When you open a food bag, but don't use it all in that first setting, how do you close it back up? Especially if it isn't a bag designed to close.
You can buy the chip clips. I've also used office clips (the metal, black and silver ones) which work even better than most chip clips I've tried.
Another option is to open the bag by cutting a strip across the top. Then use that strip as a tie to close the bag.
Even if you have to cut that tie off to open the bag the next time you need it, you can just cut another strip from the top to close it the second time.
