When we cleaned out my mother's home in Bay City, we found this big roll of wax paper that was used to wrap all kinds of food, especially sandwiches. It was from Cook Coffee whose salesman came to our house a couple of times a month. The company sold all kinds of items for use around the house.
Then after wax paper came Saran Wrap which was made by Dow about a mile from our house. Then for decades everything was wrapped in that thin layer of plastic. Now it's sandwich bags. What's next?
