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.
External compartment
An additional compartment on the outside of the bag is designed for convenient storage of small items such as a phone, keys, cards, utensils, napkins, or cutlery. External compartments usually have a zipper, Velcro, or clasp, allowing you to quickly and safely access items without opening the main compartment, where food or drinks are stored. These pockets can be made from the same thermal insulation material as the main compartment or from a less insulating material, depending on the user's needs.
Carrying handle (in one hand)
A convenient element designed to facilitate the transportation of a bag or container with products, drinks, or frozen goods. The handle can be made of durable materials such as nylon, leather, or rubber, and often comes with soft pads for comfort during extended carrying (for boxes, plastic handles are more relevant). It is worth noting that it refers to a single handle on the top of the body, which allows you to carry a thermal bag or container in one hand.
