Coller bag test

- Mar 08, 2019-

Insulation test: Put the freshly cooked food into the insulated bag at 8:00 in the morning, tighten the zipper to save, then go out to work and put it in a place without wind. Around 12 o'clock, open lunch for lunch, or warm, want to eat directly! For those of us who work, it is especially suitable for companies that don't have a microwave oven. Because it is a direct effect of testing the insulation package, there is no warming device outside the lunch box, which is placed directly into the insulated bag. If you can put cotton and other items in your bag, you can enhance the insulation! (related to outdoor temperature).

Note: On the day of the test, eat another meal of the same food instead of in a heat-insulating bag. At the same time, placed in the same position, the meat in the lunch box was frozen, the soup was cold, and there was no temperature.


Cold insulation test: Use with ice packs, place the ice packs flat in a refrigerator or freezer, freeze and freeze, put them in a heat preservation bag, and place them on the top or side of food, beverage, fruit and other items, and the zipper can be tightened. After about 6 hours, the ice pack is completely dissolved, and the food and beverage in the bag is like the temperature taken out of the refrigerator (related to indoor and outdoor temperatures).
