Apa itu dry ice small pack—and when should you use it?

Paket kecil es kering adalah kompak, vented configuration that holds dry ice inside an insulated shipper to keep payloads ≤ −18 °C for 24–72 hours. Use it when the product must remain fully frozen end‑to‑end and your carrier accepts UN1845. Avoid sealed pouches; dry ice must vent as it sublimes to CO₂ gas.

In plain terms: gel packs hover near 0 °C; many PCMs hold +3/+5/+7/+17 °C—great for chilled lanes, not for hard‑frozen outcomes. Dry ice sits near −78.5 °C, giving you deep‑cold headroom through handoffs and door‑opens. Choose gel/PCM only when a chilled band is acceptable and you want to skip dangerous‑goods handling.

Dry ice small pack vs. gel/PCM for common parcel goals

Intinya: pick the tool that matches your temperature goal and acceptance constraints.

Gunakan kasing (sasaran)	Best pick	Durasi khas	Apa artinya ini bagi Anda
Es krim, daging (stay frozen)	Dry ice small pack	24–72H	Requires venting + UN1845/Class 9 by air; robust frozen integrity.
2–8 °C pharma or meal kits	+5 °C PCM or gel	12–96h	Tight, non‑frozen band; simpler handling and labeling.
Heat‑sensitive confection (+17 ° C.)	+17 ° C PCM	24–72H	Avoids bloom; validate in hot lanes before scale‑up.

Tip Praktis untuk Anda

Lubang angin, don’t seal: never heat‑seal dry ice in plastic; use vent‑friendly pouches or paper bags.
Prasyarat: freeze product ≤ −18 °C and pre‑chill the shipper to extend hold time.
Distribute mass: split dry ice into multiple smaller packs and place some on top to reduce hot spots.

Real‑world snapshot: A bakery shipped croissants with two vented paper bags (~6 lb total) inside an EPS shipper. With UN1845/Class 9 labels, the box held below −15 °C for 36 hours and passed acceptance on the first attempt.

How much dry ice small pack do you need for 24–72 hours?

Fast rule‑of‑thumb: rencana 5–10lb (2.3–4.5kg) per 24 hours in a parcel‑size cooler. Use the high end for hot lanes or frequent door‑opens, dan tambahkan hari penyangga untuk penundaan.

Physics‑first estimator (more precise): dry ice absorbs about 571 kJ/kg as it sublimes. Multiply your hourly heat leak by transit hours, then divide by 571, and add a 10–20% buffer. It’s a reliable starting point before lane testing.

Suggested starting ranges (tune after your first lane test):

Lamanya	Lembut (≤22 ° C.)	Hangat (23–30 ° C.)	Panas (≥31 ° C.)	Mengapa ini penting
~ 24h	2–3kg	3–5kg	5–6kg	Split into ≥ 2 packs; add top coverage.
~ 48h	4–6kg	6–8kg	8–11kg	Add side + top packs for stability.
~ 72h	6–8kg	9–12kg	12–15kg	Consider larger box or better insulation.

Penempatan & box size (practical details)

Box volume: 10–20 L shippers are common for a dry ice small pack. Larger boxes increase heat load.
Layering: bottom bag → payload → top bag; add side bags for > 48h. Fill voids to slow convection.
Hybrid trick: a thin −20 °C PCM touching the product can smooth door‑opens while keeping dry ice mass modest.

How to pack and label a dry ice small pack in 2025?

Core compliance (udara): use packaging that permits CO₂ release, tanda “Karbon dioksida, padatan "atau" es kering " + UN1845 + Kg net, dan terapkan a Label Class9 on the same face. Gunakan IATA PI954 acceptance checklist at tender. Sealed plastic bags are prohibited.

Step‑by‑step SOP you can paste into your manual:

Prepare vent‑friendly pouches (paper dry‑ice bags or sleeves). Melakukan bukan seal dry ice airtight.
Layer dengan cerdas: bottom pack → payload → top pack; add sides for longer lanes.
Vent the outer shipper: close firmly but avoid airtight seals; meninggalkan jalur gas.
Label clearly: UN1845 proper name + Kg net + Label Class9 (≥100mm).
Book correctly: some operators ask for net kg at booking to manage aircraft limits.

Udara, tanah, USPS, and passenger nuances

Passenger travel: ≤2.5kg (5.5 lb) per passenger/package with airline approval; the package must vent and be marked.
USPS Air Mail: ≤ 5 lb dry ice per mailpiece under Packaging Instruction 9A; venting and markings required.
Carrier notes: FedEx reiterates no sealed plastic and cites a 200 kg/package ceiling (well above small‑pack needs). UPS/express networks mirror PI 954 venting and marking rules.

Dry ice small pack safety: Aturan sederhana yang mencegah insiden

Short list that saves headaches: ventilate the room, wear insulated gloves and eye protection, and never trap CO₂ in sealed layers. Train staff to handle small pieces with tongs and to avoid packing in enclosed vehicles or cold rooms with poor airflow.

Quick safety checklist

Vent every layer: pouch → inner liner (open) → outer shipper (ventilasi).
APD: cryo‑compatible gloves, safety glasses minimum.
No airtight seals: never heat‑seal dry ice in plastic; meninggalkan jalur gas.
Staging areas: keep out of confined spaces; CO₂ can pool low and displace oxygen.

2025 dry ice small pack updates and trends

Apa yang baru: 2025 operator job aids emphasize kemasan ventilasi, clear UN1845 marks, and providing net kg at booking. Expect acceptance audits that verify PI 954 checklists even for very small parcels. Retail dry ice availability remains strong through major grocers for last‑minute top‑ups.

Perkembangan terbaru sekilas

Stronger documentation: IATA’s 66th‑edition addendum tightened booking data requests for dry ice.
Safer packouts: carrier pages stress no sealed plastic and adequate venting.
Chilled alternatives mature: +3/+5/+7/+17 °C PCMs now cover many non‑frozen lanes without DG handling.

Wawasan pasar: shippers increasingly reserve a dry ice small pack for true frozen lanes and shift 2–8 °C work to PCMs to reduce labels, biaya tambahan, and exception risk—all while maintaining product integrity.
