One-way Degassing Valve Bags / Coffee Bags / Degassing Valve Pouches
Any amount of oxygen absorbed by coffee eventually leads to staleness. However, as the result of sugar browning reactions during roasting, freshly roasted coffee exudes carbon dioxide for up to a week in its whole bean form. For this reason, the highest quality coffees are typically packaged as soon as possible after roasting in a moisture-proof laminated Coffee bag containing a one-way Degassing valve . This Degassing Coffee valve allows the carbon dioxide to escape without “ballooning” or rupturing the bag, but does not allow oxygen to enter.
No Valves
If the coffee is to be packaged using no valves in coffee bags (including fractionally packaged ground coffee), the coffee must rest (“degas”) before it is packaged. It will pick up some oxygen during the degassing process which will limit shelf life, but otherwise the coffee bag will balloon and possibly rupture, exposing the coffee to ambient levels of oxygen.
Packaging material: Coffee is packaged in materials ranging from paper bags to heavy foil laminates and cans. The packaging type also plays a marketing role. In terms of coffee shelf life, the type should be sealed easily (usually by heat) and moisture-proof.
