Slop.

Why do people assume that just because we aren't doing branding the packages need to be plain? You could have artwork on them, and color code them so you know what's what easily. Like green for snack items and have the packing be various green paletted artworks You could put PSAs on them too. Or healthy recipes that use the items to give people ideas for what to do with them. Not in the "buy our brand of shit to make this random recipe we made using all our products" way, but just like actual healthy recipes that are simple and cheap to make.

The packaging of products has so much potential if it wasn't being wasted on branding. You could do kids items that have both cute animals and fun facts. Like stuff they need to know for school.

Portion suggestons would be nice too. Instead of just a nutrition facts panel on a box of cookies you could literally say like "3 per day max is best" to remind people not to eat too many snack foods. You could even print the full recipe of pre-made items on the package and encourage people to try making it themselves sometimes. To reduce the need for mass produced products.
