Principle of operation

The operating principle of the temperature bag is very simple:

• it has a multilayer structure, one layer of which is made of insulating material;
• extension of the temperature regime for a certain period is achieved thanks to cold accumulators - plastic containers filled with salt solution.

Important! The larger the volume of batteries and the more qualitative they are, the longer the refrigerator bag will maintain the temperature at the optimum value.

The thermo bag can work for both cooling and heat. That is:

• in order to transport products in the summer - you must first cool the batteries;
• If you plan a trip in the winter - they need to be heated.

Important! In some inexpensive models of a thermosensor, batteries do not come bundled. In this case, it is better to buy them separately, since without them the resource of the refrigerator bag will be very small. To calculate the required number of batteries, it is sufficient to adhere to the following formula: 1 the container goes for every 5 liters of bag volume.

Choosing the suitable model

The refrigerator bag will function properly, provided that you initially correctly identified your requirements and were sensitive to the selection process. Here it is necessary to take into account such characteristics of the product.

Materials

For sale are both soft and hard models on the frame of polymers. According to consumers' feedback, one can draw a conclusion - hard models are definitely better than soft ones.

For the manufacture of quality refrigerated bags are used:

• dense fabric of synthetic fibers - polyester, nylon, are applicable for the outer layer, because they are easy to clean, clean, have high strength;
• PVC - used for the inner layer. Even better - if it has reflective properties.

Important! Interior trim can be made of cheaper polyethylene. But in this case, both insulating and, accordingly, heat and cold-saving properties, will be much lower.

Thickness

Before choosing a refrigerator bag, you need to pay attention not only to the quality of the material in the base, but also its thickness. The minimum from which it is worth to repel is 0.8 cm. More is even better.

Dimensions

Concerning the sizes it is necessary to be guided only by those purposes which you have put, and on own preferences. So, on sale are:

• small containers - their mass reaches a maximum of 400 g, they can put a couple of sandwiches;
• medium-sized thermal bags - they can hold up to 15 kg of products;
• bulky refrigerator bags, in which you will easily transport and 35 kg of food.

Important! Picking up the size, be sure to consider the factor, exactly how you will carry / transport the thermos bottle. If on the car - there are practically no restrictions. But if by hand - it is unlikely you will like to pull a heavy "suitcase" of food. Pleasant impressions uniquely smudge, and the rest will not be this and pleasant.

Completion

The equipment must also be taken with care, as this will depend on the convenience of transportation bags, and layout of products. About the batteries, we have already said above - if they are not in the kit, you must buy it.

What else to pay attention to correctly choose a refrigerator bag:

• If you are looking for a model of the backpack type - the straps must be wide, with soft inserts, adjustable in length.
• If you pay attention to the models of bags with large volume - it is better if they have wheels and a folding handle.
• The built-in lock is an undoubted plus of the model, since even a hermetically sealed cover during transportation can accidentally open. In the end, with a long trip, the products will deteriorate.
• Pockets and compartments for bottles, appliances - very appropriate and practical to use.

Important! Interesting models with a ready-made set of dishes, cutting board, knives - for cutting, opening cans, etc. The dishes can be made of metal or plastic.
