To counteract the tendency of film wound in a supply compartment from clockspringing and resisting initial unwinding, at least the outermost film convolution on the supply roll is transversely corrugated. As the film ages in the magazine, its inherent plasticity causes its clockspringing tendency to diminish and its corrugations to relax, thereby reducing the frictional contact pressure between the outermost film convolution and the compartment walls.
