I've gotten thousands of these things in my Christmas deliveries, all strung together in long rows. I line them up, cut off the machine-sealed ends, then fold them and store them in a large ziploc-type bag. Just tear them off one, two, three at a time, as needed.
They make great poop bags for our small dogs, good for sanitary female-product disposal. Just watch dogs or cats with a penchant for enjoying such things, they aren't scent-proof enough for them. I wouldn't want them to eat pieces of the plastic! They are also awesome for storing any small non-food items, like screws, hairpins, coins, etc. Just roll them down and use a rubber band or twist tie to secure.
All reusable, convenient to grab a string of them in a hurry on the go, in the office, garage, car, bathroom.
This is a page about using air cushion packaging as a bath pillow. Next time you get air cushion packaging, don't throw it away. It makes a great waterproof bath pillow.
