Was sind die 2025 Regeln? Hier ist PI954, FedEx/UPS specifics, USPS 5 lb air limit.
How many dry ice packs for shipping food 72 Stunden brauchen Sie?
Kurze Antwort: Start at ~12 lb for a small frozen payload in a 1.5–2″ EPS shipper, then adjust for heat, Isolierung, und Nutzlastmasse. That baseline reflects field usage (≈5 lb first day, then 3–4 lb per extra day). Always pilot‑test and data‑log.
Why it varies: Heat gain comes from ambient temps, R -Wert, leerer Raum, and starting payload temp. ISTA 7E provides 72/144‑hour parcel profiles to validate your design before scale.
Quick 2‑minute estimator (Faustregel)
Beispiel: 82 °F lane, EPS 1.75″, 8 lb payload → 12×1.2×1.0×1.2 ≈ 17.3 lb. Use this to right‑size Trockeneisspülung zum Versand von Lebensmitteln 72 Std., then confirm in chamber or live runs.
How to pack dry ice packs for shipping food 72 Stunden sicher?
Kernschritte: Prefreeze to 0 °F, wrap food (no direct dry‐ice contact), place product centered, Trockeneis oben with side batts as needed, minimieren Sie den Kopfspace, sicherstellen Entlüftung, Dann label/mark for the chosen mode.
Venting matters: Dry ice must off‑gas; Tun nicht make the liner or outer carton airtight. UPS and 49 CFR 173.217 both require ventilation; UPS also advises against airtight boxes.
Food‑safe and handler‑safe basics
-
Kein direkter Kontakt: Wrap/contain foods to avoid CO₂ burn.
-
PS & Luft: Handschuhe, Augenschutz, belüftet packout area; CO₂ TWA 5,000 ppm, Idlh 40.000 ppm.
-
Conversion reality: 1 lb dry ice → ~8.3 ft³ CO₂ gas; plan vent paths.
Quick packout bill‑of‑materials (Stückliste)
| Artikel | Zweck | Typische Spezifikation | Warum es dir wichtig ist |
|---|---|---|---|
| Isolierter Versender | Cut heat gain | EPS 1,5–2 " / PUR ~1″ / VIP ~1″ | R‑value drives dry‑ice mass. VIP often shrinks box & Gewicht. |
| Trockeneis | Keep payload ≤0 °F | Slabs on top + side batts | Slabs last longer than pellets; top‑load for cold sink. |
| Liner & wickeln | Lebensmittelsicherheit | Feuchtigkeitsbarriere; Doppelbeutel | Prevents direct contact & Gefrierbrand. |
| Labels/marks | Annahme | Klasse 9 + “Dry Ice/UN 1845” + Netz kg | Required by IATA/air carriers; avoids tender rejections. |
Practical tips that cut melt risk
-
Hohlräume füllen so cold gas stays around product, not empty space.
-
Pre‑chill the empty shipper (overnight if possible).
-
Versand Mo–Mi um Wartezeiten am Wochenende zu vermeiden.
Real -World -Fall: A 2″ EPS shipper with 5 lb frozen payload held ~ 72H Verwendung ~12–13 lb dry ice in summer validation, with a top slab and side batts.
Which insulation makes 72 hours easier with dry ice packs for shipping food?
Fazit: Higher R‑value reduces dry‑ice mass and outer‑box size.
EPS vs. PUR vs. VIP—what changes for your 72‑hour plan?
| Isolierung | Typical R‑per‑inch | 72‑h likelihood | Was es bedeutet |
|---|---|---|---|
| EPS | ~3.6–3.9 | Possible (mehr Trockeneis) | Niedrigste Kosten; larger cube. |
| PUR/PIR | ~5.3–6.3 | Strong candidate | Dünnere Wände; geringeres Gewicht. |
| VIP | ~R‑30 (whole‑panel ≈R‑25–30) | Often 72–96 h+ | Smallest cube; weniger Eis. |
VIP and VIP‑hybrids often close a marginal 72‑h gap without excessive refrigerant, which aligns with off‑the‑shelf 72–96 h VIP kits used in food and life‑sciences.
Carrier rules for dry ice packs for shipping food 72 Std. (2025)
Luft (Iata, FedEx, UPS): Verwenden Hier ist PI954; Entlüftungsverpackung; anwenden Class9 Etikett; markieren "Trockeneis" oder "Kohlendioxid", solide,”Und 1845, und Netz kg. Hier ist 2025 acceptance checklist standardizes visual steps when no Shipper’s Declaration is required (for dry ice cooling non‑DG). FedEx 2025 Jobhilfen reiterate these marks and the per‑package maximum (often cited as 200 kg).
USPS (Hausluft): 5 lb max dry ice per mailpiece with required Pub 52 markings; surface mail has different marks.
UNS. Boden (49 CFR173.217): Not treated as fully regulated if minimum vented‑packaging/marking rules are met, but follow carrier SOPs.
UPS reminders: Nicht luftdicht verschließen; label “Dry Ice/UN1845”; expect acceptance audits on some services.
Checklist you can follow today: Verwenden Sie die belüftete Verpackung; apply Class 9; mark “UN 1845” + net kg on the same surface; train staff on current carrier/IATA rules.
Should you combine gel packs with dry ice packs for shipping food 72 Std.?
Ja-gel packs buffer temperatures and can slow dry‑ice burn‑off, useful for sensitive textures or long hot lanes. Carriers recognize dry ice and gel packs as common cooling aids; Cardinal Health’s guidance notes the combo can extend duration.
2025 developments and trends in dry‑ice food shipping
Was ist neu: Wider availability of curbside‑recyclable paper liners that rival EPS; VIP kits marketed for 72–96 h; cheaper connected data loggers; and clearer acceptance checklists in IATA DGR 66th (2025). Plan smaller cubes with higher R‑value and verify with data.
AT -A -Glance
-
Recycelbare Liner make EPS‑like performance possible with greener disposal.
-
VIP + PCM systems extend hold while cutting cube and dry‑ice mass.
-
Validation is mainstream: 72/144-H Ista7e profiles are the default for OQ.
Marktschnappschuss (directional): Cold‑chain data loggers projected ~7–8% CAGR durch 2030; insulated packaging continues steady growth mid‑single digits depending on region and segment. Use these as planning signals and confirm with your finance team.
Häufig gestellte Fragen

Ja, domestically—5 lb max dry ice per mailpiece by air with Pub 52 markings.
