I'm sending this e-mail for a partner.

I recently bought myself a 3M static event detector to evaluate my static
shielding bags.
What I do is insert this device into the bag and with a "ZAPPER", I give
this bag an electrostatic discharge ranging from 2kV to 20kV.  If the LCD
display from the device turns red, a static event as been recorded.  How
strange?  Most of our bag failed this simple test.  My questions are:

1) Is it possible that I'm using the wrong test to verify the shielding bag?
2) Why the bag is called "static shielding" when a discharge can go through
the bag and make    the display turn red (ESD event detected)?
3) Is there another way to test the bag?
4) If a static event was detected with the device inside the bag, is it
possible that when this bag is manipulated by personel, a discharge may
dammage the sensitive product inside the bag?

Any comment or answer would be very appreciated.

Thanks
