I work in a factory which has low humidity rooms (for manufacturing medical products) and I have also visited Ilford's factory.

I might be wrong but I would say that as far as Ilford is concerned, their films are packed in a normal humidity environment. Not sure about other manufacturers but I would be surprised if they packed in a low humidity room.
