The Rema patches I've used have a thin slit in the cellophane at the
center of the patch. Stretching the tube/patch after the repair
splits the cellophane at the slit and makes it easy to remove if
desired.

I just wonder about the best practice WRT removing the cellophane. I suppose
it's there to keep the patch from drying out. But I'm sure it also helps
protect it from peeling off the tube, and/or sticking to the tire. OTOH, I
wonder if peeling it off helps the patch cure faster.
