Is it related to the anti-static properties (and therefore "all" pink bags are static-dissipative)?

Or is it simply a distinguishing colour added during manufacture which may also be applied to normal polythene?

  • \$\begingroup\$ @Kortuk given that I don't know why, depending on that it may be also a matter of regulation, and then it may be suitable... \$\endgroup\$

    \$\begingroup\$ Pink plastic bags for electronics aren't static dissipative at all. They just don't GENERATE static. You want the metallic silver ones to actually protect your boards when transporting them around. \$\endgroup\$

  • \$\begingroup\$ @AndrewKohlsmith isn't that the definition of static dissipative? As opposed to anti-static, the silvery bags that actually protect against ESD. \$\endgroup\$

    \$\begingroup\$ Yes, I probably should've written static dissipative, rather than just putting quotes around "anti-static" - what's the consensus... should I modify the question accordingly \$\endgroup\$ Mar 20, 2012 at 20:53

These bags are pink for identification purposes. These bags prevent static build up, but do not protect their contents much from external sources of static. There are also silver bags that protect from those external sources and blue bags that are almost the same as the pink ones but work at a greater humidity range.

  • \$\begingroup\$ @KalleMP late here, but the black grid pattern is usually carbon based conductors. I think they are between the two types, but tending towards protection like the silver bags. \$\endgroup\$ Jul 7, 2016 at 14:03
