Like what about plastic makes it impossible for electricity to flow through it as opposed to something like metal?

Electricity relies on *charge carriers*. Charged particles that move around in a material. Normally electrons, although there’s some odd exceptions.
For an electron to move, there has to be an open spot for it to move into. This spot cannot be higher energy, and if this spot is lower energy then once the electron moves there is will stay. So really, you need an open spot that’s the same energy as the occupied spot.
Most materials don’t have that. Their occupied spots are different energies from their unoccupied spots, or too far away.
