Yes, a RETF serves nicely for food packaging, especially in the retail space. Here's an example of a cheese product that is well presented in a RETF box at a fresh produce and grocery store. The nice thing about it is that you can also use them in a refrigerator without the need to re-package the cheese or the food product inside in a different container if you don't consume the entire portion. So it's great for reuse after opening within the same package as well as displaying neatly in a store (as the square shape allows it to stack nicely).
