I'm really trying to think, but I don't think I've encountered styrofoam in years. All the packaging for mid-sized consumer products that would have used it in the past (small blender, air purifier, dust buster, etc.) seem to use either formed cardboard or else folded cardboard with cutouts.

The last times I remember seeing it were when I bought a window AC unit and a portable digital piano. Both of which weigh 25+ pounds, where I think only styrofoam is the only economical material which exists that is both protective enough but also able to support all that weight. I'd guess heavy blenders would also still need it.

So not sure we need to ban it if manufacturers have already mostly stopped using where cardboard is a viable replacement? Unless there are categories of products still using it that I'm missing?

Same with styrofoam for to-go food containers -- everything I see is plastic or cardboard now, haven't seen styrofoam in years. Unless this is regional?
