eli5: Why are soup/food cans so much more robust than beverage cans, even though both cans are made to withstand the pressure of being stacked vertically for shipping and storage?
Crushing a soda can is easy, crushing a soup can is way harder. The soup cans are also often corrugated. What explains the difference?
Edit: thanks for the responses all. The consensus is that can drinks are pressurized, which makes them stronger in general when sealed, so they can get away with using less material. Also, food/soup cans need to be able to withstand high temps since people cook them directly in the can apparently.
