Ability to use Packed Food/Food Packs as an semi-emergency food source/multi-class food source.
Though using an packed food for trading seems very lucrative as it literally requires a tiny bit of plastic to be lost in exchange for resources - sometimes situation can hardly demand you to put all the food to your settelements instead of food exports factories.
So why not make this situation more flexible by either making "packed food" usable as an some sort of very beefy treat(Feeding a lot more people per unit than other things in "treats" category), or making them apply in several categories simultaneously(based on the "compound" it must be "Carbs", "Protein" and "Treats")?
