With the notable exception of Pringles, most potato chips come in plastic bags.
To avoid having the chips crushed during shipment, manufacturers use a
simple technique: they slightly pressurize the bag of chips as they seal
it, which adds significant strength the the bag, and protection from
crushing for the chips. Of course "some settling of contents will
result from shipping and handling."
So when I punctured a blister pack of electronic accessories recently, I was
amused when a rush of air escaped... the blister pack was pressurized! Have
the electronic manufacturers rediscovered the same technique for strength of
packaging for their electronic chips?
