I've been known to use Sellotape and fine tweezers to extract SIM cards from phones when some eejit tried putting the wrong card in.
Amazingly it worked!

It also works well as an EL dielectric for a while at least, and is just the thing (tm) for insulating PCBs when trying to install tiny modwires or rework tracks for some hack or other.
Kaptop tape is even better and has been even used in production for this very purpose.
