Hot Bags for Food Delivery are Changing the Face of Food Service

You know the drill:  It’s Saturday night, you’re about to watch a movie or the big game, and hunger strikes.  Only you don’t want to go out.  You’re already in your comfy clothes!  The only options are cook something yourself (not going to happen at this point) or order in delivery food.  The problem is, delivery food is notorious for being less-than-appealing by the time it gets to you.  The food is lukewarm at best, soggy and lifeless.  Not very appealing, is it?  Nevertheless, if you want to be able to eat dinner on the couch without cooking, it’s the only option.  Fortunately, there is an answer.  Thanks to the development for hot bags for food delivery, hungry movie-watchers can enjoy their favourite delivery food hot and fresh, just as it would be if they were eating it in the restaurant itself.

In the past, food-delivery bags simply kept in the heat that was generated by the food itself.  As the food inevitably cooled, the bag’s ability to retain any heat diminished.  Those bags cannot retain heat that doesn’t exist. 

There’s a new generation of food delivery bags that solve both the problem of heat loss and of soggy, lifeless food.  These bags have thermal abilities.  That is, they actually generate their own heat rather than relying on the retention of residual heat from the food to keep the food warm.  This is a true innovation in the food-delivery scene, allowing at-home diners to get much better-quality food from their delivery service.

The effect of keeping the food hot and fresh is achieved through induction heat.  Essentially, this works by the transfer of energy from the originating source to an inductive object (the food).  Molecules are forced to move quickly in a back and forth motion, which thus creates friction. That friction, in turn, creates the heat that is used to keep the food hot.  Just as you would create friction with two sticks to eventually generate enough heat to spark a flame, friction creates the heat that keeps the food inside the deliver bag hot.

Further, the thermal nature of the bag locks in the heat, keeping the food hot for 30 minutes or even longer.  The food, however, does not continue to cook.  This is important because if the bag simply create a hot environment the food would continue to cook and be dramatically overcooked when it reached the customer.  These bags feature temperature control capabilities, which allows them to keep the food at the same temperature it was at when it was placed into the bag.  It does not get colder nor does it continue to cook through an increase in the temperature.  The temperature stays constant long enough for the delivery person to make the delivery safely.

This is in contrast to the previous generation of thermal delivery bags.  Those bags are designed only to hold on to existing heat; they do not generate heat of their own.
