Not a scientist so couldn't quite tell from the article if this would work for its use case; but all of the prepared / cooked food I see at my grocery store is packed in plastic containers. They all have shelf life of that day / maybe a couple of days (this is like a buffet + packed / prepared meals, not sure what exactly to describe it as). I always thought it would be great if that could be less wasteful, it'd definitely make me feel more likely to buy it instead of all being in single use plastic containers.
