The retention time of cooler bag is affected by which of the following factors

The cold holding time of refrigerated packs is an important performance indicator, which is affected by a variety of factors. The following are the main factors affecting the cold holding time of reefer packs:

1. Material of reefer packs

The material of the reefer pack is the key factor affecting the cold preservation time. Different materials have different heat preservation performance. For example, the use of highly efficient heat preservation materials, such as polyurethane foam, can effectively slow down the rise of internal temperature and prolong the time of cold preservation.

2. External environment temperature

The temperature of the external environment is another important factor that affects the cold preservation time of the refrigerated package. At higher ambient temperatures, the internal temperature of the refrigerated package will be affected by the external heat more quickly, resulting in a shorter retention time. Therefore, when using reefer packs in a high temperature environment, special attention should be paid to choosing reefer packs with good heat preservation performance.

3. Sealability of refrigerated bag

The sealing of the reefer pack also has an important effect on the cooling time. Good sealing can prevent the outside air from entering the inside of the refrigerated bag, reduce the heat transfer, thus prolonging the time of keeping cold. Therefore, when using a reefer pack, make sure the seal is intact to ensure its performance.

4. Nature and quantity of items inside

The nature and quantity of items placed inside the cooler pack will also affect the retention time. For example, some items may release heat and cause the temperature inside the cooler pack to rise; and the greater the number of items, the greater the heat load inside the cooler pack. Therefore, when using a reefer pack, items should be placed reasonably according to the need to prolong the cold holding time.

5. Maintenance and care of the reefer packs

The maintenance and upkeep of the reefer pack will also affect its cooling time. Keeping the outside of the reefer pack clean and dry, avoiding collision and extrusion, can maintain its good heat preservation performance. In addition, regular checking of the insulation performance of the reefer packs to ensure that they are in the best condition is also an important measure to extend the retention time.

In conclusion, the cold preservation time of reefer packs is affected by a variety of factors such as material, external ambient temperature, sealing, the nature and quantity of internal items, as well as maintenance and repair. In order to ensure the performance and use effect of the refrigerated bag, it is necessary to choose the appropriate refrigerated bag according to the actual situation and use and maintain it correctly.
