One-way degassing valves
Specifications
Materials:Β Recyclable PE, paper, and nylon
Frequently asked questions
Specialty coffee roasters use degassing valves for all roast profiles, from light to medium to dark (although darker roasts tend to degas quicker than lighter roasts).
One-way degassing valves are essential when packaging larger volumes of roasted coffee beans, as it will be consumed at a slower pace.
Degassing valves can be fitted so they are visible from the outside or they can be hidden within the packaging layers, without jeopardising the integrity of your coffee bag.
We offer recyclable, BPA-free degassing valves that use a nylon filter valve, which means they are able to retain membrane integrity without cracking, tearing, curling, or breaking.
Recyclable degassing valves can be used to create a user-friendly product for consumers and reduce the negative environmental impact of coffee packaging.
In addition to being versatile, lightweight, and affordable, our valves can be fitted to our entire range of sustainable coffee packaging options.

Preserve your coffee’s quality within the bag.
One-way degassing valves are an essential component for specialty coffee bags. They keep coffee bags airtight by relieving the pressure of escaped gases, particularly carbon dioxide.
These valves achieve this without allowing oxygen to enter the coffee bag, which can jeopardise the integrity of the roasted coffee beans.
One-way degassing valves comprise five pieces: a cap, an elastic disc, a viscous layer, a polyethylene plate, and a paper filter.
A rubber diaphragm is enclosed in a valve and the interior, or coffee-facing part of the diaphragm, has a viscous layer of sealant liquid. This is what helps maintain surface tension against the valve.
Pressure builds up as coffee degasses and releases CO2. Once the pressure inside the roasted coffee bag passes the surface tension, the fluid will displace the diaphragm, allowing the excess CO2 to escape.
