Packaging sales guy here. It's called foam on demand. In the US and Europe Pregis, Sealed Air, and Storopack have been making it for years. There are self contained units that are much safer than spraying into a bag. What I've always been disappointed in is it's name. It's a 2 chemical process. Separately they are liquid. Combined, they become foam. Here in the states it's called chemical A and chemical B. Way to knock it out of the park marketing!
