As the names says, Coffee Valve pouches are exclusively used for Coffee Packaging. These pouches are fixed with a De-gassing valve which acts as the major catalyst in the use and packaging of these pouches. The Degassing valve allows excess Gas/CO2, which coffee still produces for some time after roasting, to escape, while at the same time oxygen cannot enter the coffee pouch. Hence, the Predominant features of the De-gassing valve is that it secures the Aroma, Flavor & Freshness of the Coffee excellently. The coffee valve pouches usually have Aluminium as the Sandwich layer which is always preferred and works best for Extended Shelf-life, Moisture and Barrier strength.
