Why Are Cheap Dry Ice Packs Ideal for Medicine Transport?
Réponse directe: Cheap dry ice packs provide ultra cold temperatures and leave no liquid residue, making them ideal for keeping medicines frozen. Glace sèche, ou dioxyde de carbone solide, stays at –78,5 ° C et se sublime directement en gaz. This process absorbs heat and keeps pharmaceuticals and vaccines frozen without water or melt damage. For vaccine shipments—like those requiring –70 °C—10 mm dry ice nuggets ensure correct storage and prevent temperature excursions.
Explication plus approfondie: De nombreux médicaments, comme les produits biologiques, gene therapies and some vaccines, must remain frozen throughout their journey. When dry ice packs sublimate, they draw heat away from the shipment, creating a cold blanket that can last 24–72 heures. Unlike ice or gel packs that melt into water, la glace carbonique ne laisse aucun résidu, preventing moisture contamination or label damage. This is especially crucial for diagnostic kits and biologic samples that cannot get wet. Dry ice packs deliver consistent ultra low temperatures (en dessous de –70 °C) for sensitive payloads, while gel or water packs only maintain 2–8 ° C. Because dry ice is inexpensive on a per shipment basis and widely available, it’s a cost effective way to maintain the integrity of high value pharmaceuticals.
Sublimation and Cooling Power
Dry ice cooling power comes from sublimation—the direct transition from solid to gas. When CO₂ molecules absorb heat from the environment, they release cold carbon dioxide gas, creating an ultra cold environment. Each pound of dry ice can provide roughly three times the refrigeration power of regular ice, and properly insulated parcels can stay cold for three to five days. Unlike gel packs that melt and leak, sublimation leaves behind no liquid. Because of this efficiency, less dry ice is often needed to achieve the same cooling duration, keeping shipping weight and cost down.
| Méthode de refroidissement | Plage de température | Durée de refroidissement | Ce que cela signifie pour vous |
| Packs de glace sec | Autour de –78,5 °C (–109,3 ° F) | 24–72 heures, jusqu'à 5 days with good insulation | Idéal pour les vaccins congelés, biologics and blood products; keeps them below –70 °C without meltwater |
| Packs de gel | 2–8 ° C (refrigerated range) | 24–48 heures | Suitable for chilled medicines and diagnostics; cannot maintain deep freeze temperatures |
| Packs d'eau (Glace) | 2–8 ° C | Expéditions courtes | Low cost but risk of leakage or overcooling; not appropriate for frozen materials |
| Packs PCM | –20 °C à +2 °C | Jusqu'à 96 heures | Reusable and stable; good for vaccines and biologics requiring 2–8 °C; not cold enough for ultra frozen goods |
Practical Tips for Selecting Dry Ice Packs
Determine Temperature Requirements: Use dry ice for anything needing below –70 °C (Par exemple, mRNA vaccines or gene therapies). For medicines that only require refrigeration, gel or PCM may suffice.
Match Pack Size to Transit Time: Chaque 5–10 livres de glace carbonique sublimera chaque 24 heures. Estimate transit time plus an extra day for delays to determine the required quantity.
Choose Nugget vs. Slab vs. Feuille: Nuggets provide quick cooling and fill space more evenly; slabs offer longer hold times; scored sheets are flexible for irregular loads. Select based on payload shape and duration.
Assurer une bonne ventilation: Dry ice sublimation can build pressure. L'emballage doit permettre au gaz de s'échapper (Jamais hermétique).
Real world Case: During COVID 19 vaccine distribution, logistics companies used 10 mm dry ice nuggets to maintain –70 °C shipping temperatures. This form fit around vials, delivered consistent cold, and left no water residue, allowing vaccines to arrive potent and contamination free.
What Factors Affect the Cost of Dry Ice Packs in Medical Shipping?
