Kodak has been "completing" that transition for several years now and Perez is still leading the whole mess! Yeah, Kodak was up sharply yesterday. It was pitiful all the same.
Now, on cans. Ever put an air tight plastic bag of something in a freezer? Note the creeping ice? Film is filled with volatiles that can slowly outgas and creep through the weak seals of the plastic containers which might withstand an abrupt change in pressure but which might not withstand a slow change in environment.
I am not saying it WILL, I am cautioning you that it MIGHT be bad, or at least not as good as hermetically sealed foil wrappers or metal cans which were used 20 - 30 years ago. The storage conditions have changed because of the packing material.
