Was sind 24 Hour Dry Ice Packs and How Do They Work?
24 hour dry ice packs consist of pellets or slices of solid carbon dioxide sealed in vented packaging that releases gas as the dry ice warms. Because dry ice sublimates at around –78.5 °C, these packs maintain ultra cold temperatures for 24–72 hours without melting. Im Gegensatz zu Gelpackungen, which thaw at 2–8 °C and leave water behind, dry ice keeps shipments completely frozen and dry. The main keyword appears early to highlight the subject, and understanding sublimation sets the stage for the rest of this article.
Shipping frozen meat, Meeresfrüchte, vaccines or biologic samples requires reliable cold. Dry ice packs deliver colder temperatures than gel packs because CO₂ absorbs more heat when changing state. Each pack holds pellets that turn into gas, absorbing warmth and keeping your goods at –78.5 °C for up to three days. Gelpackungen, dagegen, maintain chilled conditions around 2–8 °C. Since dry ice produces no liquid, packages stay dry and there is no condensation or soggy packaging. This makes 24 hour dry ice packs ideal for shipments that must remain completely frozen during transport.
Sublimation verstehen: Warum Trockeneis nicht schmilzt
Trockeneis ist Kohlendioxid in fester Form. Instead of melting like water ice, Es SULBLIMATE – it turns directly into gas. This process occurs at –78.5 °C, which is why dry ice packs are so cold. Sublimation means there is no liquid runoff to damage packaging or leak onto products. Denn das Gas ist schwerer als Luft, you should place dry ice packs above your goods so the cold air can sink and circulate.
| Kühlmethode | Temperaturbereich | Typische Dauer | Was es für Sie bedeutet |
| Mini-Trockeneisplatte | –78,5 °C bis –18 °C | 24–48 h | Ideal for pharmaceuticals or biologics that require ultra low temperatures; verhindert Feuchtigkeit |
| Einweg-Trockeneisbeutel | –78,5 °C | Bis zu 72 H | Pflegt gefrorenes Fleisch, Meeresfrüchte oder Impfstoffe; single use convenience and no melting water |
| Gelpackung (2–8 ° C) | 2–8 ° C | Bis zu 48 H | Keeps produce or medicines cool without freezing; wiederverwendbar, kann aber auslaufen |
| Traditionelle Wasserpackung | ≈ 0 °C | 24–36 h | Cheapest for short journeys; limited thermal mass and produces meltwater |
Praktische Tipps und Empfehlungen
Richtig hydrieren und einfrieren: Activate dry ice sheets by hydrating the polymer cells and freezing them for at least 24 Std..
Kühlen Sie Ihre Produkte vor: Freezing or chilling goods before packing reduces the heat load and extends cooling duration.
Verwenden Sie für längere Reisen größere Laken: Bigger packs contain more CO₂ and last longer.
Packungen darauf platzieren: Kalte Luftwaschbecken, so position dry ice above your products; für lange Strecken, surround goods with packs and combine them with phase change materials (PCMs).
Überwachen Sie die Temperatur: Employ data loggers or IoT sensors to track internal temperatures and adjust the number of packs.
Tatsächlicher Fall: Ein Pharmaunternehmen versendet 8 lb of frozen vaccine vials from Los Angeles to Chicago used an 8 lb 24 hour dry ice pack and added 30 % extra dry ice for summer conditions. By pre freezing the vials to –20 °C and using vacuum insulated panels, the shipment remained below –70 °C for 72 Std..
Dimensionierung und Verpackung 24 Stunden-Trockeneisbeutel: How Much Do You Need?
The right quantity of 24 hour dry ice packs depends on product weight, Transitzeit, Isolationsqualität und Umgebungstemperatur. Eine einfache Faustregel ist a 1:1 Verhältnis von Trockeneisgewicht zu Produktgewicht für 48-Stunden-Lieferungen. For a 24 hour trip, you can often use slightly less, but factors like summer heat or complex routes may require extra packs. For shipments longer than two days, A 1.5:1 Verhältnis wird empfohlen.
Experts also recommend estimating sublimation loss. Dry ice sublimates at a rate of about 5–10 lb per 24 Stunden in einem gut isolierten Behälter. Mercury, a logistics provider, suggests using 5–10 lb of dry ice per day for items weighing up to 12.5 lb; a two day shipment requires at least 20 lb. Selecting good insulation can extend pack life by reducing sublimation losses.
When calculating your needs, consider route complexity and insulation upgrades. Adding 25–35 % extra dry ice during summer or when delays are expected ensures sufficient cooling. Upgrading to vacuum insulated panels can reduce required dry ice by 10–25 %. Filling void spaces with foam or paper also reduces sublimation. Hybrid packouts combining dry ice with PCMs buffer temperature fluctuations and extend duration beyond 72 Std..

| 10 | 5 | 10 | 15 | Verwenden Sie a 1:1 ratio for up to two days, Und 1.5:1 für 72 Std. |
| 15 | 8 | 15 | 23 | Bei mittelgroßen Ladungen extra hinzufügen; Achten Sie bei der Verwendung auf Belüftung >20 lb |
| 20 | 10 | 20 | 30 | Größere Ladung benötigt proportional mehr Trockeneis, um über weite Strecken gefroren zu bleiben |
| 30 | 10 (Spitze) + 5 (unten) | 20 (Spitze) + 10 (unten) | 30 (Spitze) + 15 (unten) | Die Aufteilung von Trockeneis zwischen Ober- und Unterseite sorgt für eine gleichmäßige Kühlung schwerer Sendungen |
| 40 | 15 (Spitze) + 5 (unten) | 25 (Spitze) + 15 (unten) | 40 (Spitze) + 20 (unten) | Schwere Fracht kann bis zu erfordern 40 LB für 72 Std.; Plan für die Handhabung und behördliche Grenzwerte |
Practical Sizing Tips and Advice
Assess product weight and temperature requirements: Determine whether your goods must stay at –70 °C, –20 °C oder 2–8 °C, and adjust dry ice weight accordingly.
Consider route complexity and transit duration: Add 10–15 % more dry ice for multi handoff routes or potential delays.
Upgrade insulation to reduce weight: Vacuum panels or reflective liners can lower dry ice requirements by up to 25 %.
Verwenden Sie Hybrid-Packouts: Combining dry ice with PCMs helps buffer temperature swings and extends cooling to 72 Stunden oder mehr.
Vorbereiten und vorgefrieren: Chill products and packaging before assembly to reduce initial heat load.
Beispiel aus der Praxis: Ein Exporteur von Meeresfrüchten ersetzte Wassereis durch kleine Trockeneisscheiben und belüftete Kisten. By matching the dry ice weight to the product weight and filling voids, Sie haben das Sendungsgewicht um reduziert 30 % und Fischfilets eingefroren 48 Stunden ohne Lecks.
Choosing Between 24 Hour Dry Ice Packs and Gel Packs: Was ist besser??
Deciding between 24 hour dry ice packs and gel packs depends on the temperature your product requires and how long it must stay cold. Dry ice packs maintain –78.5 °C and are ideal for frozen goods, while gel packs keep items between 2–8 °C and are best for chilled products. Zum Beispiel, frozen meat or vaccines must remain well below zero; chocolates and injectable medicines only need refrigeration..
Gel packs are water based and melt around 0 °C, so they cannot sustain deep freeze conditions. Jedoch, gel packs protect products that must not freeze. They also help supplement dry ice: combining gel packs and dry ice slows sublimation and extends cooling. When selecting a cooling method, Berücksichtigen Sie die Produktempfindlichkeit, Versanddauer, cost and customer experience. Dry ice is regulated as a hazardous material and requires handling training, while gel packs are unregulated and simpler for end users.

Praktisches Szenario: A meal kit company used a hybrid approach—placing dry ice packs around frozen proteins and gel packs beside vegetables. This combination kept all ingredients within their proper temperature ranges and reduced confusion for customers.
Safe Handling and Regulatory Considerations for 24 Stunden-Trockeneisbeutel
Trockeneis ist extrem kalt und wird als Gefahrgut eingestuft (Und 1845), so proper handling is essential. Tragen Sie isolierte Handschuhe, Schutzbrille und lange Ärmel, um Erfrierungen vorzubeugen. Fassen Sie Trockeneis niemals mit bloßen Händen an; Hautkontakt kann zu schweren Verletzungen führen. Because dry ice releases large volumes of CO₂ gas as it sublimates, packages must be vented to prevent pressure buildup and avoid asphyxiation.
Regulatory agencies require that packages containing dry ice display a Class 9 hazard label and indicate the net weight. Many airlines limit dry ice quantities to about 5.5 lb (2.5 kg) per package and require proper documentation. In den Vereinigten Staaten, Sendungen vorbei 5.5 lb must comply with Title 49 des Code of Federal Regulations; international shipments must follow IATA rules. Gel packs are not regulated and require no special labels.

Entsorgung: Let remaining dry ice sublimate outdoors; never dispose of it in sinks or trash cans where the extreme cold can damage fixtures.
Environmental Impact and Sustainability of 24 Stunden-Trockeneisbeutel
Dry ice is essentially recycled CO₂, produced by capturing carbon dioxide from industrial processes such as ammonia synthesis or ethanol production. This means the CO₂ used in dry ice is repurposed rather than newly emitted. Während das Trockeneis sublimiert, it releases CO₂ gas back into the atmosphere, so efficient use reduces the overall footprint.
Sustainability depends on using the right amount and improving insulation. Vacuum insulated panels or reflective liners reduce dry ice consumption, which cuts both cost and CO₂ emissions. Hybrid systems combining dry ice with phase change materials or gel packs extend cooling without increasing CO₂ output. In 2025, reusable dry ice packs are emerging; these can be refilled hundreds of times and reduce waste by 20 %.
