[COOLER SHOCK, a cold pack that uses technology developed for medical use] COOLER SHOCK was developed for the medical field of blood transport. It was created by applying the technology. Transporting blood requires maintaining a specified temperature for a long period of time and ensuring that blood components do not change. The package is made of three layers: aluminum, which has excellent thermal conductivity, and polyethylene and nylon, which have excellent rigidity, and is only approximately 0.2 mm thick. This effectively releases the cold temperature inside to the outside. Cooler Shock is designed as an ice pack that maintains -7.8℃ for a long time. The temperature of both ice and cold packs (ice packs) including COOLER SHOCK starts at the temperature of the freezer (0~-12.2℃), and the temperature rises as soon as you take it out of the freezer. Ice quickly heats up, reaches 0°C and then melts, but Cooler Shock is designed to maintain a temperature of -7.8°C, so it can stay cold inside the cooler for a long time. Compared to ice, COOLER SHOCK requires less volume for the same cooling power, reducing the weight of the cooler box and improving space efficiency. Also, when you get home, you can simply put it back in the freezer, which reduces the hassle of cleaning up. [How to use] 1. Pour the necessary tap water for each item into the cooler shock.
