Leitfaden für Trockeneisbeutel 2025: Was es ist, How to Use It

A Trockeneisbeutel keeps products at ultra‑cold temperatures by using solid CO₂ that vents as it cools.

What is a dry ice pack and why does naming matter?

In industry practice, a dry ice pack is a CO₂‑based refrigerant assembly for ultra‑cold shipping. The term can also refer to polymer sheets that hydrate and freeze, but those are not CO₂. To avoid errors, specify whether you need CO₂ dry ice pack or a polymer ice sheet, especially in regulated lanes.

When you order a Trockeneisbeutel, ask for UN1845 CO₂ if your product requires below −70 °C. Some vendors market hydratable sheets as a Trockeneisbeutel because the surface stays dry. Those sheets are reusable and safer to handle, yet they cannot match the extreme cold of a CO₂ solution. Use the polymer option for 2–8 °C or −20 °C ranges; wähle ein Trockeneisbeutel when deep‑freeze or ultra‑cold control is mandatory.

Encapsulated inserts and smoother temperature profiles

Encapsulated inserts that hold pellets in a tray reduce product cold shock and keep a steadier micro‑climate. Blocks last longer because of lower surface‑area‑to‑mass; pellets pull down fast and are easier to dose. For lanes with frequent door‑opens, a lidded insert above the payload helps keep the Trockeneisbeutel from over‑cooling sensitive vials.

Praktische Tipps & Schnelle Siege

• Door‑open events: Open slowly in a ventilated area; close promptly.

• Carton fit: Hohlräume füllen; air gaps accelerate Trockeneisbeutel burn‑off.

• Block vs pellet: Use more blocks in hot seasons; pellets to pre‑cool before handoff.

Beispiel aus der Praxis: A lab shipping enzyme kits moved from loose pellets in EPS to a lidded insert with more blocks. Hold time rose from 48 h to 72 h on a hot‑season profile, and temperature excursions went to zero across three pilots.

Wie lange hält ein Trockeneisbeutel?, and how much do you need?

Plan by time and expected sublimation, then add a safety buffer. In a mid‑size insulated shipper, the refrigerant often loses several kilograms per day. Warmer profiles, dünner Schaum, and frequent openings increase the rate; vacuum‑insulated panels slow it. FAA testing shows pellets sublimate faster than large blocks, reinforcing the “faster pull‑down vs longer hold” trade‑off.

How do you pack a shipment with a dry ice pack safely in 2025?

Entlüftung, Etikett, and separate payload from the cold source. Use a rigid insulated shipper that permits gas release; never make it air‑tight. Markieren "Trockeneis" oder "Kohlendioxid", solide", enthalten UN1845 und die Nettogewicht on the airway bill and box. Die Erklärung eines Versenders lautet nicht erforderlich when cooling non‑dangerous goods; operator variations may apply.

USPS-Hinweis (Luft): ≤ 5 lb Trockeneis pro Schreibputz; international mail is prohibited. Ensure packaging vents CO₂.

1. Pre‑condition the shipper and stage the payload at its qualified temperature.

2. Place a bottom layer of blocks or pellets in a vented sleeve or tray.

3. Add a buffer so product does not sit directly on the cold source unless validated.

4. Laden Sie die Nutzlast; top off with the remaining mass from your calculation.

5. Close without sealing air‑tight; apply marks and labels; brief the receiver on opening SOP.

Sicherheit zuerst: Belüftung, PS, and facility controls

Protect people first. Carbon dioxide can quickly displace oxygen; target below 5,000 ppm time‑weighted average and below 30,000 ppm kurzfristig. Verwenden Sie isolierte Handschuhe und Augenschutz, Fahrzeuge und Räume lüften, and avoid storing any Trockeneisbeutel in sealed containers.

One pound of dry ice becomes ~250 L von Gas, so even a small charge can over‑pressurize a closed cooler. Add a CO₂ monitor in enclosed docks and vans, train teams on safe opening, and keep SOP cards with every shipment.

2025 trends in ultra‑cold shipping

Was ist neu in diesem Jahr: Intelligente Sensoren, validated hybrid shippers, and standardized lane testing. Many teams pair a Trockeneisbeutel with PCM “buffers” to flatten spikes and cut total ice mass. Qualification to ISta 7e profiles speeds audits and reduces excursion risk on hot lanes.

Neueste Entwicklungen auf einen Blick

• VIP + PCM-Hybride: Longer hold with less CO₂; smoother profiles.

• Akzeptanz -Checklisten: Faster airline checks when cooling non‑DG goods.

• CO₂-Überwachung: Portable sensors on docks and vans to protect staff.

Market insight: Demand remains strong in healthcare and food e‑commerce. Shippers that right‑size their Trockeneisbeutel and validate to lane profiles reduce cost, Abfall, and claims.

Häufig gestellte Fragen

Is a dry ice pack the same as a polymer ice sheet?
NEIN. A Trockeneisbeutel typically uses solid CO₂ that vents; a polymer sheet is water‑based and reusable. Confirm which one your lane requires.

Do I need a dangerous goods declaration for CO₂ refrigerant?
When it cools non‑dangerous goods, a declaration is usually not required, Aber UN1845, der richtige Name, and net weight must appear on the waybill and package.

How much do I need for 48 Std.?
Start with 3–4.5 kg per day in a mid‑size VIP/EPS shipper, hinzufügen 20% Puffer, and validate with a logger.

Can I seal the box tightly to trap cold?
NEIN. Packages must vent CO₂ to avoid pressure build‑up and rupture risk. PI 954 requires gas release.

Is it safe for food?
Ja, but avoid direct contact with unpackaged food to prevent freezer burn; always use a barrier bag.

Zusammenfassung & Empfehlungen

Key Takeaways: A Trockeneisbeutel is the simplest way to achieve ≤ −70 °C on long lanes. Vent every package and mark UN1845 mit Nettogewicht. Size by time and expected sublimation plus buffer, and validate against lane profiles to prevent excursions.
