What is a flexible ice dry ice pack sheet and how does it differ from standard ice packs?
Direct answer and core benefits
Flexible Trockeneisbeutelplatten sind dünn, pliable blankets filled with solid carbon dioxide (Trockeneis) or advanced phase change materials. Each sheet contains super absorbent polymer cells that are hydrated before freezing to create a network of pockets that encapsulate CO₂. Wenn gefroren, the sheet becomes a flexible cold layer that can wrap around irregularly shaped cargo. Denn Trockeneis sublimiert (geht direkt von fest in gasförmig über) at –78.5 °C, it can keep goods ultra cold without leaving moisture or residue. Traditionelle Eisbeutel, dagegen, rely on water freezing at 0 °C and melt into liquid as they warm. The ultra cold temperature of dry ice sheets allows perishable items like vaccines, biologics and frozen seafood to remain well below freezing for days, making them ideal for long distance shipping.
Erweiterte Erklärung
Unlike rigid bricks or loose pellets, flexible sheets conform to the shape of the product, improving contact and reducing dead air space. To prepare a dry ice sheet, the super absorbent polymer cells are hydrated with water and then frozen. Wenn es wärmeren Temperaturen ausgesetzt ist, Trockeneis untermauert, absorbing heat at a rate of 571 kJ pro Kilogramm. This endothermic reaction maintains a cold environment without creating liquid water, preventing soggy packaging and eliminating cross contamination concerns. Standard gel packs melt at 0 °C and release water, while phase change materials may maintain more moderate temperatures (Z.B., 2–8 °C oder –20 °C) but cannot reach the –78.5 °C range of dry ice. Because flexible dry ice sheets maintain such low temperatures, they are especially useful for shipping mRNA vaccines, biologic samples and frozen desserts that must remain far below freezing.
Comparing dry ice sheets, Gelpacks und PCMs
| Kühlmedium | Typischer Temperaturbereich | Regulatorische Klassifizierung | Rückstände nach Gebrauch | Beste Anwendungsfälle | Auswirkungen auf die reale Welt |
| Flexible Trockeneisplatte | –78,5 °C bis –20 °C; can hold ultra cold temperatures for 24–72 hours | Klasse 9 Gefahrgut; erfordert UN 1845 Kennzeichnung und besondere Handhabung | Sublimiert direkt zu CO₂-Gas, hinterlässt keine Flüssigkeitsrückstände | Gefrorene Arzneimittel, Biologika, Spezialität aus Meeresfrüchten | Keeps products well below freezing; no moisture contamination |
| Gelpackung | 0 ° C bis 5 °C; mäßige Kühlung für 12–48 Stunden | Ungefährlich; leicht zu handhaben | Schmilzt in Wasser, eine auslaufsichere Verpackung erforderlich ist | Frische Produkte, Mahlzeiten, Kurzstreckentransporte | Provides mild cooling but not ultra cold temperatures |
| Phasenwechselmaterial (PCM) Blatt | –20 °C bis –70 °C; Stabiles Temperaturband für 24–72 Stunden | Often non hazardous because PCMs are non toxic | Normalerweise keine Rückstände; PCMs absorbieren bei Phasenübergängen Wärme | Biologika erfordern strenge Temperaturbereiche von 2–8 °C oder –20 °C | Bietet wiederverwendbar, narrow band temperature control without dry ice gas |
Praktische Tipps und Empfehlungen
Für ultrakalte Sendungen: Use flexible dry ice sheets when your cargo must remain below –20 °C for more than a day. The sublimation of dry ice delivers powerful cooling while avoiding liquid leakage.
For moderate cold conditions: Gel packs are inexpensive and simple to use for perishable foods that require refrigeration rather than freezing.
For precise temperature ranges: PCM sheets are ideal when regulatory requirements demand a tight temperature band (Z.B., 2–8 ° C). They are often classified as non hazardous, reducing compliance burdens.
Beispiel aus der Praxis: A biotech company shipping mRNA vaccines used flexible dry ice sheets that wrapped around each vial, maintaining –75 °C for 72 hours despite external temperatures reaching 25 °C. Because the sheets sublimated rather than melted, the vials arrived completely dry and uncontaminated.
How do you size and apply flexible dry ice pack sheets for maximum effectiveness?
Direct answer and core guidelines
Choosing the right sheet thickness and layering method is essential for maintaining target temperatures during transit. The rule of thumb is to match the weight of dry ice to the weight of the product (A 1:1 Verhältnis) and to select sheet thickness based on transit time. Zum Beispiel, A 12 mm-Blech hält in der Regel extrem kalte Temperaturen bis zu 24 Std., ein 18 mm sheet lasts about 48 Std., und a 24 mm-Blech hält gefrorenen Temperaturen bis zu stand 72 Std.. When layering, the sheet should fully wrap around the product or be sandwiched between layers of goods and insulation.
Expanded explanation and sizing details
Dry ice sheets come in various thicknesses and sizes. Because sublimation happens on the surface, the rate of sublimation decreases when the sheet is insulated and when ambient temperature is lower. The following guidelines will help you size your sheet correctly:
Assess product sensitivity and transit duration: If your cargo must remain below –20 °C for 48 Std., Wählen Sie eine 18 mm Blech. Für 72 Std., opt for a 24 mm Blatt oder mehrere 18 mm sheets layered together.
Calculate dry ice weight: Determine the weight of the product and match it with an equivalent weight of dry ice. Zum Beispiel, A 5 kg box of frozen seafood would require approximately 5 kg Trockeneis in Blattform.
Prepare the sheet properly: Hydrate the polymer cells evenly before freezing. This step ensures uniform sublimation and prevents brittle spots. Pre chill the product and insulated container to reduce the thermal load on the sheet.
Strategisch schichten: For long hauls, wrap the product entirely with the sheet (full wrap method) or place sheets on the top and bottom with the product in between (Sandwich-Methode). This ensures consistent contact and reduces temperature gradients.
Abdichten und isolieren: Use vented insulated containers to allow CO₂ gas to escape while retaining cold air. Combine the sheet with vacuum insulated panels or expanded polystyrene foam for better thermal performance.
Sizing guidelines table
| Transitdauer | Empfohlene Blechstärke | Approximate dry ice weight (kg) per kg of product | Praktische Bedeutung |
| Bis zu 24 Std. | 12 mm flexible Trockeneisplatte | 1 kg Trockeneis pro 1 kg Produkt | Suitable for overnight shipments such as next day pharmaceuticals; ensures product remains below –20 °C for one day. |
| 24–48 Stunden | 18 mm Blatt oder zwei 12 mm Schichten | 1–1,5 kg Trockeneis pro kg Produkt | For two day deliveries and international flights; Die Schichtung sorgt für redundante Kühlung. |
| 48–72 Stunden | 24 mm sheet or combination of three 12 mm-Blätter | 2 kg Trockeneis pro kg Produkt | Extended transit for vaccines and cell therapies; multiple layers maintain –75 °C for three days. |
Tipps für bestimmte Szenarien
Laborproben: Label each specimen bag separately and wrap with a flexible sheet to avoid cross contamination. Place absorbent pads underneath to capture any condensation from the outer environment.
Service für Essenssets: Lebensmittel vorfrieren, dann wickeln Sie sie mit einem 18 mm-Blech und legen Sie weitere Blätter darauf. The flexible nature of the sheet allows it to conform to irregular shapes (Z.B., whole fish or stacked steaks), ensuring uniform cooling.
Pharmazeutischer Vertrieb: Verwenden Sie a 24 mm sheet for high value biologics that must remain below –70 °C. Employ real time temperature sensors embedded in the sheet to monitor conditions during transit.
Tatsächlicher Fall: A meal kit company switched from rigid dry ice blocks to flexible sheets. By fully wrapping each food parcel with a 12 mm sheet and pairing it with an insulated liner, the company reduced total dry ice usage by 20 % while still maintaining –18 °C for 48 Std.. Customer satisfaction improved as packages arrived dry and intact.
What safety and regulatory considerations apply to flexible dry ice sheets?
Direct answer and core requirements
Trockeneis wird als Klasse eingestuft 9 Gefahrgut im internationalen Luftverkehr (Hier ist PI954) und USA. Verkehrsministerium (PUNKT) Vorschriften. Every package containing dry ice must display the proper shipping name “Carbon dioxide, fest“ oder „Trockeneis“.,” die UN-Nummer UN 1845, und das Nettogewicht von Trockeneis. Hazard labels must be at least 100 mm on each side, and the total weight of dry ice per shipment must not exceed 200 kg. Flexible sheet formats do not change these requirements; they simply influence handling and packaging practices.
Expanded explanation of safety practices
Sublimation of dry ice produces CO₂ gas, which can displace oxygen in enclosed spaces and pose a suffocation hazard. To handle flexible dry ice sheets safely:
Wear personal protective equipment: Always use insulated gloves and eye protection when handling dry ice sheets. Avoid touching the sheets with bare skin to prevent frostbite.
Provide adequate ventilation: Use vented containers or shipping boxes with pressure relief valves so that CO₂ gas can escape. Do not seal dry ice inside airtight containers or plastic bags.
Richtig beschriften: Befestigen Sie die Klasse 9 Gefahrenkennzeichnung und Nettogewicht des Trockeneises beachten. Include orientation arrows to indicate the correct upright position.
Follow shipper limits: Airlines and couriers may impose additional restrictions; Zum Beispiel, some carriers limit dry ice shipments to 10 kg pro Paket für Passagierflugzeuge. Always consult the latest IATA and DOT guidelines.
Verantwortungsbewusst entsorgen: Lassen Sie das restliche Trockeneis an einem gut belüfteten Ort, fern von Kindern und Haustieren, sublimieren. Do not flush dry ice down the drain or place it in a trash compactor. Einmal sublimiert, the polymer sheet can be recycled according to local regulations.
Schulung und Dokumentation: Denn Trockeneis ist gefährlich, personnel should complete basic hazardous material training. Documents must accompany shipments, stating the net weight and proper shipping name. For PCMs and certain gel packs, the non hazardous classification reduces training and paperwork.
