......when the tube with new patch is inflated in the tire (100 + lbs)psi,the cellophane lets the new patch slide against the interior tire liner...this keeps the patch from getting friction and being pulled up-sort of a lubricant. But as stated above, Rema does say to remove cellophane and apply talc to prevent friction.
Most people don't let the glue dry long enough before installing patch,also put pressure with thumb for longer period of time.
