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 (الثلج الجاف) within protective layers. Dry ice sublimates – meaning it turns directly from a solid to gas – at -78.5 درجة مئوية (–109.3 °F). By combining dry ice with gel or phase change materials (PCMS) and a protective shell, these sheets deliver ultra cold temperatures while controlling the rate of sublimation. Unlike loose dry ice pellets, 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:
| Component | وصف | Significance | Real World Benefit |
| Gel sheet layer | A flexible, cold retaining material that surrounds the dry ice core | Slows sublimation and spreads the cold evenly | Even temperature distribution prevents hot spots and product damage. |
| Dry ice core | The primary cooling element composed of solid CO₂ | Provides ultra low temperatures (-78.5 درجة مئوية) and absorbs heat during sublimation | Keeps vaccines, biologics or frozen foods at required deep freeze temperatures for extended periods. |
| Protective outer shell | 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, maintain a consistent temperature, 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?
Dry ice sublimation is at the heart of this technology. When dry ice (CO₂ الصلبة) transitions directly to gas, فهو يمتص الحرارة من البيئة المحيطة به, 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 ل 48 ساعات أو أكثر, depending on size and environmental conditions.
The regulated design offers several advantages:
Long lasting cooling: Because the sheet slows the sublimation rate, the dry ice lasts longer, providing consistent cooling for long distance shipments.
Energy free operation: Unlike mechanical refrigeration, the sheet doesn’t require electricity or batteries.
Moisture free: As dry ice sublimates directly into CO₂ gas, it leaves no liquid water behind, preventing moisture damage and bacterial growth.
Safety and compliance: 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 حزم هلام, ماء (الجليد) packs and reusable cold packs. Each has pros and cons, لكن self cooling dry ice pack sheets provide unique benefits for deep freeze shipments.
