I found out why during a recent IoPP tour of the Mocon Ametek facility in Brooklyn Park. The reason is that potatoes will go rancid if air gets into the bag, so they fill the bag full of nitrogen. This process also helps the product stay intact during shipping.
Mocon does packaging testing for the food & beverage, medical device, pharmaceutical and flexible electronics industries. They ensure that whatever is inside the package will maintain its integrity. This is very important in today's packaging market. We also heard from Dr. Keith Vorst, Director for the Polymer and Food Protection Consortium at Iowa State University. He talked about how pre-made food packaging is not going away any time soon. It is a huge market that many big retailers are getting into.
During this talk, I learned that it is more important than ever for the designer to work with packaging specialists from the beginning to help come up with a solution that is attainable with current technologies. If you have a product that needs specialized packaging, I would love to help out!
