Wrapper's roll (4)
I believe the answer is:
tape
'wrapper's roll' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for tape that I've seen before include "Strip, magnetic, video, etc." , "that race winner may break" , "Record; finishing line" , "Binder" , "Breast this first to win a race" .)
