Yes, the celophane has a purpose, otherwise Rema wouldn't spend dough on it. The cellophane works with the foil to keep the glue from drying. Removing it is necessary after the patch is applied, to speed curing and form a permanent bond. Rema also recommends "stitching" down the patch to improve the bond. They make a tool for it but you can do the same by rolling the rim of a cup or dish back and forth all over the patch. Stitching also shatters the cellophane which will mostly fall off by itself.
