Coffee bag one-way exhaust valve use: one-way exhaust valve encapsulated in the coffee bag, while sealing the one-way valve position by punching holes on the surface of the bag, so that the carbon dioxide precipitated from the roasted coffee beans can be automatically discharged from the bag under a certain pressure; one-way exhaust valve with a filter, blocking the influence of the powder on the exhaust valve so that the gas inside the bag is discharged while preventing the solids (including dust) inside the package from flowing out to ensure that the outside world. Air cannot enter the bag. Effectively ensure the dry and mellow flavor of coffee beans or coffee powder, will not cause the bag to open due to the accumulation of carbon dioxide, and prevent the inner packaging from oxidation and deterioration.
