Display Shelf Life Bag / Food bag

Display Shelf Life Bag

This food bag is using plastic zipper to sealing. Anytime you cannot finish the food, just use the zipper to seal the bag. In order to help people more directly recognizing the shelf life of food, the plastic zipper surface is coated with chemical. This coating will oxidize and discolor in the air. Also, as the food shelf life is shortening, the color on the zipper will gradually change as well.
