Nearly every food item on the shelf has plastic. Aluminum cans are lined with plastic on the inside, glass bottles have a plastic freshness seal/cap. Even pasta boxes, one of the few cardboard packaged goods that don't have an inner plastic liner often have a little plastic window so you can see what the pasta looks like.

And yet we're being told that plastic bags are the problem. Literally the only plastic thing you get from the grocery store that isn't single use. Instead we have paper bags which are bulkier and have a higher carbon footprint, and we still end up with a bunch of actually single use plastic bags because we no longer have anything to use as small garbage bags.
