The "green film" is identical to the old laser foil. It is a mylar film with
a metalized fusible coating. Part of its success is just by remelting the
toner and pressing it down again
You can get the same effect by using the release sheet from laser labels by
Dennsion and re-ironing the pattern or running it though the laminator.

There are some craft hot air "embossing" tools that also work well.

Note, you do have to have good coverage of the copper by the toner. One of
my laser printers does a very poor job with large solid areas.
