2. Material of cooler bags
1. In the manufacture of cooler bags , in order to make the bags have better thermal insulation effect, the selection of airtightness and materials is particularly important. In the market, we can often see the use of aluminum foil as the surface or inner fabric of cooler bags. The advantage of aluminum foil is that it can block radiant heat, allow heat to pass through conduction and convection, and maintain the temperature in the bag.
2. In addition, we can also see in the market that instead of using aluminum foil, a material called PVC is used. Using this material can make the cooler bags look like a normal bag, and the shape also takes into account the daily use. The limitation is only used in the heat preservation function, but the higher the temperature of the PVC material, the more likely it will become soft, and the plasticizer will be dissolved, so this material is more suitable for use in ice packs.

The cooler bags generally has a thermal insulation time of more than 6 hours, which is better than the traditional ordinary iron insulation box and plastic box. It is very convenient to use, clean and hygienic.
Therefore, we can choose the insulation bag that suits us according to our actual needs.
