Regular high charging packaging is not to be in an ESD Protected Area.  So
even if you have a bag of bolts [non-ESD sensitive items] in an EPA, the
bolts are should be in a pink poly bag or similar packaging.  The shielding
property is required for storing or transporting ESD sensitive items outside
the ESD Protected Area.

ANSI/ESD S20.20-2007 says to go to ANSI/ESD S541 for Packaging.  Both are
available at no charge to download from www.ESDA.org.

"ESD protective packaging shall be in accordance with the contract, purchase
order, drawing or other documentation. When not specified by the above
documentation, the organization shall define ESD protective packaging
requirements, both inside and outside the EPA per ANSI/ESD S541."  [ANSI/ESD
S20.20-2007 section 8.4]

ANSI/ESD S541 section 6.1 Inside an EPA "Packaging used within an EPA (that
satisfies the minimum requirements of ANSI/ESD S20.20) shall be:
1. Low charge generation.
2. Dissipative or conductive materials for intimate contact."

ANSI/ESD S541 section 6.2 Outside an EPA "Transportation of sensitive
products outside of an EPA shall require packaging that provides:
1. Low charge generation.
2. Dissipative or conductive materials for intimate contact.
3. A structure that provides electrostatic discharge shielding."

I have the understanding that pink poly, while being a non-generating 
material, does not or is not as good at protecting devices from static 
discharges as conductive black or metalized film. Am I mistaken or is this
not a 
concern in this application?

have both the pink poly and black ESD style of cap plugs. What are any of 
your experiences with contamination associated with using pink poly? As
