Plastic is sometimes useful to preserve fresh food to some degree. Without plastic many goods wouldn’t be viable. Would be nice though if at least the necessary plastic was highly recycleable, as well as cost efficient etc.
There are grocery stores (like Sprouts in my area) that sell fresh food like produce that aren't packed in plastic. They're all loose items that you just pick up and put into your own bag (which hopefully is either plastic that you reuse, or just a cloth bag). Then there are some grocery stores that pack most of their produce like vegetables all in plastic. If no plastic works for one, I don't see how it's necessary for the other.
Go to a butcher and get it in paper. Make your own mayo...it's an egg, veg oil, and a little salt and pepper...store in glass. Salad dressing...store in glass. Metal tops. Pretty much the packaging up until the 70's.
