What are soup cans made of?

Soup cans are typically made from tinplated steel. Tinplate is a type of steel that has a thin layer of tin applied to it, which helps to prevent the steel from rusting or corroding. The tin layer is also important for ensuring the safety of the food inside the can, as it prevents the food from coming into contact with the steel. Soup cans are also typically lined with a thin layer of plastic, which helps to protect the food from spoilage.
