Unfortunately, the city gets very upset about the recyclable materials being in plastic bags (something about it messing up their machines). I like it better this way because I don't have an indoor bin full of loose, used plastics and paper which feels unorganized and dirty.
I feel like these small, yet annoying, inconveniences hurt participation (in addition to the countless stories of plastics and garbage just being thrown into the same hole in the ground, or into an ocean patch off the coast of some other country).
