Roasted Coffee generates Co2 gas up to 7 days. To degas and protect aroma of coffee in the same time, you may need to use bags with valve applied in advance. We provide this valve application service. We have two automatic valve applicators as shown below and our workers to apply valves for you. You can send us your valves and coffee bags for pure valve application service or you can also use valves that we already have here.
As said, Misung Pack also specializes in valve researching, designing and production. We have been making every effort to produce wonderful working valves. Our Fresh Coffee Always_ Valve SPV01 (w/o filter), SPVF02 (w/ filter) have compatibility with other well-known valves, works as excellent as other valves do.
