Stick-On Coffee Valve vs Built-In Coffee Valves: Installation, Failure Modes, and Performance
Coffee valves allow roasted coffee to release CO₂ while helping limit unwanted air from entering the package.

How to Match a Coffee Degassing Valve to Flat-Bottom, Side-Gusset, and Pouches
Roasted coffee continues releasing carbon dioxide after roasting. A one-way degassing valve allows this gas to escape while helping limit outside air from entering the package. However, choosing a valve is not only about the valve itself. The coffee spout pouch valve must also work with the pouch structure, fill level, sealing area, and filling…

Spout Cap Anatomy: Spouts, Caps, Threads, Flanges, Bore Sizes, and Compatibility

This is particularly important when comparing a plastic cap spout or specifying cap spout plastic…
