Of course, you plan your insulation package according to the size of your lunch box. It is generally the size of two lunch boxes arranged side by side. Don't be too crowded It is best to leave about one centimeter of activity space. If you are small, you can't put two at the same time. If it is bigger, you can put foam powder or cloth to fill the stable lunch box. You can take a ruler to measure the length and width of your two lunch boxes together, and then buy insulation bags according to this ratio.

Secondly, look at the depth of the insulation package. Generally, the overlapping height is about 5, and two lunch boxes are placed side by side, each weighing 5, so that one insulation bag can hold 10 lunch boxes. Secondly, the height can be higher, which is convenient for putting some small foods such as soup, porridge and cakes. Quantifying each knot is what you should do, which is convenient to carry and saves space!

Finally, the insulation package should have a portable place and a strap that can be carried on one shoulder. It's much more convenient if you go upstairs and downstairs or downtown. It's better to have a pocket next to the bag to decorate cards or business cards for promotional pictures. You should also consider the weight of the bag, 400g for a meal, 300g for the main course and100g for the side dish, which is about1000g and 2kg. 10 rice is 20 Jin, which is quite heavy. What if I go upstairs? Therefore, two meals are better. If I want to overlap five meals, it is also convenient to calculate. One bag is ten bags. How convenient.
