Multigrade Paper

Multigrade Paper
How long is the last photo paper?

I bought a packet number Ilford Multigrade IV paper in 2004 for a course that was in that time. Some have opened, but stored in the refrigerator. Others remain Unopar and have been stored in the attic. Just stumbled on them recently. Does the paper have an expiration date because it does not seem to find any indication on the exterior packaging. Thank you.

Keep in a cool and dark as his loft (Unless it's very hot in summer) of paper and photographic films, especially unpacked last almost indefinitely. If you still printing B / W you can check very easily by the same negative impression on a sheet of old paper and a sheet of paper.
