I have no idea what it would take to stop that and what the substitute would be. Examples: I like Japanese Milk Bread. It generally comes wrapped in a plastic bag, arguably because it's not hardy like something like sourdough which can be sold in an open paper bag.
Similarly, local markets sell Chinese sticky lotus leaf rice, 2 or 3 in a plastic container, they sell fresh tofu skin in a plastic container. I guess they could try to switch to waxed cardboard like milk is sometimes sold? Is that good or is that cardboard infused with plastic?
Has any "progressive" country banned plastic such that pre-sliced meat/cheese is not sold in plastic?
