Thermal insulation bags through what principle to achieve the effect of heat insulation and heat preservation?

1.The principle of thermal insulation bag.

Many people know that the cooler bag can keep the temperature of the items unchanged, but do not know the principle behind it. As a matter of fact, the principle of thermal insulation of cooler bags is related to the bad conductor of heat. After reading Chiterion's article today, you will have a better understanding of the principle of insulated bags.

A poor conductor of heat is a substance that does not conduct heat easily and has excellent insulating properties. Common poor conductors of heat include air and vacuum, and cooler bags utilize this property. Cooler bags achieve the effect of heat insulation by filling the internal space of the bag with air or vacuum. Air or vacuum as a poor conductor of heat, can effectively isolate the temperature difference between the outside and the inside, to prevent the transfer of heat, so as to achieve the effect of heat insulation and cold insulation.

2.The material selection of cooler bag

Cooler bag material is also the key to ensure its thermal insulation performance. Common cooler bag materials include polyurethane, EVA, PEVA and so on. These materials have a certain degree of softness and elasticity, can be suitable for different sizes of items, but also has a certain degree of thermal insulation properties.

When choosing cooler bags, you can choose the material and production process according to the actual needs and use scenarios, in order to achieve the best thermal insulation effect. At the same time, the sealing of the insulation bag is also an important factor to ensure its thermal insulation effect. Therefore, the production process and sealing requirements for the cooler bag also need to pay extra attention.
