Soda cans have lots of plastic in them.
What? Soda Cans are made of aluminum, aren’t they?
They have a plastic lining to stop the soda from tasting like metal.
They need a liner on the inside mostly epoxy or polymer.
Ah I thought only paper products needed an inner coating like that. Is there a concern of it oxidizing or something?
Aluminum is poisonous in larger amounts and a lot of can contents are pretty acidic. You could probably line them with non reactive metals like gold, but thst would be very expensive in comparison.
Bummer. I guess glass it is then.
Glass because the added weight ends up being less eco-friendly than plastics during transport. So it's better to only get glass from local distributers. Also the recycling process of glass is fairly eco unfriendly too.
Aluminum cans might be the best we have for now. I have seen paper milk carton style containers come up more often. As well as plant based plastics.
