Why Can the Insulation Lunch Box Achieve Long-term Insulation for More Than 12 Hours?

Speaking of insulated lunch boxes, our biggest impression of it is probably that it appears in our daily life as a lunch container during work and school.

1. What is the principle of the insulated lunch box?

First of all, let's talk about the principle of the insulated lunch box. The principle of the insulated lunch box actually uses the principle of vacuum insulation. It is not difficult to understand the principle of the insulated lunch box.

That is to say, the heat preservation lunch box is a vacuum layer added to the double-layer stainless steel to form a vacuum insulation space. 

At this time, the collision frequency and intensity between the gas molecules and the gas molecules and the container wall of the thermal insulation lunch box will be relatively weakened. As a result, the thermal insulation lunch box reduces the heat transfer effect and achieves long-term high-efficiency insulation.

After we have figured out the basic thermal insulation principle of the thermal insulation lunch box, let's take a look at how the thermal insulation lunch box achieves the thermal insulation effect.

2. The process of making thermal insulation lunch boxes

In addition to the principle, another reason is the process of the thermal insulation lunch box. At present, various thermal insulation lunch box brands use different thermal insulation processes and different effects.

Some heat preservation lunch boxes use the microwave copper plating process. Although this process is one of many heat preservation processes for hot food heat preservation lunch boxes, this process is also the most effective way for continuous heat preservation.

Microwave copper plating is to plate copper on the inner wall of the insulated lunch box, which is equivalent to forming an effective thermal insulation layer on the inner wall, allowing the copper-plated surface to reflect heat radiation, thereby effectively reducing the entry of external cold air and reducing heat loss, so that it forms a thermal cycle inside.

With the help of the principle of health and advanced technology, the heat preservation time of modern heat preservation lunch box can easily reach more than 12 hours, and the food inside can be kept above 55 ℃.

In this way, even people living in Antarctica can still eat warm and delicious meals, not to mention us living in livable areas. With the development of thermal insulation technology for hot food insulation lunch boxes, our lives will inevitably become more healthy.
