What Is a Rapid Freeze Dry Ice Pack Sheet?
Rapid freeze dry ice pack sheets are flexible blankets filled with Festes Kohlendioxid (Co₂). Wenn gefroren, they deliver extreme cold by sublimieren—turning directly from solid to gas—at about −78.5 °C. Im Gegensatz zu herkömmlichen Eisbeuteln, die zu Wasser schmelzen, dry ice sublimates without leaving any liquid residue. This unique property makes them ideal for pharmaceuticals, biologics and frozen foods that must remain below freezing throughout transit.
How Sublimation Powers Rapid Freezing
Sublimation absorbs a large amount of heat as the CO₂ transitions from solid to gas. This energy absorption keeps your cargo cold without any moisture. Traditional gel packs and water based ice packs are limited to 0 ° C bis 4 °C, but dry ice can maintain temperatures down to −78.5 °C. Pharmazeutika, vaccines and biotech samples require sub zero environments to stay potent, which is why rapid freeze dry ice sheets are commonly used for these high value shipments.
Distinguishing Dry Ice Sheets from Standard Ice Packs
Dry ice sheets differ from standard ice packs in several ways:
Temperaturbereich: Rapid freeze dry ice reaches −78.5 °C, whereas traditional ice packs hover around 0 °C.
Kühldauer: Dry ice packs maintain low temperatures for up to 72 Std., while standard ice packs last roughly 6–12 hours.
Rückstand: Dry ice leaves no water behind; standard ice melts into water and can damage packaging.
Wiederverwendbarkeit: Dry ice is single use because it sublimates completely; gel packs can be reused but can’t reach sub zero temperatures.
Rapid Freeze vs. Traditional Cooling Methods – At a Glance
| Besonderheit | Rapid Freeze Trockeneis-Packblatt | Traditioneller Eisbeutel | Bedeutung für Sie |
| Temperaturbereich | −78,5 °C (−109,3 °F) | 0 ° C bis 4 °C | Dry ice enables ultra cold shipments that gel packs can’t handle. |
| Kühldauer | Bis zu 72 Std. | 6–12 Stunden | Longer durations mean fewer refills and lower risk of temperature excursions. |
| Rückstand | Keiner (sublimiert zu Gas) | Wasser | No moisture prevents package damage and contamination. |
| Wiederverwendbarkeit | Einmalgebrauch | Wiederverwendbar | Dry ice costs more per shipment but offers extreme cold. |
| Beste Anwendungsfälle | Pharmazeutika, Biotech -Proben, Tiefkühlkost | Gekühlte Speisen und Getränke | Use dry ice for goods requiring strict temperature control. |
Rapid freeze dry ice packs clearly outperform traditional ice packs for shipments requiring deep cold. Jedoch, each has its place: gel packs or PCMs work for refrigerated goods and may be reused, while dry ice is essential for sub zero shipments.
How Do Rapid Freeze Dry Ice Pack Sheets Work?
The power of rapid freeze dry ice lies in Sublimation—the direct transition from solid to gas. As CO₂ sublimates at −78.5 °C, Es nimmt Wärme aus seiner Umgebung auf, cooling the products. This process is continuous: as long as dry ice remains, it keeps absorbing heat, providing stable ultra low temperatures. Because sublimation requires no liquid water, there is no meltwater to leak or damage goods.
To use a dry ice sheet effectively, you hydrate the super absorbent polymer cells (if it’s an SAP type) or freeze the CO₂ filled cells. The sheet becomes rigid and can wrap around cargo like a blanket. This flexibility improves edge coverage compared to pellets or blocks, reducing warm corners and hot spots. Unlike pellets that blow off CO₂ when poured, sheets stay in place and are easier to handle, making them safer and more consistent during packing.
Why Sublimation Is Key to Ultra Low Temperatures
Wärmeaufnahme: Wenn Trockeneis sublimiert, es absorbiert ca 571 kJ per kilogram of heat—many times more than water-based ice absorbs when it melts. This large energy absorption is why rapid freeze dry ice can hold temperatures below −70 °C for extended periods.
Kein Schmelzwasser: Weil es direkt in Gas übergeht, there is no risk of water pooling in your shipment, which can damage packaging or product labels.
Gleichmäßige Kühlung: Sheets wrap around the entire payload, providing uniform cooling compared with blocks that only contact one side. Uniform cooling prevents thermal gradients that might degrade sensitive goods.
Rapid Freeze vs Gel Packs and PCMs
While dry ice excels at very low temperatures, Phasenwechselmaterial (PCMs) and gel packs cover other ranges. PCMs can maintain narrow temperature bands from −25 °C to +25 °C and last 24–96 hours. Gel packs are best for chilled goods at 0 ° C bis 5 °C and last 8–24 hours. Gelpackungen schmelzen zu Wasser, so they can leak or freeze sensitive goods. PCMs require pre conditioning (Einfrieren oder Erhitzen) but offer reusable, präzise Temperaturregelung.
Nutzungstipps: Maximizing Performance
To get the most out of rapid freeze dry ice sheets, Folgen Sie diesen Best Practices:
Pre Cool Containers and Product
Always pre cool the shipping container and payload before adding dry ice. This prevents the ice from wasting energy cooling down the container itself. Zum Beispiel, refrigerate your insulated box overnight or add gel packs briefly to bring it close to the shipping temperature.
Layering Method – The Dry Ice “Sandwich”
Verwenden Sie das Sandwich-Methode to achieve even cooling: place a layer of dry ice at the bottom, load the product in the middle and add another layer of dry ice on top. This layout ensures the entire payload remains within the required temperature range. Für dünne Bleche, you can wrap them around the sides as well. Avoid direct contact between dry ice and the product by using a divider or dunnage; direct contact can freeze or crack glass vials.
Stellen Sie eine ordnungsgemäße Belüftung sicher
Wenn Trockeneis zu CO₂-Gas sublimiert, it can pressurise sealed containers. Always ensure that your packaging has vent holes or breathable material to allow CO₂ to escape. Versiegeln Sie niemals Trockeneis in einem luftdichten Behälter; Der Druckaufbau kann eine Explosion verursachen. Zum Beispiel, plastic coolers should have vent plugs removed or holes drilled.
Wear Protective Gear and Plan for Safety
Dry ice reaches extremely cold temperatures that can cause frostbite. Tragen Sie immer isolierte Handschuhe und eine Schutzbrille beim Umgang mit Trockeneis. Keep dry ice out of reach of children and pets and do not ingest or use it in drinks. In case of accidental ingestion or over exposure, seek medical attention immediately and watch for signs like panting, headaches or blue lips.
Disposal and Room Ventilation
When finished with dry ice, unwrap it and leave it to sublimate in a well ventilated area away from animals or children. Never throw dry ice into garbage or down a sink or toilet, as the cold temperature can damage plumbing. If you can’t leave it outside, place it on a solid surface, open windows and ensure the room is ventilated while the ice evaporates. Sublimation can take several hours to days depending on conditions.
Regulatory Compliance and Safety Standards
Shipping with dry ice is regulated because CO₂ release can displace oxygen. Solid CO₂ is classified as a Class 9 Gefahrgut gemäß UN 1845. Auf den Paketen muss der korrekte Versandname angegeben sein, UN-Nummer und Nettogewicht auf derselben Oberfläche wie das Gefahrenetikett. Etiketten müssen mindestens sein 100 MM Quadrat. If the package contains more than 30 kg Trockeneis, the letters on the label must be at least 12 mm hoch. Air bills must state “UN 1845, „Trockeneis“ und geben Sie die Anzahl der Pakete und das Nettogewicht an. Only trained staff should prepare shipments and follow carrier rules; Anbieter wie FedEx bieten Trockeneis an 200 kg pro Packung und erfordern eine Belüftung.
Best Practices für die Sicherheit: Hazard vs Control
The table below summarises the main hazards associated with dry ice and the control measures you should follow:
| Gefahr | Beschreibung | Kontrollmaßnahmen |
| Frostbite and skin burns | Dry ice can freeze skin on contact | Wear insulated gloves and avoid direct contact when handling dry ice |
| CO₂ -Aufbau & Erstickung | Sublimation releases CO₂ gas that displaces oxygen, causing suffocation | Use dry ice in ventilated areas; Trockeneis nicht in luftdichten Behältern verschließen |
| Druckexplosion | Trapped gas builds pressure in sealed containers | Ensure packaging has vent holes or breathable materials; never seal dry ice |
| Unsachgemäße Entsorgung | Disposing in garbage, drains or toilets can damage plumbing | Allow dry ice to sublimate outdoors or in a ventilated room; avoid sealed bins |
