How Do Gel Packs and Dry Ice Work to Keep Shipments Cold?
Gel packs explained: Gel packs are flexible pouches filled with a non toxic refrigerant gel. Cuando se congele, the gel absorbs heat and slowly releases cold as it thaws. This makes them ideal for maintaining cool temperatures (typically 2–8 °C) for 24–48 hour shipments. Because gel packs do not reach extremely low temperatures, they won’t damage products that are sensitive to freezing, such as fresh produce or certain pharmaceuticals.
Dry ice explained: El hielo seco es la forma sólida de dióxido de carbono. It has a surface temperature of –109.3 °F (–78,5 ºC) and sublimates directly into gas rather than melting into liquid. During sublimation, it absorbs significant heat, maintaining ultra low temperatures for an extended period. Dry ice is widely used to keep frozen goods such as seafood, ice cream and certain vaccines at sub zero temperatures.
Mechanisms of Cooling
Heat absorption and release: Gel packs absorb heat as the gel slowly transitions from solid to liquid. This process happens gradually, providing a stable cooling effect but limited duration. hielo seco, por el contrario, absorbs heat as it sublimates, releasing carbon dioxide gas and providing very low temperatures for a shorter period.
Rango de temperatura: Gel packs maintain a 2–8 °C range, making them perfect for chilled goods and pharmaceuticals. Dry ice keeps products frozen at –78.5 °C and is suited to deep freeze applications.
Handling requirements: Gel packs are non hazardous and safe to handle without special equipment. Dry ice requires insulated gloves and proper ventilation due to the risk of frostbite and CO₂ buildup.
Differences in Use Cases
| Agente refrigerante | Rango de temperatura | Best Applications | Manejo & Regulación | Impacto ambiental |
| Paquetes de gel | 2–8 ° C | Productos frescos, queso, lácteos, productos horneados, chocolates, certain pharmaceuticals | Non toxic, no special regulations, reutilizable | Safe disposal; lower carbon footprint than dry ice |
| Hielo seco | –78,5 ºC | Frozen meats, helado, vaccines and biological samples | Hazardous material; requires gloves and ventilation; subject to shipping regulations | Emits CO₂ during sublimation; high carbon footprint; requires responsible handling and disposal |
| Reusable Cold Packs | Variable | Subscription services, pharma deliveries, B2B shipments; return logistics required | Durable; need cleaning and refreezing infrastructure | Lower long term cost; Reduce el desperdicio |
