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?

Question

Crushing a soda can is easy, crushing a soup can is way harder. The soup cans are also often corrugated. What explains the difference?

Answer 1

Because soup/food cans have to be sterilized, often under pressure to achieve a high temperature (known as retort). The cans will therefore need to be thicker and more robust in order to withstand the extreme temperatures and pressure.

Soda cans on the other can don’t need to be retort grade.
