Many years ago all canned food including soda and beer came in tin cans Later soda and beer converted to aluminum cans but today soup and all canned fruits or vegetables still come in tin cansWhy don't they use one metal (either tin or aluminum) for all cans?I think I know the answer but I want to see if others come up with the same reason.
There are 2 main reasons for beer and soda packaged in aluminum rather than tin cans1tin can spoil the quality of these beverages2Aluminum cans can be manufactured with less seams, thus supporting the carbonation pressure better.
