In the big, big grocery store I use, there isn't much choice about plastic. Over (I estimate) 80% of the products (outside of fresh fruits & veggies) either are containerized in plastic, or is boxed or canned food which is wrapped-in plastic (e.g. cereal) and covered with or wrapped-in plastic. We need to see a big turnaround in this situation.
I don't see much recognition - from manufacturers or consumers - of how many tens of tons of tossed-away plastic are carried out of most of these stores every day. Consumers have few alternatives ... no sign that food packagers give a damn ... or that stores (most are corporate-owned) are struggling to make wiser choices.
It's a lot bigger problem than what container we use to carry our purchase to the car.
My dystopian expectation is we'll probably settle on all plastic should be white so it can reflect light back into space, replacing albedo effect we got from all the snow we used to have
