Capacity
The volume of the working chamber of the thermal bag. The
larger the volume, the more products can be loaded inside at a time. When choosing according to this parameter, it makes sense to select a model with a margin, because it is not recommended to load products too tightly — this adversely affects the quality of the device. On the other hand, note that the volumetric container and dimensions will have the appropriate ones.
Temperature retention for
The maximum time during which the temperature inside the thermal bag remains unchanged. The low temperature retention time is usually indicated when using the so-called. cold accumulators - pre-cooled blocks with water or other coolant. This parameter is quite conditional, since real time depends on many factors; however, it completely allows you to compare different models of thermal bags with each other.
Fast access
The quick access function is provided to get the necessary product from the thermal bag without opening it completely and thereby not releasing the cold. This is achieved with a Hook-and-loop window at the top, opening which you can quickly take the necessary chilled food or drink. At the same time, Hook-and-loop does not indicate tightness, so this solution in itself can lead to loss of cold.
