For those with latex allergies, could balloons be made out of the same material as the non-latex medical gloves?

I am just curious if it's possible to create balloons that are OK for those with latex allergies, but are not the foil or mylar balloon. More specifically it would be nice of the balloon was also clear or nearly clear, free from color. Is such a thing possible? Then such balloons, I would assume, could be distributed to healthcare facilities where latex balloons are banned, right?
