That sounds about right to me. Remember, the general meaning of pink and
black (at least back when I was actually an engineer) was that black plastic
bags, foam, etc indicated "static dissipating" ... the material was actually
slightly conductive. Anything pink in color was defined as "non-static" ...
meaning that the material would not contribute electrons or ions to the
environment that would cause static voltage buildup. Pink material was
usually non-conductive but was allowed in static sensitive environments.

I believe the silvered ones do work like mats.
As people seem to be under the impression that metalised bags are highly
conductive, I measured one, and it comes out to be about 4 MOhm/square,
which is not very conductive by my standards. In fact, within the
measurement tolerances, my anti-static mat has the same surface
resistivity!
I may be wrong about the pink ones though. They had about 4 times the
resistivity, but still on scale.
