My 46mm rolls also came today, I wonder if it will be safe to freeze one?
As far as the packaging, ILFORD has for years used the paper box with the plastic bag for their bulk film. I suspect the cans disappeared by the 1990 era. Even the old private label stuff was in a box. Basically the same type of package as Paper is supplied in.
The 46mm rolls just have a printed label with the size and the complete address of the maker. And a batch number, no suggested expiry date. I was surprised by the shape of the box, I wonder if they used the same package for the 70mm film? (Stone you have both - care to comment?)
