What Is a Self Cooling Dry Ice Pack Sheet?
Self cooling dry ice pack sheets are flexible cooling pads that encapsulate compressed solid carbon dioxide (glace carbonique) within protective layers. Dry ice sublimates – meaning it turns directly from a solid to gas – at –78,5 ° C (–109,3 ° F). By combining dry ice with gel or phasechange materials (PCMS) and a protective shell, these sheets deliver ultracold temperatures while controlling the rate of sublimation. Contrairement aux granulés de glace carbonique en vrac, the sheet format is easy to handle, can wrap around product containers and leaves no liquid residue as it vaporizes.
Components of a Self Cooling Dry Ice Pack Sheet
A typical sheet consists of three layers:
| Composant | Description | Importance | Avantage réel |
| Couche de feuille de gel | A flexible, coldretaining material that surrounds the dry ice core | Slows sublimation and spreads the cold evenly | Even temperature distribution prevents hot spots and product damage. |
| Noyau de glace carbonique | The primary cooling element composed of solid CO₂ | Provides ultralow temperatures (–78,5 ° C) and absorbs heat during sublimation | Conserve les vaccins, biologics or frozen foods at required deepfreeze temperatures for extended periods. |
| Coque extérieure de protection | Lightweight and durable covering | Ensures safe handling, prevents moisture ingress and protects contents | Simplifies handling and packaging while keeping the dry ice contained and safe for transport. |
These layers work together to extend the cooling duration, maintenir une température constante, and reduce the risk of direct contact with dry ice. The sheet format also makes it easy for you to pack irregularly shaped items or line the walls of insulated boxes.
How Does a Self Cooling Dry Ice Pack Sheet Work?
Sublimation sur glace carbonique is at the heart of this technology. Quand la glace carbonique (co₂ solide) transitions directly to gas, il absorbe la chaleur de son environnement, keeping the enclosed product cold. In a self cooling sheet, the dry ice core is encapsulated within materials that slow and control sublimation. PCMS, desiccants or gel matrices regulate the gas release so the pack can deliver cooling over 12 à 48 heures ou plus, en fonction de la taille et des conditions environnementales.
The regulated design offers several advantages:
Refroidissement longue durée: Because the sheet slows the sublimation rate, the dry ice lasts longer, providing consistent cooling for longdistance shipments.
Energyfree operation: Unlike mechanical refrigeration, the sheet doesn’t require electricity or batteries.
Moisturefree: As dry ice sublimates directly into CO₂ gas, it leaves no liquid water behind, preventing moisture damage and bacterial growth.
Sécurité et conformité: The encapsulation reduces direct contact with dry ice, making it safer to handle and easier to meet hazardous material regulations.
Why Choose Self Cooling Dry Ice Pack Sheets Over Traditional Packs?
Traditional cold packs include packs de gel, eau (glace) packs and reusable cold packs. Each has pros and cons, mais self cooling dry ice pack sheets provide unique benefits pour les envois surgelés.
| Taper | Plage de température typique | Avantages | Limites |
| Self cooling dry ice sheet | –78,5 ° C; maintains ultracold conditions | Delivers ultralow temperatures for 24–48+ hours; leaves no moisture; energyfree; safe when encapsulated | Requires hazardous material handling; singleuse for most models; overcooling risk if product isn’t meant to freeze. |
| Pack de gel | 0 °C à 8 °C | Flexible; moderate cooling duration; sûr à manipuler | Peut fuir en cas de perforation; limited to chilled (pas gelé) températures; disposal issues. |
| Eau (glace) paquet | 2 °C à 8 °C | Faible coût; élimination facile; non toxique | Masse thermique inférieure; can leak; not suitable for deep freeze. |
