Shipping With Cold Packs: When Is It the Smart Choice?
Cold packs excel when you must keep products above the freezing point and within a tight 2–8 °C window. They release steady, gentle cooling and avoid freezer burn. Pack roughly one‑third of payload weight in gel packs to reach 48 hours, then adjust for lane temperature swings.
Cold packs shine for chocolates, Kosmetika, and pharma vials that lose integrity below 0 °C. They’re leak‑free, wiederverwendbar, and typically classify as non‑hazardous—simplifying paperwork and training.
How Many Gel Packs Do You Really Need?
| Nutzlast (kg) | 24 H -Packungen (kg) | 48 H -Packungen (kg) | 72 H + Dry -icee Boost? |
|---|---|---|---|
| 2 | 0.5 | 0.7 | Add 0.5 kg dry ice |
| 5 | 1.2 | 1.7 | 0,8 kg Trockeneis hinzufügen |
| 10 | 2.5 | 3.5 | Fügen Sie 1,5 kg Trockeneis hinzu |
Tipp: Pre‑chill packs overnight to raise effective cooling capacity by ~12 %.
User‑Ready Pointers
-
Meal‑kit lanes: Use three 500 g gel packs around a 1.5 kg salad kit for 48 h summer transit.
-
Cosmetic samplers: Ship at ambient; position one room‑temperature gel pack on top to stop freezing in winter.
Real Case: A boutique chocolatier cut melt claims from 8 % to 1 % by swapping foam coolers for drain‑friendly gel packs on 2‑day ground routes.
Shipping With Dry Ice: When Is It Unbeatable?
Dry ice is the go‑to for shipments that must stay frozen solid. At –78 °C it absorbs 571 kJ/kg during sublimation, delivering deep‑freeze power that lasts up to 72 hours with the right load plan. Pack half the payload weight in dry ice for overnight, Gleiches Gewicht für 48 Stunden, und 1,5 × für 72 Stunden.
Ideal for ice cream, frozen proteins, and cell‑therapy biologics that tolerate extreme cold.

| Nutzlast (kg) | Top Load 24 h (kg) | Spitze + Bottom 48 h (kg) | 72 H (kg) |
|---|---|---|---|
| 5 | 1.5 | 2.5 | 5 |
| 10 | 2.5 | 5 | 7.5 |
| 20 | 5 | 10 | 15 |
Always place dry ice über the product—cold air sinks.
Safety Snapshot
-
Locker tragen, Isolierte Handschuhe; Vermeiden Sie den Kontakt mit nackten Hand.
-
Vent every package (20–30 mm² vent area) to release CO₂.
-
Label “UN1845—Dry Ice” and keep under the 2.5 kg exemption when possible.
Cold Packs vs Dry Ice: Kosten, Sicherheit & Regulations Compared
| Faktor | Cold Packs | Trocknung | What It Means for You |
|---|---|---|---|
| Temperaturbereich | 2 – 15 °C | –78 °C core | Wählen Sie nach Produkttoleranz |
| Hazard Class | Generally non‑hazardous | Class9 if > 2,5 kg | Impacts paperwork/training |
| Typical Cost/kg | USD $2.00 | USD $1.20 | Trockeneis billiger pro kg; packs cheaper on light loads |
| Zeit halten (48 H) | Needs 0.35 kg/kg payload | Needs 1 kg/kg payload | Plan box size accordingly |
| Entsorgung | Recyclable film/gels | Sublimates zu Gas | Match customer convenience |
Fazit: For chilled goods, cold packs win on simplicity and compliance. For deep‑frozen loads or long lanes, dry ice pays off in thermal security.
2025 Innovations Shaping Shipping With Cold Packs vs Dry Ice
The cold‑chain landscape is evolving fast:

FAQ
How do I stop cold packs from sweating on long trips?
Wrap packs in absorbent paper or use sweat‑proof film to cut condensation.
Can I combine dry ice and cold packs in one box?
Ja. Position gel packs beneath the product to buffer –78 °C and slow dry‑ice burn‑off for extra 8‑10 hours.
Is dry ice allowed in air freight?
Under 2.5 kg per package only needs the UN1845 label; darüber, Class 9 documentation applies.
