The plastic wrap that many food items are sold in at the grocery store is not as great as you think. According to Bloomberg, this plastic is hard to recycle, and even adds harmful chemicals to your food. But this could all change in a matter of three short years.
The U.S. Department of Agriculture has been experimenting with a new edible, biodegradable packaging wrapper. The packaging is made out of casein, which is a milk protein. Due to the tighter network of proteins, casein is roughly 500 times better than plastic at keeping oxygen away from food.
