Ever wondered if your potato chips bag was really sealed and well protected against external contamination ? Well, there's certainly lot of different ways of testing it for sure. But here's one you might not have think about.
Chips bags are sealed mostly on low altitude facilities. Guess what happens when you climb up a place like in the French Alps at Saint Véran at 2930m (9613 feet)?
Pressure inside the bag is higher than outdoors. The bag expands because it is well sealed.
If not? Well ... better think again before eating them.
!! Test Passed !! Bon appétit
