Translation help from Quebecois?

I'm working on a poster for a local recycling center and I need to clarify that books are recyclable - but only soft cover. Do you use the word couverture or jaquette in Quebec? How can I clarify hard vs soft cover? Also, if I say that "bo�tes de carton (pas de carton ondul�)" are recylable, would that make it clear that you can recycle things like cereal boxes but not corrugated cardboard? Merci a l'avance!
