What Is a Temperature Control Dry Ice Pack and Why Does It Matter?
Temperature control dry ice packs are insulated containers filled with dry ice that keep your payload at or below −10 °C during transit. على عكس الجليد العادي, الجليد الجاف لا يذوب في الماء; it sublimates directly from solid to gas, absorbing heat without leaving moisture. The resulting cold sink dramatically slows down warming, making these packs ideal for frozen foods, medical samples and biologics that must remain deeply frozen. Think of the pack as a portable freezer: the insulation acts like a thermos, while the dry ice serves as the engine.
How Dry Ice Packs Compare to Gel and PCM Solutions
When you look at alternatives such as gel packs or phase change materials (PCMS), differences become clear. Gel packs operate between 0 °C and +8 °C and are great for chilled shipments, but they cannot maintain deep freeze temperatures and may thaw quickly during long delays. PCMs absorb heat at specific temperature ranges (على سبيل المثال, 2–8 °C or −20 °C) وقابلة لإعادة الاستخدام, but they do not achieve the ultra cold environment that dry ice delivers. Dry ice sublimates at −78.5 °C, providing an ultra cold buffer that outperforms gel packs in holding frozen goods for 24–96 hours. A hybrid approach—combining small dry ice blocks with gel or PCM packs—can stabilize temperature curves for shoulder seasons when over freezing is a concern.

How to Use Temperature Control Dry Ice Packs Correctly
Proper packing and handling make the difference between a perfect delivery and a spoiled shipment. Follow these steps to ensure your dry ice pack works effectively and remains compliant:
Calculate required quantity: Estimate dry ice amount based on box volume, insulation quality and transit duration. A rough guideline is 5– 10 رطل من الثلج الجاف لكل 10 L of volume per 24 ساعات, with warm routes requiring more and cold routes requiring less. Use a simple lane based calculator to refine the estimate.
Pack in layers: Place products in the insulated box and top load the dry ice. الهواء البارد يغرق بشكل طبيعي, ضمان التبريد المتساوي. Wrap delicate items to prevent frost damage and shrink void space to slow warm up.
تنفيس الحاوية: Dry ice sublimation produces CO₂ gas that must escape. Never seal the box completely; use a vented lid or leave a small gap.
التسمية والوثيقة: Clearly mark packages with “Dry Ice, UN 1845” and indicate net weight. للشحنات الجوية, follow IATA Packing Instruction 904 and ensure the declaration is included if other hazardous materials are present.
Protect handlers: Provide gloves and safety instructions to anyone handling dry ice. Avoid direct skin contact and store unused dry ice in a ventilated area; never place dry ice in a sealed freezer or cooler.
Include a receiver card: Add a simple card instructing receivers to open the box in a ventilated area and avoid touching dry ice directly.
A Quick Self Check
Before sending your shipment, run through this five point readiness check:
Dry ice quantity and box liters recorded
Vented lid or vent holes verified
Net CO₂ weight printed on the shipping label
