Plastic plug and plastic lab tape (9)
I believe the answer is:
adaptable
'plastic' is the definition.
(thesaurus)
'plug and plastic lab tape' is the wordplay.
'plug' becomes 'ad' (as in plugging a product).
'and' says to put letters next to each other.
'plastic' indicates anagramming the letters (plastic can mean easily moulded).
'lab'+'tape'='labtape'
'labtape' anagrammed gives 'aptable'.
'ad'+'aptable'='ADAPTABLE'
(Other definitions for adaptable that I've seen before include "Able to adjust to new conditions" , "Happy to fit in" , "Able to be modified" , "Open to modification" , "Can be converted or applied to other uses" .)
