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.
