I believe the answer is:

packer

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

'he gets things all wrapped up' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.

'he' is the wordplay.
I cannot really understand how this works, but
'he' could be 'ker' and 'ker' is located in the answer.
The remaining letters 'pac' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...

Can you help me to learn more?
