In my country potatoes are gathered and sold inside sacks
contrary to all other fruits and vegetables that are kept in markets and
in shops in green plastic type boxes. Therefore my question is: Is there
any purpose for potatoes being sealed in potato sacks and not in boxes?
maybe to avoid humidity or tube growing or something like that?
Potatoes are tubers and they tend to sprout. So the sacks limit light
to the potato tubers to prevent sprouting. The sacks provide
ventilation to minimize molding.

The difference between potato and other fruits and vegetables is that
potato tubers are in a state of dormancy. The different storage
conditions likely reflect that difference.
