Store at home with film material (9)

I believe the answer is:

stockinet

'material' is the definition.
(stockinet is a kind of material)

'store at home with film' is the wordplay.
'store' becomes 'stock' ('stock' can be a synonym of 'store'**).
'at home' becomes 'in' ('in' can be similar in meaning to 'at home').
'with' means one lot of letters go next to another.
'film' becomes 'et'.
'stock'+'in'+'et'='STOCKINET'

(Another definition for stockinet that I've seen is " stretchy material".)

I've seen this clue in The Telegraph.
