Wrapping material is secured by super tape after repacking (6,5)
I believe the answer is:
tissue paper
'wrapping material' is the definition.
(tissue paper might be used to wrap things)
'is secured by super tape after repacking' is the wordplay.
'secured by' indicates putting letters inside (inserted letters are held or secured).
'after repacking' is an anagram indicator (letters packed or arranged differently).
'super'+'tape'='supertape'
'supertape' is an anagram of 'tsuepaper'.
'is' inserted inside 'tsuepaper' is 'TISSUE-PAPER'.
(Other definitions for tissue paper that I've seen before include "delicate sheets" , "Wrapping for delicate objects" , "There may be a valuable article in it!" , "Kleenex" .)
