It's paper! Not sure what exactly to say about it but it has a good brightness level feels pleasant enough and seems to be working in our printer. As for packaging the cables that cinch the box shut were a bit too tight to be used to carry the box. As the box was delivered to an incorrect location in the building I had to carry it back to our office and it would have been easier to do if the cables had been a tiny bit looser. The box was sturdy enough not to be crimped or cut by the cables which I appreciated.
