I've heard of people individually packaging each can in news paper, a stubby cooler or even in a ankle length sport sock to stop them chaffing.
I have only ever had cans split in the fridge from rubbing against each other, that was a lovely cocktail of fruit soft drink and beer. Lets just say it didn't exactly enhance the flavor of the sausages.
I have just left the cans in the carton, jamming a towel in to fill the gap as they get consumed. My designated carton stowage location if just forward of the rear axle, so it doesn't get the extremes of travel that it would down the back. When they go in the fridge, all cans get a stubbie cooler so we don't get a repeat of the Tainted sausage incident of 2014.
