The reason that cranberry sauce labels are upside down is that it makes the cranberry sauce easier to come out of the can.
The rounded edge of the cranberry sauce is at the top, and the sharp, can like edge is at the bottom because the rounded end of the cranberry sauce can is filled with an air bubble vacuum, which makes it easier to get the sauce out.
If the cranberry sauce was put in the can the other way around or you opened the can of cranberry sauce the other way around like a normal can of food would be opened then it would be harder to get the cranberry sauce out.
I used to think that the label was accidentally put on the can upside down but I found out later that the cans of cranberry sauce are purposely put upside down with the label a different direction for easier removal of the cranberry sauce.
