there are a few good semi psychological tips which can be used at hardly any cost. noting "do not top load " will help. Labeling "fragile glass" will make a difference. "tip N Tells" are stickers with a plastic triangle filled with sand which shows if the cartons are tipped. from my experience, they do help quite a bit. a guy flying around on a towmotor will notice them as they are eye catchers. subliminal caution.
doing something visually to make the carton stand out helps.the only downside of banding it to a pallet, is as it is usually handled by forklift theres a blade pierce chance as well as a good chance of freight being stacked on top as it will usually be loaded on the bed of the truck.
but i would still go with banding it to a pallet. its a crap shoot any way you look at it, but you may as well do your best to swing the odds in your favor.
man that was a nice looking reel to reel.
