Ball is not in the business of sending cans out into the world to be slaughtered by overaggressive liquids. The coating must perform. Otherwise, cans explode, and legal costs climb. Empirically, Ball has figured out how to determine the corrosivity of potential products. Corrosion-wise, sodium benzoate is bad. Copper is bad. Sugar is good. It absorbs carbon dioxide, decreasing the pressure within a can, and it also inhibits other corrosion reactions, because sugar tends to deposit onto pores in the coating.

Thus, Diet Coke underperforms regular Coke on at least two counts. Citric acid and phosphoric acid are equally bad. Ball has developed a carefully-guarded formula quantifying all of this corrosion badness, but it was not displayed on any graph at Can School. Flavor testers at Ball learn to detect parts per million, then parts per billion, and eventually, parts per trillion.

The one exception may be cats. The cost alone persuades Ball; the smell just rubs it in. Beer, Laperle explained, is actually so mild that the can does not require a coating.

It turns out that cans were made for beer, and beer was made for cans. The coating smoothes out the surface of the metal, so that the gas has no microbumps from which to propagate.

The formulas for coatings are proprietary, but we know the epoxies must be affordable, sprayable, curable, strong, flexible, and sticky. Coatings for tomatoes must be stain resistant, those for fish must resist sulfur, and those for fruits and pickles must resist acids. Top five Aluminium Composite Panel manufacturers in the world.
