There is a great video about static disipative and static shielding bagies from EEVblog.

Summary: “pink” bags and tubes just prevent static buildup (regular bubble or plastic wrap can generate hundreds or thousands of volts pretty easily just by rubbing; non-conductive foam is pretty nasty too). Silver/metalic baggies actually prevent external discharges or shocks from harming ICs inside. If you use a shielding bag, you still need to make sure all the materials inside will not build up a charge.
