Lunch Bag Heat And Cold Preservation Test

LUNCH BAG HEAT AND COLD PRESERVATION TEST

Heat preservation test:

Put the cooked heat lunch in the lunch bag at 8 o'clock in the morning, tighten the zipper and save it, then go to work, and put it in your drawer when you arrive at the company.

At around 12 o'clock, opened the bento for lunch, it was still warm, so I can eat it directly! For those of us who work, it is especially suitable for companies that do not have microwave ovens. Since it is to test the direct effect of the thermal insulation bag, no warming measures are done on the outside of the lunch box, and it is placed directly in the thermal insulation bag.

On the day of the test, another bento with the same meal was not placed in a heat preservation bag. After the same time, placed in the same position, the meat in the lunch box was frozen, and the soup was completely cold without temperature.

Cold preservation test:

Use it with an ice pack. Place the ice pack flat in the refrigerator or freezer. After freezing, put it in an insulation bag, place it on top or side of food, beverages, fruits and other items, and then tighten the zipper. After about 6 hours, the ice pack has completely melted, and the food and beverages in the pack are still at the temperature just taken out of the refrigerator.
