To make thermal cooler bags, in order to have better insulation effect,the airtightness and materials are very important. In the market, there are many thermal cooler bags that use aluminum foil as the surface material  or lining.  the features of the aluminum foil is its obstruction.It can block the thermal radiation. It can help to keep the temperature through its good heat conductor and convective characters.
There are many kinds of thermal cooler bags and insulated bags in the market. Do you know how to choose a proper bag for keeping stuff warm or keeping stuff cold?
Other than aluminum foil, we also find another material, PVC, used as an insulation material in the market. It can make the insulated bags look like a normal bag. When we are looking for the functional bag of maintaining the temperature of the stuff, we also consider the outlook of the bags as well. However,  the high temperature will soften the PVC material and release Plasticizing . It is normally used for cooler bags.
Considering the user’s health, we choose another food grade material, PEVA. It is an environment-friendly material. It is  soft and also it won’t release Plasticizing agent in the high temperature environment. It is safe for our health and living environment.
