Cooler bags are insulated containers used to keep temperature-sensitive products cool during transport. They are commonly used for medical food, vaccines, and pizza delivery. The insulation helps maintain hot and cold temperatures, and metal padding can transfer escaping heat back to its source. Ice packs can be added for extra cooling. Personal cooler bags are also available for lunches on-the-go.
A cooler bag is an insulated container used to keep temperature-sensitive products cool. These types of bags are most commonly used to safely deliver medical food and vaccines. Insulation in a cooler bag ensures that both hot and cold temperatures are maintained during the transport of its contents.
To ensure safety, the temperature of many foods must be kept constant. When sensitive or perishable foods are moved from one location to another, a cooler bag is a temporary source of temperature control. For example, pizza delivery bags use insulation to keep the food warm so it doesn’t spoil when the customer receives it.
Pizza delivery is one of the industries that makes heavy use of thermal packaging. Since delivery drivers may need to locate addresses they don’t know, the thermal insulation in the bag ensures customers aren’t dissatisfied with cold food. Cooler bags keep food fresh and give the impression that it has just been taken out of the oven or microwave.
The inside of a cooler contains insulating material, often in the form of padding made of metal material. For foods and other items that need to be kept warm, the metal material helps transfer the escaping heat back to its original source. The padding and metal material also contain the heat inside the cooler bag as long as it remains closed. Thermal insulation is a temporary solution to maintain temperature control and shouldn’t be replaced with long-term solutions, such as a refrigerator.
In addition to retaining heat, thermal insulation can also keep items cold. Perishable and frozen foods, as well as vaccines, may need to be kept at certain temperatures during transit. Ice packs can be placed in cooler bags to help complete the isolation. An insulated container is a good solution for small shipments of vaccines or food products that only have to travel short distances.
Another type of cooler is available for personal use. Some of the lunch bags or bags available for consumer purchase use thermal insulation. This can come in handy for people who want to bring their own lunches to work sites, but don’t have access to a refrigerator. Delivery drivers who work outside of an office and are constantly on the go typically find insulated lunch bags to be a great convenience.
