No, it's a simple white box, much like the polywarmtone I've used recently. It just says Forte black and white photo paper on the box. The lable just says glossy, coldtone, fibrebased, multicontrast. The polygrade I've seen actually says polygrade on the lable.
This may just be older or newer iterations of labels than I'm familiar with, I'll trust that it is likely to be polygrade in the box.
