time, so it has a storage interval for a few days. Coffee beans are placed longer than coffee powder. Because it does not need to be separated from air during storage, the cost is low. The coffee under this packaging should be used up within 10 weeks.
- One -wayair valve packaging:
Coffee is placed in a special -directional air valve packaging after roasting. This air valve allows gas to get out, but cannot come in. There is no need to store the storage stage, but due to the air -deficiency process, the aroma will have a little loss. It avoids the formation of corruption, but it cannot prevent the loss of aroma.
- Press packaging:
This is the most expensive way, but it can save coffee for two years. After a few minutes of roasting, coffee can be packaged by vacuum. After adding some inert gas, keep the packaging in a certain pressure. Coffee beans are stored under pressure to make the aroma flow on fat, which improves the aroma of the coffee.

The Type of Air Valve
Though the products are the same, it is related to the coffee. For the different product of coffee, the air valve is different.
The air vale for coffee powder need to be with filter screen, it could better protect the powder. Foe coffee, the normal air valve is necessary.
Why do we add the air valve on the coffee packaging:
The principle of one -way air valve is: when the gas is generated in the bag, it can bring up a certain pressure in the bag, the gas can be pushed away from the inside out, and the excess gas can be discharged; When the valve sheet, the valve is automatically closed. And only when the pressure inside the bag is higher than the outside pressure, the valve will be opened automatically. On the contrary, it will not be turned on. The air and water steam outside cannot enter the bag.
6 major advantages of one -way air valve:
1) Smell the fragrance. The scent of coffee is heard through the air valve, so as to determine the quality of coffee
2) Prevent baggage. The roasted coffee beans discharge their excess carbon dioxide out of their bags to prevent rising bags.
3) Frequent flavor. Avoid coffee beans from volatilization due to oxidation, making coffee fresh.
4) Conservation of oxidation. It can block the oxygen and moisture outside the bag into the bag to avoid oxidation of coffee beans.
5) Good materials. Our coffee bags use high -quality imported raw materials to ensure that it will not pollute products.
6) Anti -rushing pressure. If the bag transports and falls at high altitude, the air valve can reduce the stamping of the air generated in the bag and avoid breaking the bag.
