Thermal Food Carrier Bags To Keep Food Cold
Thermal food bag have one or more layers of air are sandwiched between the inner and outer layers of thermal food carrier bags, so it is difficult for heat to enter or leave the thermal bag. In addition, thermal bags are sometimes coated with reflective material on the inner and outer surfaces, which reflects the radiated energy back.
This food carrier bags can maintain low temperature or high temperature for a long time.
In addition to being reusable, the purpose of using thermal bags is that thermal food carrier bags can keep hot food and cold food longer than ordinary plastic bags.
