The Technology Behind Insulated Cooler Bags & Its Uses
Initially, the ice chest was used by travelers, and others hanging out at beaches were made from galvanized metal. Later on, it was made from hard plastic. Essentially, it was made with a double-walled layer with dense styrofoam in between that helps to keep the meals inside it, cooled for a long while. That is still the concept behind how insulated cooler bags work.
After that time, styrofoam was deemed a suitable insulator; however, it was not thick enough to
maintain the temperature inside the vessel for a long period. Another reason why styrofoam was not an adequate enough insulator was that styrofoam easily dents away and gets broken. This is why a hard layer of high-quality plastic layer had to be encapsulated to prevent it from causing breakage. This hardshell case is also extremely heavy to carry around, which makes this a design flaw, and inconvenient for people to carry around.
In contrast to these galvanized metal or styrofoam, insulated cooler bags are not as rigid in shape or heavy to carry around. Instead, they are made from flexible fabric materials such as polyester, which is resistant to water and can hold the temperature constant within. The cooler bags are lined inside with a heavy-duty foil, which works best for keeping the food inside cool or warm as intended.
And if you look in between these layers, there’s flexible foam, which is thin in size but dense enough to maintain the internal temperature as well. Usage of this technology allows having a bag that is light in weight, is flexible and thin, making it easily convenient to transport materials inside it. Since it makes use of lighter materials to make, manufacturers can produce a wide variety of sizes and shapes of these bags as opposed to the few hard-shelled plastic cooler kegs and galvanized metal ones.
