Shipping a screen?

I'm moving in a few weeks, and am bringing my setup with me. Since I don't have a huge amount of worldly posessions, I'm trying to ship everything either UPS or DHL. Luckily, I have original boxes for all of my gear, except the screen. It's a 100" diagonal, so rolled up the thing is ~85" long.

For people who have done it, what's the best way to package a screen? do they even make boxes/tubes that long? Or will my best bet be to just bubble-wrap the thing and hack a box together from smaller ones?

Thanks.
