What Are Nearby Dry Ice Packs and Why Do They Matter?
Réponse rapide
Dry ice packs are flexible sheets or blocks filled with either solid carbon dioxide (Co₂) pellets or superabsorbent polymer (SÈVE) cells that freeze into rigid, subzero blankets. Contrairement aux packs de gel, which operate at 0 °C à 5 °C, dry ice packs maintain temperatures as low as –78 °C without producing liquid water. They keep vaccines, frozen meals and biological samples cold for 24–72 heures, and because they sublimate directly from solid to gas, there’s no messy meltwater to damage goods. This ultralow cooling capability is critical for shipping biologics or frozen foods during long transits when local supplies are limited.
Explication détaillée
When you need to send something frozen across town or across the country, you have a few cooling options. Packs de glace sec are essentially insulating blankets containing either compressed CO₂ or SAP cells. Carbon dioxide sublimates at –78,5 ° C, so these packs act like portable freezers. SAPbased packs use a polymer that freezes around 0 °C and are safer for domestic transport because they avoid the hazardous material classification. Traditional gel packs maintain refrigerator temperatures (0 °C à 5 °C) and melt into liquid, alors que matériau à changement de phase (PCM) briques can be engineered for temperatures between –25 °C and +25 °C.
Dans 2025, demand for dry ice remains strong because vaccines, biologics and frozen meal kits require extremely cold conditions. Mondial dryice consumption is rising roughly 5 % annuellement, mais l'offre de CO₂ ne fait qu'augmenter 0.5 %, entraînant des pénuries et des flambées de prix. Pour atténuer cela, manufacturers are establishing localized CO₂ capture and reuse at food plants, and some shippers are blending dry ice with PCM and improved insulation to stretch each pound of dry ice further. En même temps, more businesses are exploring CO₂ biosourcé sources. During bioethanol fermentation, highpurity CO₂ is released as a byproduct; capturing and purifying this gas creates a lowercarbon supply for dry ice.
By understanding how dry ice packs work and how they differ from gel packs and PCMs, you can select the right coolant for your product, shipping distance and regulatory requirements. The sections below provide practical comparisons and decision tools.
Choosing Between Dry Ice Packs, Gel Packs and PCM
Why the Right Coolant Matters
Selecting the appropriate refrigerant is like choosing the right jacket for a winter trip: a light hoodie won’t keep you warm in a blizzard. Dry ice packs excel at ultracold temperatures and long durations but require hazard labels; gel packs are inexpensive and safe but only keep items chilled; PCM bricks offer customizable temperature profiles but cost more and need special preconditioning. Use the comparison table below as a quick reference.
| Type de liquide de refroidissement | Plage de température de fonctionnement | Durée typique | Ce que cela signifie pour vous |
| Feuille de glace carbonique (SÈVE) | Autour 0 °C une fois hydraté; subzero when CO₂ cells are used | 12–48 h pour les envois réfrigérés; 24–72 h for frozen goods | Lightweight sheets conform to odd shapes and are easy to dispose of; aucun résidu liquide; some formats avoid hazardous material labels |
| Briques/tuiles PCM | –25 °C à +25 °C selon formulation | 24–96 h | Assurer un contrôle strict de la température pour les audits; coût initial plus élevé; nécessitent un préconditionnement (congélation ou chauffage); ideal when regulatory audits require specific temperature ranges |
| Packs de gel / briques de glace | 0 °C à 5 °C | 8–24 h | Simple et peu coûteux; best for chilled goods like produce or beverages but not suitable for frozen shipments |
Astuces et conseils pratiques
Pour les plats surgelés (24–36 heures): Utiliser un 0.5 inch dry ice sheet that wraps around the sides and add a top sheet to maintain –10 °C or lower. A regional meal kit brand used this pattern and kept entrées below –10 °C for 60 heures.
Pour les vaccins nécessitant –20 °C: Optez pour plus d'épaisseur (1 pouce) dry ice sheets and insert a breathable divider to prevent vial cracking.
Pour les articles réfrigérés (8–12 heures): Les packs de gel sont rentables et évitent les étiquetages dangereux. Pair them with insulated liners for short local deliveries.
For temperature audits or mixed loads: Consider PCM bricks with target ranges (Par exemple, –25 °C or +15 °C) to keep different products within specified temperature bands.
Cas réel: Un distributeur mondial de vaccins a augmenté l'efficacité de ses livraisons de 36 heures pour 72 heures by pairing insulated containers with dry ice packs, extending vaccine potency during transit.

Safety Guidelines for Handling, Shipping and Disposing of Dry Ice
Réponse rapide
La glace carbonique est classée dans une classe 9 matières dangereuses because sublimation releases CO₂ gas, which can build up pressure and displace oxygen. Portez toujours des gants isolants et des lunettes de protection lorsque vous manipulez de la neige carbonique, and store it in insulated containers that allow gas to escape. Never seal dry ice in an airtight container—expanding gas can cause explosions. Pour expédition, follow carrier rules such as FedEx, UPS or USPS; label packages with “UN 1845” and the net weight of dry ice, use triple packing (primary leakproof container, secondary container with absorbent material, boîte isotherme) and leave vents for gas release.
Sécurité de manipulation et de stockage
Protect Yourself: La glace carbonique est extrêmement froide (–78,5 ° C) and can cause frostbite within seconds. Utilisez toujours des gants isolés, tongs and eye protection.
Ventiler: Sublimating CO₂ displaces oxygen. Work in a wellventilated area to prevent suffocation. Avoid storing dry ice in confined spaces or vehicles.
Utiliser des conteneurs isolés, Not Airtight Ones: Select polystyrene or polyurethane coolers that allow gas to escape. Faire pas store dry ice in sealed jars or metal cans. Pressure buildup can cause explosions.
Avoid Metal Tools: Direct contact with metal can cause equipment to freeze and break.
Dispose Properly: Let remaining dry ice sublimate in a wellventilated area; never put it in sinks or toilets, as it can freeze pipes or explode when contacting water.
Packaging and Shipping Requirements
Classification des dangers et étiquetage: Solid CO₂ is labeled “Dry Ice” or “Carbon Dioxide, Solid” and designated UN 1845. You must display a Class 9 diamond and note the net weight of dry ice on the package
Triple emballage: Utiliser un leakproof primary container for the product, un secondary container with absorbent material, et un insulated outer box containing the dry ice. Secure the contents so they don’t shift. Leave openings for gas release—never fully seal the insulated box with tape.
Carrier Rules: FedEx, UPS and USPS have specific dryice rules. FedEx and UPS allow domestic and international dryice shipments with proper labeling and weight declarations. USPS permits domestic shipments but limits dry ice to 5 lbs for air transport and requires labels. Choose expedited services to reduce transit time.
Certification: To ship dry ice by air, shippers must be certified and trained in hazardous material handling. Certification is valid for two years and must be renewed.
Conseil
Proper labeling saves lives: A mislabeled package containing dry ice once caused an airplane cargo hold to fill with CO₂, triggering oxygen masks and emergency procedures. Always label your package with UN 1845 and the net weight to ensure carriers handle it correctly and mitigate risks.
