Kodak paper expiry

[Alpacaman]

I recently brought some darkroom equipment, and it came with a few opened packets of Kodak paper. I have no idea how old it is, it looks fairly new, I would give it 10-5 years (I do not know how long this stuff has been out of production). Anyway, does anyone know if these things expire? After how long?

Edit: I just remembered - I checked the packets for an expiry date, and I didn't see any.
