Chip bags SUCK!
Most are made out of several layers of plastic. Some have aluminum and plastic mixture. All have unregulated packaging.
And they are so hard to recycle, that most chip bags ARE NOT recycled.
So as I eat the last of my beloved Baked and Sun Chips, I bid a farewell. For I will only crunch a chip if they are homemade or somehow, somewhere, come in a cardboard box.
