What Does An Insulated Bag Do?
An insulated or cooler pack is meant to maintain the temperature of its contents like food, beverages, medicines, etc. So, they can be used to keep food warm during traveling, deliver medicines, and keep drinks chilled on hikes. An insulated bag barriers the transfer of heat through its walls thus the temperature stays constant for hours.
How Do Insulated Bags Work?
There are three types of insulation materials used in making a bag insulated; foam, fiber, and aluminum. These materials don’t let the heat and moisture transfer through the walls of the bag’s pocket. Due to this, warm food stays warm and cold drinks stay chill.
For example, Dakine cooler backpacks have an aluminum lining in the pockets that maintain the temperature for almost 8 hours. Yes, insulation bags have some limits in maintaining the temperature within the pocket. Actually, they don’t build a complete barrier, they slow down the heat and moisture transfer for a few hours.
How Long Do Insulated Bags Work?
As I told you, the bags can’t barrier the temperature change completely, they just slow down the heat transfer. Due to this, you may observe, the packs are keeping the temperature constant for a few hours. It’s been observed that they are able to maintain the temperature for around 8 hours. With premium lining and design, a bag can hold the temperature change for up to 12 hours. One can’t expect more than this time limit by an insulation bag.
Do You Need To Put Ice In An Insulated Bag?
To keep your drinks chill for a longer time, you need to put ice in the insulated pocket. The bag resists the change in temperature which leads to the slow melting of the ice cubes. Therefore, the beverages will remain chilled for a longer duration. However, the drinks will remain cold even if you don’t put the ice inside but it will be for a shorter duration.
