Psychiatrist women blame in film (10)

I believe the answer is:

shrinkwrap

I'm a little stuck... Click here to teach me more about this clue!

'film' is the definition.
Although both the answer and definition are verbs in their base form, I can't understand how one could define the other.

'psychiatrist women blame' is the wordplay.
'psychiatrist' becomes 'shrink' (informal term for a psychiatrist).
'women' becomes 'w' (standard abbreviation).
'blame' becomes 'rap' (synonyms).
'shrink'+'w'+'rap'='SHRINKWRAP'

'in' acts as a link.

Can you help me to learn more?
