Sun Chips recently abandoned almost all of its biodegradable bags because they were too noisy and people freaked out. The bags were made out of nonspecified "plant material."
Now, across the pond, a British chips-maker—they call them "crisps," because in their daft world, chips are fries—is talking about making chip bags out of potato peelings. There is no indication how loud a potato-peel chips bag might be, but: the poetry! It'll be almost like eating a potato.
