Gas-release valves

SEIKO COFFEE developed a valve which allows coffee to be packed right after roasting and maintains the freshness of coffee, based on our innovative technique and long experience as a coffee company.

Structure of Gas-release valve

How to keep the freshness
  1. Even after packaging, roasted coffee breathes ad the packaging will gradually expand. In order to maintain the coffee’s freshness, a safety valve can be attached to the bag and release CO2 off-gassed from the coffee from the package.
    We can also attach the safety valve to the coffee bag. If interested, please contact us.
