They never go into details on the mechanics. You kind of just need to go off assumptions with certain things. For instance, we can assume the traps use a similar containment system as the larger containment unit, just smaller and not suited for long term storage.
As for numbers, it depends on the continuity. In the movies (and the IDW ongoing comics), a trap can handle one or two with little problem, but things get kind of... explosive if you cram too many in there. The cartoons made the traps fit the need of the script, but couple hold way more standard ghosts than the movie versions, but there were instances of very powerful entities breaking free of the trap.
