Tie frozen food bags easily, without having to go searching for a clip or rubber band. When you open a bag of frozen peas or tater tots, you’ll either tear off a narrow strip (thank you, perforated edges!) or cut it off with scissors. Hold onto that strip, because it makes a perfect tie for the bag when it’s time to put it back in the freezer. The plastic is already meant for cold temps (it’s part of a frozen food bag, after all), so it will adhere easily to the rest of the bag.
Just press the air out, twist the top of the bag, and tie it off.
