ELI5 Why are silica packets used in product packaging for things like shoes and even bacon bits but not in produce packaging? The packets say they are “non-toxic” and seem like they would help lettuce and spinach containers have a longer shelf life.

Silica packets are made and used to absorb moisture.  So in items like shoes or bacon bits you don’t want moisture there because it might cause mold. Whereas produce like lettuce and spinach are made of moisture. You would end up drying it out very quickly.
