Actually those things can be printed with foils. You will find foils commonly printed onto a lot of consumer packaging on top of a laser printed base.

Pedantic details aside, the manufacturers of the foils and vinyls to which you refer have their own unique colour/material collections that intersect pantone to some degree, and so they provide a separate "closest pantone" mapping. Given enough pressure I suspect they would adapt faster than pantone are gambling provided an obvious enough alternative.
