How often there is a need for ready-made food or cooled drinks! Food at high temperatures is spoiled, and water, even placed in the shadow, is inevitably heated. Solve the problem of preserving provisions will help you, refrigerators bags - comfortable containers or containers that can maintain a low temperature. Before purchasing this device, we recommend to familiarize yourself with its possible parameters. The article will be a guide to you among the manifold of the bags presented in the market.

First of all, it is necessary to distinguish the concepts of the refrigerator bag and thermo. Usually these concepts are used as synonyms, which is not entirely true. The thermosum works on the principle of thermos, that is, at the expense of its reflective properties. Thus, the heatmamus retains both cold and heat, and the duration of the support of the desired temperature is inferior directly to the refrigerator. The refrigerator bag is equipped with batteries, which create a cold inside the tank. Therefore, for a start, you need to decide for what purposes you want to purchase an isothermal bag and how long the temperature is to maintain you.

Volume. Bags are very small (from 2 liters) and large (40 liters). If you are planning hiking, picnics or just rest without the ability to transport products, choose small mobile bags - 10-20 liters. If you need to keep the freshness of the pair of sandwiches, you will be fine with a micro-bag in 2-3 liters. The most voluminous refrigeration containers are designed to transport edible supplies by car.

Material. An important factor affecting your choice should be the material from which the bag is made. High-quality bags are made of synthetics: polyester, nylon, PVC. These materials have the ability to reflect heat, light, moisture, and are also easy to clean. The inside of your mobile refrigerator should be a lining with thermo- and injector properties. Conventional materials will reduce the cooling capacity of the bag no less than 2 hours. A thermal insulation foam is poured into the space between the inner and outer layer. Spend the walls of the bag. If you do not feel the density and thickness of the walls, it means that the manufacturer saved on the inner layer, which will affect the functionality of your acquisition.

Batteries. Battery-refrigerator batteries are special containers filled with saline fluid. In a medium-sized bag (10-20 liters), the optimal amount of cooling batteries is 4-5. However, the cold in the container will be maintained longer with a larger number of batteries. For the quality of batteries, it is not worth worrying. Their internal composition is almost eternal, and the service life depends only on the strength of the container.
