I would not be surprised if to make some sizes, they actually start with a larger size, and then have to cut it down by hand, throwing away the trimmings. Also they may have to make the box by hand, and or cut a filler piece for a larger box so that it is packed securely.

If they had to make a tool to cut the film, your cost includes part of the cost of that tool.
