While here in the U.S. of A., SunChips' noisy (but biodegradable!) bag got tossed out by Frito-Lay, the Canadians get to keep theirs. Here, we see Frito-Lay Canada's sustainability chief telling you all about that decision.
Bonus: if you still think the bag is too loud, they'll send you a free pair of ear-plugs. As you'll all recall, the SunChips bag sent me into a paroxysm of moralizing and despair. This video will inspire no such outburst.
