Bulk Dry Ice Ice Pack: Cara Mengukur, Mengirimkan, dan Simpan

If you buy or ship a bulk dry ice ice pack, your biggest risks are temperature excursions, hazmat mistakes, and hidden cost. Es kering ada di –78.5 ° C. and sublimates to CO₂ gas, so sizing and labeling drive outcomes. Most validated shippers plan 5–10 lb per 24 jam dan menambahkan buffer; do the same and you’ll avoid claims and re-ships.

Ukuran yang tepat: A field-tested way to estimate bulk dry ice ice pack mass with a realistic buffer.
Kejelasan kepatuhan: The exact UN1845 wording and box markings you must show for air.
Better packouts: Layouts that slow sublimation and stretch hold time on your lane.
Smart alternatives: When gel or PCM beats a bulk dry ice ice pack for 2–8°C control.

How much bulk dry ice ice pack do you need for your lane?

Jawaban singkat: Sublimation rate × time + 20–25% penyangga. Typical planning ranges are 5–10 lb per 24 H Tergantung pada isolasi dan panas sekitar. Use the higher end for summer lanes or multi-stop air routes.

Metode rekayasa: Estimate heat load and divide by dry-ice sublimation energy (~ 571 kJ/kg), lalu tambahkan 10–15% batas. This method aligns sizing to your actual box and duration.

Kalkulator ukuran es kering (quick formula)

Kelas isolasi (pengirim)	Base rate (lb / 24 H)	24 h need (lb)	48 h need (lb)	72 h need (lb)	Apa artinya
EPS (dasar)	10	10–12	20–25	30–38	Murah, heavy ice usage
Rigid PU	7	7–9	14–18	21–27	Balanced choice
VIP + Pu	5	5–6	10–13	15–19	Higher box cost, lebih sedikit es

Practical packout tips that extend hold time

Pre-condition payload and liner.
Use thin slabs, not one block.
Control voids.
Always add a buffer.

Kasus dunia nyata: A biotech sender on a 72-hour route switched from EPS to VIP and cut the bulk dry ice ice pack from 36 lb ke 18 lb with zero excursions over 12 minggu -minggu.

What must go on a bulk dry ice ice pack label (UN1845)?

Untuk udara: Mencetak “Es kering” atau “karbon dioksida, padat,”UN1845, itu net dry-ice weight in kg, alamat pengirim/penerima, dan terapkan Kelas 9 label bahaya. Also put packages × kg on your air waybill.

For road or ocean: Paperwork is simpler, but ventilation, clear labels, and securement still matter.

When should you choose PCM or gel over a bulk dry ice ice pack?

Use a bulk dry ice ice pack for deep-frozen lanes (–40°C to –78.5°C). Use PCM or gel for tight 2–8 ° C. kontrol, berat badan lebih rendah, and simpler hazmat handling.

Side-by-side: which cold source fits your job?

Gunakan kasing	Es kering (UN1845)	Paket gel	Paket PCM	Pilihan terbaik
Es krim, daging beku	★★★★★	★★	★★★	Es kering
2–8°C vaccines/foods	★	★★★	★★★★★	PCM
Long air routes	★★★★	★★	★★★★	Dry ice/PCM
Hazmat simplicity	★	★★★★	★★★★	Gel/PCM
Weight constraints	★★	★★★	★★★★	PCM

How do you build a bulk dry ice ice pack system that lasts longer?

Tumpukan isolasi: PU walls (≥30 mm) dengan VIP lid/base if possible.
Tight lid geometry: Deep interlock lowers convection leaks.
Void control: Dunnage that doesn’t collapse at cold.
Thermal bridges: Isolate metal parts and straps.
Layering: Place dry ice above Dan around the load with separators.
Validasi: Run 23/30/40°C ambient profiles.

Layout options and expected duration

Tata Letak	Sublimation per 24 H	Lamanya	Penggunaan terbaik
Penempatan teratas	8–12%	24–36 h	Pengiriman singkat
Tata letak sekeliling	6–9%	36–60 h	Long-distance frozen goods
Hibrida (atas + sisi)	5–8%	48–72 jam	High-value critical goods

Tips yang dapat ditindaklanjuti

Pack above and around payloads.
Switch EPS→PU→VIP as your lane exceeds 48 jam.
Instrument the weak spot dengan logger.

Contoh Lapangan: Hybrid layout with PU walls extended route from 36 ke 60 hours without adding dry ice.

How do you stay safe when handling a bulk dry ice ice pack?

APD: Sarung tangan terisolasi dan pelindung mata.
Ventilasi: Avoid airtight rooms or containers.
Pembuangan: Let ice sublimate in open air.
Pelatihan: “Gloves on, lid open, head out.”

KPIs and troubleshooting

Melacak: tamasya per 100 Pengiriman, klaim, ice mass per lane, DIM vs. chargeable weight, siklus kembali.
Fix fast:
- Under-sized pack → increase buffer.
- Void issues → reduce air gaps.
- Label holds → reprint clear UN1845 labels.
- Hot hubs → add VIP lids or reschedule flights.

2025 cold-chain and bulk dry ice ice pack trends

Apa yang baru: Insulasi ramah lingkungan, Pemantauan IoT, and reusable boxes dominate 2025. Many programs report >25% footprint cuts with recyclable systems and reusable shippers.

Perkembangan terkini

Reusable fleets scale up.
PCM options expand.
Operator addenda stricter.

Gambaran pasar: Cold-chain packaging grows mid-single digits; PCM up double digits thanks to validation and lower per-use cost.

FAQ

How long does a bulk dry ice ice pack last?
Biasanya 24–72 jam tergantung pada isolasi dan beban.

What is the maximum dry ice allowed per air package?
Hingga ~200 kg, check your carrier.

Adalah es kering aman untuk pengiriman makanan?
Ya, if isolated and vented.

Can I reuse bulk dry ice ice pack pouches?
Yes—track reuse cycles and retire damage.

Ringkasan dan Rekomendasi

Size by rate × time + penyangga, label UN1845 perfectly, and switch chilled lanes to PCM jika memungkinkan. Improve insulation and track weak points for best results.
