Plastic tubs are not airtight, and the stuff in them will have mold spores on them as a matter of course - there are small concentrations of mold spores in the air all the time, so put goods in an environment where mold grows (over about 50-55% humidity usually) is an invitation to mold / mildew in them - particularly on fabrics and paper items (including cardboard and photos), not to mention rusting/corroding metals.
Worse - taking tubs of goods from the presumably warmer upstairs part of the house to the presumably cooler basement will also increase the humidity even in sealed containers - because as the container cools, the air can hold less moisture, so the humidity goes up - sometimes till it forms actual condensation on the container. (The reason a cold drink glass "sweats" on the outside - as the moist air his the cold surface the amount of moisture the air can "hold" as water vapor drops, sothe moisture drops out on the containear sides. The same thing can happen if an upstairs containear is moved to a quite cool basement (especially if upstairs is warm and humid like in normal summer conditions) - causing condensation in fabrics and even on the inside of the tubs themselves. Even "vacuum sealed" bags, with most of the air evacuated, can have this problem. Basically, if they are outside of the "conditioned" space (heated/air conditioned) so signfiicantly different temperature and/or humidity, attics and basements and crawlspaces are lousy places to store anything but maybe pieces of plastic pipe or such which moisture does not affect. Also - if you have mold in the basement, not a good thing - because the spores will float in the air into your living space - see the Home > Mold and Home > Basement Waterproofing link under Browse Projects, at lower left, for more on that.
