I think if you use "real" plywood, you should be fine. By "real" I mean
that you should avoid particle board and the varieties of pressed wood
known as "chipboard". All of the pressed wood varieties use formaldehyde
in the manufacturing process which is known for out-gassing. Genuine
plywood that is made from thin (veneer like) layers is also stronger
than pressed wood. I would go so far as to use exterior grade plywood if
the additional cost is not prohibitive because it will survive moisture
(even getting wet) much better than interior grade.
Since you are in an active earthquake zone, you might consider packing
the disks as though they are going to be shipped.
