Four types of packaging for coffee bags

- Mar 27, 2019-

1. Flexible non-hermetic packaging: This is the most economical package. Usually used by local small bakeries because they guarantee a fast delivery. Coffee beans can be consumed in time. Coffee beans in this packaging method can only be stored for a short time.

2, airtight packaging: After loading the coffee, vacuum and seal it. Due to the formation of carbon dioxide during the baking process, the package can only be packaged after the coffee has been allowed to degas for a period of time, so there are several days of storage. Coffee beans are placed longer than coffee powder. The cost is low because it does not need to be separated from the air during storage. The coffee in this packaging method should be used up within 10 weeks.

3. One-way exhaust valve packaging: After baking, the coffee is placed in a special one-way exhaust valve. This vent valve allows the gas to go out but cannot come in. There is no need for a separate storage stage, but there is a slight loss of scent due to the deflation process. It avoids the formation of a corrupt taste, but does not prevent the loss of aroma.

4, pressurized packaging: This is the most expensive way, but can save coffee for two years. After a few minutes of baking, the coffee can be vacuum packed. After adding some inert gas, maintain proper pressure in the package. The coffee beans are stored under pressure to allow the scent to flow over the fat, thereby improving the aroma of the beverage.
