It's possible that if you heat the patch up, the plastic will peel of, leaving a sticky back. The patch could then be stuck to your shirt. This is how some of the emblems are attached to the uniforms I sell. The heat would probably need to be greater than that of a standard iron though.
I put an iron on it,then peeled it off with some tweezers. Worked great!
