It is somewhat common, but usually as a sub-packaging rather than the main e.g. chocolates are commonly individually wrapped in aluminium foil, it's also commonly used for meal trays (but I guess has become less common due to microwaves?).

Sealed packets are also commonly foiled though mixed with plastic (for e.g. quick-close bits). Dunno how that works out for recycling, just burn out the plastic?
