Milk, Not Plastic, Will Protect Food in the Future
Amrith Ramkumar, Bloomberg 08-21-16
U.S. Department of Agriculture researchers have discovered that a milk protein called casein can be used to develop an edible, biodegradable packaging film. The casein-based film is up to 500 times better than plastic at keeping oxygen away from food because proteins form a tighter network when they polymerize, the researchers found. It’s also more effective than current edible packaging materials made from starch and protects food products that are sensitive to light.

Hmm, maybe they can use the milk that us usually thrown away because it's reached it's sell by date, but is still good.
Also, they'll need to make sure that this new packaging will be OK for lactose intolerant people.
