The purpose of ice packs

Usage: Thermal insulation, mainly used for insulated lunch boxes, stewing pots, water bottles, etc. For office workers, it is also a blessing to bring meals at noon and have carefully prepared food to improve their meals. It's getting cold, and the food delivered to the children is still steaming hot, which makes me feel very pleased. Freshness preservation is mainly aimed at fruits that need to be preserved, to prevent harm to fruits caused by high temperatures in hot weather and resulting in nutrient loss. When using, ice bags or ice boxes can be used together with fruits to achieve low-temperature preservation. Cold preservation, targeting chilled beverages, cold drinks, beer, and seafood, can also be used for refrigerated transportation of drugs and vaccines. Its function is also to borrow an ice bag or ice box and place the required low-temperature insulation items in the bag to achieve a continuous low-temperature effect, solving the problem of excessive heating of cold drinks on hot summer days!
