Gerry,
These days the new rolls come in black plastic bags folded over, and stored in boxes that are almost light-tighta box or tin with a lid (whereas many sheet-film boxes are three piece, still shipped with the opaque bagsome are two piece with the opaque bag).
I have some extra tins, boxes, and bags, and would send a set on to you for postage.
When I store these in the fridge or freezer I also seal them in a zipper plastic bag, mainly so that when I thaw them they do not produce much condensation inside.
