I don't know what the item is, but a return does mean you send back the item exactly in the same condition as received.
Cling film does not seem sufficient? Do you mean the packaging, because you can ask for any used sturdy box from say a supermarket, or shoe shop if the item will fit inside.
If you mean the actual box the item came in, you'll need to ask the seller if they will accept it without its original box as they item may have lost some value for resale.
