  • There’s also a reason for that too. The bag not only needs to be inflated with air to protect the chips, but it also has to have plenty of room for that air to expand and contract due to atmospheric pressure changes. For example, if you made the bag just big enough for the chips and enough air that when pushed or squished a bit it doesn’t cave in on the chips. And your manufacturing plant is at sea level. When those chip bags go on a truck and arrive at 8,000 feet in Colorado. All the bags would be popped because the air inside expanded far beyond the left over capacity of the bag, so POP!
