What Is a Nearby Dry Ice Pack and How Does It Differ from Other Coolants?
Dry ice packs are refrigerants made from either dioxyde de carbone solide (Co₂) or super absorbent polymers (SÈVE) that freeze into rigid blankets. They provide ultra low temperatures without leaving a liquid mess. This section explains the definition, benefits and how these packs differ from gel packs and phase change materials.
Definition and Key Benefits
A dry ice pack sheet is a flexible blanket filled with either solid CO₂ pellets or hydrated SAP cells. Quand il est gelé, the sheet wraps around the cargo like a blanket, améliorant la couverture des bords et réduisant les coins chauds. Contrairement aux pellets en vrac, les draps restent en place et minimisent les rejets de CO₂. Traditional gel packs operate at 0–5 °C and melt into water, alors que dry ice sheets maintain temperatures down to −78 °C without leaving water behind. Les avantages clés incluent:
Ultra low temperature without residue – Dry ice sublimates directly to gas, so there’s no water to damage goods.
Flexible coverage – Sheets wrap around product walls for uniform cooling and fewer warm spots.
Durée plus longue – Properly sized sheets can maintain frozen temperatures for 24–72 hours.
Reduced handling risk – Compared with loose pellets, sheets minimise blow off of CO₂ and are easier to remove.
Conformité simplifiée – SAP based sheets avoid hazardous material labels, while true dry ice requires UN 1845 étiquettes.
Comparison with Gel Packs and PCM Blocks
Packs de gel, PCMs and dry ice serve different temperature ranges and durations. The table below compares these options to help you choose the right coolant. Note that dry ice packs operate at much colder temperatures and last longer than gel packs, making them ideal for frozen shipments.
| Type de liquide de refroidissement | Plage de travail | Durée typique | Ce que cela signifie pour vous |
| Feuille de glace carbonique (SÈVE) | Autour 0 °C une fois hydraté; sub zero when using CO₂ cells | 12–48 h pour les envois réfrigérés, 24–72 h for frozen when paired with insulation | Lightweight sheets wrap around odd shapes and are easier to deploy and dispose of than PCMs |
| Briques ou 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) |
| Packs de gel / briques de glace | 0 °C à 5 °C | 8–24 h | Simple et peu coûteux; ideal for chilled goods but not suitable for sub zero shipments |
Use case examples: Pour un kit repas surgelé 36 heures, wrap the sides with a 0.5 inch dry ice sheet and add a top sheet; a regional meal brand used this pattern and kept entrées below −10 °C for 60 heures. For vaccines requiring −20 °C, choose thicker (1 pouce) sheets and add a breathable divider to avoid vial cracking. These examples show how you can tailor sheet thickness and coverage to meet specific hold times.
How Dry Ice Packs Impact Compliance
Parce que la neige carbonique se sublime en gaz CO₂, packages containing it are regulated as hazardous materials. True dry ice sheets (co₂ solide) are classified as Class 9 hazardous material and carry the UN 1845 désignation. This classification triggers labeling, weight limits and training requirements when shipping by air or ground. Hydrated SAP sheets avoid this classification but still need to comply with food contact regulations. When evaluating coolants, consider whether your shipping lane requires hazard labeling and whether training is available for your team.
Where to Buy Dry Ice Packs Near You
Knowing where to purchase dry ice locally helps you avoid shipping delays and reduces cost. Below are proven methods to locate reliable suppliers in your area.
Use Online Search Tools and Directories
Moteurs de recherche et annuaires are your first stop. Enter queries like “dry ice suppliers near me” or “dry ice pack sheets” into your favourite search engine. Many carriers and suppliers maintain store locators that let you filter by product type. Directory websites such as Yellow Pages and Yelp list local suppliers with contact details and hours. Niche platforms like “Dry Ice Supply” or “Industrial Dry Ice” specialise in cold chain products and often identify suppliers that stock sheets alongside pellets.
Check Major Retailers and Gas Companies
Large retailers and industrial gas companies frequently stock dry ice, especially in regions where cold shipping is common. Walmart and Home Depot sometimes sell pre cut sheets in their freezer sections. Gas suppliers such as Airgas and Praxair offer dry ice in various forms—rice pellets, granulés et blocs standard – et permettre la commande en ligne pour un ramassage local. Airgas met l'accent sur le contrôle de la qualité en faisant tourner les stocks dès le premier arrivé., principe du premier sorti; this reduces sublimation losses and ensures freshness.
Visit Pharmacies, Groceries and Ice Manufacturers
Some pharmacies and grocery stores keep small amounts of dry ice for shipping medical samples or frozen products. Les fabricants de glace locaux peuvent couper des blocs, slabs or custom sheets and supply commercial as well as personal needs. Many regional providers highlight dry ice’s versatility for food preservation, voyages de chasse et effets de scène.
Engage Specialty Cold Chain Providers
If you ship regularly or require custom sizes, build a relationship with a dedicated cold chain supplier. These companies can customise sheet sizes, proposer des achats en gros et assurer une disponibilité constante. They often provide training, kits d'isolation et enregistreurs de données. Par exemple, Tempk packages include printed pack out cards and hydration guides so every box is packed consistently. Specialised suppliers can also help you design dual temperature shipments by pairing dry ice sheets with gel packs or PCMs.
Evaluate Supplier Quality and Certifications
When choosing a local vendor, Considérez les facteurs suivants:
Contrôle qualité et traçabilité – Ask if the supplier follows first in, first out rotation and uses traceable containers. Providers such as Airgas rotate stock to ensure product freshness.
Range of products – Look for suppliers that offer different sheet thicknesses and allow custom cutting. A provider with only one size may not fit all your routes.
Certifications et conformité – Verify that the supplier meets food contact regulations and, s'il s'agit de CO₂ solide, détient des certifications relatives aux matières dangereuses. Review training records and hazard communication.
Options de livraison et de ramassage – Assess whether the supplier offers local pickup, livraison programmée ou expédition le jour même. Nearby pickup can cut transit time by 12–24 hours, conserver plus de neige carbonique.
Support client – Choose vendors that provide technical support, emballer les conseils et l'enregistrement des données. Specialists help you optimise packaging and handle emergencies.
Dimensionnement et emballage: Getting the Right Amount
Proper sizing ensures that your payload stays cold without waste. This section explains how to estimate sheet thickness, coverage and quantity for your route.
Select Thickness by Route Duration
Use the following rule of thumb: commencer par 0.5 inch sheets for 24–36 hour lanes, 1.0 inch sheets for 48 heures et 1.25 inch sheets for 72 heures. Thicker sheets hold more dry ice and provide longer duration but increase cost and weight. Many practitioners find that adding extra layers around the sides is more effective than simply increasing thickness.
Match Coverage to Box Dimensions
Line all four walls and the bottom of your insulated shipper to minimise “hot spots” and even out temperature. Adding one or two top panels provides insurance against courier delays. The table below summarises typical coverage patterns and their purpose:
| Couverture | Utilisation typique | Ce que cela signifie pour vous |
| Quatre panneaux muraux | All routes | Minimise les points chauds et uniformise la température |
| Drap supérieur (1–2 panneaux) | 48–72 h lanes | Adds a buffer against delays and heat spikes |
| Feuille inférieure (1 panneau) | All routes | Protège contre les planchers chauds des camions et réduit la fonte |
User Tips for Packing
Follow these practical tips to maximise performance:
Pré-refroidissez tout – Cool the shipper and payload before adding sheets so they don’t waste energy lowering the temperature.
Enrouler puis boucher – Line the sides first, load the product and then place the top sheet. This pattern protects fragile items like vials.
Évitez les lacunes – Use dunnage or foam to eliminate headspace and prevent sheets from shifting.
Essai pilote – Run a 10 box pilot under worst case conditions (vagues de chaleur, longs week-ends) and adjust coverage based on arrival temperatures.
Imprimer des cartes d'emballage – Place step by step instructions inside each kit to reduce training time and ensure consistency. Un hôpital régional combinant une couverture murale complète, une feuille de rappel supérieure et des cartes imprimées et maintenues à −15 °C pendant 72 heures sans excursion.
Exemple de modèle de coût
Assess the cost of a successful delivery by summing sheet cost, coût de la boîte, travail, freight and labels, plus the cost of failures. The model below helps you balance sheet thickness against failure rates:
Successful Delivery Cost = Sheet Cost + Box Cost + Travail + Fret + Étiquettes
+ (Failure Rate × (Product Cost + Réexpédier + Service client))
If a thicker sheet cuts failure rates from 4 % à 1 %, your total delivery cost often drops, freeing budget for marketing or R&D.
Interactive Tool Idea
To engage readers, consider an interactive Calculateur de pack de glace carbonique. Users enter their box dimensions, durée du parcours et température ambiante; the tool suggests sheet thickness and coverage. It could display hold time graphs and cost estimates, encouraging visitors to stay longer on your page and reducing bounce rate. Include a call to action (CTA) to download the calculator or contact a specialist for a customised plan.
Sécurité: Manutention, Stockage, Transport and Disposal
Dry ice’s extreme cold and CO₂ release pose serious hazards. Here’s how to protect people and products while complying with regulations.
Directives de manipulation
Protection contre l'usure – Use insulated gloves and eye protection; avoid direct skin contact to prevent frostbite. The University of Edinburgh warns that even short exposure can cause cold burns and frostbite.
Assurer une aération – Use dry ice only in open or well ventilated areas to prevent CO₂ build up. CO₂ concentrations above 5,000 ppm sur huit heures ou 15,000 ppm terminé 15 minutes dépassent les limites d'exposition sur le lieu de travail.
Never seal it – Do not put dry ice in airtight containers; pressure can build and cause an explosion. FedEx 2025 job aid specifies using fibreboard, caisses en plastique ou en bois avec trous d'aération.
Use tools – Handle pieces with tongs or scoops; avoid leaning into storage bins and keep lids closed when not in use.
Meilleures pratiques de stockage
Choisissez le bon conteneur – Use insulated boxes that allow gas to escape. FedEx prohibits steel drums and recommends polystyrene foam only as inner insulation.
Avoid sealed rooms – Do not store dry ice in freezers, refrigerators or unventilated rooms; keep it in dry, well ventilated spaces away from heat sources.
Rotation des stocks – Follow first in, first out rotation to reduce sublimation and avoid using old sheets; Airgas emphasises this practice for quality control.
Secure access – Store dry ice in a secure area and prevent unauthorised access, especially children or untrained personnel.
Transport Requirements
Étiquetage approprié – Mark packages with “Dry Ice” or “Carbon Dioxide, solide," l'ONU 1845 nombre et poids net. Les étiquettes doivent être au minimum 100 mm on a side..
Emballage ventilé – Ensure boxes vent gas; use holes or vent plugs when using plastic coolers.
Limites des transporteurs – FedEx caps dry ice at 200 kg per package and requires shippers to confirm allowed quantities for air shipments.
Avoid closed vehicles – Do not transport dry ice in passenger compartments; ventilate using outside air if transport is unavoidable.
Élimination: Responsible Practices
Autoriser la sublimation – Let dry ice sublimate in a well ventilated outdoor area. Dry ice sublimates directly from solid to gas at −78 °C, ne laissant aucun liquide.
Avoid sealed bins – Never dispose of dry ice in sealed trash bins, lavabos ou toilettes; l'accumulation de gaz peut provoquer une pression ou une suffocation.
Use disposal facilities – Some hazardous waste facilities accept dry ice; call ahead to verify.
Hire professionals for large volumes – For large quantities or urgent disposal, consider hiring a disposal service that can neutralise dry ice safely.
