Yes, white reflects infa-red and ultra-violet as well as light energy in the visible spectra better than black, so would be cooler if you left it in the direct sunlight, etc..
Zip ties seem an excellent idea. If you need local reinforcement of the Coroplast, simply insert a short length of wood dowel of the right thickness into the Coro flutes and tie the Zip around that. (Distributes the load while reinforcing the plastic.)
