Aluminum cans are lined with plastic.
This plastic lining is primarily used to prevent the beverage from reacting with the metal and to protect the can from corrosion, as acidic drinks like soda could damage the aluminum over time. The lining also helps preserve the taste of the beverage by preventing it from absorbing a metallic taste.

When you consume a beverage from an aluminum can, you are consuming 100 times more plastic, than aluminum.
