Core Insights - The article discusses the challenges of temperature-sensitive logistics during summer, emphasizing the importance of "coolants" in packaging for fresh produce, pharmaceuticals, and frozen goods [1] Group 1: Types of Coolants - Common coolants include solid carbon dioxide (dry ice), which can maintain temperatures as low as -78.5°C for 12-24 hours, suitable for transporting low-temperature food like meat and seafood [4] - Refrigerated ice packs, also known as 0°C ice packs, maintain temperatures between 2-8°C, typically composed of water and salts [4] - Frozen ice packs can achieve temperatures below 0°C, maintaining conditions between -12°C to -18°C [4] Group 2: Research and Development - A laboratory is conducting experiments to observe temperature changes and dry ice residuals in different foam packaging materials after 24 hours of high-temperature exposure [6] - The project aims to identify better and more cost-effective materials based on the remaining dry ice levels [6] - The lab is also developing a new type of packaging box designed to reduce the amount of ice packs needed, enhancing environmental sustainability [10] Group 3: Usage and Safety - Ordinary ice packs can be reused if they remain sealed and undamaged, but should be cleaned and disinfected before reuse [13] - It is advised not to place dry ice directly in household freezers, as it can rapidly sublimate and increase pressure in sealed spaces, posing safety risks [11]
