Because it is to test the direct effect of the insulation bag, no warm measures are taken on the outside of the lunch box, and it is placed directly in the insulation bag. If you can put cotton clothes and other items in the bag, it can also enhance the heat preservation effect! (Related to outdoor temperature).

After freezing, put it in an insulation bag, place it on top or side of food, beverage, fruit and other items, and then tighten the zipper.
