Definition and Purpose
A keep food warm bag, also known as an insulated food carrier or thermal bag, is designed to maintain the temperature of food items, keeping them warm and fresh for extended periods.
It typically consists of an insulated interior lining, which creates a barrier against heat loss, and an outer layer that protects the bag from external elements. The insulation material, such as foam or quilted fabric, traps air, which acts as a thermal barrier, slowing down the transfer of heat from the food to the surrounding environment.
How it Works
When warm food is placed inside a keep food warm bag, the insulation material prevents heat from escaping, allowing the food to retain its temperature for longer. The outer layer further enhances insulation by blocking cold air and wind from entering the bag.
This combination of insulation and protection ensures that the food stays warm and palatable even when exposed to colder temperatures.
