At the dawn of the 21st century, keeping food fresh is as important as it was a hundred years ago.
This question is especially relevant for lovers of long-distance travel. How do you keep food he althy so you can snack on it on the go?
At the end of the last century, a way out was found. A special isothermal cooler bag appeared. What is this device? And how does it function?
Such a bag (isothermal container) is a must if you want your food to stay fresh for as long as possible. Most often it is used for cooling or storing frozen semi-finished products. But there are times when it is used to keep food hot. Popularly, such models are called a cooler bag, but this is not entirely true. Any refrigerator has a cooling device. The isothermal bag is deprived of it. It performs its functions due to the cold accumulator. Over time, the temperature inside becomes the same as the ambient temperature. How long is the bagwill keep food frozen depends on its specifications. As a general rule, larger containers keep cold better.
All the useful properties of the thermal bag depend on the cold accumulator.
This is a plastic briquette filled with a special saline solution. The more such devices in the container, the longer it keeps a low temperature. Without a battery, an insulated bag can keep the cold up to 3 hours, with it, this time can be significantly increased.
What are the advantages of this model?
- Insulated bag can maintain both cold and hot temperatures.
- Compact and portable are two of the things that make this item so popular.
- Great design, many bags look very sophisticated and presentable.
- Reliable protection. Various lightnings, peaks help to keep products safe and sound. Security zips keep them secure inside, preventing accidental opening of the bag.
- Internal convenience. Usually there are several compartments inside the bag. For example, for cans or bottles. And some of them also have a set of dishes in the kit. All this helps to arrange products easily and conveniently.
And, perhaps, the most basic question: "What to look for when choosing such a model?"
First of all, if you are interested in an insulated bag, decide on the volume. Their capacity is different - from 5 to 30 liters. For normala medium-sized container will suffice for a family.
The second important factor is the material from which the insulated bag is made. Usually nylon, plastic, polyester are used for this purpose. They are durable and easy to clean. It is desirable that the inside is a PVC material with reflective properties.
Next, pay attention to the convenience of transporting the bag. She must have special handles. In case you settled on a fairly roomy model, the bag should be equipped with roller wheels. Otherwise, it may be difficult to carry it, and even filled with a large number of products.
Immediately in the store, check the reliability and safety of carrying. The main thing is that the bag does not open spontaneously. There must be special security locks for this.
If you carefully examined the product and everything suits you in it, feel free to buy a thermal bag. It will serve you faithfully for many years.
