Sorry I don't know what "banana boxes" are.
We use rectanguar plastic boxes with flat lids so they stack when required. The boxes we use are about 25 litres and do come in larger and smaller sizes.
The good points about the boxes is they are cheap to buy, you can see what is inside, if something spills it is contained, other things in the truck do not leak into the box, at a pinch can be left out in the rain in an emergency, seem to have quite a reasonable service life of say 5 years at least, but can split or crack if dealt a blow. They are susceptable to discolouration if left in the sun.
