Coffee Pouch Accessories Freshness Coffee Packing Valve For Transparent Bag
Features:
1. When the fermented product release the gas, the one way valve can solved the heat dissipation, anaerobic control, as well as the packaging, storage and transportation, stability ingeniously, greatly reduce the production cost of the fermentation product.
2.One way valve bring coffee bean (solid, large particles) very carefree breathing, avoid outside air into the bag, to prevent pollution by oxidation, effectively guarantee the quality of the coffee, you can smell the coffee fragrance from this valves when you buy the coffee, can better judge the quality of coffee.
3.The bag with a one way valve, when the packing bag handling or high drop, bag of gas can be taken out from this valve, reduce the impact of gas on packaging, avoid broken.

What is advantage of coffee valve?
Coffee degassing valves allow the release of carbon dioxide (CO₂) gas that naturally occurs after coffee beans are roasted. This controlled release prevents the buildup of gas inside the packaging, which can otherwise lead to stale flavors. By maintaining optimal freshness, the valves ensure that consumers enjoy coffee with rich aroma and flavor.By managing the release of CO₂ and preventing the ingress of oxygen, coffee packing valves help extend the shelf life of coffee products. Reduced exposure to oxygen slows down the oxidation process, which is a major factor in coffee deterioration. This results in coffee that stays fresh and flavorful for a longer period.Coffee valves contribute to maintaining the structural integrity of the packaging. They prevent packaging from swelling or bursting due to internal gas pressure, ensuring that the coffee remains securely packaged and visually appealing on store shelves and during transport.
HOW IT WORKS?
When the gas generated by the product sealed in the bag makes the inside of the bag reach to a certain pressure, the gas can be pushed from the inside to the outside to open the one way degassing valve sheet, and the excess gas is discharged outward. When the pressure in the bag reduced to the level which is not enough to open the valve, the valve will close automatically. Meanwhile, the valve will automatically open only when the pressure inside the bag is higher than the pressure outside the bag, otherwise, it will not open, and the air outside will not enter to the bag.
