How do protect the coffee from moisture and odor, and keep the aroma of coffee for a long time?  

1, It requires a gadget that exhausts, we call it ‘One side Degassing-valve’, which allows carbon dioxide to escape from the inside of the bag without allowing external oxygen into the sealed bag.

As for grounded coffee/coffee powder, it requires that the valve need to be coated with non-woven fabrics, which can ensure that the powder does not clog the vent. As for coffee beans, then no need for non-woven fabrics.

The different volumes of coffee need a different valve. Coffee bags which under 16oz have required a valve with 5 holes, but if over 16 oz, they need a valve with 7 holes.
