Time Magazine's disposable paper (6)
I believe the answer is:
tissue
'disposable paper' is the definition.
'tissue' can be an answer for 'paper' (tissue paper is a kind of paper). I am not certain of the 'disposable' bit.
'time magazine's' is the wordplay.
'time' becomes 't' (abbreviation).
'magazine' becomes 'issue' (I've seen this before).
't'+'issue'='TISSUE'
Can you help me to learn more?
(Other definitions for tissue that I've seen before include "Thin, absorbent paper" , "Type of paper" , "Bodily matter" , "used to make up lies?" , "Absorbent paper, used as handkerchief, say" .)
