Que sont les briques de glace carbonique et les packs de glace carbonique, et pourquoi sont-ils importants?
Dry ice bricks and dry ice packs are both made from solid carbon dioxide (Co₂) que Limères soudantes directly into gas without melting. This means no water residue, ce qui les rend idéaux pour expédier des aliments surgelés, produits pharmaceutiques et échantillons de laboratoire. Dry ice bricks are rigid blocks that sublimate slowly and provide longlasting cooling, alors que dry ice packs are flexible sheets, pellets ou tranches designed for faster cooling and easier placement. Because dry ice’s temperature is approximately −78,5 ° C (−109 ° F), it offers three times the cooling efficiency of water ice. Choosing the right form keeps your products safe, reduces waste and helps you comply with shipping regulations.
Formulaires, Sizes and Cooling Mechanisms
Dry ice comes in different forms to match various logistics needs:
| Formulaire | Taille typique | Taux de sublimation | Ce que cela signifie pour vous |
| Blocs | Grand, dense slabs | Lent (48–72 h in insulated boxes) | Ideal for longdistance shipments; lower surface area means heat is absorbed slowly. |
| Boulettes (riz) | Small cylinders (~1/8–3/8 in.) | Rapide (12–24 h) | Provide precise cooling and fill gaps; often used in laboratories and dryice blasting. |
| Slices/Nuggets | Mediumsized pieces | Modéré | Fit tight spaces; useful for small packages or field kits. |
| Premade packs | Enclosed pellets in vented packaging | Variable | Designed to release CO₂ gas slowly around products, keeping them cold without direct contact. |
Briques de glace carbonique are heavy and cumbersome to lift, but they maintain temperatures longer than pellets. Packs de glace sec are easier to handle and can be arranged around irregular products, but they may need replacement sooner.
Astuces et conseils pratiques d'utilisation
Pour les longs trajets et les charges lourdes: Use dry ice bricks or large industrial packs. Their slow sublimation keeps cargo frozen for days.
For precision cooling or small packaging: Utilisez des granulés ou des tranches pour remplir les espaces et assurer un refroidissement uniforme.
Combinez les formulaires si nécessaire: Mixed shipments can combine bricks for frozen goods and gel packs for chilled items.
Cas réel: A seafood exporter replaced water ice with small dryice slices. By venting insulated boxes and placing packs correctly, l'entreprise reduced shipment weight by 30 % et gardait les filets de poisson congelés pendant 48 heures sans fuite.
Choosing Between Dry Ice Bricks and Dry Ice Packs: Facteurs à considérer
Selecting the right cooling agent depends on shipment duration, product requirements and customer experience. Briques de glace carbonique excel for long durations (48+ heures) et charges lourdes; they maintain ultracold temperatures below −70 °C and are essential for vaccines, frozen meat or biologic samples. Packs de glace sec work well for shorter trips or smaller packages and are easier for customers to handle. Gel packs or phasechange materials may be preferable when goods need to remain chilled rather than frozen.
Exigences de température du produit
Different products have distinct temperature needs:
Marchandises surgelées (glace, fruit de mer, vaccins): nécessitent des conditions ultra froides; dry ice sublimates at −78.5 °C ensuring these items stay frozen.
Marchandises refroidies (chocolat, medicines requiring 2–8 °C): gel packs or phasechange materials are more suitable because they maintain temperatures above freezing.
Durée et distance d'expédition
Longdistance shipments or routes through warm climates favour dryice bricks, which last 48–72 hours. Local deliveries or sameday shipments can rely on gel packs or smaller dryice packs. Equal weight of dry ice and payload can keep items frozen for up to 48 heures, et 1.5× the weight may be needed for 72 heures.
Manipulation et conformité réglementaire
La glace carbonique est classée comme Et 1845 sous des matières dangereuses par le Association internationale des transports aériens (Iata) Et les États-Unis. Ministère des Transports (POINT). Expéditions dépassant 5 lbs require labeling with “Dry Ice (Dioxyde de carbone solide) UN 1845” and weight declaration. Gel packs are not regulated and therefore easier for customers to handle.
Coût et durabilité
La glace carbonique est périssable et doit être réapprovisionnée pour chaque expédition. Gel packs are reusable and lower cost, but they cannot maintain ultracold temperatures. Packs de glace carbonique réutilisables, emerging in 2025, can be refilled with solid CO₂ multiple times and help businesses économiser jusqu'à 20 % on cooling costs while reducing plastic waste.
Customer Experience
Customers unfamiliar with dry ice may worry about frostbite or disposal. Provide clear instructions and protective equipment when sending dryice shipments. For meal kits or consumer deliveries, consider a hybrid approach that uses dry ice for frozen components and gel packs for fresh produce.

Calculer la quantité correcte de glace carbonique
Règle générale: Utiliser 1–2 lbs of dry ice for every 3–4 lbs of product.
24heure de vol: 15 lbs of dry ice can maintain −70 °C conditions for a 24hour shipment.
Rapports de poids: Half the weight of the payload in dry ice covers overnight shipments; equal weight is needed for 48 heures, et 1.5× poids may be required for 72 heures.
Packing and Insulation Tips
Préconditionner les conteneurs: Refroidissez les boîtes avant d'ajouter de la neige carbonique pour ralentir la sublimation.
Couper correctement: Place dry ice on top of the products so cold air sinks; use cardboard or cushioning to protect goods sensitive to extreme cold.
Emballage de ventilation: Ne jamais fermer hermétiquement les contenants; use styrofoam lined with cardboard to allow CO₂ gas to escape.
Minimiser l'espace vide: Combler les espaces avec des matériaux isolants (mousse, boulettes) pour éviter les poches chaudes.
Use robust outer packaging: Corrugated cardboard or heavyduty plastic boxes provide strength; évitez les fûts en acier ou les récipients en plastique scellés.
Safety Precautions and Regulatory Considerations
Portez un équipement de protection: Utilisez des gants isolés, goggles and closedtoe shoes to avoid frostbite.
Assurer la ventilation: Une livre de neige carbonique libère environ 250 litres de gaz CO₂; store and handle in wellventilated areas.
Paquets d'étiquettes: Marquez les expéditions avec « Glace sèche (Dioxyde de carbone solide) UN 1845” and include net weight to comply with DOT/IATA rules.
Évitez les matériaux incompatibles: Métaux, plastics or glass can crack at extreme cold; use containers rated for dry ice.
Former les gestionnaires et les clients: Provide instructions for safe use and disposal; untrained staff may mishandle dry ice and risk frostbite or asphyxiation.
Élimination: Laisser la neige carbonique se sublimer dans un espace ouvert; never dump it in sinks or drains.
Cas réel: A biotech lab packed 15 livres de glace carbonique in prechilled containers with ventilation holes for a 24heure de vol, réalisation −70 °C throughout transit without pressure buildup.
Erreurs courantes pour éviter
Sealing containers completely – traps CO₂ and can cause explosions.
Underestimating dryice quantity – leads to thawing; adjust for ambient temperature and travel time.
Contacting water – speeds up sublimation; keep dry ice dry.
Sauter une formation – untrained staff may neglect ventilation and protective gear.
Manipulation sûre, Packaging and Disposal
In addition to the guidelines above, ensure your operation meets regulatory standards:
Classement réglementaire: La glace sèche est une classe 9 matières dangereuses (Et 1845); shipments require labeling and documentation.
Air transport restrictions: L'IATA limite la glace carbonique à 200 kg par colis à bord des avions de passagers.
Postal regulations: Les États-Unis. Postal Service allows dryice shipments domestically but restricts them to 5 livres par paquet, whereas FedEx or UPS allow larger shipments with appropriate documentation.
Educate both staff and customers about safe handling. Provide printed guides inside packages that explain how to handle and dispose of dry ice responsibly. Encourage recipients to let dry ice sublimate outdoors or in ventilated areas.
Comment les packs de glace carbonique réutilisables et la technologie intelligente se transforment 2025 Logistique de la chaîne du froid

Au niveau macro, logistics providers operate control towers where artificial intelligence analyses temperature data, predicts potential excursions and recommends interventions. This proactive approach reduces spoilage and improves compliance.
Hybrid Systems and Improved Insulation
Hybrid cold chain systems combine dry ice with matériaux à changement de phase (PCMS) ou packs de gel. Les PCM absorbent et relâchent la chaleur à des températures spécifiques (par exemple. 2–8 °C ou −20 °C) et sont réutilisables. La glace carbonique offre des conditions ultra froides, while PCMs maintain chilled zones. Hybrid packaging allows multitemperature shipments, ideal for mixed cargo like frozen meat and fresh vegetables. Panneaux d'isolation sous vide (Vips) also improve cold retention, allowing companies to use less dry ice while maintaining required temperatures.
Market Dynamics and Sustainability
Demand for dry ice is growing across sectors, but CO₂ supply is constrained. The global dry ice market is projected to croître à partir de l'USD 1.66 milliards en 2025 en USD 2.73 milliards 2032, while demand for cold chain packaging refrigerants will reach USD 2.92 milliards 2032.
