Was ist a Trockeneisbeutel für den Versand von Lebensmitteln—and when should you use it?
A dry ice pack for shipping food keeps contents below freezing by sublimating at –78.5 °C, giving long, dry cooling with no meltwater. It is ideal for frozen meats, Meeresfrüchte, pastry, and ice cream on 24–72‑hour routes. Plan roughly 5–10 lb (2.3–4,5 kg) pro 24h per midsize insulated shipper.
Use it when the product must arrive frozen, not just chilled. Avoid dry ice for items that must not einfrieren (Z.B., fresh berries at 2–8 °C); choose gel packs instead. You’ll get cleaner boxes, fewer leaks, and longer hold times than with wet ice.
Dry ice pack vs. gel packs for shipping food
Key differences in real shipments—what you’ll notice on delivery.
| Kältemittel | Practical range | Typical hold time* | Was bedeutet dies für Sie |
|---|---|---|---|
| Trockeneisbeutel für den Versand von Lebensmitteln | ~–78.5 °C vapor blanket | 24–72+ hours | Arrives rock‑solid; no water. Requires venting and gloves. |
| Gel -Eisbeutel | 0 °C to –18 °C | 12–48 Stunden | Great for 2–8 °C foods; won’t keep items frozen on long routes. |
| Wet ice | 0 ° C | 6–24 Stunden | Billig, but soggy boxes and short life. |
*Hold time varies with insulation thickness, load mass, und Umgebungswärme.
Praktische Tipps, die Sie heute bewerben können
-
Zu Beginn der Woche versenden. Avoid weekend stranding that outlasts your dry ice.
-
Pre‑freeze the load. Dry ice maintains frozen state; it’s not a fast freezer.
-
Trockeneis darauf legen. Kaltes Waschbecken; top placement gives better coverage.
Wirklicher Fall: A bakery shipping ice‑cream cakes added 14 lb of dry ice to a 2‑inch EPS box for a two‑day route. Cakes arrived rock‑solid even after a 10‑hour hub delay thanks to top‑loading and vented lid.
How do you pack a dry ice pack for shipping food step‑by‑step?
Core setup that works across carriers and lanes.
-
Choose the shipper. Use a tight‑fitting EPS or VIP insert inside a strong corrugated box.
-
Voraussetzung. Freeze products to target temperature before packing.
-
Wrap & separate. Bag food items; add a barrier (cardboard tray) between product and dry ice.
-
Add dry ice packs. With gloves, Ort oben (and optionally around sides) for vapor coverage.
-
Vent the container. Never airtight‑seal; Lassen Sie CO₂ entkommen.
-
Hohlräume füllen. Use paper or pads to prevent shifting and thermal leaks.
-
Schließen, tape, und Etikett. Add required marks and net dry‑ice weight.
Venting and placement best practices (don’t skip)
-
Leave a small lid gap or use vented lids. This prevents pressure buildup.
-
Vermeiden Sie direkten Kontakt. A thin spacer protects delicate foods from surface freeze‑cracking.
-
Double‑box heavy loads. Dry ice can embrittle thin plastics; use sturdy outers.
| Packing layer | Warum ist es wichtig | What to use | Impact for you |
|---|---|---|---|
| Außenschachtel | Stack strength | 44‑ECT corrugated | Fewer crush damages |
| Isolierung | Heat barrier | 1.5–2″ EPS or VIP | Longer hold times |
| Spacer | No product contact | Cardboard/bubble | Prevents freeze‑burn |
| Trockeneisbeutel für den Versand von Lebensmitteln | Cold source | Slabs or pellets in paper | Even vapor, cleaner handling |
How much dry ice pack for shipping food do you need?
Schnelle Regel: Fangen Sie an 8 lb per 24 h per cubic foot of insulated space, then adjust for route and weather. Hot lanes or thin insulation need more. Always round up for delays.
Fast estimator (copy‑paste logic)
Thumb‑table for common boxes
| Box (innere) | Route | Climate | Trockeneisbeutel für den Versand von Lebensmitteln (recommended) |
|---|---|---|---|
| 10″×10″×10″ (~0.6 ft³) | 24 H | Mäßig | 6–7lb |
| 12″×12″×12″ (~1.0 ft³) | 48 H | Heiß | 12–14lb |
| 14″×14″×14″ (~1.6 ft³) | 72 H | Mäßig | 20–24 lb |
Für die Spitze: Split dry ice into several small packs instead of one large block for more even vapor.

Compliance checklist you can print:
-
Eigenname & Und: „Kohlendioxid, solide (Trockeneis), Und 1845.”
-
Gefahrenklasse: Klasse 9 (Verschiedenes).
-

-
Belüftung: Verpackung muss Lassen Sie CO₂ entkommen.
-
Dokumentation: Follow your carrier’s dry‑ice declaration steps for air.
-
Ausbildung: Staff preparing Luft dry‑ice shipments should be HazMat/DG‑trained.
Recipient safety note: Include a slip: “Open in a ventilated area; do not touch dry ice with bare hands; let remaining dry ice evaporate outdoors.”
Receiving, Lagerung, and disposal—what should your team do?
-
On arrival: Move the box to a ventilated space. Don’t store in a sealed room or vehicle.
-
Handhabung: Verwenden Sie isolierte Handschuhe; avoid metal surfaces that can frost‑bond to skin.
-
Entsorgung: Let any leftover dry ice evaporate away from people and pets. Never bin, sink, or drain.
2025 cold‑chain developments and trends
What’s new this year—and how it affects a dry ice pack for shipping food.
More shippers are switching to CO₂‑recaptured “green” dry ice, ultra‑cold reusable PCM packs (–70 °C class), Und sensor‑enabled shippers that track temperature and CO₂ levels in real time. These upgrades reduce scope‑3 emissions, improve lane reliability, and boost customer confidence.
Neueste Fortschritte auf einen Blick
-
Grüne Co₂ -Beschaffung: Lower‑impact dry ice from captured emissions.
-
–70 °C PCM blocks: Reusable alternatives for select lanes and returns.
-
Smart vents & CO₂ alerts: Prevent over‑pressurization and enable proactive handling.
Market insight: Demand for frozen e‑commerce foods and biologics continues to rise, pushing longer lanes and hotter last‑mile conditions. Expect higher adoption of thicker insulation (VIP) and hybrid coolant strategies to reduce total dry‑ice mass while preserving outcomes.
FAQ
Q1: Can I put a dry ice pack for shipping food in a regular cooler?
Ja, Aber vent the lid. Co₂ muss entkommen. Most plastic coolers are fine for short routes, though very thin walls shorten hold time.
Q2: How do I prevent freezer‑burn or cracking?
Insert a spacer (cardboard tray) so dry ice doesn’t directly touch delicate foods. Bag products to avoid desiccation.
Q3: What if the route extends unexpectedly?
Pack a 15–25% Puffer of dry ice and ship early in the week. Consider a 2‑day service upgrade on hot lanes.
Q4: Is a dry ice pack for shipping food safe in cars or vans?
Transport with windows slightly open. CO₂ can build up in confined vehicles.
Q5: Do I need special labels for ground shipments?
You must still mark “Dry Ice, UN 1845” Und Nettogewicht and use vented packaging. Air has stricter rules.
Q6: When should I choose gel packs instead?
If the target is 2–8 ° C, gel packs beat dry ice. They won’t freeze produce or chocolate.
Zusammenfassung & Empfehlungen
What matters most: Verwenden Sie a Trockeneisbeutel für den Versand von Lebensmitteln when you must arrive frozen; pre‑freeze loads; place dry ice oben; Verpackung weiter entlüftet; markieren Und 1845 + Netz kg; and pack 15% extra Für Verzögerungen. These basics prevent thaw, Lecks, and compliance issues.
