It's been around for at least 5 years.
If you want some then I know you can get it from Electus/Jaycar.
yeah been available at least that long, i used it about that long ago at work to make boards for a customer who wanted customised timers made up. They were my first introduction into using Press n peel film. Its not that hard to use really. Just make sure, as i said, to get the board nice and hot when ironing it on. And its NOT mentioned in the instructions, but you must print you artwork in MIRROR IMAGE (reverse) onto the film! luckily that was pointed out to me by my boss or I would've made that mistake first time i used it.
Available from Jaycar, packet of 5 sheets for $35.00 catalog no HG-9980, as is everything neede to make PCBs
