What is the common coffee packaging bags in the market?
There have two types of coffee packaging bags commonly found on the market:
- Flexible non-airtight packaging: This is the most economical packaging. Usually 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.
- One-wayย exhaustย valveย packaging: 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. It avoids the formation of rancid flavors but does not prevent the loss of aroma.
