Paper airplanes work just like regular passenger planes and fighter jets: by redirecting air to keep themselves airborne. As long as a plane is moving quickly, its wings will redirect a lot of air downwards, which generates an equal upwards force (lift). This lift is enough to bear the weight of the plane against the pull of gravity. Your paper airplane launcher is effective because it gives the paper airplanes a lot of speed, and therefore a lot of lift — plenty to keep the planes aloft for lengthy trips around a room (or until they hit something!)
