Assuming these are electrical cables, they are conductive so static can't build up on them. It is possible for static to build up between different cables and break down their insulation but the chances are one in a billion it would happen. A normal plastic bag should be adequate.
If it's a coaxial or multi-conductor cable then you might
(if you're quite paranoid) worry about dielectric rupture
and consequent leakage.
What is the short-term insulation breakdown rating,
and what is your believed ESD threat voltage? And, how
would that voltage be imposed once the bad is closed?
Not only that but your threat presentor would have to
apply voltage between core and shield (or between two
specific conductors, which means accessing the bare
ends, quite unlikely in a bag of coiled cable and even
less so when rolled on a spool and the ends tucked in).
I would say "forget about it" but you may feel better
if you put some numbers to it.
On the other hand I'd expect that antistatic bags have
price compressed to near "plain old" in this day and age,
and maybe you put your logo on one and call it a
branding / marketing expense. You know, "show 'em
you care" (even if it's something that you should not
I have never once seen an "ESD sensitive" symbol on
any wire product, and I've bought a not-insignificant
amount; single, multi-conductor, coax.
