Buyer Guide to Choose Best Thermal Bags

The insulated bags are heat-insulated bags that keep food or drinks warm or cold. They are particularly useful accessories in summer, when you bring cold dishes or drinks to the beach.

But also in winter when you have lunch outside for study or work and want to enjoy a hot meal. In spring, however, the season of picnics is indispensable for bringing everything you need for an outdoor lunch.

Those small, soft, and with handles or shoulder strap, are used daily by those who have lunch outside the home, while the large ones, rigid or in the shape of a backpack or trolley , are particularly useful for those who love long trips and excursions.

Currently available on the market are the classic models that are used with icicles or electric thermal bags, which work through a socket and which can also be used in the car.

Types Available

The models currently available on the market are divided into ordinary thermal bags and electric thermal bags, lately very popular.

The first are those made with heat-insulating materials that are used to keep food and drinks fresh through popsicles, brick-shaped utensils that, before being in the main pocket of the bag, must be kept in the freezer compartment.

Thanks to the icicles and the different materials that make up the bag, everything that is inserted inside it is kept at a cold temperature, ideal for preserving its freshness, for a time ranging from a minimum of 3 up to a maximum of 8 consecutive hours, until the internal temperature reaches the external one. Generally, these models are used for picnics, excursions, or trips out of town.

On the other hand, the electric coolers work through a standard socket for the electric current or the cigarette lighter of the car or camper, ensuring the maintenance of the optimal food storage temperature for up to 24 hours or until it is unplugged.

Precisely because of this characteristic, they are particularly suitable for long journeys or excursions that last a few days. In this regard, if you decide to buy a model belonging to this category, it is essential to evaluate the engine’s power and the duration of the refrigeration that the bag can guarantee once it is unplugged.

Soft models and rigid thermal bags are available, the former made with insulating materials found inside, while the latter in hard plastic.


As for the available shapes, in addition to the traditional ones with shoulder strap or handles, backpack -shaped or trolley- shaped ones are available, beneficial for those who have to take large quantities of food or drinks away from home for a trip or an excursion without too much fatigue. They are typologies, therefore, not suitable for daily use.

Capacity and Dimensions

The capacity of a thermal bag is measured in liters. Obviously, in this case, it all depends on the use you intend to make of it and, before buying one, it is essential to have a clear understanding of its purpose (it will be used to bring lunch to work, for a picnic with the whole family, for an excursion or a long trip, etc.)

The more significant the liters, and therefore the capacity, the more foods or drinks that can be inserted inside the main pocket.

Consequently, if you want to buy one to be used daily for work or university, it is advisable to choose a model with compact dimensions. If, on the other hand, the aim is to face a trip or to organize a picnic, you must necessarily choose a large one that allows you to carry all the food and drinks you need.


The materials must necessarily be resistant and of high quality. The best thermal bags are generally made of an external stain- resistant, water – repellent and dirt-resistant material, fundamental characteristics not only for storing food safely and hygienically but also for washing and cleaning them quickly and effortlessly.

As far as the internal materials are concerned, instead the most effective ones which guarantee optimal maintenance of the storage temperature are made up of several layers.

Generally composed of an innermost one equipped with an aluminum foil and an intermediate one consisting ofEPE foam, with a thickness that varies from one model to another. It is precisely this particular foam that keeps food and drinks fresh.

Insulation Capacity

The insulation capacity, both for standard and electric models, must be optimal. Precisely for this reason, it is essential that not only the materials are of high quality.

But that also the hinges and any finishing present are made in such a way as to ensure that there is no temperature exchange between the inside and the outside. The bag must always be closed tightly.
