How Do Thermal Lunch Bags Work?

Layers are the ideas behind lunch bags. These bags are made from two or more layers. These layers help to trap air. Now, these layers of air make it hard for heat to move out. Some thermal lunch bags are designed with reflective inner layers.

The reflective layers bounce off the heat off each other; this really slows down the rate at which heat is absorbed, thereby slowing down the rate at which the bag loses heat. These layers of material are usually made from resilient insulating materials. Now, these could be PVC, Nylon or other waterproof fabric. The inner layers are usually thin, while the outer layers are usually heavy-duty materials.

How Do Insulated Lunch Bags Work?

Insulated lunch bags work in pretty much the same way thermal lunch box works. They are able to keep food hot and/or cold depending on how you want it by just some basic physics principles. This is the principle of heat conduction or better still heat insulation. Heat is transferred by three basic principles, convection, radiation and conduction.

Now the idea here is to make sure heat losses through these means are reduced to a minimum. That’s why the bags are made with two layers. In between the layers, (that is inner and outer), there can either be a vacuum, or an insulating material such as foam.

Thermal Lunch Bag vs. Insulated Lunch bag

So what’s the difference between a thermal lunch bag and an insulated lunch bag? Both terms are interchangeably used but meanings and purposes are slightly different from each other. A thermal lunch bag is also an insulated lunch bag.

If it’s not insulated, it will neither be able to keep anything hot nor cold. The difference is just in the names, nothing more. So an insulated bag is the same thing as a thermal lunch bag.

Here are some of the best lunch bags available at the moment. This, of course, is not an exhaustive list, but if you’re stumped on the choice for a lunch bag, then we’ve just given some guidelines. Before you make a choice, make sure that the bag you’re choosing matches your needs. We’d like you to share your experience, after you’ve used a bag, with other readers. Thanks.
