Coffee bags are designed to preserve the freshness, aroma, and flavor of coffee beans or ground coffee. Typically made from materials such as kraft paper, foil, or multi-layer plastic films, coffee bags provide a strong barrier to moisture, light, and air, which are key factors in preserving the quality of coffee. These bags often feature a one-way degassing valve to allow gases from freshly roasted coffee to escape without letting air in, preventing the coffee from becoming stale. Coffee bags may also come with resealable closures for easy use and to maintain freshness over multiple uses. The size and design of the bags can vary depending on the type of coffee and brand, with some offering luxury or premium packaging for higher-end coffee products. The trend toward sustainability has led to an increase in the use of eco-friendly coffee bags, including recyclable, biodegradable, or compostable materials.
