Sun Chips is out with another biodegradable bag, but this time it swears you won't need ear protection. Frito-Lay backtracked on last year's really, really loud version amid complaints, ridicule, and poor sales. Now the company has begun putting a new biodegradable bag on shelves (for the "Original" chips), and it says the noise is on par with regular bags thanks to a new adhesive between the crinkly inner/outer material, reports Fast Company. We'll see. (More Frito-Lay stories.)
