Everything is wrapped in plastic, most of it non-recyclable. This is not progress.
I've seen middle grounds where the box itself was made with waxed cardboard (with wrapping). Not sure if this is necessarily better. Only few items I've seen are sold in unwaxed cardboard (and I suppose it depends on the food contained).
I don't know how to calculate which alternative is the least polluting, but it's not obvious at all that lack of wrapping implies less pollution in the big picture.
