The most common type of insulated lunch bag is the thermal lunch bag, which is made from materials such as polypropylene or insulation foam. These bags are filled with enough food to feed a small person and then sealed shut with either an airtight seal or a zip lock. Thermal lunch bags work by trapping the heat generated by your food inside the bag, keeping it warm or cold for hours or even days.
Other types of insulated lunch bags include the cold pack lunch bag and the drink cooler backpack. The cold pack lunch bag is designed to keep your food cold for up to 12 hours, while the drink cooler backpack can keep your food cold for up to 24 hours. Both of these types of bags are filled with ice packs and then sealed shut with an airtight seal or a zip lock.
