Pacote de transporte de gelo seco: How to Size and Label in 2025
If you need a dry ice shipping pack that actually stays frozen, start by sizing dry ice to transit hours, escolhendo o isolamento certo, and printing UN 1845 with net kilograms on a vented box. Most lanes work with 5–10 lb por 24 horas mais um buffer de 24 horas, e 2025 checklists require clear labels and vent paths for CO₂.

O que é a dry ice shipping pack e quando você deve usá-lo?
Resposta curta: UM dry ice shipping pack é um ventilado, insulated parcel that keeps payloads rock‑solid frozen using solid CO₂ (sublimes at −78.5 °C). Use it when your product must arrive fully frozen end‑to‑end; otherwise consider gel/PCM if chilled control is enough. Marca “Gelo seco/dióxido de carbono, sólido,”E 1845, e net kg, and ensure gas can vent.
Por que isso importa para você: A ventilação evita o acúmulo de pressão; correct markings speed acceptance and reduce delays. 2025 acceptance materials emphasize airline‑specific limits and providing net weight at booking, enquanto USPS caps domestic air mail at ≤5 lb per piece and prohibits international mail with dry ice. If your lane is short or only needs chilled ranges, a gel/PCM pack avoids hazmat steps.
Dry ice shipping pack vs. gel/PCM—what fits your lane?
Choose a dry ice shipping pack when you need deep‑frozen conditions or ultracold lanes; escolha gel/PCM when you need 2–8 °C or moderate frozen (por exemplo, −15°C) with simpler paperwork. Larger pellets or blocks sublimate slower for multi‑day routes; tiny pellets are better for fast pull‑down.
| Opção | Temp capability | Pátria (ar) | O que isso significa para você |
|---|---|---|---|
| Dry ice shipping pack | ≈ −78.5 °C surface | Sim | Longas esperas; ultracold lanes; rótulo & ventilação necessária. |
| PCM -21 ° C. / −26 °C bricks | Congelado (−15 to −26) | Geralmente não | Easier processing; reutilizável; não ultrafrio. |
| 0 Venha ° c / +5 ° C PCM | 2–8 ° C. | Não | Produtos refrigerados; simple returns. |
Dicas práticas que você pode usar hoje
-
For DTC frozen food: Pré-resfrie o remetente; place product low, gelo seco acima; preencher vazios; deixe as aberturas desobstruídas.
-
Para pistas quentes (verão): Use o high end of 5–10 lb/day and consider PUR or VIP insulation.
-
Para produtos biológicos: Add a data logger and record gelo seco da rede em kg on the label before tender.
Caso do mundo real: A pastry brand cut melted‑product claims by 38% after switching to a 2‑inch liner, larger pellets, and a 24‑hour buffer—ice spend stayed flat while failures plummeted.
How much dry ice should a dry ice shipping pack carry?
Regra geral: Plano ~ 5-10 lb. (2.3–4,5 kg) por 24 horas de trânsito plus an extra 24 horas para buffer. Comece próximo 7.5 lb/dia e ajuste para isolamento, calor ambiente, Tamanho do pellet, and whether the box is opened mid‑route.
Por que funciona: Dry ice absorbs substantial heat while subliming (≈570 kJ/kg), so modest masses can cover a day or two in a tight shipper. Box R‑value, Headspace, and pellet size drive real‑world loss rates.
Quick planner table
| Tempo de trânsito | Gelo seco típico (Libra) | Notas |
|---|---|---|
| 12–24 h | 5–10 | Thick foam → 5; summer lanes → 10. |
| 24–48 h | 10–20 | Prefer larger pellets for slower loss. |
| 72 h | 20–30 | Consider bigger box or added liner. |
| 96 h | 30–40 | Validate with a lane test before scale. |
How should you label a dry ice shipping pack in 2025?
Print this on one panel (same surface as Class 9 when size allows):
E 1845
Dióxido de carbono, sólido (Gelo seco)
Gelo seco da rede: ____ kg
Remetente: ____________________
Consignatário: ____________________
Para ar, Aplique o Classe9 Diamond, Continue embalando ventilado, and follow IATA PI954. Airlines may impose additional limits and ask for net weight at booking. USPS permits ≤5 lb domestic air under PI 9A and prohibits international mail. Passenger flights allow ≤2.5 kg per person/package with airline approval and venting.
How do you pack out a dry ice shipping pack step by step?
-
Pré -Chill product and shipper to reduce the day‑one heat load.
-
Linha & isolar: add a poly liner and absorbent pad; place a tray to avoid direct contact.
-
Carregar: produto baixo, gelo seco acima; fill voids to reduce convection.
-
Fechar & ventilação: never seal the outer box airtight; keep gas paths clear of tape.
-
Rótulo & book: marca E 1845 com NET KG, adicionar Classe9 para o ar, e siga o 2025 Lista de verificação de aceitação.
Safety and ventilation: CO₂ limits to respect
Gelo seco se transforma em gás CO₂. Indoors or in vehicles, gas can accumulate. Keep rooms ventilated and train staff. Reference limits: 5,000 ppm twa e 30,000 ppm stel; add CO₂ alarms in staging areas. Always use insulated gloves and eye protection.
Which insulation and pellet size fit your dry ice shipping pack?
Pick insulation for duration e pellet size for endurance. EPS works for short lanes; PUR and VIP cut heat gain for 48–120 h routes and allow less refrigerant mass. Larger pellets or slabs sublimate slower on multi‑day lanes.
| Tipo de pacote | Janela típica | Notas | Significado para você |
|---|---|---|---|
| EPS (1–2″) | 24–48 h | Lowest R‑value; lowest cost | Bom para pistas curtas; mais gelo seco necessário. |
| Pur | 48–96 h | Higher R/inch; consistente | Reduce mass and carton size. |
| VIP | 72–120 h+ | Very high performance | Pistas longas, high value payloads; lighter overall. |
2025 trends shaping your dry ice shipping pack
O que há de novo 2025: IATA’s 66th Edition Adenda 1 (effective Apr 30, 2025) highlights airline‑specific dry ice limits and net weight at booking; carriers refreshed job aids stressing Class 9 placement with the Proper Shipping Name. USPS kept the ≤5 lb domestic air cap. VIP adoption keeps rising to trim refrigerant mass and freight.
