Truly antistatic bag?

Yeah, ok. The pink ones can't stop ESD discharge through the bag, but they dissipate surface charge. Which makes them antistatic bags, but not ESD shielded/proof bags? 

Yes.  The silver bags provide a barrier that protects the things inside the bag from static discharge outside the bag.  The bag doesn't protect its contents against static buildup inside the bag.  That is why everything that goes inside the silver bag needs to be static dissapative (or anti-static).  Hence the pink bags, bubble wrap, foam, etc.  They are safe to use as packaging inside the protected area.

It is the same thing with an ESD workstation.  You don't want to bring materials into the work area that can hold a static charge into the ESD safe area.  So when you receive your box from digikey, you are supposed to unpack it *outside* the ESD work area, then bring the silver bags (and only the silver bags) to your workstation, then open and unpack them there.    Likewise, non-ESD sensitive parts like resistors and capacitors should still be packed in static dissapative bags so that you can safely bring them into your ESD workspace without damaging other components.

Of course this is all the ideal practice.  It is important for production areas, or when working with high sensitivity devices like laser diodes and GHz amplifiers.  What you do in your home workshop is up to you.
