How to use coffee bags correctly

I found that after many friends and guests got the coffee, they asked me if they sold "golden hoop sticks" or self-sealing bags. Our coffee uses a combination of one-way valve and sealing strip (tin tie). This combination is actually very convenient, and there is no need for additional sealing aids. It is just that many friends do not use the sealing strip properly, or think it will be useless after it is opened, so it is torn off. Now let me briefly explain to you how to use coffee bags and seals correctly.

Coffee beans are most afraid of moisture and oxygen after roasting, and this seal can effectively release air after each use, preventing the air from repeatedly entering the coffee bag and speeding up the coffee oxidation process.
