Around a minute behind time to get coat? (8)
I believe the answer is:
laminate
'coat?' is the definition.
(to laminate is to coat in plastic)
'around a minute behind time' is the wordplay.
'around' means one lot of letters goes inside another.
'minute' becomes 'min' (abbreviation).
'behind time' becomes 'late' (I've seen this before).
'a'+'min'='amin'
'amin' placed inside 'late' is 'LAMINATE'.
'to get' acts as a link.
(Other definitions for laminate that I've seen before include "Split into layers; cover with protective material" , "Manufacture by layering" , "Thinly cover" , "Sheet of material made by bonding two or more sheets" , "Material made up of bonded sheets" .)
