In this blog post on Rheo Thing, John explains that he is the "guy that everyone hates. The guy who made it so difficult to open your bag of potato chips."

It was my first job right out of school. I was working for Hercules Chemical, a company that no longer exists although you have to blame that on some one else. I was in the Packaging Films Group, making multilayer polypropylene films for food packaging. The film had a heat-seal adhesive on one side of the polypropylene base. One of our larger clients used our films to make potato chip bags. The problem they had with our existing films was that the they seal was too weak. The client's chip-making plants were located west of the Rocky Mountains, so when trucks would drive their chips out to California, some of the seals would open up due to the pressure difference between the high altitude air and the air sealed inside the bag. And so they needed a stronger seal from us, which was then passed down to me.
