what is the American equivalent?

I'm hoping someone of our Australian correspondents can help
me with a material I've seen specified in some directions,
but can't identify. The directions to make your own pleater
board call for

"Vilene Fusible Badge Backing 1050HF",

and googling this only results in a pointer to hte same site
with the directions.

As I'm about to assemble (with help) about 200 pleat front
cummerbunds, this looks like just the tool to help, if we
can get an adequate substitute for whatever his is. My best
guess is a really heavy interfacing, perhaps craft bond, but
if anyone knows for sure I'd be grateful.

Thanks
