Fuji instax film - can you freeze it?

Hello,

I find polaroids (or their modern equivalent) make excellent gifts in the remote parts of the world, but I'm off to Nepal this January, and it gets very cold there. Fuji give an operating temperature range of 5C - 40C which is OK - I'll mainly be using it during the day. But nights will regularly be -10C, sometimes much colder. The film will end up getting frozen (and thawed) on a regular basis. Will it survive that kind of treatment for 3 weeks or so?

Since the camera and film are quite heavy, I don't want to take it if the film will just get ruined on the first cold night. Does anyone know, before I start experiments with my ice-box at home?
