I'm afraid I don't know what sort of plastic it is. I'm pretty sure its
not a polythene type though as its quite hard, and one side is very high

There was some sort of black rubbery stuff, possibly silicone, stuck to it
before, if that helps.


I've personally not had much success with hot melt, but at least it is
flexible (unlike epoxy). Hard and glossy could be acrylic or styrene so
solvent type glues sound possible. Gorilla glue is perhaps not flexible
enough?


The faster epoxies I use - 5 minute - are slightly flexible.
