Well, as an insulator cardboard, like any insulator, is capable of storing static electricity, but as there are no ESD sensitive devices in that Strat, does it matter? If you were really concerned about ESD in this scenario, all I'd suggest is touching a grounded point before touching a component in the guitar. If the guitar is plugged into an amp, then thats anything metal on the guitar.
