We bought some plastic storage boxes that were coated
with a blue anti-static film.  They told us it passed both
a Hewlett-Packard and a mil-spec anti-static test.  However,
when we used one of the boxes to store chip resistors, we 
noticed that they would stick to the top and sides of the box,
as if being held by static electricity.  We could not measure
any conductivity of the film on the 10 Megohm scale of an
ohmmeter, even with the probes a millimeter apart.

The vendor claims the parts are being held to the top of
the box by the "surface lubricity" whatever that is.
Can anyone out there enlighten us about this buzzword.
Any opinion as to whether the box is or is not static proof?
