What Is an Eco Friendly Dry Ice Pack Sheet and Why Does It Matter?
Réponse directe et avantages clés
Un eco friendly dry ice pack sheet est un flexible blanket of solid CO₂ encased in a film biodégradable. Each cell within the sheet holds dry ice that sublimates at about −78,5 ° C, absorbing heat without leaving moisture and keeping goods frozen for 24–72 heures. The biodegradable outer layer—usually paper, cellulose or plant based polymers—breaks down naturally after use and eliminates plastic waste. Parce que la fiche est conforme à votre envoi, il maximise l'efficacité du contact et du refroidissement tout en réduisant l'espace vide.
Explication élargie
Dry ice sheets act like mini cold batteries. The dry ice inside sublimates directly from solid to gas, absorbing considerable heat. One pound of dry ice produces 8.3 cu ft of CO₂ gas; this means your packaging must allow gas to vent to prevent pressure build up. Compared with traditional gel packs that melt and release water, a dry ice sheet leaves no liquid residue, keeping products dry. The outer film can be made from papier, cellulose ou polymères compostables, which decompose naturally. Because dry ice sublimates into a gas, there is no water consumption and no solid waste.
Dans la logistique de la chaîne du froid, these sheets excel for shipments requiring températures ultra froides (–20 °C à –70 °C). Unlike traditional dry ice pellets that may require hazardous material documentation, flexible sheets are often classified as non dangereux, simplifier la conformité. They activate immediately when flexed and provide consistent cold without the messy sublimation issues of loose dry ice. Combined with insulated containers and vented packaging, they maintain product integrity for overnight deliveries or long haul transport.

| Film extérieur | Papier, cellulose or PLA/PBAT bioplastics | Encases dry ice cells and protects contents | Eliminates plastic waste; film biodegrades naturally |
| Dry ice cells | Co₂ solide | Sublimates at –78.5 °C, absorption de la chaleur | Fournit du froid ultra, refroidissement sans humidité pendant 24 à 72 h |
| Caractéristiques de ventilation | Perforations ou canaux respirants | Permettre au gaz CO₂ de s'échapper en toute sécurité | Prevents pressure build up and ensures regulatory compliance |
Astuces et conseils pratiques
Choose the right sheet thickness: Thicker sheets hold more dry ice and sustain ultra low temperatures longer. Plan according to journey duration and product sensitivity.
Pre chill goods and container: Cooling items and the box reduces dry ice consumption and extends cooling duration.
Vent your packaging: Leave small gaps or use vented lids so CO₂ gas can escape safely. Sealed containers can explode when pressure builds up.
Portez un équipement de protection: La glace carbonique peut provoquer des engelures. Always handle sheets with insulated gloves and goggles.
Utiliser des conteneurs isothermes: Dry ice sublimates faster in warm environments; insulation slows heat transfer.
Cas du monde réel: A pharmaceutical distributor hydrated and froze a biodegradable dry ice pack sheet, then layered it around vaccine vials. Venting the cooler and using gloves, they maintained −70 °C for 48 heures without temperature excursions—and eliminated plastic waste.
Why Choose Eco Friendly Dry Ice Pack Sheets?
Sustainability and Environmental Benefits
Sustainability in cold chain logistics is advancing through sources de CO₂ renouvelables, matériaux d'emballage respectueux de l'environnement et circular programs. Traditional dry ice is made from captured industrial CO₂ emissions, but many producers now source CO₂ from biogas plants, réduire la dépendance aux combustibles fossiles. Packaging supplies are increasingly derived from matériaux recyclables ou biodégradables, and take back programs refurbish used sheets.
UN 2018 study found that the U.S. généré 80 000 tons of expanded polystyrene foam conditionnement, mais moins que 1 % a été recyclé. Consumer attitudes are shifting: 43 % of consumers consider packaging sustainability lors de la prise de décisions d'achat. Companies adopting eco friendly dry ice sheets and biodegradable liners have reported significant benefits. A pharmaceutical firm reduced packaging waste by 60 % et les coûts par 40 % after switching to sustainable dry ice solutions. Another logistics company observed a 20 % réduction des coûts de refroidissement within six months of transitioning to reusable dry ice packs.
Bioplastics like acide polylactique (PLA) et polybutylene adipate terephthalate (PBAT) are effective replacements for conventional plastic films. These bioplastics can be recycled or composted to become soil conditioners. Their robust mechanical properties withstand ultra cold temperatures, making them ideal for dry ice packaging. En revanche, petroleum based plastics contribute to landfill waste and require energy intensive recycling. By choosing compostable films, your organization can lower its carbon footprint and appeal to eco conscious customers.

How to Use Eco Friendly Dry Ice Pack Sheets Safely
Proper handling ensures optimal performance and protects people. Follow this step by step process to activate, pack and dispose of your dry ice sheets.
Planifiez votre expédition: Déterminer la plage de température et la durée requises. For shipments needing sub zero conditions for more than 24 heures, sélectionner une feuille avec une épaisseur et une quantité adéquates.
Hydrater et congeler: Activate the sheet by immersing it in warm water and massaging the cells until fully expanded. Freeze the sheet flat for at least 24 heures pour atteindre la température la plus basse possible.
Préparez le récipient: Pré-refroidir le récipient et les produits. Line the bottom with insulation (foam or paper liners) to reduce heat infiltration.
Emballez stratégiquement: Position the sheet around or above goods; avoid direct contact with biologics to prevent freezing damage. Fill voids with biodegradable cushioning.
Ventilation et étiquette: Ensure ventilation holes or breathable lids allow CO₂ gas to escape. Étiqueter les emballages « Glace sèche » et indiquer leur poids pour assurer la conformité réglementaire.
Surveiller la température: Utilisez des enregistreurs de température ou des capteurs intelligents pour suivre les conditions pendant le transport. Data helps fine tune future shipments.
Éliminer ou réutiliser de manière responsable: Allow remaining dry ice to sublimate in a ventilated area; compost or recycle the biodegradable film according to local guidelines. Inspect reusable sheets for damage and sanitize before the next use.
Safety Guidelines and Handling Tips
La glace carbonique est extrêmement froide, so treat it with respect. According to OSHA safety guidelines, dry ice is frozen carbon dioxide that does not melt into a liquid but changes directly into gas. The temperature of dry ice is –78 ° C, so touching it bare handed can cause frostbite. Toujours porter protective gloves and goggles.
Storage matters: keep dry ice in a well insulated container, mais never in an airtight vessel because sublimation will cause the container to rupture. Store it in a endroit bien aéré, not in a sealed room or vehicle; CO₂ gas is heavier than air and will displace oxygen. When transported inside a car, ensure fresh air circulation and place the dry ice outside the main cabin if possible.
Dry ice sublimates at different rates depending on temperature and container quality. Slabs may lose 2–10 % of their mass per day. One pound of dry ice produces 8.3 cu ft of CO₂ gas, so venting is critical. Après utilisation, unwrap remaining dry ice and leave it at room temperature in a ventilated area until it fully sublimates. Do not put dry ice in sinks or toilets; extreme cold can damage plumbing.
