I've never tested one to destruction (must get round to it one day) but I know you can drop them 6 foot onto concrete and nothing will happen. The biggest problem is cosmetic - put anything opn top of them for too long and you can get an imprint in the styrofoam which shows through the canvas.
Maybe I was unlucky, but I posted a violin, that I'd sold on ebay, in a styrofoam case and when it arrived there was a huge split (not just a crack) in the belly of the instrument.... and it was posted with the bridge and the soundpost down!
I know that courier companies have drivers who are not always the most careful of handlers of the goods (even when labelled FRAGILE - handle with care), but the damage to the violin was horrendous. I can only imagine the package had been thrown onto the floor of the van and gradually, over the day, more and more parcels had been dumped on top. The styrofoam lid of the case, unlike domed laminated wood, had gradually been crushed downwards onto the belly of the instument.
Musafia probably have one of the most rigorous testing regimes for violin cases. They test impact destructability by driving down the road having left the case, with a violin inside, on the top of the car. The case eventually leaves the roof when the car reaches 30+ mph. They also leave cases out on rooves of buildings, in various climates, to see what happens to the case frames, outer materials and lining. The lids of Musafia cases are also able to withstand a weight of 130 kg placed on top of it. And if that's still not enough to convince anyone this is the only case they will ever need to buy, they come with a lifetime guarantee!!!!
It often pays to go the extra mile in the first place.
