I wish I could generate points for the team for complaining about plastic bags for frozen fruits and vegetables, because I would generate an enormous amount of points. I despise them. The bags are small and therefore there are more of them. I don’t have an answer, but I think back to childhood for options before plastic. As I recall from earlier years frozen food was in waxed cardboard.
Or, Literally farm to table setup- just a box of produce with the dirt still on.
Wooden crates were also used in the past for fruit. I still have a very thick waxed cardboard box from the eighties sporting “Melons”.
