The proper way to use a cooler bag

A cooler bag is a portable device used to keep items that need to be refrigerated or frozen, and is widely used in food, pharmaceuticals, cosmetics, and other fields. In order to ensure that the items inside the cooler bag remain at the proper temperature, it is vital that the cooler bag is used correctly. Below are the proper ways to use a cooler bag:

1. Pre-understanding of the performance of the reefer pack: Before use, understand the capacity, insulation performance, the use of temperature range and other information, in order to choose the right reefer pack to meet specific needs.
2. Item Preparation: Organize the items to be refrigerated in advance to ensure that they adapt to the capacity of the cooler bag, and avoid excessive accumulation of items resulting in uneven cooling.
3. Pre-treatment of items: Certain items need to be pre-treated before placing them in the cooler, such as drying them out and packing them so that they do not become frosty or damp during the refrigeration process.
4. Pre-use inspection: Ensure that the inside and outside of the reefer pack is clean and free from damage or leakage. Check the sealing performance of the cooler bag to ensure that the internal temperature can be well maintained.
5. Placement of ice packs or coolants: Place appropriate amount of ice packs or coolants according to the requirements of the cooler bag. Make sure they are evenly distributed inside the bag to provide even cooling.
6. Place items: Place items to be cooled into the cooler bag, distributing them as evenly as possible to ensure optimal cooling.
7. Close and Seal: Close the zipper or lid of the cooler bag and make sure it is well sealed to prevent outside heat from entering.
8. Storage environment: Store the cooler bag in a cool, dry and ventilated place, avoiding direct sunlight and hot environments.
9. Regular Inspection: Check the temperature inside the cooler bag and the condition of the items regularly during use to ensure they remain within the proper temperature range.
10. CAUTION: Avoid exposing the cooler bag to temperature extremes such as high, low or humid temperatures. Avoid placing flammable, explosive or corrosive items inside the cooler bag.

Proper use of a cooler bag ensures that items are kept at the proper temperature during transportation and storage, extending their shelf life and maintaining good quality. Therefore, following the steps outlined above for proper use of a cooler bag is essential to protect items and ensure safety.
