Kevlar reportedly retains its properties at cryogenic temperatures.
Perhaps a nylon balloon with kevlar fiber
reinforcement would do.
It also looks like polyethylene (PE), a favored high altitude balloon
material, is used in shatterproof dewar flasks. (And I do recall trying
to shatter a PE funnel on a tile floor after using the funnel to fill a
flask with several gallons of liquid nitrogen. No luck, though it
bounced pretty high.) One maker of the material claims PE works well at
cryogenic temperatures.
