Refrigerator bag - an indispensable assistant on the road

The word "refrigerator" causes us to involuntarily associate with a cumbersome unit designed to store a large number of products. But, for example, people often go to out-of-town picnics, immediately comes to mind and such an object as a cooler bag.

This item is used to transport a small amount of products, for the preservation of which low temperature is required. More often it is used to transport meat for shish kebab, drinks, sausages, etc. Because the refrigerator bag is very convenient to use and has a wide price range in which everyone can pick up a thing for himself and taste, in our country popularity These accessories are growing year by year.

In truth, not all refrigerated bags would be properly called refrigerators. Most of them are thermal bags or thermal containers, because they do not contain a cooling element as such, and therefore they are only able to maintain a lower temperature for some time.

The refrigerator bag can keep the low temperature inside from 5 to 12 hours. To increase this period, special cold accumulators are used , which are small briquettes filled inside with a special heat-intensive solution. Before use, they should be held in the freezer for about 10 hours, then placed in a refrigerator bag. As an alternative to briquettes, dry ice can be used .

But still the term "cooler bag" is already very firmly entrenched in the minds of our fellow citizens, so we will use it later.

To another version of the bags-refrigerators can be attributed thermo containers. They are usually made of plastic, and their volume is from 1 to 150 liters. The walls of the container are filled with polystyrene foam, and from above it is closed using a sealed cover. Compact boxes are equipped with one handle located in the middle. Containers of medium size have two handles located on the sides. Such devices are capable of maintaining a constant temperature of up to 12 hours.
