I suppose this is context-dependent. If you're just talking about a gang of PCs is out somewhere causing their usual havoc, and a gang of NPCs needs to capture the PCs and the PCs wouldn't want it, then all the responses so far work.
But, what if the PCs have some allies who have been captured or who are facing immediate death? Perhaps some charismatic NPC offers the party an exchange--they surrender and the ally lives.
Or, suppose the PCs contain many lawful members and a paladin. Some group members have broken local laws for which at least temporary custody is the issue. An NPC law enforcer could talk to the paladin saying something to the effect of "It's your legal duty to turn yourselves over, it would bring dishonor upon you not to."
Capturing a party depends entirely upon context . . .
