What is the most popular coffee packaging bags on the market?

1. Flexible non-airtight coffee packaging bag: This is the most economical packaging. Usually, they are used by small local bakeries because they can guarantee a quick supply. Coffee beans can be consumed in time. Coffee beans in this packaging can only be stored for a short period of time. Some people also will use tin-tie to close the bags.

2. One-way exhaust valve coffee packaging bag: After roasting, the coffee is placed in a special one-way exhaust valve. This exhaust valve allows gas to go out, but not in. A separate storage stage is not required, but there is a slight loss of aroma due to the outgassing process avoiding the formation of rancid flavors but does not prevent the loss of aroma.
